Image steganography using 24-bit bitmap images
Abhisek Saha, Sholanki Halder, Shama Kollya · 2011
Steganography is a method of hiding data in a seemingly innocent medium, like an image, a sound or a video clip, which doesn't arise any suspicion as it travels from the sender to the receiver through public communication channels. In our proposed algorithm, we have tried to implement Steganography by hiding data in the pixel which occurs the most in a 24-bit bitmap image. First we calculate which pixel value is most frequent. We then modify only those pixels to hide the data using simple LSB modification and write them to the output file.
