VIDEO STEGANOGRAPHY BASED ON SINE CHAOTIC MAP AND THE RSA TECHNIQUE

With the increase in internet usage, data exchange happens at a faster 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.Steganography conceals confidential data behind seemingly innocuous cover files, thereby reducing the likelihood of detection.A recent paper proposed the use of the Sine chaotic map 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.After applying the RSA technique and cycle shift, the hamming code encrypts and embeds the secret information in the frames.The use of multiple encryption techniques prior to embedding secret data in the video enhances security and guarantees the extraction of information from the stego video without any loss.The results of this method show that it is highly effective, as evidenced by the PSNR value of 78.23 dB for the stego video with a high value of hiding capacity and the SSIM of 0.99 between the cover video and the stego video.
