In this paper, image steganography technique based on first component alteration technique using hybrid edge detector is proposed. There are lots of algorithms to hide data but they are also decreasing the quality of the image. In this work, edges of an RGB image has been detected by hybrid edge detector which is the combination of 3x3 matrix scanning and sobel edge detector, and then text will be embedded in to the first component of edges of the color image. Experimental results show that we have achieved not only high embedding capacity but also enhanced the quality of the stego image.
