社交網(wǎng)絡(luò)中用戶隱私信息優(yōu)化保護(hù)仿真研究
[Abstract]:The optimal protection of user privacy information in social networks ensures that the information of the network users is not leaked. When the privacy information is protected, the privacy information nodes should be clustered, and the data are lost, and the social network information after the clustering is anonymously and normalized, but the traditional method establishes a formal verification and basis by establishing a formal verification and basis. The trusted privacy information flow model, which integrates privacy information access granularity control to complete the protection of social privacy, can not cluster the privacy information nodes, can not accurately statistics the lost data information and carry out anonymous processing, which leads to the problem of the poor protection effect of privacy information, and proposes a social network based on k- neighborhood isomorphism. This method combines the triangular matrix theory to map the neighborhood sub map of the social network, gives the correlation between the time slices of the adjacent privacy information, and determines the datum node according to the increment of the information change. On this basis, the privacy information node in the social network is clustered to the privacy information node. The generated clusters are generalised inside and outside the cluster, and the social network is anonymously processed, the lost types of information are counted, and the user privacy information in the social network is optimized. The simulation results prove that the proposed method can effectively prevent privacy disclosure and enhance the security of data publishing.
