Abstract
Steganography is a technique to hide the secret data inside some other cover files (like text, image, audio, etc.) in such a way that it prevents the detection of the secret data within the cover files. In this paper, a new scheme of concealing secret data has been introduced where the locations of hiding the secret bits will be generated by linear feedback shift register (LFSR). Using LFSR, we will compute random numbers (within a given range) which will determine the specific pixels where secret bits of the secret data will be concealed. We use least significant bit (LSB) technique where the secret bit will be stored at the least significant bit position of the pixel. Choosing the cover pixels from cover image randomly will strengthen the security of LSB technique.
