Smart Lock Authentication Using Distance Trend and Environment Matching

The system performs preliminary actions by monitoring distance change trends and comparing environment parameters before enabling identity authentication. The terminal device continuously monitors its distance from the smart lock and compares environment parameters (light, temperature, humidity) in advance, only enabling authentication when approaching trends are detected and parameters match, thereby preventing relay attacks before they can succeed while maintaining seamless user experience

The system implements feedback mechanisms by continuously monitoring distance changes and environment parameters, then using this information to dynamically control authentication enablement. The terminal device receives feedback from distance monitoring modules and environment sensors, processes this information to determine authentication eligibility, and adjusts authentication state accordingly, creating a closed-loop security system that prevents relay attacks while maintaining ease of operation

The system applies universality by utilizing the terminal device's existing multi-functional capabilities - using the same device for communication, distance monitoring, and environment parameter detection. The terminal device leverages its built-in sensors (light, temperature, humidity sensors) and communication modules to perform multiple security functions simultaneously, avoiding the need for separate dedicated hardware components and thereby limiting complexity increase

The system implements self-service by having the terminal device autonomously perform distance monitoring and environment parameter comparison without requiring additional external monitoring equipment. The terminal device uses its own built-in sensors and processing capabilities to evaluate authentication conditions and make decisions, eliminating the need for complex external monitoring infrastructure and keeping device complexity manageable
