Dual Identifier Push Content Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for managing push content on computing devices fail to effectively handle changes in device identifiers, leading to synchronization issues and unauthorized content delivery when devices are transferred or changed.
Innovation Solution
A method and system that determine changes in relative device identifiers, unsubscribe from existing content subscriptions, and optionally re-subscribe to content services upon user input, using a processor to manage content subscription information and communicate with network components to ensure authorized content delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the system uses relative device identifiers for content subscription management, then the subscription process is simple and device-specific, but synchronization issues and unauthorized content delivery occur when devices are changed
Solution Approach 1:
The patent segments device identification into two distinct parts: relative device identifiers (device-specific, changeable) and absolute device identifiers (network-wide, unique). This segmentation allows the system to maintain simple device-specific subscriptions using relative identifiers while ensuring reliable authorization through absolute identifiers that persist across device changes.
Solution Approach 2:
The patent introduces an intermediary mechanism (the dual-identifier system with network component coordination) that bridges the gap between simple device-specific subscription management and reliable authorization. When device identifiers change, the intermediary process coordinates between the device, network components, and content servers to maintain proper authorization without disrupting the subscription model.
2Speed
If the system maintains content subscription information locally on the device, then access speed and autonomy are improved, but synchronization issues arise when devices are transferred
Solution Approach 1:
The patent implements preliminary action by establishing a dual-identifier subscription model before device changes occur. The absolute device identifier is pre-configured and registered with network components, so when a device is transferred or identifiers change, the system can immediately verify authorization without disruption to locally cached content or subscription information.
3Adaptability or versatility
If the system allows device identifier changes, then device flexibility and user control are improved, but unauthorized content delivery and synchronization issues occur
Solution Approach 1:
The patent applies dynamics by making the identifier system adaptable: relative device identifiers can change freely to support device flexibility and user control, while absolute device identifiers remain stable and unique for reliable authorization. The system dynamically adjusts between these two identifier types based on the operational context, allowing device changes while maintaining security.
Data Source
AI summary
A method, system and apparatus for management of push content when changing computing devices is provided. In an example embodiment, a computing device is configured to maintain an absolute identifier of the device that remains unchangeable, and a relative identifier that can be changed. The processor of the device is configured to ascertain if the relative identifier has been changed, and accordingly notify any network infrastructure that is configure to send push content to the device to cease delivery of such push content.
