On a Watermarking Method using a Reed-Solomon Block Turbo Decoding Algorithm

Abstract (in Japanese) (See Japanese page) 
(in English) Digital watermarking methods were proposed for copyright protection. However, tolerance to alteration and media processing is relatively low. Then, digital watermarking methods using error correcting codes were pro-
posed. In this paper, we propose a digital watermarking method of images using an error correcting code. In the proposed method, a message matrix is encoded by a Reed-Solomon product code and block turbo decoding using
an iterative erasure-and-error correction decoding is applied to a received matrix obtained from an attacked image.
We present computer simulation results of the proposed method and show its e ectiveness.
