要約(日本語): This paper presents a new approach utilizing the sensor's pattern noise and linear prediction synthesis filter　for steganography. The pattern noise is extracted from the images using wavelet-based　denoising filter. Then the approach introduces the linear　prediction synthesis filter, whose parameters are derived from the extracted noise.　After being filtered by such a filter, the secret message can be embedded by adapting the　characteristics of the sensor's pattern noise. As a result, the embedding process violate little of the natural image statistics, and hence the detectability of steganalytic method is noticeably decreased. The experimental results prove the effectiveness of the new　approach.
