Abstract
A Flash-interfaced Fingerprint Sensor is disclosed. The sensor device interfaces directly with a flash memory interface chip. The flash memory interface chip incorporates the system for interfacing with flash memory devices, a fingerprint sensor/detector system, and an encryption subsystem for encrypting data being passed to and from the flash memory devices and the host computing device. The device further employs an advanced encryption approach that entails fingerprint decryption and verification on the host computer rather than on the portable memory apparatus. Once verification at the host computer is complete, memory and host functionality is enabled.
