Sparse data encoder and decoder to improve security in video steganography

摘要

Steganography is a technological art to hide text, audio, digital image,s and videos in secret communication,and in the past decade, much research has been carried out the respective field.Currently, secret communications through video steganography are focused on numerous applicationsdue to emerge of social communication networks such as whatsApp, twitter, and Facebook.In video-based steganography, the video with any format have been separated into numberof frames associated to the dividing speed and select few frames for embedding purpose. Theexisting video steganography techniques have some advantages and limitations in informationhiding and so to design a well-intentioned steganography algorithm for improving security androbustness are significant task. The experimental results show that the proposed block-basedtransform domain sparse data encoder and decoder video steganography method provide highsecurity with improved PSNR.
