A Novel 3D Object Watermarking Technique Using Hash Key Cryptography

Watermarking is a widely used technique for embedding invisible signals within digital data, such as images, videos, and audio, to ensure copyright protection and content authentication. This paper presents a novel approach to 3D watermarking, outlining its implementation and key criteria. It also reviews fundamental attacks on 3D watermarking and their corresponding solutions. Unlike previous methods that focused primarily on data hiding without altering the signal, this work emphasizes watermark robustness against manipulation and unauthorized removal. A novel watermarking algorithm using hash key cryptography is proposed, enhancing security in both watermark insertion and extraction processes. The hash key plays a crucial role in encrypting and decrypting the watermark object, making the technique more resistant to tampering and unauthorized modifications.
