Embodiment Construction
[0032] Below, the present invention will be further described in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of not conflicting, the various embodiments described below or the technical features can be combined arbitrarily to form new embodiments. .
[0033] Anonymous region generation methods such as figure 1 shown, including the following steps:
[0034] Receive user service requests, receive service requests sent by users, service requests include user identity, location coordinates, query radius, query points of interest, privacy protection requirements; preferably, privacy protection requirements include k users and the minimum area of anonymous areas, k Users include the user currently sending the service request and k-1 irrelevant users. When a user requests a service, the anonymous server fuzzes the real location of the user into an anonymous area and sends it to the LSP, which contains ...

An anonymous area generation method includes receiving service request of user, receiving service request sent by user, service request including user identity, location coordinate, inquiry radius, inquiry interest point and privacy protection requirement, generating sub-anonymous regions, searching for a plurality of unrelated users through privacy protection requirements, obtaining location information of the unrelated users, and generating a plurality of disjoint sub-anonymous regions; merging the sub-anonymous regions, and calculating the query area of the sub-anonymous regions by the query radius, and merging the sub-anonymous regions according to the query area. The invention also relates to an electronic device, a storage medium and an anonymous area generation system. The inventionnot only effectively protects the privacy of the user, but also effectively reduces the inquiry cost of the LSP and improves the service quality.
Description
technical field [0001] The invention relates to the technical field of information security, in particular to an anonymous area generation method, an electronic device, a storage medium and a system. Background technique [0002] In recent years, the development of information technology, especially the rapid development of mobile positioning technology and wireless communication technology, has made the application of location-based service (LBS, Location Based Service) widely popularized. Through LBS, users can query interested and location-related information anytime and anywhere. Serve. However, since all location-based services require the user to submit as accurate location information as possible to the LBS service provider in order to obtain accurate and convenient services, this exposes the user's location information to the server of the location service provider, and the service provider Private information such as home address, workplace, and health status can b...
