摘要：Much research work is conducting to find algorithms for embedding hidden information that contribute in the fields of developing watermarking and steganography. The research work introduced in this paper aims to propose an approach for sending data securely by embedding a hidden cypher text in a stream of images. This study presents an algorithm for hiding information in key frames of a coloured video and then retrieving these data securely and efficiently. Two things should be taken into account, the embedded information should be invariant to the possible changes that might occur for video conversion from one format to another and not all the video frames will be used for hiding the information. Consequently, this research will focus on how to recover the exact version of the original frame in case of any manipulation or update. The proposed work can be divided into two parts, the first one is applying a data encryption method to generate ciphertext, and the second part is to embed the cypher text into frames of a video. The proposed algorithms then are being able to retrieve the original text from the frames efficiently and securely. This research study focuses on contributing more knowledge in both fields.
