Recognition systems that verifies the authenticity of a
person is an important application to control access to
computer networks, airports, sensitive establishments and all
such supplications where a person’s unique feature is to be
used. Applications based on human biometrics are
increasingly being used in today’s access control systems to
control access to secured systems. The characteristic
uniqueness and stability of a human iris never gets changed
unless damaged or hurt, and hence a creditable reliable
biometric object to identify an authentic person from an
impostor.
