Image Steganography algorithm based on edge detection

A novel steganography algorithm is proposed based on local reference edge detection technique and exclusive disjunction (XOR) property is proposed. Human eyes are less sensitive towards intensity changes in the sharp edge region compared to the uniform region of the image. Because of this, the secret message bits have been embedded in the sharp regions by local reference pixels that are located in the edge blocks. The predefined sets of pixels are easily identified with less computational complexity in the stego image. The embedding algorithm improved in terms of security…
