基于语音权重的关系数据库水印算法研究

摘要

We enunciate the need for watermarking database relations to deter data piracy,identify the characteristics of relational data that pose unique challenges for watermarking.This paper creatively proposes a novel method for watermarking relational database,which uses speech signal as watermark embed into database according to the weight of attributes.Experimental results show that the proposed scheme is robust against various forms of attacks.Our approach is more intuitive,and it support easy watermark identification.%阐述了水印关系数据库在数据阻盗版中的需要,明确了对水印技术提出挑战的关系型数据的特点。创造性地提出了一个新型的方法,为关系型数据库产生水印,根据分配的权重不同,把语音信号嵌入到数据库中作为水印。实验结果表明在各种不同的攻击下该方案是健壮的。该方法更加直接,并支持简单的水印识别。
