Identity Authentication Based on Two-Beam Interference


A two-factor identity authentication method on the basis of two-beam interference was presented. While verifying a user’s identity, a specific “phase key” as well as a corresponding “phase lock” are both mandatory required for a successful authentication. Note that this scheme can not only check the legality of the users, but also verify their identity levels so as to grant them hierarchical access permissions to various resources of the protected systems or organizations. The authentication process is straightforward and could be implemented by a hybrid optic-electrical system. However, the system designing procedure involves an iterative Modified Phase Retrieval Algorithm (MPRA) and can only be achieved by digital means. Theoretical analysis and simulations both validate the effectiveness of our method.
