| Abstract | ||
| Steganography is the science of "invisible" communication. The objective of steganography is to preserve secret communication between two sides. The secret information can be hiding in content like image, audio, or video. This paper present an effective singular value decomposition (SVD) based image steganography approach with chaotic zigzag for mapping the hiding information. This approach objective, at increasing the sincerity of the image after data embedding. The algorithm is suggested in this paper that embeds secure image by small amendment of column entries in the left unique vectors, diagonal entries in the unique values and row entries in the right singular vectors of blocks of the image in like a way that the visible quality of the image is not a influenced due to embedding of the image. Experience outcome presentation the superiority of the proposed steganography approach to the existing approaches. | ||
