Abstract

Systems and methods are provided for social networks that can verify that enrolled users are not misrepresenting facts about themselves such as age and gender. Verification can be performed, for example, by reference to biometric templates stored during the user enrollment process. The biometric templates can also be used to authenticate users logging into the social network to prevent user impersonation. The ability of some users to communicate to other users of the social network can be limited to only certified users, and even to those certified users that match a criterion, such as gender or age.

Claims

1. A social network system comprising:

enrollment logic comprising a first microprocessor and configured to associate users with user IDs,

store a plurality of prompts in association with each such user ID,

store a plurality of biometric templates each in association with one of the plurality of prompts,

compare a biometric template of the plurality of biometric templates of a first user against a plurality of biometric templates of barred users, and

deny enrollment to the first user based on a match between the biometric template of the first user and one of the plurality of biometric templates of barred users; and

authentication logic comprising a second microprocessor and configured to authenticate a claimant as a second user by

receiving a claimant target,

sending a prompt from the plurality of prompts,

receiving a biometric response to the prompt, and

determining a match between the biometric response and a biometric template associated with the prompt; and

further configured to receive a request from a third user of the social network to authenticate the second user of the social network; and

to send to the third user at least a portion of the biometric response of the second user, or at least a portion of the biometric template of the second user.

2. A method comprising:

associating users of a social network with user IDs;

storing a plurality of prompts in association with each such user ID;

storing each such user ID in association with a biometric template of the respective user;

comparing a biometric template of a first user against a plurality of biometric templates of barred users, and

denying enrollment to the first user based on a match between the biometric template of the first user and one of the plurality of biometric templates of barred users;

providing a prompt from the plurality of prompts to a second user and storing a biometric response of the second user thereto in association with the user ID of the second user;

receiving a request from a third user of the social network to authenticate the second user of the social network; and

sending to the third user at least a portion of the biometric response of the second user, or at least a portion of the biometric template of the second user.

3. The method of claim 2 wherein the steps of providing the prompt and storing the biometric response of the second user are steps that are performed to log into the second user'"'"'s social network account.

4. The method of claim 2 wherein the step of receiving the request from the third user is performed after the step of storing the biometric response of the second user.
