| Research Abstract |
We developed information hiding technologies using complete complementary codes, one of the spread spectrum sequences with ideal correlation properties. Specifically, a digital watermarking scheme, a digital fingerprinting scheme, and a steganography scheme using image data are proposed. The properties of these schemes are evaluated through numerical experiments on the transparency of the secret information, correctness of the extraction and the robustness against various attacks. As a result, it is shown that the proposed schemes have superior to the method based on other spread sequences.
