A Proposed Method for Image Steganography using Edge Detection

In this paper, we proposed a technique to hide the text data into the color images using edge detection method. The alteration in edges cannot be distinguished well so edges can hide more data without losing quality of an image. In this technique, Edges of an image are detected by scanning using 3x3 window and then text message is concealed in edges using first component alteration technique. The proposed scheme achieved high embedding capacity and high quality of encoded image.
