Privacy Interface Invocation with Scenario-Based Access Checks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing client applications on mobile terminals are vulnerable to attacks that compromise user privacy data, as attackers can invoke privacy interfaces outside declared use scenarios, leading to unauthorized data theft.
Innovation Solution
Implement a method where client applications declare use scenarios for privacy interfaces during installation, and the operating system configures corresponding scenario information. Invocation requests are executed only when current scenario information matches the declared use scenario, thereby intercepting unauthorized requests.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If client applications are allowed to invoke privacy interfaces freely, then application functionality is improved, but user privacy security deteriorates
Solution Approach 1:
The patent applies preliminary action by requiring client applications to declare their intended use scenarios for privacy interfaces in advance, before actual invocation. The system configures scenario information based on these declarations and stores it for later verification. When an invocation request is made, the system checks whether the current scenario matches the pre-declared scenario, thereby preventing unauthorized access while allowing legitimate functionality.
2Object-affected harmful factors
If scenario verification is implemented for interface invocations, then privacy security is improved, but system complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the interface invocation process into distinct phases: scenario declaration during application installation, scenario configuration by the system, and scenario verification at invocation time. The scenario information is segmented into specific elements (current scenario and declared scenario) that are independently verified. This structured segmentation makes the security mechanism more manageable and less complex than a monolithic approach.
3Object-affected harmful factors
If unauthorized interface invocations are blocked, then privacy security is improved, but application usability deteriorates
Solution Approach 1:
The patent applies feedback by implementing a verification mechanism that compares the current scenario information with the pre-declared scenario information. When the scenarios match, the interface invocation is permitted; when they don't match, the invocation is blocked. This automated feedback loop ensures that legitimate applications can function normally while unauthorized invocations are prevented, maintaining usability for valid use cases while enhancing security.

AI summary
Embodiments of this specification provide computer-implemented methods, apparatuses, and computer-readable storage media for interface invocation request processing. In an example interface invocation request processing method, an invocation request for a first interface of an operating system is received from a client application, and the first interface is configured to obtain privacy data. First scenario information is obtained, where the first scenario information is description information of a use scenario of the first interface declared when the client application applies for an invocation permission of the first interface. Current scenario information of the client application is obtained. The invocation request is executed in response to at least that the current scenario information matches the first scenario information.
