Video steganography method based DWT

الملخص EN

The video steganography is a technique to hide information inside video file.Whereas video Steganography is a very important task in real life where the users want to keep data, so the steganography process used for the secure data transmission from the sender to receiver through the internet.

Least significant bit (LSB) insertion technique operates on LSB bit of the media file to hide the information bit.

In this paper steganography technique used to hide the information inside compressed video as development of a standard method in order to benefit from the advantages of the compression process, which added to the video, these features are reduce storage size of video, and reduce bandwidth to transfer data in faster way with save time that requires transferring video during the network.

The video compressed by using discrete wavelet transform DWT because it an efficient method that can be used to perform an efficient compression technique.

The video contains number of frames played over a period of time.

By using the proposed method can hide information in any number of these frames for various video sizes and in specific location of the pixels.

And has been verified from performance of proposed method by retrieval original information without any lost, and by using several quality measures performance to measure the results of proposed method found it's a good, acceptable compare with results of other methods used in more researches.
