Patent abstract
A homomorphic encryption scheme, such as Paillier encryption in combination with a bit packing process allows biometric matching at a terminal without exposing a biometric template stored at a user's device. Because such encryption schemes are data intensive, the bit packing process allows reductions in data being sent and processed so that the biometric matching process can be accomplished in near real time. The high speed of this optimized process allows the technique to be applied to many real world processes such as access control and transaction processing.
