I construct hash fucntion
SHA base on" Authentication Methods: From Digital Signatures to
Hashes" at
www.winlab.rutgers.edu/~trappe/ Courses/AdvSec05/AuthentMethods.ppt
but when I apply this algorithm to a original frame and
watermarked frame then values of hash fuction in two cases are equal. Five next days I have to submit my project so I need your help
very.
Thanks for advance.
