Frequency domain combination for preserving data in space specified token with high security

Abstract

A space specified token may be used in future for the purpose of authentication in all aspects. Digital information to be stored in space specified token should be of minimized size. Such minimization of the digital data is done and stored using watermarking procedure as proposed for secure purpose. For higher security the key to perform watermarking and Encoding/ Decoding is obtained from a Biometric trait as an added feature © 2011 Springer-Verlag.
