Steganography Algorithm within 2-LSBs with IndicatorsBased Randomness

Abstract

Steganography is the field of science which is concerned with covert communications by hiding secret information within an innocent-looking medium, and sending the medium as a carrier over the communication channel. One of the most used techniques is Least Significant Bit (LSB) Substitution, which hides secret data by substituting the LSB of each binary sequence with the bits of the secret data. In our work we introduced a new algorithm of random information hiding based on indicators. Images were used through our research as the cover mediums for experiments and image quality metrics were used for evaluation.
