Abstract:
1. A computer-implemented method of authenticating a user, the method comprising: generating at a validation server a unique user ID number and matching encryption key corresponding to the user; transmitting the unique user ID number and matching encryption key to a user device; generating a temporary access code based on the encryption key on the user device; providing the unique user ID number and temporary access code to at least one organization server adapted to run on at least one computer separately maintained by independent host organizations; transmitting the unique user ID number and temporary access code from the at least one organization server to the validation server; generating the encryption key matching the unique user ID number and generating a second code on the validation server in the same fashion as the temporary access code was generated; performing on the validation server a verification of the unique user ID number and temporary access code by comparing the second code and the temporary access code to obtain a validation result; transmitting the validation result to the at least one organization server; and authenticating the user at the at least one organization based on the validation result, wherein the validation server is adapted to run on at least one computer that is maintained by a first organization that is independent and separate from the independent host organizations and their respective organization servers, and wherein the unique user ID is non-secret and shared with each of the independent host organizations.
