Abstract

The invention discloses a location information sharing method and device in an LBS. The method includes: receiving the sharer's location information sent by the sharer's terminal, recording the receiving time as the first time; receiving a request message from the requester's terminal requesting to obtain the sharer's location information, and recording the time of receiving the request message as the second time Time; calculate the time difference between the second time and the first time; obtain the first scrambling amplitude value according to the size of the time difference, the smaller the time difference, the larger the first scrambling amplitude value, and the larger the time difference , the smaller the first scrambling amplitude value; use the first scrambling amplitude value to scramble the sharer's location information; send the sharer's location information after the scrambling operation to the requester terminal, through the technical solution provided by the present invention , realizing flexible and dynamic scrambling of the shared location information, reducing the privacy leakage caused by sharing the location information, and providing privacy protection for the location information shared by users.

Description

technical field [0001] The present invention relates to the communication field, in particular to a location information sharing method and device in an LBS. Background technique [0002] Applications based on Location Based Service (Location Based Service, LBS) are more and more widely used. For example, in an LBS-based social networking service (Social Networking Services, SNS) business, users use the service to share their own location information and also obtain other users' location information. [0003] With the continuous development of mobile communication technology and positioning technology. LBS can provide high-precision, high-timeliness location information for applications. However, since the location information provided by the LBS is related to the user's location, it may pose a threat to the user's privacy. Especially in the above-mentioned LBS-based social applications, there is even a problem that the obtained location information is used to endanger th...
