Fault Tolerant Scheme in Steganographic Video Streaming Using n - Repetition Code

Abstract

The rapid exchange of information increases the need for information security, particularly for confidential data information. Confidential data can be secured using a steganography technique by inserting the data into a cover media, in this case, the cover media is in the form of video. This video becomes a medium for sending a message in real time, which is known as video streaming. However, video streaming has the potential for packet loss. This paper proposes a fault tolerant scheme in steganographic video streaming by using repetition code for ensuring the reception of hidden information in a noisy channel such as packet drop in video streaming. This idea comes from the simplest error correction that can minimize errors in the transmission process of data information with the aim of finding the best fault-tolerant value for video steganography. The method used in this study during video streaming is repetition code with n = odd and multiples of 3. This study describes the embedding and extraction process using the Discrete Wavelet Transform (DWT) method on the YUV color space - Luminance(Y) Chrominance (”U” and ”V”), especially Luminance (Y) channel. The measurement of packet loss effect is done by using Peak Signal to Noise Ratio (PSNR) calculation, in which the higher the PSNR value, the higher the quality of the reconstruction. The use of the DWT method which offers high resolution at low frequencies provides a PSNR value of 131.49 dB with the use of the H.265 codec when the packet drop is at a percentage of 15%, as well as message insertion and repetition in every odd frame (1, 3, 5, 7, …853).
