A data hiding technique for digital videos using entropy-based blocks selection

The technique of hiding knowledge in certain details is steganography. One of the main trends of computer infrastructure and connectivity following the advent of the Internet has been cyber protection and information security. It is required to hide valuable information like passwords, bank details, and other personal documents. In this perspective, a novel algorithm is proposed for data hiding in digital videos using entropy-based blocks selection to make the message more secure. In which firstly random frames are selected by using a key and then random macroblocks are selected. The macroblocks with high entropy have chosen to hide the data in them. This paper presents a critical analysis driven from the literature and the experimental results. To quantify the results and to evaluate the performance of distinct steganography techniques, different quality metrics like peak signal-to-noise ratio (PSNR), mean squared error (MSE) & bit error rate (BER). have been used. Experimental results show that the proposed algorithm outperforms the other state of art techniques and also able to hide the secret message in the video without adding the noise and other distortions.
