SA-4 Identification Solutions for Access Control
Cogent’s SA-4 SecurASIC OEM Module is an image processing and matching unit designed specifically for OEM devices requiring highly secure biometric authentication and identification. Powered by Cogent’s proprietary SecurASIC microprocessor, the SA-4 also features Cogent’s two-dimensional D2SP engine and an ARM940 32-bit microprocessor core – both on a single ASIC chip.

The SA-4 OEM Module is equipped with a 500-DPI silicon fingerprint sensor and two RS232 ports. These ports can be used to communicate with the PC host or can be connected to magnetic stripe, contact or contactless smart card readers. The SA-4 also has built in commands to facilitate the integration of biometric components into existing or new products.

The SA-4 offers both 1:1 authentication and 1:N identification algorithms with the same template. The SA-4 also supports a Cogent’s proprietary algorithm, as well as ANSI-378 and PIV supported decoder / matcher. Application host systems can manage the OEM module using our standard communication protocol. To achieve maximum security, the module provides an optional 3DES encryption and decryption algorithm for data transmission between the module and host PC. Additionally, the SA-4 provides support for standalone and match-on card applications.
