Highly Secured Multilayered Motion Vector Watermarking

摘要: With the recent development in multimedia, video has become a powerful medium of information. To exploit temporal redundancy during compression, motion vector estimation is required. Now-a-days internet and digital media very popular, which made data authentication security challenging task. Digital watermarking was introduced to provide authentication. Though, it not enough prevent unauthorized access by third parties. access, encrypted using secret key known only user. This process as cryptography. In this paper, an algorithm been proposed embed watermark inside calculated vector. The position bit will depend on provided correlation values between four original recovered experimental frames are 0.97, 0.98, 0.98 0.91 respectively whereas structural similarity index metric (SSIM) them 0.87, 0.90 0.68, respectively. high SSIM shows effectiveness method.
