抗合谋指纹能够从多用户合谋伪造数字资源中识别出参与者,为依法惩治叛逆者提供不可抵赖法律凭证,保护数字资源信息安全。本文设计了抗合谋指纹协议,将抗合谋指纹技术应用于解决数字档案公共网络使用中信息安全问题。协议以提取的抗合谋指纹作为法律证据追踪叛逆者,有效解决数字档案取证不具有唯一性难题,使得叛逆者在法律面前不可抵赖,对非法复制数字档案起到法律惩罚、震慑作用,保护了数字档案信息安全。测试表明协议能够正确追踪到叛逆者,未发生误判、漏判现象。
Anti-collusion fingerprinting can identify participants from multi-user conspiracy forgery of digital resources, provide non-repudiation of legal evidence for punishing rebels in accordance with the law, and protect the security of digital resource information. In this paper, the anti-collusion fingerprinting protocol is designed and the anti-collusion fingerprinting technique is applied to solve the information security problems in the public use of digital archives. Agreement to use anti-collusion fingerprints extracted as legal evidence to track the traitor to effectively solve the digital file does not have a unique problem of evidence collection, making the rebels in the law before the non-repudiation of illegal copying of digital files play a legal punishment, deter the role of digital protection File information security. Test shows that the agreement can correctly track the rebels, there is no miscarriage of justice, leakage of justice phenomenon.
