Abstract

A multiple watermarking algorithm based on the CDMA spread spectrum technique is presented. Multiple copyright Identifiers are convolutional encoded and block interleaved, and the orthogonal Gold sequences are used to spread spectrum of the copyright messages. The CDMA encoded copyright messages are embedded into the original image with the help of discrete wavelet transformation.
