Image steganography has received a lot of attention during the last decade due to the lowering of the cost of storage media, which has allowed for wide use of a large number of images. We present a novel technique for image steganography which belongs to techniques taking advantage of sharp areas in images in order to hide a large amount of data. Specifically, the technique is based on the edges present in an image. A hybrid edge detector is used for this purpose. Moreover, a high payload technique for color images is exploited. These two techniques are combined in order to produce a new steganographic algorithm. Experimental results show that the new method achieves a higher peak signal to noise ratio for the same number of bits per pixel of embedded image.
