System Architecture Design for Spoofing Detection Based on Baseband Information

This paper evaluates the performance of two anti-spoofing algorithms, studies the performance boundary of anti-spoofing technology under multiple parameters, verifies its reliability and effectiveness in the face of multiple spoofing attack ways, and provides a judgment basis for scheme selection. Moreover, combining the complementarity of advantages of different spoofing detection technologies, the detection probability in joint detection scenarios is calculated, it provides effective support for various spoofing scenarios. This paper then proposes an anti-spoofing system architecture based on baseband information. The architecture utilizes multi-dimensional and multi-feature signal analysis, and combines various spoofing parameters using specific group strategies, so as to obtain a more comprehensive reference for detection effects.
