Biometric SyStemS
e development of biometric technologies aims to implement a
method ensuring a high level of security. is chapter presents
general biometric systems for data security and authentication
of persons. A study of various biometric techniques is detailed.
en, a comparative study between these different techniques
is established to specify which method is desirable. is com-
parative study shows that the method of biometric authentica-
tion based on the iris of the eye is most suitable for our research
project. is justifies the presentation of the various algorithms
for the recognition of the iris of the eye by stating, at each phase
of the algorithm, the methods adopted. e aspects of discrete
geometry for the definition of an ...
