Abstract

In one embodiment, a computing device of a social-networking system may receive from a computing device of a first user of the social-networking system information acquired by the computing device of the first user from a tag associated with a second user of the social-networking system. The tag may encode a time stamp, a signature, and a social action on the social-networking system. The computing device of the social-networking system may verify the signature and, if the signature is verified, then initiate the social action.

Claims

1. A method comprising:

by a computing device of a social-networking system, receiving from a computing device of a first user of the social-networking system information acquired by the computing device of the first user from a tag associated with a second user of the social-networking system, the tag encoding and the information comprising a time stamp, a signature, and a social action on the social-networking system, the social-networking system comprising a graph that comprises a plurality of nodes and edges connecting the nodes, at least one node in the graph corresponding to the first user, at least one node in the graph corresponding to the second user;

by the computing device of the social-networking system, verifying the signature; and

by the computing device of the social-networking system, if the signature is verified then initiating the social action, the social action as initiated being associated with at least one node in the graph corresponding to the first user and at least one node in the graph corresponding to the second user.

2. The method of claim 1, wherein the tag comprises a Quick Response (QR) code, a Near Field Communication (NFC) tag, or a radio-frequency identification (RFID) tag.

3. The method of claim 1, wherein initiating the social action comprises causing a message to be sent to the computing device of the first user corresponding to the social action.

4. The method of claim 1, wherein the signature is generated based least in part on the time stamp and a social-networking-system access token of the second user.

5. The method of claim 4, wherein the signature is generated with Secure Hash Algorithm 1 (SHA 1).

6. The method of claim 1, wherein the tag further encodes a Uniform Resource Locator (URL).

7. The method of claim 6, wherein the computing device of the first user sends the information to the URL using Hypertext Transfer Protocol Secure (HTTPS) protocol.

8. The method of claim 1, wherein the social action comprises creating an edge to or from at least one node in the graph corresponding to the first user or at least one node in the graph corresponding to the second user.

9. The method of claim 1, wherein the social action comprises generating a list of nodes connected by edges to at least one node in the graph corresponding to the first user or at least one node in the graph corresponding to the second user.

10. One or more computer-readable non-transitory storage media embodying software that is operable when executed by a computing device to:

receive from a computing device of a first user of a social-networking system information acquired by the computing device of the first user from a tag associated with a second user of the social-networking system, the tag encoding and the information comprising a time stamp, a signature, and a social action on the social-networking system, the social-networking system comprising a graph that comprises a plurality of nodes and edges connecting the nodes, at least one node in the graph corresponding to the first user, at least one node in the graph corresponding to the second user;

verify the signature; and

if the signature is verified then initiate the social action, the social action as initiated being associated with at least one node in the graph corresponding to the first user and at least one node in the graph corresponding to the second user.

11. The media of claim 10, wherein the tag comprises a Quick Response (QR) code, a Near Field Communication (NFC) tag, or a radio-frequency identification (RFID) tag.

12. The media of claim 10, wherein, to initiate the social action, the software is operable when executed by the computing device to cause a message to be sent to the computing device of the first user corresponding to the social action.

13. The media of claim 10, wherein the signature is generated based least in part on the time stamp and a social-networking-system access token of the second user.

14. The media of claim 13, wherein the signature is generated with Secure Hash Algorithm 1 (SHA 1).

15. The media of claim 10, wherein the tag further encodes a Uniform Resource Locator (URL).

16. The media of claim 15, wherein the computing device of the first user sends the information to the URL using Hypertext Transfer Protocol Secure (HTTPS) protocol.

17. The media of claim 10, wherein the social action comprises creating an edge to or from at least one node in the graph corresponding to the first user or at least one node in the graph corresponding to the second user.

18. The media of claim 10, wherein the social action comprises generating a list of nodes connected by edges to at least one node in the graph corresponding to the first user or at least one node in the graph corresponding to the second user.

20. The system of claim 10, wherein the tag comprises a Quick Response (QR) code, a Near Field Communication (NFC) tag, or a radio-frequency identification (RFID) tag.

19. A system comprising:

one or more processors; and

a memory coupled to the processors comprising instructions executed by the processors, the processors being operable when executing the instructions to;

receive from a computing device of a first user of a social-networking system information acquired by the computing device of the first user from a tag associated with a second user of the social-networking system, the tag encoding and the information comprising a time stamp, a signature, and a social action on the social-networking system, the social-networking system comprising a graph that comprises a plurality of nodes and edges connecting the nodes, at least one node in the graph corresponding to the first user, at least one node in the graph corresponding to the second user;

verify the signature; and

if the signature is verified then initiate the social action, the social action as initiated being associated with at least one node in the graph corresponding to the first user and at least one node in the graph corresponding to the second user.
