Embodiment Construction

[0022]The technical scheme of the present invention is based on the Android platform, and software technology can be used to realize automatic operation during specific implementation. For the existing processes and functions involved, please refer to the corresponding documents.

[0023] The following provides a detailed description of the technical solution of the present invention in conjunction with the drawings and embodiments.

[0024] like figure 1 As shown, in the general application process request location service communication process, the Application (application) first sends a request datagram to access the Location (location) service to the ServiceManager (service management) process, that is, 1. Request access to the service in the figure ;The ServiceManager process returns the access entry of the Location service, that is, 2. Return the location provider entry in the figure; then the Application requests access to the System_server according to the entry, that ...

Abstract

The invention belongs to the technical field of location privacy protection and provides an Android platform based GPS (global positioning system) data intercepting control method. Without impacting Android system performances, an own location service monitoring module is inserted into a system_server process to achieve intercepting control of GPS data. For achieving GPS data intercepting control of an Android platform, the method includes the two steps of firstly, finding an entry address of an ioctl function during operation of the system_server process, and secondly, loading the own monitoring module at the entry address of the ioctl function in the system_server process so that GPS datagram is intercepted on the bottom layer.

Description

technical field [0001] The invention belongs to the technical field of location privacy protection, and in particular relates to a GPS data interception control method based on an Android platform. Background technique [0002] Location privacy protection is an important aspect of LBS (Location-Based Services), and one of the key technologies for users to obtain QoS (Quality of Service), which directly affects whether users install and normally use location-based service applications. This is discussed in almost all technical literature and research papers related to LBS.
