[WM]: Ask about SHA



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.

Thu Thuy
