DIGITAL WATERMARKING CAN BE USED TO PROTECT AND TRACK COPYRIGHT OF DIGITAL IMAGES IN E-COMMERCE
In current E-Commerce,digital images can be easily copied and redistributed through the Internet. Its hard for digital images authors and customers to protect their rights and interests. In this paper, authors proposed a copyright protectlan and tracing algorithm by using M levels wavelet transform on the YIQ color space of original digital image. According to the principle of wavelet zero-tree, authors copyright information is embedded in HL subband as watermarking, and the license of customers is embedded in LH subband as watermarking. With the robustness of the watermarking and fafty of encryption algorithm,the legal rights of the author and the customer are protected.
