Abstract

A new robust watermarking scheme based on triplet of wavelet coefficients is proposed. Triplets of wavelet coefficients are defined then selected and classified into two classes to embed and extract the watermark according to the relationship of their three wavelet coefficients. The shuffle algorithm is also adopted to randomize the watermark sequence for the purpose of security. Experimental results show that the degradation caused by the proposed algorithm is very slight, and this watermarking scheme is very robust to common image processing and malicious attack.
