Synaptics expands fingerprint authentication

Synaptics Inc. has unveiled its latest biometric authentication solution, the Triton FS7800 family of high-resolution single-chip Match-in-Sensor (MiS) fingerprint authentication sensors. The family delivers secure biometric user access to PCs and mobile devices.

The Triton family extends Synaptics’ MiS-style sensor solution offerings and specifically addresses the increased security challenges of a mobile workforce, new types of work styles and their inherent risks. The stand-alone sensors contain a processor, storage and cryptographic capabilities that perform matching in an environment isolated from the host, which delivers protection from hacking and malware that could be on the host.

The sensor works by performing biometric identification autonomously, sending an identification result to the host that is encrypted and signed using a sensor-specific key. The solution is efficient to integrate for a wide range of industrial design requirements and unobtrusive for end users to be able to easily and securely access their devices.

The single-chip solution performs authentication with an in-sensor microprocessor executing firmware. It also features an integrated internal flash memory for instructions and a fingerprint database. Hardware accelerated cryptographic features provide matching and image processing. Usable in several design configurations and when placed under different types of materials, the sensor can be implemented in different shapes and sizes to meet a variety of ID requirements, as well as be used at different locations on a PC.

Available now, the Triton FS7800 family is currently available in a 500-dpi silicon sensor with two flexible, easy-to-integrate packaging options: one for use with a glass overlay (FS7801) and one for use with a coating overlay (FS7802. Both accelerate system design and provide NIST SP 800-193-level protection to prevent unsigned firmware-level hacking. For PC applications, it is fully compliant with Microsoft Windows Hello requirements and is Enhanced Sign-in Security (ESS) capable, per the Windows 11 modern device security levels definition.
