In recent years, opportunities to exchange information on the Internet has increased. Under such circumstances, steganography is a technology for safely exchanging information. Previous studies have proposed some methods that combine Shamir's secret sharing method and correlation-based steganography. Correlation-based steganography embeds pseudo-random number as a secret information in DCT (discrete cosine transform) coefficient of an image and extracts the secret information by correlating the pseudo-random number and DCT coefficient. Since it is necessary to obtain a good correlation at the time of extracting, each value of the pseudorandom number sequence is increased by coefficient. This increasing of values causes image quality deterioration. In this paper, we propose a steganography with an error-correcting code. Our proposed method can improve the embedding capacity without deterioration the image quality.
