Claim 14:
15. A system comprising:
a processor; and
a non-transitory computer-readable storage device comprising instructions that are executable by the processor to cause the system to perform operations comprising:
maintaining, at an authentication system, a data repository of reference user authentication data associated with a plurality of users;
receiving, at the authentication system, distorted user information as the reference user authentication data associated with a user of the plurality of users generated at a user computing device by applying a distortion function to user information of the user obtained by the user computing device associated with the user, wherein the distortion function is unique to the user computing device;
obtaining, at the authentication system from a secure storage system via a network, an authentication request for authenticating the user from the plurality of users, wherein the authentication request is submitted to the secure storage system by an access control system;
responsive to obtaining the authentication request, generating and submitting, by the authentication system, authentication inquiries to the secure storage system, wherein the authentication inquiries are retrievable from the secure storage system by the user computing device associated with the user;
receiving, at the authentication system from the secure storage system, responses to the authentication inquiries generated by the user computing device;
generating, at the authentication system, authentication results based on the responses to the authentication inquiries and the reference user authentication data associated with the user; and
transmitting, from the authentication system, the authentication results to the secure storage system over the network that is accessible by the access control system, wherein the authentication results are usable to control an access of the user computing device to a resource.
