Abstract: A method for managing third party application program access to user information via a particular native application program interface (API) is provided. The method includes providing a wrapped native API including a wrapper library and inspecting a third party application program for the presence of the wrapper library in an unmodified form. The application program is inspected to identify API calls. An identified API call to a circumventing API is instrumented by wrapping the circumventing API to generate a wrapped non-circumventing API and modifying the third party application program to redirect the identified API call from the circumventing API to the wrapped non-circumventing API. A request for a permission to access user information is received from the third party application program via the wrapper library executed on a user device.

Abstract: A computer-implemented navigation method for implementation during a navigation routine for directing a user is provided. The navigation method comprises generating a navigation route. GPS signals are received and position fixes are derived from the GPS signals. The position fixes are stored and compared with the navigation route. A threshold value is determined based on the comparison of the position fixes with the navigation route. An updated navigation route is generated based on the plurality of position fixes distanced from the navigation route a distance greater than the threshold value and an updated navigation route is not generating based on the plurality of position fixes distanced from the navigation route a distance not greater than the threshold value. A mobile device for performing a navigation procedure is also provided.

Abstract: A computer-implemented mobile device calling method is provided. The method includes detecting initiation of a communication between a first mobile device and a second mobile device and determining a current location of the first mobile device in response to initiation of the communication between the first mobile device and the second mobile device. The method further includes transmitting the current location of the first mobile device to the second mobile device in response to initiation of the communication between the first mobile device and the second mobile device. A system for managing distribution of location information between mobile devices is further provided.
