Hardware/Software Codesign for an Iris Biometric Search Engine

Many airports are employing Biometric Technology to check the user identity nowadays. Till nowadays, the use of Biometric in this situation is restricted to verification, i.e., the user at the same time he/she provides his/her Biometric data, provides also his/her identity. However, in some cases, it is needed to search among all users stored in the database for the identity of the user. For this purpose, search engines are used. In this paper, authors propose an architecture for a Biometric search engine. The architecture proposal performs part of the algorithm using dedicated hardware and dataflow control is done by a microprocessor, obtaining with this configuration high speed and reliability.
