Notification Bar Interception Program for Android Malicious Ad Blocking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of smart terminals are frequently annoyed by malicious notification bar advertisements that are difficult to identify and intercept due to the lack of sender identification in the Android system's notification bar message interface, leading to unwanted ad exposure and potential software downloads.
Innovation Solution
A method and system that injects an interception program into the notification bar message process, allowing it to intercept and prompt users about malicious advertisements by obtaining advanced privileges in the mobile terminal system, thereby identifying and blocking such messages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the Android system's notification bar message interface is used without sender identification, then the system maintains openness and compatibility, but users cannot identify the sender of notification bar advertisements, leading to malicious ad exposure
Solution Approach 1:
The patent introduces an intermediary component (notification bar manager or interception program) that mediates between the notification bar message interface and the user. This intermediary captures notification bar messages, identifies their senders, and presents this information to users, thereby resolving the information loss without modifying the core Android system interface and maintaining its openness
Solution Approach 2:
The patent segments the notification bar message handling into separate functional components: message capture, sender identification, and user presentation. This segmentation allows the system to maintain overall openness while adding specific functionality for sender identification through modular components that operate independently within the existing system architecture
2Productivity
If third-party advertisement SDKs are used to generate revenue, then developers can make profit, but malicious advertisements cannot be cleared or closed, consuming user resources and money
Solution Approach 1:
The patent implements a feedback mechanism where the notification bar manager monitors and analyzes notification bar messages in real-time, identifies malicious patterns, and provides feedback to users through sender identification and interception capabilities. This feedback loop enables users to recognize and block malicious advertisements while preserving legitimate ad revenue streams
Solution Approach 2:
The patent applies preliminary anti-action by proactively identifying and intercepting malicious advertisements before they can fully execute their harmful purposes. The interception program detects suspicious patterns in advance and prevents these malicious ads from being displayed or downloaded, countering the harmful effects before they manifest
3Reliability
If an interception program is injected into the notification bar message process, then malicious advertisements can be identified and blocked, but the device complexity increases
Solution Approach 1:
The patent designs the notification bar manager and interception program with multi-functionality, allowing them to perform multiple tasks: capturing notification bar messages, identifying senders, filtering malicious content, and presenting information to users. This universality reduces the need for separate specialized components, thereby limiting the increase in device complexity while maintaining reliable interception capabilities
