Data Access Lockdown Mechanism for Cloud Storage Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face issues with unauthorized access and data leakage when sharing information online, as existing systems lack a straightforward method to quickly suspend or lock down access to shared data.
Innovation Solution
A system and method that allow users to request and implement a 'lockdown' of their online accounts, modifying access settings to prevent other users from accessing shared data by replacing current sharing values with a lockdown value, thereby disabling access without further action from the user.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If users share information online through cloud storage and social networks, then information accessibility and collaboration are improved, but unauthorized access and data leakage risks increase
Solution Approach 1:
The system applies preliminary anti-action by enabling users to proactively lock down their data before unauthorized access occurs. The lockdown mechanism preemptively blocks access to shared files, preventing the harmful effect of unauthorized access while maintaining the beneficial sharing capability when unlocked.
Solution Approach 2:
The patent introduces an intermediary mechanism (the lockdown feature) between the user's sharing intent and the actual data access. This intermediary allows the system to maintain normal sharing operations while providing a control mechanism that can block access when necessary, thus resolving the contradiction between sharing capability and security.
2Reliability
If users manually manage access settings for each shared file, then data security is improved, but operation complexity and time consumption increase
Solution Approach 1:
The patent merges the security control function into a single unified lockdown mechanism that applies to all shared files simultaneously. Instead of requiring users to manually manage access settings for each file individually, the lockdown feature combines all access control actions into one operation, dramatically improving ease of use while maintaining security.
Solution Approach 2:
The lockdown mechanism serves multiple functions simultaneously: it blocks access to all shared files, preserves data integrity, and maintains security across different sharing platforms (cloud storage, social networks). This multi-functionality eliminates the need for separate manual access management for each file or platform.
3Loss of time
If users implement quick lockdown of all data, then response time to data breaches is improved, but system complexity increases
Solution Approach 1:
The patent extracts the essential security control function from the complex access management system and implements it as a simple lockdown mechanism. By separating the core locking function from the broader access control infrastructure, the system achieves rapid response capability without requiring complex implementation details to be visible or manageable to users.
Data Source
AI summary
Data access lockdown is described, including receiving a request from a first user to disable access to all data that are access-controlled by the first user based on at least one setting. The data are shared with at least one other user. In response to the request, modifying, without further action by the first user, the at least one setting by replacing a current value indicative of at least some of the data being shared, with a lockdown value indicative of disablement of access to all the data access-controlled by the first user, so as to prevent the at least one other user from accessing any of the data.
