CDMA Based Reversible and Blind Watermarking Scheme for Images

Muhammad Kashif Samee and Jürgen Götze

Abstract—Digital watermarking is a well known technique used for copy rights protection of multimedia data. The biggest disadvantage of general watermarking schemes is that they permanently distort original data. Reversible watermarking techniques allow the restoration of original data, after watermark detection. A blind robust and reversible watermarking algorithm based on CDMA is proposed in this paper. Watermark is arithmetically added in CDMA based watermarking schemes. Therefore, it is not difficult to make CDMA based watermarking schemes reversible. In proposed algorithm, spreaded watermark is added to middle frequency coefficients in DCT domain in a specific way. Watermark is extracted by using spreading codes only. After extraction, the watermark can be removed from watermarked data only by using same spreading codes. Furthermore, the original watermark is not required during watermark removal process.

Index Terms—Reversible watermarking, DCT, CDMA
