Hiding Messages Using Motion Vector Technique In Video Steganography

摘要

Steganography is the art of hiding information in ways that avert th e revealing of hiding messages.Videofiles are generally a collection of images. somost of the presented techniques on images and audio can be applied to video files too. Thegreat advantages of video are the large amount of datathat can be hidd en inside and the fact that it is a moving stream of image. Inthis pap er, we proposed a new techniqueusing th e motion vector, to hide the data in the moving objects. Moreover, to enhance the secu rity of the data, the data is encrypted by using th e AES algorith m and then hided. The data is hided in the horizontal and the vertical components of the moving objects. The PSNR valu e is calculated so that th e qualityof the video after th e data hiding is evaluated.
