Password-Based File Access Control System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current password-protected file sharing systems are cumbersome to manage, as file owners cannot track who accesses the files, and unintended users can gain access when passwords are shared or compromised, leading to difficulties in maintaining access control and security.
Innovation Solution
The system allows file owners to manage access by designating groups of users with unique identifiers, communicating passwords securely, and authenticating users through a combination of passwords and identifiers, thereby simplifying access management and enhancing security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If password protection is used for file sharing, then file security is improved, but ease of operation deteriorates due to password management complexity
Solution Approach 1:
The patent introduces an intermediary authentication system that mediates between the password protection mechanism and the users. This system uses unique identifiers (such as email addresses, phone numbers, or employee IDs) as intermediaries to manage access rights, eliminating the need for users to manually handle passwords while maintaining security through the intermediary's verification process.
2Ease of operation
If file owners share passwords with users, then access control is improved, but reliability deteriorates as file owners cannot track who accesses the file
Solution Approach 1:
The patent implements a feedback mechanism where the authentication system automatically tracks and reports access information to the file owner. When a user accesses a file using their unique identifier, the system records this access event and provides feedback to the file owner, enabling them to monitor who accesses their files without requiring manual password management or communication.
3Adaptability or versatility
If multiple dedicated spaces are created for users with varying security clearances, then adaptability is improved, but device complexity increases
Solution Approach 1:
The patent creates a universal authentication system that handles multiple security clearance levels through a single interface. Instead of requiring separate dedicated spaces for different user groups, the system uses a universal identifier-based authentication mechanism that automatically applies appropriate access rights based on the user's security clearance, making the system adaptable to various security requirements without increasing structural complexity.

AI summary
Methods and systems are provided for managing access to a file. The methods and systems may include locking access to the file using a password accessible security setting. The methods and systems may include designating a password as an unlock password. The methods and systems may include communicating the password to a first group of users. The methods and systems may include providing a prompt to input the unlock password upon a request to access the file. The methods and systems may include providing access to the file in response to inputting the unlock password. The methods and systems may include authenticating each unauthenticated user that inputs the unlock password. The methods and systems may include deactivating the password as the unlock password. The methods and systems may include removing authentication from a user in response to the user meeting a predetermined condition.
