Collaborative Playlist Access Tokens for Scheduled Permission Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional service providers lack adequate organization and sharing of related media content among users, and existing collaborative playlist systems provide insufficient security and control over access, allowing unauthorized access and manual management of access lists.
Innovation Solution
Implementing access policies and access tokens to manage access to collaborative playlists, enabling secure and automated control over which user accounts can access, what permissions they have, and scheduling future permission changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional service providers allow uploading or streaming of media content, then media content can be accessed by users, but adequate organization or sharing of related media content amongst users is not provided
Solution Approach 1:
The patent segments media content into playlists that can be independently created, shared, and managed. Each playlist is a discrete unit that organizes related media content, allowing users to share specific collections rather than managing all content individually. This segmentation enables versatile sharing while keeping the organization system manageable through modular playlist units.
Solution Approach 2:
The patent creates a universal playlist structure that serves multiple functions: organizing media content, enabling sharing among users, controlling access permissions, and facilitating collaborative management. This multi-functional playlist system addresses the need for versatile content sharing without requiring separate systems for each function, thereby reducing overall complexity.
2Adaptability or versatility
If existing collaborative playlist systems allow multiple users to access, then collaboration is enabled, but security and control over access is insufficient, allowing unauthorized access
Solution Approach 1:
The patent implements local quality by assigning different permission levels to different users for the same playlist. The owner has full control rights including the ability to remove users, while invited users have limited rights such as adding or removing items. This differentiated local quality approach enables collaborative access while maintaining security through role-based permission control.
Solution Approach 2:
The patent introduces an intermediary access control mechanism that mediates between the playlist owner and invited users. The system acts as a mediator by enforcing permission rules, validating user identities, and controlling what actions each user can perform. This intermediary layer enables collaboration while preventing unauthorized access through automated security checks.
3Ease of operation
If manual management of access lists is used, then user access can be controlled, but automated control and scheduling of future permission changes is not available
Solution Approach 1:
The patent enables preliminary action by allowing users to pre-configure permission changes and scheduling rules in advance. Users can set up automated permission modifications that will execute at future dates or under specific conditions, eliminating the need for manual intervention. This preliminary configuration maintains ease of operation through simple setup while achieving high automation in execution.
Solution Approach 2:
The patent implements self-service by enabling the system to automatically manage access permissions without requiring manual intervention. The automated scheduling system monitors conditions, executes permission changes autonomously, and manages access control lists without user involvement. This self-service capability maintains operational simplicity while achieving comprehensive automation.
Data Source
AI summary
The disclosed technology provides greater security and control to the field of collaborative playlists by utilizing access policies and access tokens to control which user accounts can access a collaborative playlist, what permissions are provided to user accounts that can access a collaborative playlist, and to schedule future permission changes.
