Color image watermarking robust to JPEG compression

Abstract EN

Digital Watermarking has emerged as a new area of research in an attempt to prevent illegal copying and duplication and false representation.

In this paper, a proposed algorithm for digital watermarking for color images was presented.

This algorithm make use of the linearity for DCT transform and introduce a watermarking that is robust against JPEG compression, in this algorithm, the linearity of the Discrete Cosine Transform is used which approve a robust watermarking algorithm against JPEG compression for high compression ratios till 1% image quality.
