Key Takeaways from the Webinar – Digital Health Beyond COVID-19: Bringing the Hospital to the Customer

The outbreak of pandemic COVID-19 put the healthcare sector into a tizzy. From dealing with a rising number of patients and lack of medical supplies and infrastructure to falling in-patient and out-patient footfalls and elective surgeries; it was indeed a difficult period. The latter affected the business of private healthcare due to their inability to […]

Virtual Care, Telehealth, Telemedicine, etc. are terms used very synonymously. Indeed they are interrelated, however, Virtual Care is a broader term in which healthcare providers use digital tools to communicate and deliver care to their patients. Telehealth and Telemedicine are a part of Virtual Care where doctors deliver care to their patients, remotely via phone, video, or instant messaging. Virtual health includes care delivery beyond video consultation where hospitals provide services using technology such as wearables for remote monitoring, instruments for post-op care and second opinions, e-pharma services, and medical information, etc. 

The outbreak of the COVID-19 pandemic gave an impetus to Virtual Care, but even in the Pre-COVID time, the Healthcare sector was slowly gearing up for this next wave in care delivery. What COVID-19 did was, help patients get acclimatized to the digital health tools and services. 

What does Virtual Health help with?

The pandemic has brought the burning issues of the healthcare sector to center stage. Patient experience and access to healthcare services are key differentiators for people while choosing a healthcare provider. Let’s take a look at some of these issues addressed by technology in the healthcare sector-

The increasing number of patients

Apart from the pandemic, there’s already been a rise in the number of patients due to drastic changes in lifestyle and food habits, an increase in pollution levels, increase in new types of viruses, etc. This has caused undue stress on healthcare institutions and workers and has led to the deterioration of the quality of patient care. Virtual Health technology such as mobile healthcare apps, EHR (Electronic Health Record), video conferencing, etc. has helped reduce the pressure on hospitals.

Difficulty in traveling for old patients

The pace of life is increasing at a rapid rate. It is getting insanely difficult for the elder population to navigate through the traffic and commute long distances for a check-up. Many times, they have to depend on their family members to take them to hospitals. Moreover, they are at risk of exposure to viruses in hospitals and clinics. Now that they have had the experience of virtual consultations, they prefer care delivery at home rather than going to hospitals.

Chronic Diseases treatment

The number of people above the age of 45 face health issues. Some patients are suffering from chronic diseases regardless of age. Regular monitoring of their vitals is very important. Moreover people now prefer Virtual healthcare services which are easily accessible and save a lot of time, effort, and money. Now that people have found these services effective, they will opt for online consults rather than frequent in-person visits. 

Post-op Care

The duration of post-operative care is quite long and tedious. If given a choice, people will lean towards wearables which will help keep doctors posted on the status of the treatment. Many times, the cost of post-op care is more than the actual treatment and sometimes is not covered under insurance. Virtual care-delivery services will help reduce the financial burden of people going through these treatments.

Follow-ups/Second opinion  

Some health conditions need multiple follow-ups and second opinions to figure out the right approach to treat the issue. It is much easier for patients to do follow-up consults virtually rather than going through the tedious process of appointment booking, commuting, and waiting for their turn. It helps reduce the queue outside the doctor’s office as well. Some health issues need a second opinion, sometimes both by patients and doctors. Virtual Healthcare technologies make it possible for them to take second opinions from doctors all over the world. With electronic records and image sharing, doctors can diagnose the problem better.

What does Virtual Health include?

Virtual Health can be broadly divided into below applications-

mHealth Applications

Mobile health applications have widespread use. From symptom checkers to appointment booking, from fitness trackers to uploading medical records, from video conferencing features to chatbot integrations, mobile healthcare apps in India are on a rise mainly because of easy accessibility for the tech-savvy customers. According to a study by NCBI, among the 22 selected mobile healthcare apps in India, Practo, mfine, DocsApp, 1mg, Netmeds, Lybrate, MediBuddy, and Medlife were found to be the eight most popular ones with over a million downloads and on average four-plus user rating out of five. All the above apps are mainly being used for online consults. This just goes about showing that people prefer having homecare services instead of stepping out. 

E-Triage Tools

The rising number of patients with different stages of COVID symptoms was a task to deal with. E-triage software here enables hospitals to triage patients into different sections when there’s an overload of patients at a particular time. Now, in the case of home care, e-triage tools help patients to access the gravity of their health condition and notify the healthcare provider accordingly. Such tools help reduce A&E waiting time and improve NHS performance. Many companies are building healthcare software integrating the E-triage module within EHR, telemedicine, clinical decision making, billing, etc. In India, Persistent Systems’ cutting edge platform has a Nurse Triage system that enables nurses to see the queue of patients and triage via phone calls. Once the calls are done, a triage report is generated and sent to care providers. Many leading doctors feel that AI in image triage will see a boost in near future.

Remote Patient Monitoring 

There are multiple benefits such as reduced post-op expenditure, time wastage, less exposure to other diseases, etc. The global remote patient monitoring devices market is expected to expand at a CAGR of 7.1% during the forecast period (2019–2027) according to Coherent Market Insights. Some of the top players in this space are Biotronik, Boston Scientific Corporation, CAS Medical Systems, CONTEC MEDICAL, Dragerwerk, GE Healthcare, Guangdong Biolight Meditech, Medtronic, Mindray Medical, Nihon Kohden, Philips Healthcare, Spacelabs Healthcare, Abbott. Companies such as GE Healthcare and Philips Healthcare have done a great job with building remote patient monitoring systems within the hospital premises as well as homecare for COVID patients. The main goal was to reduce the exposure of healthcare workers to at-risk patients. 

Synchronous and Asynchronous Telehealth

Synchronous telehealth, in other words, Telemedicine is where there is a live conversation between the patient and the doctor. Asynchronous telehealth involves the exchange of recorded data e.g. images, video, medical reports, pathology reports between patients and doctors, at times between doctors as well. Similar to mHealth space, companies like Practo, 1mg, Lybrate, Medlife, and Portea Medical in India are some of the top players in telehealth and telemedicine. Lybrate’s USP lies in CMS (Clinical Management System) which helps doctors with tedious tasks of managing patients and providing better care. Meanwhile, Portea Medical’s home consults and pharma delivery have more relevance with the audience as it combines technology with a touch of personalization. 

Digital Therapeutics

Digital Therapeutics delivers evidence-based therapies with the help of software which can be used both as a preventive measure as well as treatment application. The effectiveness of the medication and lifestyle changes on patients are monitored by leveraging technology. In India, major non-communicable diseases that account for 62% of the total mortality rate are CVD, diabetes, respiratory conditions, and cancer. Prominent global players in this space include Noom (US), Livongo Health (US), Omada Health (US), WellDoc (US), Pear Therapeutics (US), Proteus Digital Health (US), Propeller Health (US), Akili Interactive Labs (US), Better Therapeutics (US), etc. Omada Health is the pioneer in the DTx (Digital Therapeutics) that focused primarily on diabetes and pre-diabetes but now is branching out in the mental health space as well. In India, Altran (a part of Capgemini) is into building personalized DTx applications for clients. Whereas a start-up called Wellthy Therapeutics has ready solutions catering to multiple diseases.

Future of Virtual Health

Undoubtedly, there has been a massive increase in the adoption of Virtual Health technologies as people have gotten accustomed to the ease of certain services at home. In the coming future, mobile health apps, remote patient monitoring, and Digital therapeutics see a surge in demand from the customers. According to a study by Markets and Markets, “The global digital therapeutics market is projected to reach USD 6.9 billion by 2025 from USD 2.1 billion in 2020, at a CAGR of 26.7% during the forecast period (2020–2025).” A study by Fortune Business Insights, “The global mHealth market size is projected to reach USD 293.29 billion by 2026, exhibiting a CAGR of 29.1% during the forecast period.” A Research and Markets report says, “The remote patient monitoring market is expected to reach US$31.326 billion by the end of 2023.” Apart from the above, development in digital infrastructure such as virtual health stations where doctors can provide consultations globally, mobile ICUs, MRIs, X-rays, ultrasound equipment, the establishment of rural virtual care units reaching the remote areas of the country are some of the trends which will gain momentum. The focus would always lie upon the personalization of the virtual care experience for patients driven by data exchange and interoperability. 

Indeed, there are certain challenges to the implementation of these technologies, lack of infrastructure, and digital literacy amongst elders and lower strata of society. Many healthcare institutions still have inhibitions while investing in digital technologies fearing rejection from the customers. It will be crucial for care providers to choose the right partner for implementing these technologies and create awareness amongst people to adopt them.  

In a Nutshell

The success of virtual care relies on how well the digital experience is designed for the patient. “By 2025, as many as 95 percent of all customer interactions will be through channels supported by artificial intelligence (AI) technology” – Microsoft. The use of algorithms and AI for personalizing these experiences will be the key.

Are Chatbots Vulnerable? Best Practices to Ensure Chatbots Security

Published

on

Rebecca James

A simple answer is a Yes! Chatbots are vulnerable. Some specific threats and vulnerabilities risk chatbots security and prove them a wrong choice for usage. With the advancement in technology, hackers can now easily target the hidden infrastructure of a chatbot.

The chatbot’s framework has an opportunity for the attackers ready to inject the malicious codes or commands that might unlock the secured data of the customers and your business. However, the extent of the attack’s complexity and success might depend on the messaging platform’s security.

Are you thinking about how chatbots are being exposed to attacks? Well! Hackers are now highly advanced. They attack the chatbots in two ways, i.e., either by social engineering attack or by technical attacks.

  • An evil bot can impersonate a legal user by using backup data of the possibly targeted victims by social engineering attack. All such data is collected from various sources like the dark web and social media platforms. Sometimes they use both sources to gain access to some other user’s data by a bot providing such services.
  • The second attack is technical. Here also attackers can turn themself into evil bots who exchange messages with the other bots. The purpose is to look for some vulnerabilities in the target’s profile that can be later exploited. It can eventually lead to the compromise of the entire framework that protects the data and can ultimately lead to data theft.

To ensure chatbots security, the bot creators must ensure that all the security processes are in place and are responsible for restoring the architecture. The data flow via the chatbot system should also be encrypted both in transit and rest.

To further aid you in chatbot security, this article discusses five best practices to ensure chatbots security. So, let’s read on.

The following mentioned below are some of the best practices to ensure the security of chatbots.

It’s always feared that data in transit can be spoofed or tampered with the sophistication of cybercriminals’ technology and smartness. It’s essential to implement end-to-end encryption to ensure that your entire conversation remains secured. It means that by encryption, you can prevent any third person other than the sender and the receiver from peeping into your messages.

Encryption importance can’t be neglected in the cyber world, and undoubtedly the chatbot designers are adapting this method to make sure that their chatbot security is right on the point. For more robust encryption, consider using business VPNs that encrypt your internet traffic and messages. With a VPN, you can also prevent the threats and vulnerabilities associated with chatbots.

Moreover, it’s a crucial feature of other chat services like WhatsApp and other giant tech developers. They are anxious to guarantee security via encryption even when there’s strict surveillance by the government. Such encryption is to fulfill the legal principles of the GDPR that says that companies should adopt measures to encrypt the users’ data.

User identity authentication is a process that verifies if the user is having secure and valid credentials like the username and password. The login credentials are exchanged for having a secure authentication token used during the complete user session. If you haven’t, then you should try out this method for boosting user security.

Authentication timeouts are another way to ensure your chatbots security. This method is more common in banks as the token can be used for the predetermined time.

Moreover, two-factor authentication is yet another method to prove user identity. Users are asked to verify identity either by a text message or email, depending on the way they’ve chosen. It also helps in the authorization process as it permits access to the right person and ensures that information isn’t mishandled or breached.

The self-destructive message features open another way for enhancing chatbot security. This option comes in handy when the user provides their personally identifiable information. Such information can pose a serious threat to user privacy and should be destroyed or deleted within a set period. This method is handier when you’re associated with backing or any other financial chatbots.

By using secure protocols, you can also ensure chatbots security. Every security system, by default, has the HTTPS protocol installed in it. If you aren’t an IT specialist, you can also identify it when you view the search bar’s URL. As long as your data is being transferred via HTTPS protocol and encrypted connections, TLS and SSL, your data is secured from vulnerabilities and different types of cyber-attacks.

Thus, make sure to use secure protocols for enhanced security. Remember that when Chatbots are new, the coding and system used to protect it is the same as the existing HIMs. They interconnect with their security systems and have more than one encryption layer to protect their users’ security.

Do you know what the most significant security vulnerability that’s challenging to combat is? Wondering? Well! It’s none other than human error. User behavior must be resolved using commercial applications because they might continue to believe that the systems are flawed.

No doubt that an unprecedented number of users label the significance of digital security, but still, humans are the most vulnerable in the system. Chatbot security continues to be a real big problem until the problem of user errors comes to an end. And this needs education on various forms of digital technology, including chatbots.

Here the customers aren’t the ones who are to be blamed. Like customers, employees can make a mistake, and they do make most of the time. To prevent this, the chatbot developers should form a defined strategy, including the IT experts, and train them on the system’s safe use. Doing so enhances the team’s skillset and allows them to engage with the chatbot system confidently.

However, clients can’t be educated like the employees. But at least you can provide them a detailed road map of securely interacting with the system. It might involve other professionals who can successfully engage customers and educate them on the right way to interact with the chatbots.

Several emerging technologies are keen to play a vital role in protecting the chatbots against threats and vulnerabilities in the upcoming time, among all the most potent method behavior analytics and Artificial Intelligence developments.

  • User Behavioral Analytics: It’s a process that uses applications to study the patterns of user behavior. It enables them to implement complex algorithms and statistical analysis to detect any abnormal behavior that possibly represents a security threat. Analytical tools are quite common and powerful; thus, this methodology can become a fundamental component of the chatbot system.
  • Developments in AI: Artificial technology is a two-end sword that offers benefits and threats simultaneously. But, as AI is predicted to fulfill its potential, it will provide an extra security level to the systems. It is mainly because of its ability to wipe a large amount of data for abnormalities that recognizes security breaches and threats.

The Bottom Line

Security concerns have always been there with new technologies and bring new threats and vulnerabilities with them. Although chatbots are an emerging technology, the security practices that stand behind them are present for a long time and are effective. Chatbots are the innovative development of the current era, and emerging technologies like AI will transform the way businesses might interact with the customers and ensure their security.

What’s the Best Tech Stack for Mobile App Development? Read To Know

Which is the Best Tech Stack for Mobile Application Development? Kotlin, React Native, Ionic, Xamarin, Objective-C, Swift, JAVA… Which One?

Image Source: Google

Technology Stack for smartphones is like what blood is for the human body. Without a technology stack, it is hard even to imagine smartphones. Having a smartphone in uncountable hands is rising exponentially. For tech pundits, this is one unmissable aspect of our digital experience wherein tech stack is as critical as ROI.

The riveting experience for a successful mobile app predominantly depends on technology stacks.

The unbiased selection of mobile apps development language facilitates developers to build smooth, functional, efficient apps. They help businesses tone down the costs, focus on revenue-generation opportunities. Most importantly, it provides customers with jaw-dropping amazement, giving a reason to have it installed on the indispensable gadget in present times.

In today’s time, when there are over 5 million apps globally, and by all conscience, these are whopping no.s and going to push the smartphone industry further. But now you could see mobile app development every ‘nook and corner.’ But the fact is not who provides what but understanding the behavioural pattern of users.

So the pertinent question is, which is the ideal tech stack to use for mobile app development?

In native mobile app development, all toolkits, mobile apps development language, and the SDK are supported and provided by operating system vendors. Native app development thus allows developers to build apps compatible with specific OS environments; it is suitable for device-specific hardware and software. Hence it renders optimized performance using the latest technology. However, since Android & iOS imparts — — a unique platform for development, businesses have to develop multiple mobile apps for each platform.

1. Waz

2. Pokemon Go

3. Lyft

1.Java: The popularity of JAVA still makes it one of the official programming languages for android app development until the introduction of Kotlin. Java itself is at the core of the Android OS. Many of us even see the logo of Java when the device reboots. However, contradictions with Oracle (which owns the license to Java) made Google shift to open-source Java SDK for versions starting from Android 7.0 Nougat

2.Kotlin: According to Google I/O conference in 2019- Kotlin is the officially supported language for Android app development. It is entirely based on Java but has a few additions which make it simpler and easier to work.

It’s my gut feeling like other developers to say that Kotlin is simply better. It has a leaner, more straightforward and concise code than open-cell Java, and several other advantages about handling null-pointer exceptions and more productive coding.

HERE’S A Programming Illustration Defining the CONCISENESS OF KOTLIN CODE

public class Address {

private String street;

private int streetNumber;

private String postCode;

private String city;

private Country country;

public Address(String street, int streetNumber, String postCode, String city, Country country) {

this.street = street;

this.streetNumber = streetNumber;

this.postCode = postCode;

this.city = city;

this.country = country;

}

@Override

public boolean equals(Object o) {

if (this == o) return true;

if (o == null || getClass() != o.getClass()) return false;

Address address = (Address) o;

if (streetNumber != address.streetNumber) return false;

if (!street.equals(address.street)) return false;

if (!postCode.equals(address.postCode)) return false;

if (!city.equals(address.city)) return false;

return country == address.country;

}

@Override

public int hashCode() {

int result = street.hashCode();

result = 31 * result + streetNumber;

result = 31 * result + postCode.hashCode();

result = 31 * result + city.hashCode();

result = 31 * result + (country != null ? country.hashCode() : 0);

return result;

}

@Override

public String toString() {

return “Address{“ +

“street=’” + street + ‘\’’ +

“, streetNumber=” + streetNumber +

“, postCode=’” + postCode + ‘\’’ +

“, city=’” + city + ‘\’’ +

“, country=” + country +

‘}’;

}

public String getStreet() {

return street;

}

public void setStreet(String street) {

this.street = street;

}

public int getStreetNumber() {

return streetNumber;

}

public void setStreetNumber(int streetNumber) {

this.streetNumber = streetNumber;

}

public String getPostCode() {

return postCode;

}

public void setPostCode(String postCode) {

this.postCode = postCode;

}

public String getCity() {

return city;

}

public void setCity(String city) {

this.city = city;

}

public Country getCountry() {

return country;

}

public void setCountry(Country country) {

this.country = country;

}

}

class Address(street:String, streetNumber:Int, postCode:String, city:String, country:Country) {

var street: String

var streetNumber:Int = 0

var postCode:String

var city: String

var country:Country

init{

this.street = street

this.streetNumber = streetNumber

this.postCode = postCode

this.city = city

this.country = country

}

public override fun equals(o:Any):Boolean {

if (this === o) return true

if (o == null || javaClass != o.javaClass) return false

Val address = o as Address

if (streetNumber != address.streetNumber) return false

if (street != address.street) return false

if (postCode != address.postCode) return false

if (city != address.city) return false

return country === address.country

}

public override fun hashCode():Int {

val result = street.hashCode()

result = 31 * result + streetNumber

result = 31 * result + postCode.hashCode()

result = 31 * result + city.hashCode()

result = 31 * result + (if (country != null) country.hashCode() else 0)

return result

}

public override fun toString():String {

return (“Address{“ +

“street=’” + street + ‘\’’.toString() +

“, streetNumber=” + streetNumber +

“, postCode=’” + postCode + ‘\’’.toString() +

“, city=’” + city + ‘\’’.toString() +

“, country=” + country +

‘}’.toString())

}

}

I’d say KOTLIN IS THE BEST FIND FOR ANDROID APP DEVELOPMENT.Google has dug deeper with some plans ahead since announcing it as an official language. Moreover, it signals Google’s first steps in moving away from the Java ecosystem, which is imminent, considering its recent adventures with Flutter and the upcoming Fuchsia OS.

Objective C is the same for iOS what Java is for Android. Objective-C, a superset of the C programming language( with objective -oriented capabilities and dynamic run time) initially used to build the core of iOS operating system across the Apple devices. However, Apple soon started using swift, which diminishes the importance of Objective -C in comparison to previous compilations.

Apple introduced Swift as an alternative to Objective-C in late 2015, and it has since been continued to be the primary language for iOS app development.Swift is more functional than Objective-C, less prone to errors, dynamic libraries help reduce the size and app without ever compromising performance.

Now, you would remember the comparison we’ve done with Java and kotlin. In iOS, objective-C is much older than swift with much more complicated syntax. Giving cringeworthy feel to beginners to get started with Objective-C.

THIS IS WHAT YOU DO WHEN INITIALIZING AN ARRAY IN OBJECTIVE-C:

NSMutableArray * array =[[NSMutableArray alloc] init];

NOW LOOK AT HOW THE SAME THING IS DONE IN SWIFT:

var array =[Int]()

SWIFT IS MUCH MORE ` WHAT WE’VE COVERED HERE.

In cross-platform app development, developers build a single mobile app that can be used on multiple OS platforms. It is made possible by creating an app with a shared common codebase, adapted to various platforms.

Popular Cross-platform apps:

  1. Instagram
  2. Skype
  3. LinkedIN

React Native is a mobile app development framework based on JavaScript. It is used and supported by one of the biggest social media platforms- Facebook. In cross-platform apps built using React Native, the application logic is coded in JavaScript, whereas its UI is entirely native. This blog about building a React Native app is worth reading if you want to know why its stakes are higher.

Xamarin is a Microsoft-supported cross-platform mobile app development tool that uses the C# programming language. Using Xamarin, developers can build mobile apps for multiple platforms, sharing over 90% of the same code.

TypeScript is a superset of JavaScript, and is a statically-typed programming language supported by Microsoft. TypeScript can be used along with the React Native framework to make full use of its error detection features when writing code for react components.

In Hybrid mobile app development, developers build web apps using HTML, CSS & JavaScript and then wrap the code in a native shell. It allows the app to be deployed as a regular app, with functionality at a level between a fully native app and a website rendered(web browser).

Apache Cordova is an open-source hybrid mobile app development framework that uses JavaScript for logic operations and while HTML5 & CSS3 for rendering. PhoneGap is a commercialized, free, and open-source distribution of Apache Cordova owned by Adobe. The PhoneGap platform was developed to deliver non-proprietary, free, and open-source app development solutions powered by the web.

Ionic is a hybrid app development framework based on AngularJS. Similar to other hybrid platforms, it uses HTML, CSS & JavaScript to build mobile apps. Ionic is primarily focused on the front-end UI experience and integrates well with frameworks such as Angular, Vue, and ReactJS.

To summarize, there are 3 types of mobile apps- Native mobile apps, Cross-platform mobile apps, and Hybrid mobile apps; each offers unique technologies, frameworks, and tools of their own. I have enlisted here the best mobile app technology stacks you could use for mobile app development.

The technologies, tools, and frameworks mentioned here are used in some of the most successful apps. With support from an expert, a well-established mobile app development company, that may give much-needed impetus in the dynamic mobile app development world.

Arcanum specializes in digitizing Hungarian language content, including newspapers, books, maps, and art. With over 30 years of experience, Arcanum serves more than 30,000 global subscribers with access to Hungarian culture, history, and heritage.

Amazon Rekognition Solutions Architects worked with Arcanum to add highly scalable image analysis to Hungaricana, a free service provided by Arcanum, which enables you to search and explore Hungarian cultural heritage, including 600,000 faces over 500,000 images. For example, you can find historical works by author Mór Jókai or photos on topics like weddings. The Arcanum team chose Amazon Rekognition to free valuable staff from time and cost-intensive manual labeling, and improved label accuracy to make 200,000 previously unsearchable images (approximately 40% of image inventory), available to users.

Amazon Rekognition makes it easy to add image and video analysis to your applications using highly scalable machine learning (ML) technology that requires no previous ML expertise to use. Amazon Rekognition also provides highly accurate facial recognition and facial search capabilities to detect, analyze, and compare faces.

Arcanum uses this facial recognition feature in their image database services to help you find particular people in Arcanum’s articles. This post discusses their challenges and why they chose Amazon Rekognition as their solution.

Automated image labeling challenges

Arcanum dedicated a team of three people to start tagging and labeling content for Hungaricana. The team quickly learned that they would need to invest more than 3 months of time-consuming and repetitive human labor to provide accurate search capabilities to their customers. Considering the size of the team and scope of the existing project, Arcanum needed a better solution that would automate image and object labelling at scale.

Automated image labeling solutions

To speed up and automate image labeling, Arcanum turned to Amazon Rekognition to enable users to search photos by keywords (for example, type of historic event, place name, or a person relevant to Hungarian history).

For the Hungaricana project, preprocessing all the images was challenging. Arcanum ran a TensorFlow face search across all 28 million pages on a machine with 8 GPUs in their own offices to extract only faces from images.

The following screenshot shows what an extract looks like (image provided by Arcanum Database Ltd).

The images containing only faces are sent to Amazon Rekognition, invoking the IndexFaces operation to add a face to the collection. For each face that is detected in the specified face collection, Amazon Rekognition extracts facial features into a feature vector and stores it in an Amazon Aurora database. Amazon Rekognition uses feature vectors when it performs face match and search operations using the SearchFaces and SearchFacesByImage operations.

The image preprocessing helped create a very efficient and cost-effective way to index faces. The following diagram summarizes the preprocessing workflow.

As for the web application, the workflow starts with a Hungaricana user making a face search request. The following diagram illustrates the application workflow.

The workflow includes the following steps:

  1. The user requests a facial match by uploading the image. The web request is automatically distributed by the Elastic Load Balancer to the webserver fleet.
  2. Amazon Elastic Compute Cloud (Amazon EC2) powers application servers that handle the user request.
  3. The uploaded image is stored in Amazon Simple Storage Service (Amazon S3).
  4. Amazon Rekognition indexes the face and runs SearchFaces to look for a face similar to the new face ID.
  5. The output of the search face by image operation is stored in Amazon ElastiCache, a fully managed in-memory data store.
  6. The metadata of the indexed faces are stored in an Aurora relational database built for the cloud.
  7. The resulting face thumbnails are served to the customer via the fast content-delivery network (CDN) service Amazon CloudFront.

Experimenting and live testing Hungaricana

During our test of Hungaricana, the application performed extremely well. The searches not only correctly identified people, but also provided links to all publications and sources in Arcanum’s privately owned database where found faces are present. For example, the following screenshot shows the result of the famous composer and pianist Franz Liszt.

The application provided 42 pages of 6×4 results. The results are capped to 1,000. The 100% scores are the confidence scores returned by Amazon Rekognition and are rounded up to whole numbers.

The application of Hungaricana has always promptly, and with a high degree of certainty, presented results and links to all corresponding publications.

Business results

By introducing Amazon Rekognition into their workflow, Arcanum enabled a better customer experience, including building family trees, searching for historical figures, and researching historical places and events.

The concept of face searching using artificial intelligence certainly isn’t new. But Hungaricana uses it in a very creative, unique way.

Amazon Rekognition allowed Arcanum to realize three distinct advantages:

  • Time savings – The time to market speed increased dramatically. Now, instead of spending several months of intense manual labor to label all the images, the company can do this job in a few days. Before, basic labeling on 150,000 images took months for three people to complete.
  • Cost savings – Arcanum saved around $15,000 on the Hungaricana project. Before using Amazon Rekognition, there was no automation, so a human workforce had to scan all the images. Now, employees can shift their focus to other high-value tasks.
  • Improved accuracy – Users now have a much better experience regarding hit rates. Since Arcanum started using Amazon Rekognition, the number of hits has doubled. Before, out of 500,000 images, about 200,000 weren’t searchable. But with Amazon Rekognition, search is now possible for all 500,000 images.

 “Amazon Rekognition made Hungarian culture, history, and heritage more accessible to the world,” says Előd Biszak, Arcanum CEO. “It has made research a lot easier for customers building family trees, searching for historical figures, and researching historical places and events. We cannot wait to see what the future of artificial intelligence has to offer to enrich our content further.”

Conclusion

In this post, you learned how to add highly scalable face and image analysis to an enterprise-level image gallery to improve label accuracy, reduce costs, and save time.
