Multipurpose Watermarking Method Based on Blind Vector Quantization

Many image watermarking methods have been proposed over the last decade; however, most of them only focus single or two purposes, verification of copyright and integrity. This paper proposed a multipurpose watermarking method based on blind vector quantization (BVQ) and there are three purposes, copyright protection, integrity verification, and distinguish between malicious and non-malicious manipulations, are achieved in this method. The codebook doesn´t need to be transmitted to receiver, but reconstructed from the received image. The effects of this method are shown in experimental results.
