A Novel 3D Object Watermarking Technique Using Hash Key Cryptography

摘要

For a variety of purposes, a watermark inserts an invisible signal within the data (image, video and audio), which involves embedding copyright and caption details. First, the proposed research work outlines the implementation of 3D watermarking in this paper and then provide the basic 3D watermarking criteria. Fundamental attacks and their solutions to the watermarking of 3D geometry are then reviewed. The previous work concerned hiding the data, not distorting the signal or altering the data in order to delete a watermark. Watermarks, on the other hand, are widely used to allow use of power in signal alteration, copyright management and modification prevention. In this article a novel algorithm for image watermarking using hash key cryptography technique is proposed. The algorithm for inserting and extracting the watermark is proposed. Hash key is used in encryption and decryption of the watermark object. It is making watermarking technique more secure.
