for biometrics including watermark embedding technique and fixed digit
encryption. A biometric authentication system is vulnerable to a mixture
of attacks. These attacks are anticipated to either evade the security
afforded by the system or to discourage the usual functioning of the system.
Here, we briefly review some of the known attacks that can be encountered
by a biometric system and some corresponding protection techniques. We
explicitly focus on threats designed to extract information about the
original biometric data of an individual from the stored data as well
as the entire authentication system. We offer a biometric authentication
scheme which uses two separate biometric features combined by watermark
embedding with fixed digit encryption to obtain a non-unique identifier
of the individual, in order to address security and privacy concerns.
Moreover, we provide experimental results presenting the performance of
the authentication system. In the client-server environment the transformed
features and templates travel through insecure communication line like
the internet or intranet. Our proposed technique causes security against
eavesdropping and replay attacks on the internet or intranet, because
the transmitted feature information and the templates are different every
time.]]>Huang, D.S., W. Jia and D. Zhang,20084113161328Jain, K., A. Ross and U. Uludag,20052005pp: 14Maltoni, D., D. Maio, A.K. Jain and S.
