Robust Digital Video Watermarking using Reversible Data Hiding and Visual Cryptography

A Hybrid Novel Approach of Video Watermarking

“…Spatial domain watermarking techniques are simple with low time complexity. Redundant part of the carrier signal is used for embedding digital data [1] and [24].…”

“…Fm denotes the frequency band with gain factor k and (u, v) are the DCT coefficients in 8×8 block [1].…”

“…P and B frames are motion compensated while residual prediction error signal frames are split into a block of 8×8 pixels. In the next step, the watermark block is transferred using DCT [1] and added as shown in Figure 3.…”

“…Watermarking provides copyright protection to the digital data by hiding some appropriate information. Watermarking itself is categorized into two broader types called visible and invisible watermarking [1]. The visible watermarking is placed in the background of the digital document to signify the owner or the authority name.…”

“…The approach implemented in this paper follow all these requirements. Video watermarking techniques are used in various applications such as Copyright Protection, Broadcast Monitoring, Data Authentication, Owner Identification, Fingerprinting and Security [3].…”
