Efficient Joint Watermarking and WSQ Compression Scheme

Abstract

In this paper, an efficient joint watermarking and Wavelet Scalar Quantization (WSQ) compression scheme based on Quantization Index Modulation (QIM) watermarking approach is proposed to attenuate the impact of the compression operation on the embedded watermark. The proposed scheme allows the embedding of secret message directly into the fingerprint data when compressed by the WSQ algorithm. Experimental results have shown the robustness of the proposed scheme against the WSQ compression while slightly affecting its compression performance (i.e. visual quality and compression rate).
