Implementation Of Stego-Watermarking Technique by Encryption Image Based On Turbo Code For Copyright Application

In this internet era, there is tremendous growth in the amount of digital data that exchange and disseminate across various internet platforms, especially video. Maintaining copyright for this data is one of the essential things that made people worry. So, there is continuously question around the protection techniques of the data. Video steganography is the human visual system cannot recognise one of the methods that used to hide data inside the digital video file in away. Video watermarking is another technique used to insert additional data inside the digital video to protects its intellectual right against unauthorised manipulation. In this paper, it will use the principle of both steganography and watermarking technique to maintain the video copyright by hiding publisher logo image inside the digital video file by embedding the logo pixel data in LSB of the video frames. The most famous known of the video steganography, watermarking techniques which used in the presented-day has become traditional methods to the attackers. Therefore, there is a necessity to a new smart approach to maintaining the copyright of the digital video. In this paper, an optimised technique is proposed by utilising the advantages of Turbo code to encryption the logo image bits and least significant bit (LSB) approach to embedding the encoded logo pixels inside the frames of the cover video. This process made the system have powerful and high security against the different hacker attacks. The system proved a high quality in result Stego-video by relative rate reach to 98% from the quality of the original video and PSNR equal about (57dB) with high robustness against noise like salt and pepper and Gaussian noise.
