Abstract
Through analysing self-embedded procedure and human vision characteristics, this paper presents an algorithm of image selfembedding and self-restoring.The algorithm compresses original image data to produce sub-block codes, selects appropriate carrier blocks and builds one-to-one correspondence between the sub-block codes and the carrier blocks; it forms image authentication information using hash function, and embeds sub-block codes, location information and authentication information into low bytes of the image itself.Experiments show that the invisibility of secret information is satisfied, and the algorithm can effectively authenticate the integrity of damaged image and restores the content of the damaged part.The restored image has very good vision effect, the image content can be well recognized.关键词
