What Makes the Latest Version of TrulySecure so Different?

May 17, 2017

A key measure of any biometric system is the inherent accuracy of the matching algorithm. Earlier attempts at face recognition were based on traditional computer vision (CV) techniques. The first attempts involved measuring key distances on the face and comparing those across images, from which the idea of the number of “facial features” associated with an algorithm was born. This method turned out to be very brittle however, especially as the pose angle or expression varied. The next class of algorithms involved parsing the face into a grid, and analyzing each section of the grid individually via standard CV techniques, such as frequency analysis, wavelet transforms, local binary patterns (LBP), etc. Up until recently, these constituted the state of the art in face recognition. Voice recognition has a similar history in the use of traditional signal processing techniques.

Sensory’s TrulySecure uses a deep learning approach in our face and voice recognition algorithms. Deep learning (a subset of machine learning) is a modern variant of artificial neural networks, which Sensory has been using since the very beginning in 1994, and thus we have extensive experience in this area. In just the last few years, deep learning has become the primary technology for many CV applications, and especially face recognition. There have been recent announcements in the news by Google, Facebook, and others on face recognition systems they have developed that outperform humans. This is based on analyzing a data set such as Labeled Faces in the Wild, which has images captured over a very wide ranging set of conditions, especially larger angles and distances from the face. We’ve trained our network for the authentication case, which has a more limited range of conditions, using our large data set collected via AppLock and other methods. This allows us to perform better than those algorithms would do for this application, while also keeping our size and processing power requirements under control (the Google and Facebook deep learning implementations are run on arrays of servers).

One consequence of the deep learning approach is that we don’t use a number of points on the face per se. The salient features of a face are compressed down to a set of coefficients, but they do not directly correspond to physical locations or measurements of the face. Rather these “features” are discovered by the algorithm during the training phase – the model is optimized to reduce face images to a set of coefficients that efficiently separate faces of a particular individual from faces of all others. This is a much more robust way of assessing the face than the traditional methods, and that is why we decided to utilize deep learning opposed to CV algorithms for face recognition.

Sensory has also developed a great deal of expertise in making these deep learning approaches work in limited memory or processing power environments (e.g., mobile devices). This combination creates a significant barrier for any competitor to try to switch to a deep learning paradigm. Optimizing neural networks for constrained environments has been part of Sensory’s DNA since the very beginning.

One of the most critical elements to creating a successful deep learning based algorithm such as the ones used in TrulySecure is the availability of a large and realistic data set. Sensory has been amassing data from a wide array of real world conditions and devices for the past several years, which has made it possible to train and independently test the TrulySecure system to a high statistical significance, even at extremely low FARs.

It is important to understand how Sensory’s TrulySecure fuses the face and voice biometrics when both are available. We implement two different combination strategies in our technology. In both cases, we compute a combined score that fuses face and voice information (when both are present). Convenience mode allows the use of either face or voice or the combined score to authenticate. TrulySecure mode requires both face and voice to match individually.

More specifically, Convenience mode checks for one of face, voice, or the combined score to pass the current security level setting. It assumes a willingness by the user to present both biometrics if necessary to achieve authentication, though in most cases, they will only need to present one. For example, when face alone does not succeed, the user would then try saying the passphrase. In this mode the system is extremely robust to environmental conditions, such as relying on voice instead of face when the lighting is very low. TrulySecure mode, on the other hand, requires that both face and voice meet a minimum match requirement, and that the combined score passes the current security level setting.

TrulySecure utilizes adaptive enrollment to improve FRR with virtually no change in FAR. Sensory’s Adaptive Enrollment technology can quickly enhance a user profile from the initial single enrollment and dramatically improve the detection rate, and is able to do this seamlessly during normal use. Adaptive enrollment can produce a rapid reduction in the false rejection rate. In testing, after just 2 adaptations, we have seen almost a 40% reduction in FRR. After 6 failed authentication attempts, we see more than 60% reduction. This improvement in FRR comes with virtually no change in FAR. Additionally, adaptive enrollment alleviates the false rejects associated with users wearing sunglasses, hats, or trying to authenticate in low-light, during rapid motion, challenging angles, with changing expressions and changing facial hair.

TrulySecure 2.0 Wins First Place in 2016 CTIA E-Tech Awards

September 9, 2016

Print

We are pleased to announce that Sensory’s TrulySecure technology has earned first place in this year’s CTIA E-Tech Awards. We believe that this recognition serves as a testament to Sensory’s devotion to developing the best embedded speech recognition and biometric security technologies available.

For those of you unfamiliar with TrulySecure – TrulySecure is the result of more than 20 years of Sensory’s industry leading and award-winning experience in the biometric space. The TrulySecure SDK allows application developers concerned about both security and convenience to quickly and easily deploy a multimodal voice and vision authentication solution for mobile phones, tablets, and PCs. TrulySecure is highly secure, environment robust, and user friendly – offering better protection and greater convenience than passwords, PINs, fingerprint readers and other biometric scanners. TrulySecure offers the industry’s best accuracy at recognizing the right user, while keeping unauthorized users out. Sensory’s advanced deep learning neural networks are fine tuned to provide verified users with instant access to protected apps and services, without the all too common false rejections of the right user associated with other biometric authentication methods. TrulySecure features a quick and easy enrollment process – capturing voice and face simultaneously in a few seconds. Authentication is on-device and almost instantaneous.

TrulySecure provides maximum security against unauthorized attempts by mobile identity thieves from breaking into a protected mobile device, while ensuring the most accurate verification rates for the actual user. Compared to published data by Apple, the iPhone’s thumbprint reader offers about in 1:50K chance of a false accept of the wrong user, and the probability of the wrong user getting into the device gets higher when the user enrolls more than one finger. With TrulySecure, face and voice biometrics individually offer a baseline 1:50k false accept rate, but can each be made more secure depending on the security needs of the developer. When both face and voice biometrics are required for user authentication, TrulySecure is virtually impenetrable by anybody but the actual user. As a baseline, TrulySecure’s face+voice authentication offers a baseline of 1:100k False Accept Rate, but can be dialed in to offer as much as a 1:1Million False Accept Rate depending on security needs.

TrulySecure is robust to environmental challenges such as low light or high noise – it works in real-life situations that render lesser offerings useless. The proprietary speaker verification, face recognition, and biometric fusion algorithms leverage Sensory’s deep strength in speech processing, computer vision, and machine learning to continually make the user experience faster, more accurate, and more secure. The more the user uses TrulySecure, the more secure it gets.

TrulySecure offers ease-of-mind specifications: no special hardware is required – the solution uses standard microphones and cameras universally installed on today’s phones, tablets and PCs. All processing and encryption is done on-device, so personal data remains secure – no personally identifiable data is sent to the cloud. TrulySecure was also the first biometric fusion technology to be FIDO UAF Certified.

While we are truly honored to be the recipient of this prestigious award, we won’t rest on our laurels. Our engineers are already working on the next generation of TrulySecure, further improving accuracy and security, as well as refining the already excellent user experience.

IoT Roadshow with Open Systems Media

May 6, 2016

Rich Nass and Barbara Quinlan from Open Systems Media visited Sensory on their “IoT Roadshow”.

IoT is a very interesting area. About 10 years ago we saw voice controlled IoT on the way, and we started calling the market SCIDs – Speech Controlled Internet Devices. I like IoT better, it’s certainly a more popular name for the segment! ;-)

I started our meeting off by talking about Sensory’s three products – TrulyHandsfree Voice Control, TrulySecure Authentication, and TrulyNatural large vocabulary embedded speech recognition.

Although TrulyHandsfree is best known for its “always on” capabilities, ideal for listening for key phrases (like OK Google, Hey Cortana, and Alexa), it can be used a ton of other ways. One of them is for hands-free photo taking, so no selfie stick is required. To demonstrate, I put my camera on the table and took pictures of Barbara and Rich.  (Normally I might have joined the pictures, but their healthy hair, naturally good looks, and formal attire was too outclassing for my participation).

There’s a lot of hype about IoT and Wearables and I’m a big believer in both. That said, I think Amazon’s Echo is the perfect example of a revolutionary product that showcases the use of speech recognition in the IoT space and am looking forward to some innovative uses of speech in Wearables!

Here’s the article they wrote on their visit to Sensory and an impromptu video showing TrulyNatural performing on-device navigation, as well as a demo of TrulySecure via our AppLock Face/Voice Recognition app.

IoT Roadshow, Santa Clara – Sensory: Look ma, no hands!

Rich Nass, Embedded Computing Brand Director

If you’re an IoT device that requires hands-free operation, check out Sensory, just like I did while I was OpenSystems Media’s IoT Roadshow. Sensory’s technology worked flawlessly running through the demo, as you can see in the video. We ran through two different products, one for input and one for security.

Face and Voice Biometrics Quickly Gaining Popularity

February 22, 2016

Recently Peter O’Niel at FindBiometrics interviewed our CEO Todd Mozer about Sensory’s recent announcement of TrulySecure 2.0, check out the interview here: FindBiometrics

Summary: The industry is embracing biometrics faster than ever and many CE companies and app developers are embracing face and voice biometrics to improve user experience and bolster security. Face and voice offers significant advantages over other biometric modalities, notably when it comes to convenience, and particularly in the case of our TrulySecure technology, accuracy and security.

Sensory’s TrulySecure technology has evolved dramatically since its release and recently we announced TrulySecure 2.0 that actually utilizes real world usage data collected from our “AppLock by Sensory” app on the Google Play store. By applying what we learned with AppLock, we were able to adapt a deep learning approach using convolutional neural networks to improve the accuracy of our face authentication. Additionally, we significantly improved the performance of our speaker verification in real world conditions by training better neural nets based on the collected data.

Overall, we have been able to update TrulySecure’s already excellent performance to be even better! The solution is now faster, smarter and more secure, and is the most accurate face and voice biometrics solution available.

Google Play Statistics Shows Ease of Use Correlates to Biometric Ratings

December 8, 2015

I saw an interesting press release titled “EyeVerify Gets Positive Feedback From Curious Users”. I know this company as a fellow biometrics vendor selling into some of the same markets as Sensory. I also knew that their Google Playstore rating hovered around a 3/5 rating while our AppLock app hits around a 4/5 rating, so I was curious about what this announcement meant. It made me think of the power of all the data in the Google Playstore, and I decided to take a look at biometric ratings in general to see if there were any interesting conclusions.

Here’s my methodology…I conducted searches for applications in Google Play that use biometrics to lock applications or other things. I wanted the primary review to relate to the biometric itself, so I excluded “pranks” and other apps that provided something other than biometric security.  I also rejected apps with less than 5,000 downloads to insure that friends, employees and families weren’t having a substantive effect on the ratings. I ran a variety of searches for four key biometrics: Eyes, Face, Fingerprint and Voice.

I did not attempt to exhaust the entire list of biometric apps, I searched under a variety of terms until I had millions of downloads for each category with a minimum of 25,000 reviews for each category. The “eye” was the only biometric category that couldn’t meet this criteria, as I had to be satisfied with 6,884 reviews. Here’s a summary chart of my findings:

Capturebig

As you can see, this shows the total number of downloads, the total number of apps/companies, the number of reviews and the avg rating of reviews per biometric category. So, for example, Face had 11 applications with 1.75 million total downloads and just over 25,000 reviews with an average review rating of 3.89.

What’s most interesting to me about the findings is that it points to HIGHER RATINGS FOR EASIER TO USE BIOMETRICS. This is a direct correlation as Face comes in first and is clearly the easiest biometric to use Voice is somewhat more intrusive as a user must speak, and the rating drops by .16 to 3.73, though this segment does seem to receive the most consumer interest with more than 5-million downloads. Finger is today’s most common biometric but is often criticized by its 2-hand requirement and that it often fails, requiring users to re-swipe, consumer satisfaction with fingerprint is about 3.67. Eye came in last, albeit with the least data, but numbers don’t lie, and the average consumer rating for that biometric comes in at about 3.42. If you consider the large number of reviews in this study and the narrow range of review scores (which typically range from 2.5 to 4.5), the statistically significant nature becomes apparent.

The results were not really a surprise to me. When we first developed TrulySecure, it was based on the premise that users wanted a more convenient biometric without sacrificing security, so we focused on COMBINING the two most convenient biometrics (face and voice) to produce a combined security that could match the most stringent of requirements.

 

Banks Looking to Biometrics for Improved Customer Security

October 16, 2015

I saw a LinkedIn message to one of the biometrics groups in which I’m a member linking to a new video on biometrics:

I was quite surprised to see that I am actually in it!

It’s a great topic…Banks turning to biometrics. The video doesn’t talk too much about what’s really happening and why, so I’ll blog about a few salient points, worthy of understanding:

1)    Passwords are on their deathbed. This is old news and everyone gets it, but worthy of repeating. Too easy to crack and/or too hard to remember

2)    Mobile is everything, and mobile biometrics will be the entry point. Our mobile phones will be the tools to control and open a variety of things. Our phones will know who we are and keep track of the probability of that changing as we use them. Mobile banking apps will be accessed through biometrics and that will allow us to not only check balances, but pay or send money or speed ATM transactions.

3)    EMV credit cards are here…Biometric credit confirmation is next! Did you get a smart card from your bank? Europay, Visa, and MasterCard decided to improve fraud by shifting fraud risk based on security implemented. Smart cards are now, biometrics will be added to aid fraud prevention.

4)    It’s all about convenience & security. So much focus has been on security that convenience was often overlooked. There was a perception that you can’t have both! With Biometrics you actually can have an extremely fast and convenient solution that is highly accurate.

5)    Layered biometrics will rule. Any one biometric or authentication approach in isolation will fail. The key is to layer a variety of authentication techniques that enhance the systems security but don’t hurt convenience. Voice and face authentication can be used together, passwords can be thrown on top if the biometric confirmation is unsure, tokens or fingerprint or iris scans can also be deployed if the security isn’t high enough. The key is knowing the accuracy of match and increasing the security to the desired security level in a stepped function so as to maximize user convenience.

TrulySecure From Sensory Becomes First Face and Voice Biometrics Technology to be FIDO UAF Certified

August 20, 2015

Santa Clara, Calif., – August 20, 2015 – TrulySecure Multimodal Biometric Authentication from Sensory, Inc. Has Been Fully Tested and Certified for Compliance with the FIDO Universal Authentication Framework Specifications V1.0

Sensory Inc., a Silicon Valley based company focused on improving the user experience and security of consumer electronics through state-of-the-art embedded voice and vision technologies, today announced that its TrulySecure™ is the first multimodal face and voice biometric authentication software to be FIDO Certified™. The FIDO (Fast Identification Online) Alliance tested TrulySecure for compliance with the FIDO UAF (Universal Authentication Framework) 1.0 specifications, which determines that implementations of the FIDO specification are uniform across products and that those products are interoperable with other products and services that support the FIDO 1.0 specifications.

“We recognize Sensory for building TrulySecure to be fully compliant with the FIDO Universal Authentication Framework specifications and are excited to add their innovative multimodal biometric authentication solution to the FIDO Alliance’s prestigious roster of FIDO UAF Certified authenticators,” said Brett McDowell, FIDO Alliance executive director. “As more enterprises, application developers and mobile device makers shift away from password authentication, solutions like Sensory’s TrulySecure multimodal biometric authentication software will continue to prove valuable as an essential, secure means of authenticating users and keeping their data safeguarded.”

Working with the FIDO Alliance to certify compliance with FIDO standards and interoperability of TrulySecure demonstrates Sensory’s commitment to advancing the current state of user authentication, by ensuring that the industry’s most secure multimodal face and voice authentication software can be easily integrated within authentication solutions from FIDO Certified™ providers. Sensory joined the FIDO Alliance in early 2015 to work alongside other companies eager to create more secure user authentication protocols. Sensory has been a strong supporter of the FIDO Alliance since its inception and has worked with companies like Nok Nok Labs to ensure the biometric authenticator portion of their authentication solution, powered by TrulySecure from Sensory, was fully compliant with FIDO UAF 1.0 specs.

“Sensory’s TrulySecure is a great example of what can be delivered with multimodal biometrics and we are happy to support the solution within our own FIDO Certified S3 Authentication Suite,” said Ramesh Kesanupalli, founder of Nok Nok Labs and FIDO visionary. “Enterprises are looking for turnkey user solutions that offer a mix of authentication methods. Working with Sensory allows Nok Nok Labs to provide its customers with a greater variety of solutions that offer superior security compared to vulnerable passwords.”

TrulySecure leverages Sensory’s deep strengths in speech processing, computer vision, and machine learning. The combination of face recognition and speaker verification to authenticate a specific individual allows users to rest assured that their device is secure, without the hassle of fumbling around with a fingerprint reader or entering a password or PIN every time they want to access it or authenticate to sites and services. Consistent with FIDO standards, TrulySecure is an on-device biometric not requiring a cloud connection. Embedded authentication is a preferred approach for consumers and businesses that don’t want their biometric information stored outside of their personal devices. Embedded biometric solutions are also preferred for their higher security and reliability compared to cloud based systems, which have proven to be vulnerable to hackers and break-ins, and undependable in low-signal/no Internet environments. In addition to the security and dependability benefits of being embedded, TrulySecure further safeguards devices and data by requiring two forms of biometrics, making it at least twice as secure as even the best fingerprint readers found on mobile devices.

The advantages of TrulySecure when compared to other biometric authentication methods include:

  • Simple touch-free authentication – users do not need to tap a screen or swipe a finger, just look at the screen and say the passphrase
  • Its fast! – embedded within software or on device, TrulyHandsfree does not require an Internet or cloud connection to work and responds instantly
  • Robust to environmental changes – works in real-world situations, including low light or high noise environments
  • Nearly impenetrable by imposters – unlike fingerprint readers, which are vulnerable to spoofing, TrulySecure features anti-spoofing techniques to eliminate the chances of an intruder getting access
  • No additional hardware costs – TrulySecure only requires a device have a microphone and a camera; nearly all smartphones, tablets and PCs already feature these components
  • No hardware to wear out – biometric sensors, such as fingerprint readers, wear out with use; since TrulyHandsfree does not rely on special sensors, there is no risk of authentication hardware failure

“We at Sensory are huge supporters of the work the FIDO Alliance has done to create an exciting consortium focused on streamlining user transactions with on-device biometrics,” said Todd Mozer, chairman and CEO of Sensory, Inc. “Promoting biometrics for more than two decades, we are pleased that our TrulySecure technology has become the first multimodal face and vision biometrics technology to be awarded the status of FIDO Certified. By working with companies across the entire authentication ecosystem to certify the interoperability of their FIDO Certified technologies with TrulySecure, we have made it even easier for companies to integrate the industry’s easiest to use and most secure biometric authentication technology within their products.”
