Steganography is method used for hiding information in secure manner. Advantage of Steganography over cryptography is that intended secret message does not attract attention to itself as an object of scrutiny. In this paper we proposed a new image steganographic technique that embeds secret image only in the fringe regions of the cover image while keeping the smoother regions intact. This technique of data hiding gives more security[1]. This is due to human visual system (HVS) that can tolerate some degree of changes in the fringes whereas it is sensitive to slight changes in smooth areas. Fringe of the cover image are calculated via Canny Edge Detection algorithm. Embedding is applied only in randomly selected fringe pixels rather than all fringes [2]. For embedding purpose, an indicator channel is selected from RGB channel. Secret data bits are embedded to variable no of LSB of other two channels. Indicator is selected as maximum intensity color channel to provide the information about data bits whether they are inserted into that pixel or not.
