Lab reports and code
Worked under the guidance of School of Software, Yao Lin teachers and their graduate students involved in research to protect personal privacy undergraduate direction, is responsible for "PPTD: Preserving personalized privacy in trajectory data publishing" SAGTD translation and thesis of this paper proposed, SAG, STR , MPSTD, C language code MCST five algorithms privacy algorithm.
Privacy About trajectory algorithm
As shown above, a people's hospital records track data through RFID technology, data format <leak tolerance, disease, trajectory Privacy> is, if such data is just the name of the people to remove it advertised its loss of privacy risks still great. For example, a hacker known Xiao Ming went to the emergency room, five p.m. been internal medicine at three in the afternoon, the hacker can filter out data "three in the afternoon went to the emergency room and five p.m. been internal medicine," according to this information, it It can roughly determine its condition, which also leaked Xiao Ming's privacy.
Therefore, this locus data before release is the need for data generalization, this paper is to propose a trajectory Privacy generalization algorithm based on the hospital scene, and my job is to translate the papers and code implementation, and gives detailed lab report.
