Research of privacy-preserving model of office flowchart structure.

Against the problems of privacy leakage caused by the structure of office workflow diagram, this paper constructed a privacy protection model for office automation systems, which proposes an unified anonymization algorithm for actual 1-neighbourhood nodes protecting and the minimum random disturbance method for weights protecting based on the idea of social network anonymization. The model was effectively useful for preventing attackers from recognizing important nodes in an office network by the information of background, the nodes degree and workflow between different nodes, which has been scientifically verified about its usability by experiments.
