摘要
Abstract
Based on researches, it is discovered in the paper that the isolated watermarked vertex/cluster problem exists widely in classical 3D mesh fragile watermarking. Through theories and instances the paper analyzes the causes of isolated watermarked vertex/cluster as well as security risks that it may bring about. Then targeting at the isolated watermarked vertex/cluster problem, based on classical algorithm, the paper puts forward an improved algorithm, which, while embedding watermarks into watermarked rertexes, treats non watermarked vertexes with pseudo-watermarks, so that the relationship among watermark vertexes is strengthened and the isolated watermark vertexes are eliminated. Experiment results demonstrate that the improved algorithm effectively solves the isolated watermark vertex /cluster problem.关键词
