摘要：The fundamental objectives of image steganography algorithm are to simultaneously achieve high payload or embedding capacity, good visual imperceptibility and security. This paper presents a new approach to improve the embedding capacity and provide an imperceptible visual quality, a novel steganography method based on algorithm twenty five pixel value differencing and modified interval table (TFPVD). The cover image is made into 5×5 blocks that don’t overlap and TFPVD method with modified interval is used to embed and extract secret information. The results showed that the proposed TFPVD steganography algorithm has a higher steganographic capacity, which is 1,764 times that of the PBVD algorithm.
