Abstract
This paper produces a developed method based on steganography techniques to prevent
intruders from obtaining the transmitted information. This work is based on a combination of
steganography and cryptography techniques to increase the level of security and to make the
system more complex to be defeated by attackers. The algorithm used for encryption is the
RC6 algorithm.
Two methods of hiding are used in this work: the first method is the Least Significant Bit
(LSB) and the second is the proposed and modified method used to hide bits in LSB of
iterated loop in brightness, red, green and blue of hiding image. The proposed method was
tested using standard objective measures such as Mean Square Error (MSE) and Peak Signal
to Noise Ratio (PSNR). A comparison between the two methods is performed.
