Verification of a person identifier received online

Abstract

A system and method for verification of a person identifier received online is described. The method includes receiving a request for verifying a person identifier (PI1); and estimating whether (a) PI1 identifies the same person as another person identifier (PI2), (b) sender of PI1 is the same person as sender of PI2, and (c) PI2 identifies the sender of PI2.

         2 . A system of verifying an online user comprising:
 a receiver executable by a processor and configured to receive a first person identifier for the online user; and   a verification estimator configured to verify the online user in response to a determination that the first person identifier and a second person identifier satisfies a same person condition, wherein the same person condition is satisfied if a same person condition strength level is evaluated as exceeding a first threshold, a determination that a sender of the first person identifier and a sender of the second person identifier satisfy a same sender condition, wherein the same sender condition is satisfied if a same sender condition strength level is evaluated as exceeding a second threshold, and a determination that a second person identifier identifies the sender of the second person identifier.   
     
     
         3 . The system of  claim 1 , wherein the same person condition strength level is evaluated based on whether the first person identifier and the second person identifier include substantially similar portions. 
     
     
         4 . The system of  claim 1 , wherein the same person condition strength level is evaluated based on whether the first person identifier and the second person identifier are verified against encrypted person identifier information stored in a user device, the encrypted person identifier information being accessed upon request to an encrypting authority. 
     
     
         5 . The system of  claim 1 , wherein the same person condition strength level is evaluated based on whether the first person identifier and the second person identifier include geographically proximate geographical parameters. 
     
     
         6 . The system of  claim 1 , wherein the same person condition strength level is evaluated based on whether the first person identifier and the second person identifier have a respective same person relation with a third person identifier. 
     
     
         7 . The system of  claim 1 , wherein the same sender condition strength level is evaluated based on whether there is relation between a reliable network address of a first sender of a first message and a reliable network address of a second sender of a second message. 
     
     
         8 . The system of  claim 1 , wherein the same sender condition strength level is evaluated based on whether a first secret known to a first sender of a first message and a second secret contained in a second message are derivatives of a common secret. 
     
     
         9 . The system of  claim 1 , wherein the same sender condition strength level is evaluated based on whether each of a first message and a second message has a respective same sender relation with a third message. 
     
     
         10 . A method of verifying an online user comprising:
 receiving a first person identifier for the online user; and   verifying the online user in response to a determination that the first person identifier and a second person identifier satisfies a same person condition, wherein the same person condition is satisfied if a same person condition strength level is evaluated as exceeding a first threshold, a determination that a sender of the first person identifier and a sender of the second person identifier satisfy a same sender condition, wherein the same sender condition is satisfied if a same sender condition strength level is evaluated as exceeding a second threshold, and a determination that a second person identifier identifies the sender of the second person identifier.   
     
     
         11 . The method of  claim 9 , wherein the same person condition strength level is evaluated based on whether the first person identifier and the second person identifier include substantially similar portions. 
     
     
         12 . The method of  claim 9 , wherein the same person condition strength level is evaluated based on whether the first person identifier and the second person identifier are verified against encrypted person identifier information stored in a user device, the encrypted person identifier information being accessed upon request to an encrypting authority. 
     
     
         13 . The method of  claim 9 , wherein the same person condition strength level is evaluated based on whether the first person identifier and the second person identifier include geographically proximate geographical parameters. 
     
     
         14 . The method of  claim 9 , wherein the same person condition strength level is evaluated based on whether the first person identifier and the second person identifier have a respective same person relation with a third person identifier. 
     
     
         15 . The method of  claim 9 , wherein the same sender condition strength level is evaluated based on whether there is relation between a reliable network address of a first sender of a first message and a reliable network address of a second sender of a second message. 
     
     
         16 . The method of  claim 9 , wherein the same sender condition strength level is evaluated based on whether a first secret known to a first sender of a first message and a second secret contained in a second message are derivatives of a common secret. 
     
     
         17 . The method of  claim 9 , wherein the same sender condition strength level is evaluated based on whether each of a first message and a second message has a respective same sender relation with a third message. 
     
     
         18 . A non-transitory machine-readable storage medium comprising instructions, which when implemented by one or more machines, cause the one or more machines to perform the following operations:
 receiving a first person identifier for an online user; and   verifying the online user in response to a determination that the first person identifier and a second person identifier satisfies a same person condition, wherein the same person condition is satisfied if a same person condition strength level is evaluated as exceeding a first threshold, a determination that a sender of the first person identifier and a sender of the second person identifier satisfy a same sender condition, wherein the same sender condition is satisfied if a same sender condition strength level is evaluated as exceeding a second threshold, and a determination that a second person identifier identifies the sender of the second person identifier.   
     
     
         19 . The non-transitory machine-readable storage medium of  claim 17 , wherein the same person condition strength level is evaluated based on whether the first person identifier and the second person identifier include substantially similar portions. 
     
     
         20 . The non-transitory machine-readable storage medium of  claim 17 , wherein the same person condition strength level is evaluated based on whether the first person identifier and the second person identifier are verified against encrypted person identifier information stored in a user device, the encrypted person identifier information being accessed upon request to an encrypting authority. 
     
     
         21 . The non-transitory machine-readable storage medium of  claim 17 , wherein the same person condition strength level is evaluated based on whether the first person identifier and the second person identifier include geographically proximate geographical parameters.
