Runtime Advertising Code Scanning for Mobile Security

The patent introduces an intermediary scanning mechanism that sits between the advertising code delivery and execution. The scan function intercepts advertising code, scans it for malicious content using pattern matching and heuristics, and only allows safe code to execute. This mediator resolves the contradiction by enabling advertising display while blocking malicious content through the scanning intermediary layer.

The scanning mechanism applies partial action by not scanning all advertising code equally. Instead, it uses lightweight pattern matching for common malicious signatures first, then applies more resource-intensive heuristics only when needed. This selective scanning approach maintains security while minimizing processing time and resource consumption for benign advertising code.

The patent implements local quality by making the security scanning capability optional and configurable. Developers can choose to include or exclude the scan function based on their specific security needs. The program code is implanted in a modular way that allows selective activation, so devices that require high security get full protection while others can use minimal resources.

The patent uses nesting by embedding the scanning logic within the advertising code execution flow. The wrap function nests the scan call inside the existing advertising rendering pipeline, so the scanning capability is contained within the existing code structure rather than adding external complexity. This nested approach maintains detection precision while minimizing overall code complexity.
