Abstract (in Japanese) (See Japanese page) 
(in English) Data embedding to printed images has become an important issue for several applications. The data retrieval techniques from the data embedded printed images have classified into two classes, i.e. a mobile terminal based method and a server based method. In this paper, we assume an original image to be known and the server based method, and a new method for the data embedding to the printed images is proposed. To increase the number of the embedding data bits in the processing of embedding, we adopt “Walsh code” for diffusion code, which is strong to the interference between diffusion codes. As a result, many number of the data bits can be embedded. This can be also applied to the improvement of the detection process and we propose the embedding of same data to three blocks. This technique gives the tolerance to some distortion and noises. In the detection processing, a taken image is forwarded to the server which holds the original image and the embedded data is detected in the server. As a result, more accurate detection can become possible. Finally, the simulation results of the proposed technique show that it can embed many number of the data bits and obtain the high detection rate of the embedding bits.
