Embodiment Construction

[0053] 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. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not constitute a conflict with each other.

[0054] Such as figure 1 As shown, the location privacy protection method based on granularity control of the present invention includes the following steps:

[0055] (1) judge whether there is an LBS application list stored in the mobile device, if there is then proceed to step (2), otherwise create an LBS application list, then proceed to step (2);

[0056] (2) Set the privacy level for each ...

Abstract

The invention discloses a location privacy protection method based on granularity control, which includes: judging whether an LBS application program list is stored in a mobile device, and if so, setting a privacy level for each LBS application program, which corresponds to the LBS application program It will obtain the location accuracy and judge whether there is a privacy policy library in the mobile device. If it exists, it will continue to monitor the LBS request from the LBS application, and obtain the location corresponding to the LBS request when receiving the LBS request Information, read the location accuracy corresponding to the LBS application program from the privacy policy library, and judge whether to perform fuzzy processing on the location information according to the location accuracy, and if necessary, turn to the step of requesting the corresponding location according to the LBS information, and the location accuracy corresponding to the LBS application to obtain fuzzy location information. The invention can solve the technical problems of poor personalization, low efficiency, poor real-time performance and untrustworthy third-party dependence existing in the existing method.

Description

technical field [0001] The invention belongs to the field of computer security, and more specifically, the invention relates to a location privacy protection method and system based on granularity control. Background technique [0002] The rapid development of wireless communication and mobile database technology makes it possible for mobile users to query any information at any time and place. The rapid development of location detection devices (such as cellular phones, GPS, RFID, etc.) has led to a new research field - location-based services (LBSs), such as location-based store or restaurant (etc.) look-up, traffic reporting and location-based According to the data from iiMedia Consulting, as of the second quarter of 2012, the accumulative users of mobile phone LBS in my country reached 217 million. LBS has become an interesting and useful emerging industry in the mobile Internet. Location-based services require users to provide their own location information to the locat...
