Problems solved by technology

[0004] On the one hand, in the existing data collection mechanism, users often directly upload personal data to the server, and then the server processes the data, but the server is often untrusted, and the service provider may Leaking the user's personal privacy data; on the other hand, most of the existing data collection methods adopt the method of adding noise to the data, but the added noise does not consider the relationship between attributes, and it is not applicable to multi-dimensional data

Embodiment 1

[0020] Please refer to figure 1 , a method for collecting sensitive data, comprising the steps of:

[0021] S0, the server generates a corresponding pseudonym ID for the i-th client i ', where i ranges from 1 to m, and m represents the total number of clients.

[0022] S1. The server judges whether the instruction information sent by the client is a creation instruction, and if so, creates a disturbance group G j , and select the client as the owner client of the disturbance group, otherwise, select the client as a member client, and assign the member client to the corresponding disturbance group, and the The above creation instructions include the public key PK of the group owner client j , where j represents the sequence number of the disturbance group;

[0023] The specific assignment of the member clients to the corresponding disturbance group is as follows:

[0024] The member clients are assigned to corresponding perturbation groups under pseudonyms.

[0025] The i...

Embodiment 2

[0047] Please refer to figure 2 with 3 The difference between this embodiment and Embodiment 1 is that the present invention will further illustrate how the above-mentioned sensitive data collection method of the present invention is realized in combination with specific application scenarios:

[0048] S0, the server generates a corresponding pseudonym ID for the i-th client i ', where i ranges from 1 to m, and m represents the total number of clients.

[0049]S1. The server judges whether the instruction information sent by the client is a creation instruction, and if so, creates a disturbance group G j , and select the client as the owner client of the disturbance group, otherwise, select the client as a member client, and assign the member client to the corresponding disturbance group, and the The above creation instructions include the public key PK of the group owner client j , where j represents the sequence number of the disturbance group;

[0050] The specific as...

Abstract

The method for collecting sensitive data provided by the present invention is to create a disturbance group or join a disturbance group through the client, and the member client uses the public key PK of the group owner client j Encrypt personal data, and forward the encrypted data to the group owner client through the server in a preset message format, and the group owner client receives user messages sent by all member clients in the disturbance group data, and PK with the public key of the group owner client j Matching private key SK j Decrypt to obtain the decrypted original data set, and disturb the decrypted original data set to obtain the disturbed data set and send it to the server, which can avoid the intervention of third-party servers and improve the security of personal data collection Resilience, while satisfying the availability of data, it can resist the attacks of internal malicious users and untrusted servers, protect the privacy of data, and ensure that the privacy of users is not leaked.

Description

technical field [0001] The invention relates to the technical field of information security, in particular to a method for collecting sensitive data. Background technique [0002] In recent years, with the increasing popularity of intelligent terminals with collection functions and wireless communication technologies, various services based on data collection (such as medical data collection or personal asset collection) are developing rapidly, and now they have covered all aspects of people's lives. [0003] In the process of data collection, the data uploaded by users contains sensitive personal information, such as medical expenses, disease information, health status, hobbies, religious beliefs, and home addresses. If users directly upload data containing sensitive attributes without adopting appropriate data protection mechanisms, personal privacy may be leaked; and improper application of collected data may also lead to personal privacy leaks. Moreover, the more accura...
