Card Catalog File Sharing with Auto-Lock Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for sharing large volumes of files across multiple devices and users face challenges such as limited scalability, security concerns, difficulty in managing file versions, and loss of context due to metadata and application settings, with existing solutions like email, file servers, and web storage being inefficient and insecure.
Innovation Solution
A system that uses a card catalog to represent files and associated metadata, allowing for hierarchical organization, seamless access across devices, and robust security through name/password and ACLs, enabling transparent sharing and management of large collections of files while maintaining context.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If files are shared via email, then accessibility and ease of use are improved, but security and file size limitations worsen
Solution Approach 1:
The patent introduces a file sharing server as an intermediary between users, replacing direct email file transfers. The server handles file storage, security management, and distribution, allowing users to access files through controlled links while maintaining security policies. This resolves the contradiction by providing email-like accessibility through web interfaces while enforcing security controls at the server level.
2Reliability
If files are stored on a file server, then scalability and security are improved, but ease of access and connectivity issues worsen
Solution Approach 1:
The patent makes the file sharing server accessible through multiple interfaces including web browsers and mobile devices, not just traditional file server protocols. Users can access files via email-like links, direct web URLs, or mobile applications, making the system universally accessible across different platforms and devices while maintaining centralized security control.
Solution Approach 2:
The server acts as an intermediary that provides unified access points for multiple users and devices. Instead of requiring direct network connectivity to the file server, users receive mediated access through email links or web interfaces, simplifying connectivity while maintaining security.
3Ease of operation
If files are copied to portable storage devices, then portability and accessibility are improved, but performance speed and version management worsen
Solution Approach 1:
Instead of physically copying files to portable storage devices, the patent creates digital copies in the form of access links and references that can be instantly distributed via email or messaging. These digital copies provide the same portability benefit without the physical transfer bottleneck, allowing instant file access from any location with network connectivity.
4Reliability
If file sharing systems are made more secure, then security and reliability are improved, but ease of use and user management worsen
Solution Approach 1:
The patent implements self-service features where users can independently manage their own file sharing preferences, generate access links, and control their shared files without requiring administrative intervention. The system automatically handles user authentication, access control list (ACL) management, and security policy enforcement, reducing the complexity burden on both users and administrators while maintaining strong security.
Data Source
AI summary
Methods and systems for providing easy access to information and sharing are provided. Embodiments of the present invention enable a host to grant access to published content to one or more users in a manner in which the user(s) can scan small portions of information to decide which information is desired. The embodiments described herein enable, for example, a user to see a library of content that is larger than the storage capacity of the computing unit used by the user. The sharing of information is also secured through the use of auto-lock keys and the creation of abstract identities for the host and each user.
