Utilization of Steganographic Techniques in Video Sequences

Abstract

The fast growth in the demand and consumption of the digital multimedia content in the previous period has led to some effective concerns over issues such as content security, digital rights management, and authenticity. Hiding Data is an important way of recognizing copyright protection for digital multimedia. Digital video/ images became very common choice for hiding data ( hold large amounts of data) and the selection of suitable pixels in the video frames, which are used to store the secret data is very important for an effective and successful embedding process . If pixels are not selected sensibly, undesired spatial and temporal perception problems occur in the stego-video. This paper will concentrate on the use of digital video/images as cover to hide data. The proposed steganography algorithm based on color histograms for data embedding into Video Sequences directly, where each pixel in each video frame is divided in two parts, the number of bits which will be embedded in the right part are counted in the left part of the pixel. This algorithm is characterized by the ability of hiding bigger size of data and the ability of extracting the written text without errors, besides it gives a high level of authentication to guarantee integrity of the video/ images before being extracted. Additionally, the data were embedded inside the video/ images randomly which gave the video/ images a difficult security and resistance against extraction by intruders.
