Embodiment Construction

[0031] The privacy protection method published by transactional data flow, its application environment is as follows figure 1 As shown, the sliding window data is anonymized to satisfy ρ-uncertainty and released for use by data miners.

[0032] The process of a privacy protection method published by a transactional data flow is as follows:

[0033] Step 1: In order to facilitate the calculation of support and confidence, the data of the initial sliding window is converted into a cover set, that is, for cover(item) is a collection of transactions containing items, and uses the static anonymous method proposed by Jianneng Cao et al. to anonymize it to satisfy ρ-uncertainty and publish it.

[0034] Step 2: Dynamically anonymize the sliding window, establish the affected sensitive association rule tree ASRT (Affected Sensitive Rules Trie) according to the deleted and added transactions, and use the payoff tree to suppress the project. During the process:

[0035] First, initial...

Abstract

The invention discloses a privacy protection method for transactional data flow publishing, data are anonymous by adoption of sliding windows, the recent data information can be well processed by the sliding windows, and therefore privacy requirements can be ensured to be satisfied by any sliding window and data validity is maintained as much as possible, thereby facilitating analysis by data miners.

Description

technical field [0001] The invention relates to the technical field of data security, in particular to a privacy protection method for transactional data flow publishing. Background technique [0002] With the rapid development of network information technology, in order to meet the needs of business decision-making and scientific research, a large amount of data containing personal privacy information is stored and released by government departments and commercial organizations. As a means of information sharing, data release not only provides convenience for data exchange and data sharing, but also poses a serious threat to data privacy. If the data publisher does not take appropriate protection measures, it will cause the leakage of sensitive data, which will bring harm to the data owner or the enterprise. The issue of privacy protection in data publishing mainly considers the following two aspects: ① Ensure that the published anonymous data does not reveal the private i...
