Techniques for managing discussion sharing on a mobile platform

1. A computer-implemented method comprising:

retrieving an image from a user of a social networking system, the user having an associated user account and user profile on the social networking system, the image containing a discussions invitation ticket comprising a machine-readable invitation token configured to provide the user having the associated user account and user profile access to one or more discussion groups associated with the machine-readable invitation token;

recognizing the machine-readable invitation token in the image;

decoding the machine-readable invitation token; and

providing access to the user to the one or more discussion forums based on the decoding of the machine-readable invitation token.

2. The computer implemented method of claim 1 , wherein retrieving the image further comprises:

scanning, automatically, an image datastore on a mobile device associated with the user to recognize at least one image comprising the discussions invitation ticket.

3. The computer implemented method of claim 1 , wherein the invitation ticket further comprises an invitation signature comprising a geometric shape, substantially enclosing at least the invitation token.

4. The computer-implemented method of claim 1 , further comprising:

capturing an image, the captured image comprising the discussions invitation ticket; and

storing the captured image in an image datastore on a mobile device associated with the user.

5. The computer-implemented method of claim 1 , further comprising:

rendering a ticket image comprising a token configured to authorize access to a discussion forums or groups to a second user in the social networking system having an associated user account and user profile; and

providing the ticket image to a different mobile device associated with the second user to enable access to the discussion forums or groups by the second user.

6. At least one non-transitory computer-readable storage medium comprising instructions that, when executed, cause a system to:

retrieve an image from a user of a social networking system, the user having an associated user account and user profile on the social networking system, the image containing a discussions invitation ticket comprising a machine-readable invitation token configured to provide the user having the associated user account and user profile access to one or more discussion groups associated with the machine-readable invitation token;

recognize the machine-readable invitation token in the image;

decode the machine-readable invitation token; and

provide access to the user to the one or more discussion forums based on the decoding of the machine-readable invitation token.

7. The non-transitory computer-readable storage medium of claim 6 , wherein the instructions to retrieve the image, when executed, further cause the system to:

scan, automatically, the image datastore on a mobile device associated with the user to recognize at least one image comprising the discussions invitation ticket.

8. The non-transitory computer-readable storage medium of claim 6 , wherein the instructions, when executed, further cause the system to:

capture an image, the captured image comprising the discussions invitation ticket; and

store the captured image in an image datastore on a mobile device associated with the user.

9. The non-transitory computer-readable storage medium of claim 6 , wherein the instructions, when executed, further cause the system to:

render a ticket image comprising a token configured to enable access to a discussion forum or group to a second user in the social networking system having an associated user account and user profile; and

provide the ticket image to a different mobile device associated with the second user to enable access to the discussion forum or group by the second user.

10. An apparatus, comprising:

a processor circuit;

memory operatively coupled to the processor circuit, the memory to store a mobile discussions application for execution by the processor circuit, the mobile discussions application configured to:

retrieve an image from a user of a social networking system, the user having an associated user account and user profile on the social networking system, the image containing a discussions invitation ticket comprising:

a machine-readable invitation token configured to provide the user having the associated user account and user profile access to one or more discussion groups associated with the machine-readable invitation token; and

an invitation signature comprising a geometric shape enclosing the machine-readable invitation token;

recognize the machine-readable invitation token in the image;

decode the machine-readable invitation token; and

provide access to the user to the one or more discussion forums based on the decoding of the machine-readable invitation token.

11. The apparatus of claim 10 , wherein the discussions invitation ticket is recognized in at least one image in an image datastore on a mobile device associated with the user.

12. The apparatus of claim 11 , wherein retrieving the image comprises scanning, automatically, the image datastore to recognize at least one image comprising the discussions invitation ticket.

13. The apparatus of claim 12 , wherein the mobile discussions application is further configured to scan, automatically, the image datastore to identify at least one image comprising a discussions invitation ticket, in response to a transition of an execution state associated with the mobile discussions application from a non-foreground state to a foreground state.

14. The apparatus of claim 11 , wherein the at least one image comprises at least one discussions invitation ticket, and the at least one image is captured and stored in an image datastore on the mobile device by a non-mobile discussions application.

15. The apparatus of claim 11 , the mobile discussions application further configured to invite a different user having an associated user account and user profile on a different mobile device to access a particular discussion forum or group in the social networking system based at least partially on an image comprising an invitation token configured to enable access to the particular discussion forum or group.
