Abstract
Steganography is an art of hiding secret messages such that its very presence can't be identified. Techniques which hide more secret data in cover files are better and they will be more better if they doesn't affect transparency of cover signal and make steganalysis difficult. We propose a technique which provide keyless randomization to insert secret information in multiple and variable LSBs. Using this method, binary cover signal is divided into blocks of size 8x8 with 16 bits per sub block, and then checking each sub block's first two MSBs to find how many LSBs will be used for insertion of secret data bits. Results show that there is no noticeable difference between cover audio signal and stego audio signal. Capacity and security increases due to the use of variable number of LSBs for insertion and keyless randomization provided by counting out technique.
