In this paper, the authors highlight needs to solve security problem in their network society. As the important implementation of biometric technology; palmprint verification is one of the most reliable personal identification methods which is most useful technique in forensic science. Palm print are potentially a good choice for biometric application because they are invariant with a person, easy to capture and difficult to duplicate. They have greater security than fingerprint because palm veins are more complex than finger veins. This paper introduces hiding technique to address the vulnerabilities of a palmprint recognition system against attacks.
