Watermarking Images via Counting-Based Secret Sharing for Lightweight Semi-Complete Authentication

Watermarking is the process of embedding specific data to prove ownership copyright authentication. It is needed whenever media files are used without proper permission being granted. The current watermarking challenge comes from the ownership proof especially as slight tampering occurs on the multimedia file which injure the watermarking causing difficulty in its copyright proof. This paper proposes utilizing counting-based secret sharing strategy to allow validation of ownership RGB watermarking even if some of the image file is interfered. The authors validate image watermarking partially as lightweight semi-complete verification, which is not possible in the normal random-stream watermarking schemes. Although the work is still in its early stage, it is promising research showing real attractive contribution opportunities. The work is tested and compared to other strategies in aspects of robustness, capacity, and security, providing attractive remarks worth noting. The study evaluation results showed interesting contribution believed to be pioneering.
