Abstract

Systems, methods, devices, and computer programming products for NFC-enabled sharing of data files stored by networked computing resources, according to a variety of selectable criteria.

Claims

1. A method, performed by a near-field communication (NFC) enabled device, comprising:

using an NFC data transfer, authorizing sharing of a set of data files with a second NFC-enabled device;

acquiring at least one file to be shared with the second NFC-enabled device, and associating the at least one file with an identifier indicating that the file is eligible to be shared; and

uploading at least one file identified as eligible for sharing with the second NFC-enabled device to a networked storage resource, for storage in a shared folder accessible by the second NFC-enabled device.

2. The method of claim 1 wherein the identifier indicating that the file is eligible to be shared is determined based at least partly on data received from the second NFC-enabled device.

3. The method of claim 2 wherein the identifier comprises a reference enabling the networked storage resource to communicate with the second NFC-enabled device.

4. The method of claim 1, comprising transmitting to the second NFC-enabled device data representing an authorization for the second NFC-enabled device to access the at least one file from the shared folder.

5. The method of claim 1 comprising transmitting the file identified as eligible for sharing to the second NFC-enabled device over a communications network.

6. The method of claim 1 comprising, using a NFC data transfer, transmitting the file identified as eligible for sharing to the second NFC-enabled device.

7. The method of claim 1 comprising modifying a sharing eligibility criterion of the at least one file in the shared folder.

8. The method of claim 1 comprising associating a predetermined time limit during which the file identified as eligible for sharing is eligible for sharing with the second NFC-enabled device.

9. A method, performed by a networked storage resource, comprising:

receiving over a communications network, from a first NFC-enabled device, at least one data file, the data file associated with an identifier authorizing at least a second NFC-enabled device eligible to access the data file;

storing the at least one received data file in secure, persistent storage;

receiving over the communications network a request from at least the second NFC-enabled device for at least read access to the at least one stored data file; and

based at least partly on a comparison of the identifier with at least one access criterion, authorizing at least read access to the at least one stored data file by at least the second NFC-enabled device.

10. The method of claim 9, wherein the criterion corresponds to at least one of a location, a file type, a current time, an elapsed time, a personal identifier, and a device identifier.

11. The method of claim 9 wherein the storing step comprises grouping the at least one received data file in a shared folder accessible by the second NFC-enabled device according to the at least one access criterion.

12. The method of claim 11 comprising modifying sharing eligibility of the grouped data files in accordance with an access change request received from the first NFC-enabled device.

13. The method of claim 9 wherein the identifier is determined based at least partly on data received from the second NFC-enabled device.

14. The method of claim 13 wherein the request from at least the second NFC-enabled device comprises data from the first NFC-enabled device.

15. The method of claim 13 comprising initiating communication with the second NFC-enabled device over the communications network at least partly by using the identifier;

and transmitting the at least one stored file to the second NFC-enabled device.

16. The method of claim 13 comprising initiating communication with a second NFC networked storage resource associated with the second NFC-enabled device at least partly by using the identifier;

and transmitting the at least one stored file to the second networked storage resource.

17. The method of claim 9 comprising, after a predetermined time elapses from the receiving of the at least one data file from the first NFC-enabled device, transmitting a notification to the first NFC-enabled device to update the at least one access criterion of the at least one stored file.

18. A NFC-enabled device comprising:

a processor;

a medium or media including machine-readable instructions executable by the processor to;

use an NFC data interchange to authorize sharing of a set of data files with a second NFC-enabled device;

acquire at least one file to be shared with the second NFC-enabled device, and associate the at least one file with an identifier indicating that the file is eligible to be shared; and

upload at least one file identified as eligible for sharing with the second NFC-enabled device to a networked storage resource, for storage in a shared folder accessible by the second NFC-enabled device.

20. A networked storage resource comprising:

a processor;

a medium or media including machine-readable instructions executable by the processor to;

receive over a communications network, from a first NFC-enabled device, at least one data file, the data file associated with an identifier authorizing at least a second NFC-enabled device eligible to access the data file;

store the at least one received data file in secure, persistent storage;

receive over the communications network a request from at least the second NFC-enabled device for at least read access to the at least one stored data file; and

based at least partly on a comparison of the identifier with at least one access criterion, authorize at least read access to the at least one stored data file by at least the second NFC-enabled device.

19. The NFC-enabled device of claim 20 wherein the identifier indicating that the file is eligible to be shared is determined based at least partly on data received from the second NFC-enabled device;

and the machine-readable instructions executable by the processor to upload the identifier to the networked storage resource.

21. A computer program product having a non-transitory computer readable medium tangibly embodying computer executable code which, when executed by a processor of a NFC-enabled device, causes the NFC-enabled device to:

use an NFC data interchange to authorize sharing of a set of data files with a second NFC-enabled device;

acquire at least one file to be shared with the second NFC-enabled device, and associate the at least one file with an identifier indicating that the file is eligible to be shared; and

upload at least one file identified as eligible for sharing with the second NFC-enabled device to a networked storage resource, for storage in a shared folder accessible by the second NFC-enabled device.

22. A computer program product having a non-transitory computer readable medium tangibly embodying computer executable code which, when executed by a processor of a networked storage resource, causes the networked storage resource to:

receive over a communications network, from a first NFC-enabled device, at least one data file, the data file associated with an identifier authorizing at least a second NFC-enabled device eligible to access the data file;

store the at least one received data file in secure, persistent storage;

receive over the communications network a request from at least the second NFC-enabled device for at least read access to the at least one stored data file; and

based at least partly on a comparison of the identifier with at least one access criterion, authorize at least read access to the at least one stored data file by at least the second NFC-enabled device.
