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.
