A temporal domain audio steganography technique using genetic algorithm

As communication is being done by electronic means in open air generally, security of data is highly desirable. One such technique of doing this is steganography. The requirement of a system that ensures increasing capacity, robustness and security of embedded data there have been so many variants in existing steganography technique. Due to this diversity it needs some technique to optimize the existing traditional substitution technique. The audio file is chosen as cover file due to its practical availability and “Masking Effect”.
