Ad Gateway Malware Filtering via Signature Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile communication devices are vulnerable to malware infiltration through spoofed mobile advertisements, which can lead to financial losses and privacy threats, as existing security measures are inadequate in filtering out malicious content.
Innovation Solution
A system and method that utilize a mobile advertisement filtering application to analyze advertisements for signatures such as brand identity, color scheme, and font type, and block transmission of malicious ads by matching these signatures with predefined rules stored in a data store, thereby preventing malware from reaching mobile devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If mobile advertisements are transmitted to mobile communication devices, then advertisement revenue is generated, but mobile devices become vulnerable to malware infiltration
Solution Approach 1:
The patent introduces an advertisement gateway server as an intermediary component between the advertisement source and mobile devices. This gateway server acts as a mediator that receives advertisements, analyzes them for malicious content using filtering applications, and selectively blocks or transmits advertisements based on security rules, thus protecting devices while maintaining revenue streams
Solution Approach 2:
The system performs preliminary security analysis of advertisements before they reach mobile devices. The filtering application pre-processes incoming advertisements by analyzing their signatures and comparing them against known malware patterns in the rules data store, blocking malicious content in advance while allowing legitimate advertisements to pass through
2Reliability
If security filtering is applied to mobile advertisements, then malware infiltration is reduced, but advertisement transmission complexity increases
Solution Approach 1:
The security filtering system is segmented into distinct functional components: an advertisement gateway server that receives and processes advertisements, filtering applications that perform security analysis, and a rules data store that contains security signatures. This segmentation allows each component to specialize in specific tasks, improving security effectiveness while managing system complexity through modular design
Solution Approach 2:
The advertisement gateway server serves as an intermediary that centralizes the filtering logic and rules management, preventing the need for complex filtering mechanisms to be distributed across multiple devices. This centralized approach simplifies the overall system architecture while maintaining robust security protection

AI summary
A method of thwarting infiltration of malware onto a mobile communication device. The method comprises a filtering application executing on an ad gateway server computer analyzing a mobile advertisement by to determine a signature of the mobile advertisement, where the signature comprises at least one of a brand identity, a color scheme, a reference image, and a font type, searching a rules data store using the signature of the mobile advertisement as a search key to obtain a first rule, and identifying a first mobile presentation context in the first rule. The method further comprises the filtering application determining that a mobile presentation context of a mobile communication device to which the mobile advertisement is directed by matches the first mobile presentation context and the filtering application blocking transmission of the mobile advertisement from the ad gateway server to the mobile communication device.
