Mobile Terminal Resource Access Control via Dynamic User Permission

The patent implements dynamic access control where the basic processing part selectively grants access rights to applications based on user permissions and resource types. Instead of a static prohibition, the system dynamically adjusts access levels, allowing applications to access confidential resources when authorized while maintaining protection when unauthorized. This resolves the contradiction by making the access control mechanism flexible rather than rigid.

The basic processing part acts as an intermediary between applications and confidential resources. It receives access requests from applications, evaluates them against security policies and user permissions, and selectively grants or denies access. This mediator role enables controlled access that protects personal information while allowing necessary application functionality, thus resolving the contradiction between security and convenience.

The patent implements local quality control by granting different access rights to different applications based on their specific needs and trust levels. Instead of uniform access control, each application receives tailored permissions appropriate to its function. This allows high-functionality applications to access necessary resources while limiting access for less trusted applications, thus enabling versatility while mitigating security risks.

The basic processing part serves as a security intermediary that filters and controls application access to confidential resources. It implements security checks, validates access requests, and prevents unauthorized operations. This intermediary layer enables applications to function with appropriate access rights while blocking security threats, thus achieving both versatility and security.
