Abstract

The concealment of the most important means used by the security institutions with critical communications in all countries of the world, they provided the technology of high security, especially in the communication networks and the Internet. Summarized algorithm concealment improved transfer confidential letter to the formula of (Binary) and then encrypted using a key agreed upon by the two parties (sender and recipient), followed by the division of the image to be hide data where clips blocks size (8*8) and account values ​​standard deviation (Standard Deviation (STD)) for each section are then finding less and the largest value of a standard deviation in addition to the median value, then isolate sections where the value of the standard deviation less Oomsawih of median value to be key concealment (ie be adopted as locations to hide) and that by including all bit of message into the (LSB) for each section of the selected sections. Used measures of efficiency (PSNR), (MSE), (BER) for the purpose of measuring the efficiency of the algorithm and the adoption of improved language (MATLAB).
