چکیده
Watermarking has been used time and again for authentication & security of Video. Digital watermarking refers to embedding watermarks in a multimedia documents and files in order to protect them from illegal copying and identifying manipulations. Watermarking is a promising solution to protect the copyright of multimedia data through Transcending, because the embedded message is always included in the data. Because of the fidelity constraint, watermarks can only be embedded in a limited space in the multimedia data. Watermarking techniques can be classified into two types: -1. Spatial & 2. Frequency Domain. In this work proposed to design a new watermarking technique which involves embedding two or more messages or images in a single frame of video for the purpose of security and repeat the same process for N-frames of the video for authentication of whole video. Keywords— Watermarking; Video; Multimedia; LSB; PSNR; Stegnography; DCT; frame; encryption

An improved hybrid image watermarking scheme in shearlet and wavelet domain
Watermarking is one of the best solutions for copyright protection and authentication of multimedia contents. In this paper a hybrid scheme is proposed using wavelet and shearlet transforms with singular value decomposition. For better security, Arnold map is used for encryption. Examining the results and comparing with other methods show that this hybrid proposed scheme with simultaneous utili...

-Today, Digital data security cover such topics as authentication, copyright protection and access control for still images, video, audio and multimedia products. Thus watermarking technique may be relevant in these areas of protection. Based on their domain embedding, watermarking schemes can be classified as Transformed Domain or Spatial Domain. This thesis presents a process to mark digital ...
