Abstract

A method and user device for limiting a time for which location data sharing is enabled for a user device of a data sharing group, the data sharing group comprising at least two user devices inclusive of the user device, each user device of the data sharing group configured to store data shared by user devices of the data sharing group on the respective user device and to maintain a list of the user devices in the data sharing group. The method comprises receiving an instruction through a user interface on the user device indicating that location data sharing is to be enabled for a limited time period after which location sharing is to be disabled, obtaining location data for the user device during the limited time period; and sending the location data to at least one other user device of the sharing group during the limited time period.

Claims

1. A user device comprising:

an output interface for transmitting data to at least one other user device of a data sharing group, the data sharing group comprising at least two user devices inclusive of the user device, each user device of the data sharing group configured to store data shared by user devices of the data sharing group on the respective user device and to maintain a list of the user devices in the data sharing group;

a user interface, configured to receive an instruction to enable location data sharing for a limited time period after which location sharing is to be disabled; and

a location sharing module configured to, during the limited time period, provide location data for the user device to the output interface to be transmitted to the at least one other user device of the data sharing group.

2. The user device according to claim 1, further comprising a memory for storing data shared by the user devices of the data sharing group.

3. The user device according to claim 1, further comprising an input interface for receiving data shared by the user devices of the data sharing group.

4. The user device according to claim 1, wherein location sharing module is configured to commence providing the location data for the user device to the output interface upon receipt of the instruction.

5. The user device according to claim 1, further comprising a location determination system from which the location sharing module receives the location data.

6. The user device according to claim 5, wherein the location determination system comprises a GPS (Global Positioning System) receiver.

7. The user device according to claim 1, wherein the location sharing module is further configured to instruct a location determination system to turn off after the limited time period.

8. The user device according to claim 1, further comprising a timer configured to track the limited time period.

9. The user device according to claim 1, wherein the user device is a mobile device.

10. A method for limiting a time for which location data sharing is enabled for a user device of a data sharing group, the data sharing group comprising at least two user devices inclusive of the user device, each user device of the data sharing group configured to store data shared by user devices of the data sharing group on the respective user device and to maintain a list of the user devices in the data sharing group, the method comprising:

receiving an instruction through a user interface on the user device indicating that location data sharing is to be enabled for a limited time period after which location sharing is to be disabled;

obtaining location data for the user device during the limited time period; and

transmitting the location data to at least one other user device of the sharing group during the limited time period.

11. The method according to claim 10, wherein obtaining location data for the user device comprises receiving a current location from GPS data in the user device.

12. The method according to claim 10, further comprising turning off a GPS receiver in the user device after the limited time period expires.

13. The method according to claim 10, further comprising creating a notification indicating that the location data sharing has been disabled after the limited time period expires.

14. The method according to claim 10, further comprising enabling location sharing according to a pre-established schedule after the limited time period expires.

15. A computer readable medium having computer executable instructions stored thereon, that when executed cause a processor to implement a method for limiting a time for which location data sharing for a user device of a data sharing group is enabled, the data sharing group comprising at least two user devices inclusive of the user device, each user device of the data sharing group configured to store data shared by user devices of the data sharing group on the respective user device and to maintain a list of the user devices in the data sharing group, and the method comprising:

receiving an instruction indicating that location data sharing is to be enabled for a limited time period after which location sharing is to be disabled;

obtaining location data for the user device; and

instructing an output interface to transmit the location data to at least one other user device of the data sharing group during the time limited period.

16. The computer readable medium of claim 15, wherein the method further comprises presenting options on a user interface for selecting time periods for the limited time period.

17. The computer readable medium of claim 16, wherein the options include one or more lengths of time starting from a present time.

18. The computer readable medium of claim 16, wherein the options include one or more recurring time periods.

19. The computer readable medium of claim 16, wherein the options are presented in the form of a calendar, from which the user can select one or more time periods.

20. The computer readable medium of claim 15, wherein the location data is obtained from GPS (Global Positioning System) data.
