Abstract

Steganography is the art of science that is concerned with hiding communications by hiding secret information inside a medium as a carrier, called cover medium, to be sent over communication channels to meant parties. Information hiding could be done with simple and direct methods; however we should increase hidden information security as possible by developing and using more robust ways. One of the most used techniques is Lest Significant Bit (LSB) Substitution. The direct approach that uses LSB Substitution is Sequential LSB that embeds data sequentially, but it is too simple and easy to attack. So, to increase hidden information security, we must use this technique of hiding in random way. Many algorithms were set to increase the securit...
