Modification based information hiding method affected visual quality o f the embedded carrier and always leaves modification traces.Texture constructi on based information hiding always produces non-natural textures.Texture synth e sis hiding generated texture blocks by a sample image and then stitched these bl ocks together by image quilting.However,it inevitably produces stitching trace s and repetition texture patterns to reveal the hidden secret information.To so lve these problems,generating information hiding through pixel-by-pixel textu re synthesis was proposed.In embedding,secret information was firstly coded into coordinates of a key image to avoid the direct channel transmission of secret i nformation.Secondly,these coordinates were further transformed into a high-fr e quency color sequence with multiple backups in the given sample image and then p laced randomly into a blank stego texture image to be synthesized.Finally,acco rding to pixel-by-pixel texture generation strategy to produce the synthesized s tego texture image.In extraction,the high-frequency color sequence was extrac t ed firstly according to the user key,and then coordinates of the key image were recovered to fetch the secret information combined with strategy of multiple ba ckups and interval extension.Theory and experiment show that the proposed metho d does not leave any evident stitching trace and the repetition patterns by pixe l-by-pixel texture synthesis.The secret information is utterly dependent on t he user key.It has some anti-attack abilities and has high security.
