Abstract

With the increase in internet usage, data exchange happens at a higher pace, but with this comes the risk of security breaches. Hackers often target data exchange, making security a top priority. To address this issue, steganography has proven to be an effective solution. It involves concealing confidential data behind seemingly innocuous cover files, making it less likely to be detected. In a recent paper, the use of Sine chaotic map was proposed as a way to enhance security. Chaotic maps are sensitive to initial values, non-linear, and non-periodic, making them ideal for encryption. The proposed method involves using a video as the cover file and an image as the secret data. The video is split into frames in YUV form, and the position of pixels is changed using the sine chaotic map. The hamming code is used to encrypt and embed the secret information in the frames, after applying the cycle shift. Using multiple encryption techniques before embedding secret data in the video increases the level of security and ensures that the information can be extracted from the stego video without any losses. The results of this method show that it is highly effective, as evidenced by the PSNR value of 78.23dB for the stego video with high value of hiding capacity and the SSIM of 0.99 between the cover video and stego video.
