As portable media proliferates into more and more consumer products, data security is becoming increasingly important. New products need to be secure in order to protect confidential information from theft.  Biometric security offers an economical solution that doesn't add significant user burdens such as extra passwords or additional log-in steps. Biometric security methods include fingerprint sensing, retina and iris scanning, signature analysis and hand geometry. Consider the case of fingerprint sensing. With a simple swipe of a finger, a user can authenticate himself to gain access to data on a portable storage device.  This article will provide a simple, step by step design sequence to add fingerprint security to a USB mass storage device.
