Review on 3D object watermarking techniques with possible attacks and their solution

Abstract

A watermark inserts an invisible signal inside the data(image, video and audio), for a number of reasons, which includes embedding copyright and caption information. In this paper, we first outline the introduction of 3D watermarking and then give the basic requirements of 3D watermarking. Fundamental attacks and their solutions on 3D geometry watermarking is then reviewed. The past work was concerned with hiding the data, irrelevant of distorting the signal or tampering the data with the intention of removing a watermark. In contrast the watermarks are popularly used to avail strength in signal alteration, managing copyright issue, and preventing changes. Several recent approaches that quotes these issues are discussed in this paper.
