连续的数据库数字水印检测算法

Sequential database digital watermarking detection algorithm

数据库数字水印的检测是数据库数字水印方案的关键环节之一,优良的检测方案可以增强水印的检测效率及性能.提出了一种连续的数据库数字水印检测算法,在保证检测准确度的情况下,可以较大幅度地提高数据库中水印检测的时间效率;对于数据库数字水印的子集替换和子集删除攻击具有较强的免疫性.通过实验对该算法进行了验证和比对分析,证明该算法具有比较理想的效果.

A new sequential watermarking detection algorithm named SWDA was presented, which could improve the efficiency of the watermarking algorithm and the ability of resistance on subset selection attacks and subset alteration attacks and, at the same time, ensure the accuracy of the detection result. The experimentations also demonstrated these effective results.
