Abstract

In one embodiment, a device in a network receives data associated with a particular location. The device determines when the device is at the particular location by monitoring a local position of the device relative to the particular location. The device identifies a node in the network as being co-located with the device at the particular location. The device shares the data with the identified node based on the device and the node being co-located at the particular location.

First claim

What is claimed is:

1. A method comprising:
receiving, at a device in a network, data associated with a particular location;
determining, by the device, a timeframe when the device is at the particular location by monitoring a local position of the device relative to the particular location;
identifying, by the device, a node in the network as being co-located with the device at the particular location during the timeframe;
receiving, at the device, a query from the node that indicates one or more characteristics of the data;
matching, by the device, the indicated one or more characteristics of the data to the data; and
in response to the indicated one or more characteristics matching and the node being co-located during the time frame, sharing, by the device, the data with the identified node, wherein the node performs a local query on the shared data, and wherein the shared data is configured to restrict access to the data unless the local query includes one or more characteristics of the shared data.

2. The method as in claim 1 , wherein the one or more characteristics comprise an image.

3. The method as in claim 1 , wherein the particular location corresponds to a location at which the data was first generated.

4. The method as in claim 1 , further comprising:
detecting, by the device, that the device is outside of the particular location; and
preventing, by the device, all sharing of the data by the device when the device is outside of the particular location.

5. The method as in claim 1 , wherein preventing all sharing of the data by the device comprises deleting the data in response to detecting that the device is outside of the particular location.

6. The method as in claim 1 , wherein the method further comprises:
deleting, by the device, the data from the device on expiration of the timeframe.

7. An apparatus, comprising:
one or more network interfaces to communicate with a network;
a processor coupled to the one or more network interfaces and configured to execute one or more processes; and
a memory configured to store a process executable by the processor, the process when executed operable to:
receive data associated with a particular location;
determine a timeframe when the device is at the particular location by monitoring a local position of the device relative to the particular location;
identify a node in the network as being co-located with the device at the particular location during the timeframe;
receive a query from the node that indicates one or more characteristics of the data;
match the indicated one or more characteristics of the data to the data; and
in response to the indicated one or more characteristics matching and the node being co-located during the time frame, share the data with the identified node, wherein the node performs a local query on the shared data, and wherein the shared data is configured to restrict access to the data unless the local query includes one or more characteristics of the shared data.

8. The apparatus as in claim 7 , wherein the one or more characteristics comprise an image.

9. The apparatus as in claim 7 , wherein the particular location corresponds to a location at which the data was first generated.

10. The apparatus as in claim 7 , wherein the process when executed is further operable to: detect that the device is outside of the particular location; and prevent all sharing of the data by the device when the device is outside of the particular location.

11. The apparatus as in claim 7 wherein preventing all sharing of the data by the device comprises the data in response to detecting that the device is outside of the particular location.

12. The apparatus as in claim 7 , wherein the data is associated with a timeframe, and wherein the process when executed is further operable to delete the data from the device on expiration of the timeframe.

13. A tangible, non-transitory, computer-readable medium storing program instructions that cause a device in a network to execute a process comprising:
receiving, at the device, data associated with a particular location;
determining, by the device, a timeframe when the device is at the particular location by monitoring a local position of the device relative to the particular location;
identifying, by the device, a node in the network as being co-located with the device at the particular location during the timeframe;
receiving, by the device, a query from the node that indicates one or more characteristics of the data;
matching, by the device, the indicated one or more characteristics of the data to the data; and
in response to the indicated one or more characteristics matching and the node being co-located during the time frame, sharing, by the device, the data with the identified node based on the device and the node being co-located at the particular location during the timeframe.

14. The computer-readable medium as in claim 13 , wherein the particular location corresponds to a location at which the data was first generated.
