Summary
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 applications due 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 number of frames associated to the dividing speed and select few frames for embedding purpose. The existing video steganography techniques have some advantages and limitations in information hiding and so to design a well‐intentioned steganography algorithm for improving security and robustness are significant task. The experimental results show that the proposed block‐based transform domain sparse data encoder and decoder video steganography method provide high security with improved PSNR.
