Unified Media Account Access Control Across Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face challenges in managing access to both local and network media sources, as existing systems lack a straightforward method to control and synchronize access permissions across devices, leading to inconsistencies and potential data security issues.
Innovation Solution
A computing system that allows users to grant and revoke access to media accounts through a single input, using access tokens to manage permissions on both local media libraries and network media services, ensuring consistent access control across devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users manage access to local and network media sources separately, then each media source can be controlled independently, but access consistency and user convenience deteriorate
Solution Approach 1:
The patent combines access control for local media libraries and network media services into a single unified system. Users grant or revoke access to both media sources through one interface, and the system automatically propagates these permission changes across all devices, eliminating the need to manage access separately for each media source.
Solution Approach 2:
The access control system serves multiple functions simultaneously: it manages permissions for both local and network media sources, synchronizes access across multiple devices, and provides a single user interface for all access control operations. This multi-functional approach simplifies the overall system while maintaining comprehensive control.
2Reliability
If access tokens are managed locally on each device, then device-specific access control is simple, but access consistency across devices deteriorates
Solution Approach 1:
The system implements continuous feedback loops where access token changes on one device automatically trigger updates on other devices. When a user grants or revokes access on one device, the system detects this change and propagates the updated access token to all other devices, ensuring consistent access permissions across the entire device ecosystem.
Solution Approach 2:
The patent introduces a centralized access token management service that acts as an intermediary between devices. This service coordinates access token issuance, revocation, and synchronization across all devices, eliminating the need for each device to independently manage its own access tokens and ensuring consistent access control throughout the system.
3Adaptability or versatility
If applications have broad access to media accounts, then application functionality is enhanced, but data security and user control deteriorate
Solution Approach 1:
The patent segments access permissions at multiple levels: users can grant access to specific applications, to specific media sources (local or network), and to specific devices. This granular segmentation allows applications to access media data only when and where explicitly permitted, maintaining security while enabling functionality. Applications receive access tokens that are valid only for authorized contexts, preventing unauthorized access.
Data Source
AI summary
In some implementations, a computing system can manage access to media sources associated with a user's media account. For example, the system can coordinate access to a user's media account between local and network devices such that when access to the user's media account is granted to an application on a user device, the application can access both local and network media sources associated with the user's media account. Similarly, when access to the user's media account is revoked from an application at a user device or at a network device, the application is prevented from accessing both local and network media sources associated with the user's media account.
