Abstract—User authentication (UA) is the first and significant step for users before accessing information services. The most popular and typical approach to UA is based on username/password to identify and authenticate users. The traditional approach is neither convenient and nor reliable. In this paper, a new approach based on optical spectrum is proposed. The authentication code is generated according to optical spectrum to make password secure. Besides, the generated code is renewed after the code has been authenticated. Such a one-time password effectively protects systems from the malicious copy and skimming attacks. A numeric analysis illustrate that the proposed approach have lower crack probability than iris and fingerprint authentication. The proposed UA is realized on an Arduino Nano Board to verify the feasibility. The results illustrate the UA proposed by this study. Have potential to surpass the existing user authentication technology at security. And it is reliable, low-cost and feasible system design.
