An art of invisible communication by embedding secret information in other sources like text, image, audio, and video is called steganography. A high security data hiding technique is proposed in this paper. Selected frames from the video are cropped into four equal parts, block of secret data is hiding in each three channels of crop of a frame using LSB technique in a predefined sequence, and then image crops are joined to get stego image/ frame. This stego frame is replaced in video in its original position. Comparative study is performed between proposed approach and existing approach using different metrics such as visualization test, MSE, PSNR and CPU time. Experimental results shows that the proposed approach is more secure compared to the existing approach.
