摘要:

针对泛在共享环境下信息频繁跨节点、跨系统交换时有意或无意留存而导致的隐私信息泄露问题,提出了一种基于双重存证的跨域流转多副本发现机制,可实现对流转信息的传播路径、传播方式进行溯源,并构造信息的多副本传播图。根据存证时机和方式的不同,双重存证包括流转主动存证和操作被动存证,信息在被分享前,由信息分享者主动记录传播路径和传播方式,生成流转主动存证记录;信息在被操作前,由系统自动记录传播路径,生成操作被动存证记录;相比单一存证,双重存证能够提高构造的信息多副本传播图的完整性和真实性,能够发现存证行为异常的节点并进行处置;基于社会惩戒理论,证明了存证行为异常发现与处置的有效性。实验开发了针对OFD的双重存证多副本发现原型系统,验证了所提机制对信息传播图构造完整性的提升。

Abstract:

To solve the problems of the privacy information leakage caused by the deliberate or inadvertent retention of information when information was frequently exchanged across nodes and systems in a ubiquitous sharing environment, a cross-domain multi-copy of flow discovery mechanism based on dual certificate storage was proposed, which could trace the propagation path and channel, and construct a multi-copy propagation graph of the information.Depending on the timing and method of certification, the dual certification was comprised active circulation certification and passive operation certification.Before the information was shared, the information sharer actively recorded the propagation path and method to generate active circulation certification records.Before the information was operated, the system automatically recorded the propagation path to generate passive operational certification records.Compared with single certificate storage, the dual certificate storage could improve the integrity and authenticity of the constructed multi-copy propagation graph of information, and could detect nodes with abnormal certificate storage behavior and provide disposals.Based on the theory of social punishment, the effectiveness of abnormal certificate storage behavior detection and handling was demonstrated.A prototype system for multi-copy discovery of OFD with dual certificate storage is developed, the improvement of information dissemination graph construction integrity by the proposed mechanism is verified.
