【摘要】 数字产品存在着大量盗版和侵权问题,已成为信息数字化发展的主要障碍。为了保护数字产品的知识产权,采用DRM技术,利用硬盘序列号设计了一种基于机器指纹的数字版权控制方法,将用户的机器指纹与许可证绑定,实现对数字内容的使用控制。由于机器指纹的唯一性和只读性,使得数字内容只能在特定的机器上使用,不仅防止了数字内容的非授权访问,而且,即使是授权用户也不能得到解密后的数字内容,从而有效地保护了数字内容的版权。更多还原

【Abstract】 Large pirate problem exists in digital products,and it becomes the most drawback of digital information development.To protect the intellectual property rights of digial products,DRM technology is adopted.A digital rights control method based on machine fingerprint is designed using hard disk sequence number.Use control of the digital content is implemented by binding user machine fingerprint to licence.Because of the unique and read only speciality of machine fingerprint,the digital content can be used only in the special machine.Not only non-authorization access of the digital content is prevented,but also authorized user can not get hold of the decrypted digital content,thus digital rights are protected effectively.更多还原
