Embodiment Construction

[0036] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0037] Such as figure 1 As shown, the user privacy protection method under the big data mining of the present invention is executed by the user privacy protection system under the big data mining of the following embodiments, including the following steps:

[0038] S1. Obtain the set value of the user's privacy sensitivity to the uploaded data;

[0039] S2. Classify the users, and determine the sensitivity analysis value according to the set value of the privacy sensitivity of the same user for the same uploaded data. If the sensitivity analysis value is greater than the set value, generate an ear...

Abstract

The invention discloses a method and a system for protecting the privacy of users in big data mining environments. The method includes steps of acquiring set values of the privacy sensitivity of the users on upload data; classifying the users, determining sensitivity analysis values according to the set values of the privacy sensitivity of the same kinds of users on the same upload data, generating early-warning information to prompt the users to determine whether to modify the set values of the privacy sensitivity on the upload data or not if the sensitivity analysis values are larger than the set values; setting access permission degrees of data mining algorithms according to the sensitivity analysis values; stopping the corresponding data mining algorithm from accessing the upload data of a certain user if the corresponding set value of the privacy sensitivity of the certain user is larger than the corresponding access permission degree of the data mining algorithm when the data mining algorithm is about to access the upload data of the certain user, or correspondingly processing the data by a data anonymization confusion process and data fragmentation confusion process. The method and the system have the advantages that whether privacy leak can be caused during big data mining or not can be clearly judged, and the privacy of the users can be effectively protected.

Description

technical field [0001] The invention relates to the field of big data security, in particular to a user privacy protection method and system under big data mining. Background technique [0002] Big data is a strategic resource, and the mining of big data can bring huge economic benefits to enterprises. Cloud computing provides technical support for big data. At present, big data mining is facing an important difficulty, that is, big data mining may lead to user privacy leakage. How to protect user privacy under big data mining is an urgent problem to be solved. [0003] Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a method for effectively protecting user privacy in view of the lack of a user privacy protection method under big data mining in the prior art. [0005] The technical solution adopted by the present invention to solve its technical problems is: [0006] A user privacy protection method under big...
