REVERSIBLE IMAGE STEGANOGRAPHY BASED ON EDGE DETECTION AND MPVD

The development of reversible image steganography techniques is of great interest to many scholars. We also presented a reversible image steganography in this study using modified pixel value differencing (MPVD) and edge detection. We gather edge and non-edge pixels from the cover image by using the edge detection technique. The amount of implanted bits into the cover pixels is then determined by dividing the difference between the edge and non-edge pixels. Using the MPVD technique, we implant secret bits in edge pixels and produce a stego image. This stego image will be delivered to the recipient. The concealed message and cover media are extracted by the recipient at their end. This approach works well for subliminal messaging. It simultaneously preserves the quality of the visuals and shields implanted data's privacy from different kinds of cyber-attacks. The experimental findings yield encouraging results.
