Analysis of Substitutive Fragile Watermarking Techniques for 3D Model Authentication (original) (raw)

Advances in intelligent systems and computing, 2019

Abstract

Due to the importance of multimedia data and the urgent need to use it in many fields such as industry, medicine and entertainment, protecting them becomes an important issue. Digital watermarking is considered an efficient solution for multimedia security as it preserves the original media content as it is. For 3D graphical models, 3D fragile watermarking aims to detect any attacks to the models and protect the copyright and the ownership of the models. In this paper, we present a comparative analysis between two substitutive 3D fragile watermarking algorithms. The first algorithm is based on adaptive watermark generation technique using Hamming code, while the other algorithm uses Chaos sequence for 3D models fragile watermarking in the spatial domain. The study uses different assessment measures to show the points of strength and weaknesses of both methods.
