Mitigating conformational bias in authentication systems

摘要

An authentication method and system to combat confirmation bias provides for an authentication system that upon matching an access request to a record for a given user in an authentication system further interrogates a set of secondary sources to determine that the individual requesting access is in fact the correct user.

1. A method of mitigating confirmational bias during authentication, the method comprising:
receiving from an input device a request for authentication of a user, the request including user identification information and access point information; comparing the user identification information with user identification records in an authentication database; upon the user identification information matching a user identification record in the authentication database:
retrieving a set of secondary records of secondary information of the user from a set of secondary sources;for each record of the set of secondary records calculating a score, the score indicative of a difference between the access point information and secondary information of the record;aggregating the score of each record of the set of secondary records to form an aggregated score;comparing the aggregated score to a predetermined value; andinitiating secondary authentication upon the aggregate score exceeding the predetermined value; and upon the user identification information not matching a user identification records in the authentication database, denying authentication of the user.
