Privacy Enhanced Push Notification System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing notification systems fail to effectively manage sensitive information on mobile devices, often revealing personal data in undesirable situations, either by hiding all notifications from sensitive applications or using context rules without considering user-specific conditions.
Innovation Solution
A privacy-enhanced notification system that uses a client device to determine if a notification contains sensitive data and sets a sensitivity flag, allowing for controlled display based on user-defined preferences, such as hiding notifications in specific situations or until a later time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If all notifications from sensitive applications are hidden, then user privacy is improved, but notification delivery reliability deteriorates
Solution Approach 1:
The patent applies local quality by differentiating the handling of notifications based on their individual sensitivity characteristics. Instead of uniformly hiding all notifications from sensitive applications, the system analyzes each notification's content to determine its sensitivity level and applies appropriate handling rules selectively. This allows sensitive notifications to be hidden while maintaining delivery of non-sensitive notifications from the same application.
Solution Approach 2:
The patent segments notifications into distinct categories based on their sensitivity content. By dividing notifications into sensitive and non-sensitive segments, the system can apply different delivery policies to each segment independently. This segmentation enables the system to hide only the sensitive portion while preserving the delivery of non-sensitive notifications, thus resolving the contradiction between privacy protection and notification reliability.
2Device complexity
If context rules are used without user-specific conditions, then system complexity is reduced, but user privacy control deteriorates
Solution Approach 1:
The patent implements self-service by enabling users to define their own privacy preferences and conditions without requiring complex system configuration. Users can specify which notifications they want to hide and under what conditions, and the system automatically applies these user-defined rules. This approach maintains simplicity while providing personalized privacy control, as the complexity is shifted from the system to the user's preference configuration.
Data Source
AI summary
A method of privacy enhanced notification includes receiving, by a client device, a notification associated with an application. The method includes identifying a negative situation associated with the client device in response to receiving the notification. The method further includes determining whether the notification includes sensitive data. The method also includes setting a sensitivity flag as true in response to the negative situation and a determination that the notification includes sensitive data. The method includes setting the sensitivity flag as false in response to a determination that the notification does not include sensitive data. The method includes presenting the notification on an electronic display of the client device according to the sensitivity flag.
