Image steganography technique based on adaptive random key generator with suitable cover selection

In this paper, a new scheme for a random key generator as a method to implement Steganography has been introduced. The main idea is based on principle of LFSR stream cipher. The simplicity of the design the LFSRs based on user demand that will give the user some experience about the best generator which will fulfill not only the requirement of the cryptography but also Steganography. Here, the factor called beta has been created. The beta factor will effect on the selection of the cover image from database of covers. In additional, it will play a great role in the system to specify the user demand on the security level that made the designed system fast to handle huge database. The quality measurement that applied on the obtained result was subjective as well as objective which shows the affection of beta on the obtained result from both the vision.
