Abstract

Multimedia steganography is one of the most important technologies to secure different kinds of data in today networked environment. It can embed large amounts of data safely inside multimedia files in objective to deviate the attention of attackers of existing data. In addition, the data encryption techniques can be added with steganography technologies to strength data protection. In this paper, we proposed a method to hide image and text files inside a video using LSB technique and chaotic systems. Two keys are used to secure data such that first key employed to select specific frames form video and the second key to select columns inside selected frame images to embed data. Three image quality measures are used to compute the quality of Stego images in our experiments including MSE, PSNR and SSIM. Experimental results show that the proposed method is secure enough to prevent attackers from stealing encrypted images and text files.
