Hide Encryption Secret Message in Video Frame Based on MapReduce

Abstract

The necessity to secure confidential data has arisen, and in order to eliminate the weaknesses in some previous research that hide the data in the video without encryption. This paper proposed a method of video steganography after encrypted data by using Advance Encryption Standard (AES) algorithm then sending it to the other party with high security and embedding rate. In addition facilitating dealing with video frames as large data for the purpose of analyzing, dividing and controlling frames easily, using the MapReduce method. This is done by dividing the video into frames, then, encrypt the message by the (AES) algorithm. And these frames and the encrypted message will be entered into the MapReduce system. Firstly the Master will divide the video frames and the encrypted message into four parts.  Each part will be sent to MapReduse stages, as each part will be processed separately. In the MapReduce stages, some frames will be selected from a series of frames for the purpose to hide the message in them. Then the hiding process will be done using theLeast Significant Bit (LSB) method which uses the stego secret key (. After that, the stego frame will be generated, and so on until the message is completely hidden. Finally, collect all frames from all parts to reconstruct the stego video. The results of this method is efficiency, transparency, robustness, powerful in stego video , high capacity , and high security the attacker cannot detected any suspicious differences in a stego video. This results is obtained through use many measurements PSNR, MSE, Entropy, correlation coefficient.
