Steganography is a technique of information security that hides secret information within a normal carrier media, such as digital image, audio, video, etc. An unauthorized attempt to detect and extract the hidden secret information from stego is known as stego analysis. The important requirement for a good steganographic algorithm is that the stego media should remain identical to the original carrier media, while keeping embedding rate as high as possible. In this paper, the authors consider digital frame as carrier and develop a steganographic algorithm in spatial domain with lsb replacement based on dct coefficients of the pixels.
