In the watermark based on KL transform, a receiver can extract watermark information only using the received image. Therefore, the application to pursuit of the contents image which circulates a network will be expected On the other hand, there is a problem of diversion of the extracted watermark. In this paper, we propose on decoding of a watermark impossible to such a subject By this proposed method, both the encryption watermark and the structural change through multimedia communication channel are used. By embedding by the bw dumping factor for embedding, it becomes impossible distinguishing the watermark information extracted except the set-up threshold. This proposed method can solve an above-mentioned problem, holding the feature of decoding public algorithm which KL-type watermark has.
