Abstract

The invention discloses a K-anonymization based motion track data privacy protection method and system. A K-anonymization technology is adopted for generalizing motion track data and hiding real data, the generalized data is encrypted at the same time by establishing a database trigger mechanism, and the generalized data is decrypted and recovered into original data by utilizing a design data recovery algorithm, so that privacy protection of the motion track data is realized. According to the K-anonymization based motion track data privacy protection method and system, a K-anonymization generalization algorithm is improved, so that the generalized track privacy data can be recovered, it is ensured that the original data can be recovered while the privacy data is hidden, and the data completeness is realized.

Description

technical field [0001] The present invention relates to the technical field of privacy data protection, in particular to a K-anonymous motion track data privacy protection method and system. Background technique [0002] k-anonymity is an anonymous privacy protection technology proposed by Samarati and L. Sweeney in 1998 for publishing public databases or microdata. In 2002, L. Sweeney named it the k-anonymity model. Effectively avoid the leakage of private information caused by link attacks and other means, since then the privacy protection technology based on k-anonymity has become a research hotspot. [0003] k-anonymity is to anonymize some attribute values ​​in the original data set to form an anonymous data set that meets certain anonymity requirements and can be used for data release. For any value row projected onto these attributes, there must be at least k-1 at the same time Other record attribute values ​​are exactly the same as this value row. In order to ensur...
