Service Point Positioning for Variable-Speed User Authentication

The patent applies the dynamics principle by making the service point movable rather than fixed. The service point dynamically adjusts its position based on the detected movement speed of the user. When users move faster, the service point is positioned farther away; when users move slower, the service point is positioned closer. This dynamic adjustment ensures accurate service timing while adapting to individual user characteristics, resolving the contradiction between service timing accuracy and system complexity.

The patent applies the local quality principle by customizing the service point position for each user based on their individual movement characteristics. Instead of using a single fixed position for all users, the system detects each user's movement speed and positions the service point at an appropriate distance for that specific user. This localized adjustment ensures that both fast-moving and slow-moving users receive services at the optimal timing, resolving the contradiction between service delivery timing and adaptability to different movement speeds.

The patent applies the self-service principle by using the user's own movement characteristics as the basis for service point positioning. The system leverages the natural movement patterns that users exhibit as they approach the service area, rather than requiring complex external tracking infrastructure. By detecting and utilizing these inherent movement characteristics, the system achieves continuous authentication and accurate service timing while minimizing additional system complexity and data processing requirements.
