Fingerprint verification system involving smart card

The fingerprint has been used as biometrics for user identification and authentication because of its characteristics Re uniqueness in that no two fingerprints pair from different fingers is definitely identical and its permanence. Traditional computer-aided fingerprint identification or verification system has been involving the central database of fingerprints. However, retaining the central database can cause critical fingerprint leakage. Therefore, it has been proposed to decentralize the fingerprint into each storage device such as a smart card. Also, to gain maximum security in the system, the computation of the fingerprint verification as well as the store of the fingerprint has to be taken place in the smart card in order to keep fingerprint from being streamed into the outside of the card. We call the system with this mechanism Match-on-Card system. In this paper, we introduce Match-on-Card system and explain the fingerprint verification algorithm using a multi-resolution accumulator array that can be executed in such a restricted environment as a smart card.
