Robust video watermarking algorithm based on motion frames and encryption

Rapidly growing technologies over the internet are used to transfer digital media content at a high rate nowadays. The growth in these technologies results in the creation of identical copies of original multimedia data easily. The creation of these identical copies states the false claim of the ownership of digital media by any malicious user. The proposed method suggests protecting these types of the false claim by inserting a watermark into selected motion frames. Before embedding the watermark, it is scrambled by using an algorithm having a secret key. With help of this key, the scrambled watermark will be reconstructed whenever it is required. With the help of DWT method along with using SVD technique watermark is inserted into the selected frame from the original media. The results of the proposed algorithm show that the scheme is secure and robust against different types of attacks whether it is intentional and unintentional. The proposed scheme is found more secure for the protection of false claims of malicious users over digital media.
