Watermarking is the process that embeds data called a watermark into a multimedia object for its copyright protection. The digital watermarks can be visible to a viewer on careful inspection or completely invisible and cannot be easily recovered without an appropriate decoding mechanism. Digital image watermarking is a computationally intensive task and can be speeded up significantly by implementing in hardware. In this work, we describe a new VLSI architecture for implementing two different…

Hardware implementation perspectives of digital video watermarking algorithms
TLDR
The time and area constraints that must be satisfied by a successful hardware implementation of a well-known video watermarking algorithm are discussed and a hardware architecture that implements the algorithm under the constraints is proposed.
Protecting publicly available images with a visible image watermark
TLDR
The technical goals for watermarking include applying a readily visible mark to the image that clearly identifies its ownership, permitting all image detail to be visible through the watermark, and making the watermarks difficult to remove.
