Mobile App Security Framework via Segmented Analysis

The patent segments the security analysis process into multiple phases: static analysis phase, runtime analysis phase, and reporting phase. The analysis is divided into analyzing application code, identifying security policies, detecting violations, and generating reports. This segmentation allows the system to process different aspects of security analysis separately and efficiently, improving overall security coverage without proportionally increasing analysis time.

The patent performs preliminary static analysis of application code before runtime execution. Security policies are identified and security-critical regions are marked during the static analysis phase, so that during runtime analysis, the system can focus only on these pre-identified regions rather than analyzing entire application flows, significantly reducing runtime analysis time while maintaining comprehensive security coverage.

The patent introduces an intermediary security analysis system that acts as a mediator between the mobile application and the operating system. This intermediary layer handles security policy enforcement by intercepting system calls and application behaviors, analyzing them against defined security policies, and enforcing restrictions when violations are detected. This approach maintains security reliability while managing system complexity through a dedicated security layer rather than embedding complex enforcement logic throughout the entire system.

The patent implements feedback mechanisms where the security analysis system continuously monitors application behavior, compares it against security policies, and provides real-time feedback by blocking or alerting on policy violations. The system learns from analysis results and adjusts its monitoring focus, providing feedback loops that improve security enforcement effectiveness while maintaining manageable system complexity through adaptive rather than purely deterministic control.

The patent applies local quality by focusing detailed analysis only on security-critical regions of the application code that are identified during static analysis. Instead of uniformly analyzing all code paths with the same depth, the system concentrates processing resources on regions marked as potentially security-relevant, achieving high detection precision for security issues while maintaining overall processing speed by reducing analysis intensity in non-critical areas.

The patent employs partial action by performing comprehensive static analysis on all application code to identify security policies and critical regions, then performing more intensive runtime analysis only on the subset of code that is actually executed and identified as security-critical. This partial approach to runtime analysis maintains high detection precision for security vulnerabilities while avoiding the excessive processing that would result from analyzing entire application flows at full depth during runtime.
