Adaptive Identity Authentication for Mobile Terminals

The patent applies local quality by differentiating authentication accuracy requirements according to service security levels. High-security services (e.g., payment) use high-accuracy authentication (first authentication with strict matching), while low-security services (e.g., messaging) use lower-accuracy authentication (second authentication with relaxed matching). This resolves the contradiction by matching authentication rigor to actual service needs, improving efficiency without compromising security where required.

The patent changes the parameter of authentication accuracy based on service security levels. It introduces multiple authentication modes with different accuracy thresholds and validity durations. The terminal adjusts authentication parameters dynamically: for high-security services, it uses stricter matching criteria and shorter validity periods; for low-security services, it uses more lenient criteria and longer validity periods, thereby resolving the efficiency-security trade-off.

The patent introduces dynamic authentication where the required authentication accuracy and frequency adapt based on service security levels and risk assessments. For low-security services, the system dynamically reduces authentication burden by using pre-validated credentials with extended validity. For high-security services, it dynamically increases scrutiny. This dynamic adjustment resolves the contradiction by making authentication adaptive rather than static.

The patent applies partial action by performing only the necessary level of authentication for each service. Instead of always executing full high-accuracy authentication, it performs partial verification for low-security services using previously validated biometric data, reserving full authentication for high-security operations. This reduces user burden while maintaining adequate security.

The patent segments the authentication system into multiple levels: first authentication for high-security services and second authentication for low-security services. Each segment has its own accuracy requirements, validity durations, and verification processes. This segmentation resolves the contradiction by organizing complexity into manageable, service-specific modules rather than a monolithic system.

The patent creates a universal authentication framework that handles multiple service types through a common architecture. The terminal maintains a unified credential storage and authentication management system that can serve both high-security and low-security services, adapting its behavior based on service requirements. This multi-functionality resolves the contradiction by providing service-specific authentication within a single integrated system.
