Secure information using steganography and watermarking

الملخص EN

This paper presents secure hiding of information which provides confidentiality and authentication based on techniques of video steganography and watermarking.

The proposed system embeds both secret information and watermark image into cover video in random fashion using LSB method.

For each embedding process, different sequences of frames are be selected randomly depending on initial seed value.

The system includes two modules embedding, extraction.

firstly, in embedding module, load the input arguments which are represented by cover video, secret information, watermark image, and initial seed, and finally, produced the stego-video which is the original cover video hides inside it the secret information, watermark image.

In the extraction phase, the system receives the stego video in additional to the seed value and number of frames used in embedding phase.

The extraction module uses both initial seed and number of frames to generate the same sequence of frames as in embedded phase, then extract secret information and watermark image.

The authentication of the sender is tested by match between received and stored watermark.

For evaluation of the proposed system and to be ensure that the original media (video) is not affected significantly due to embedding process, many measurements are being calculate from video before and after hiding process such as histograms, mean square error (MSE), peak signal to noise ratio (PSNR) and hiding time.

The system is tested during embedding and extraction modules considering using several cover videos, secret information and seed values.-
