摘要
This paper proposes a new image steganography method of hiding multiple secret images (2 bit binary image) in a single cover image (24 bit cover image). According to the proposed method, one of the secret images is embedded in a randomized nature in one of the primary color matrix of the color cover image using the least significant bit substitution technique. The other secret images are encrypted using the first secret image. From the stego-image, the first secret image embedded randomly in the cover image is extracted and then this extracted image is used to decode the remaining secret images. The focus is to secure the transmitted information even if the channel is revealed, to recognize the authenticity of the extracted images and increase the hiding capacity in a single 24-bit image maintaining the visual quality of the stego-image. Results reveal that the proposed method has low error, comparatively fast computational speed and satisfactory visual quality of the stego-image.
