Uncompromised and documented security



Ensuring security and accuracy in critical biometric applications cannot be compromised.

Typically, applications like government ID and financial inclusion payments, where security is essential, require less than one false acceptance for every 100,000 fingerprint sensor readings. For these types of uses, actual False Acceptance Rates (FARs) must be documented in credible, real life, mass market testing regimes in order to ensure confidence in a given technology. In India’s Aadhaar program for example, testing of both security and convenience levels is conducted in tests run by the government involving more than 5,000 people in harsh environment Class 3 tests, which go beyond capturing general fingerprint features to identify sweat pore-based features in the finger and achieve another layer of distinctiveness and security. The Aadhaar program is the world’s largest biometric ID system, with more than 1.2 billion people now enrolled.

In biometrics, the level of security and level of convenience are opposite forces. A reduced level of security will provide a higher level of convenience (ie. easier enrollment of fingerprint data, less data required to gain a positive match, etc). Changing system parameters to decrease the False Acceptance Rate (FAR) will consequently increase the False Rejection Rate (FRR). This means, balancing both high levels of security with high levels of convenience can only be done with a large sensor.



NEXT’s large-area fingerprint sensors allow both high levels of security and convenience to be achieved. The company’s Active Thermal™ technology provides a sensor that captures more features and more data using a manufacturing process that keeps the cost of manufacturing low. It also allows for accurate readings across a broad range of environmental conditions making enrollment and everyday use easier and more convenient.

With the ability to capture more data, more easily, NEXT helps defy the status quo in biometrics to deliver both security and convenience.
