Embodiment 2

[0163] This embodiment provides a device for processing user characteristic attributes, which is applied to a system including a policy center, a first-level gateway, a second-level gateway, and users. Please refer to Figure 5 , the device consists of:

[0164] Initialization module 501, used for system initialization, includes the following two submodules:

[0165] The system parameter generation module 5011 is used for the policy center to generate the public and private keys of the policy center and other required system parameters according to the selected security parameters in advance, and select encryption parameters;

[0166] The sending module 5012 is used for the policy center to send the system parameters to the first-level gateway, the second-level gateway and the user respectively, and for the policy center to send the system parameters to the user registration request after receiving the user registration request. The user sends the encryption parameter;

Abstract

The invention discloses a processing method and apparatus for characteristic attributes with privacy protection. In order to efficiently process the characteristic attributes of a large number of users, the processing method and apparatus for characteristic attributes with privacy protection divide the large number of users according to communities, and gateways have a secondary structure, and each community is corresponding to one primary gateway, and all the primary gateways are corresponding to one secondary gateway. The processing method for characteristic attributes with privacy protection includes 5 steps: system initialization, ciphertext generation for a user characteristic attribute set, ciphertext calculation for users of single community with privacy protection, ciphertext calculation for the large number of users with privacy protection, and statistical result acquisition for characteristic attributes of the large number of users. The processing method and apparatus for characteristic attributes with privacy protection can realize statistical analysis of the characteristic attributes of the number of users while ensuring that the user characteristic attribute set is notleaked, thus having the advantages of being high in practicability, and providing powerful technical support for situation analysis ad strategy making for the industries, such as e-commerce, electronic medical, e-government, public sentiment management, and insurance.

Description

technical field [0001] The present invention relates to the technical field of information security, in particular to a processing method and device with characteristic attributes of privacy protection. Background technique [0002] In order to grasp market orientation, population health status distribution, population structure distribution, etc., and formulate more reasonable strategies (such as marketing strategies, health care strategies, insurance strategies, etc.), And other fields usually need to conduct statistical analysis on the user's characteristic attributes. Feature attributes are personal sensitive information, and users often do not want to disclose their own feature attribute information. At the same time, with the development of technologies such as sensor networks and the Internet of Things, the number of users accessing the Internet is massive. Therefore, how to statistically analyze the sensitive data of a large number of users without leaking the sens...
