Multi-Edge Concept used for Image Steganography

Resumen

Digital Steganography means hiding sensitive data inside a cover object in a way that is invisible to un-authorized persons. Many proposed steganography techniques in spatial domain may achieve high invisibility requirement but sacrifice the good robustness against attacks. In some cases, we need to take in account not just the invisibility but also we need to think about other requirement which is the robustness of recovering the embedded secrete messages.  In this paper we propose a new steganoraphic scheme that aims to achieve the robustness even the stego image attacked by steganalyzers. Furthermore, we proposed a scheme which is more robust against JPEG compression attack compared with other traditional steganography schemes.
