Real-time implementation of reversible watermarking

Abstract

In today’s Internet-connected world, tampering of digital images by malicious users has become very common. This clearly is a direct violation of one’s intellectual property rights, and hence, image protection by resolving rightful ownership is gaining utmost importance. Reversible watermarking (RW) techniques are a potential replacement for conventional watermarking systems, in case if the images to be protected are very sensitive. Studies have suggested that these methods offer greater balance among the requirements of watermarking such as invisibility, robustness, and capacity. This chapter gives an overview of the RW techniques, their vulnerabilities, and recommendations for future development. Performance issues related to the real-time implementation of watermarking systems through various algorithms are also featured. Finally, an extension of real-time implementation of RW approach based on asynchronous architectures is introduced.
