ABSTRACT
The proposed model described in this chapter is based on the biometric authentication method using the iris of the eye and the asymmetric cryptography using the Rivest-Shamir-Adleman (RSA) algorithm (Stallings 1999). This model is founded on the use of the biometric iris signature gabarit of a person to access a computer system. The justification for the choice of the biometric model based on the iris of the eye is presented in this chapter, as well as the description of the different modules constituting this model. In this model the authentication process allows obtaining a gabarit “diagonal horizontal vertical approximation” (DHVA)* encrypted. This will be compared with other gabarits DHVA encrypted stored in the database to verify access to the computer system. A method of classification of these gabarits is detailed in order to speed the verification process, especially for a large database.
