AN EFFICIENT HASH BASED STEGANOGRAPHY TECHNIQUE FOR TEXT MESSAGE USING COLOR IMAGES
Saurabh Singh, Ashutosh Datar · 2013
In this paper, a hash based approach for color image Steganography using canny edge detection method is proposed. One of the advantages of using edge detection technique is to secure the data. For encoding the text data in an image Steganography procedure is followed. Edge detection is done by canny method and then hash function is used to embed text data in the RGB color image. The hash is a fast and secure approach for image Steganography. This found that canny edge detection offers superior performance for detecting edges in an image. Large edge detected image is preferred for secure Steganography. The proposed method provides a better security and supports different types of file format like-jpg, jpeg, bmp, tiff etc.
