【摘要】 首先,提出开放式数字版权管理ODRM(Open Digital Rights Management)的概念,并以ODRM为基础,针对水印功能的需求提出一种新的数字水印层次模型。然后,利用ODRM层次模型实现了一种基于概率算法的多重文本数字水印(MTDW)算法,该算法具有较好的隐蔽性和安全性,同时针对攻击者对文本文件和水印信息的破坏,具有较好的检测和纠错提取性能。最后,通过概率算法理论和对攻击试验数据的分析,证明该算法的具有较高的可靠性。更多还原

【Abstract】 First of all,the concept of ODRM is offered,and In order to meet the requirements of ODRM,a new hierarchical model of digital watermark is proposed based on the demand for the function of watermark.Multiple textual digital watermarking algorithm is achieved by using the ODRM hierarchical model,which is safe and hidden very well,Moreover,it has a strong ability of detection and error-correction after the demolishing made to the test content or watermarking by the attackers.Finally,through analyzing the probability algorithm theory and the data coming from attacking experiment,this algorithm is proved to have high reliability.更多还原
