| Abstract(in English) | Digital cinema is attracting attention from development of digital technology in recent years, or the spread of the Internet. However, since a duplicate can do the digitized contents simply, the duplicate of the contents which invaded copyright has been a problem, "digital watermarking" embedded as a means to protect the copyright of contents from such an illegal copy so that man cannot perceive information in contents attracts attention.Then, in this paper, the digital watermarking technique for the still picture which used wavelet transform is proposed. By this technique, if the number of times written in beforehand is decided, only the number of times can be added. Furthermore, in order to give an attestation function, the embedding position was distributed by the Hash Function, and extraction by the third person is prevented. |
