Media Section Authentication for Granular Access Redaction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing access control systems fail to provide fine-grained access to sensitive information, allowing unauthorized access or denying access to authorized users due to insufficient granularity in access controls.
Innovation Solution
Implementing a multi-level authentication system that associates media with various authentication levels, encrypting or tokenizing media sections based on these levels, and dynamically adjusting access and redaction based on user authentication levels using encryption and tokenization processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If access control systems use coarse-grained authentication levels, then system complexity is reduced, but access precision and security control deteriorate
Solution Approach 1:
The patent divides the media into multiple sections, each associated with different authentication levels. This segmentation allows fine-grained access control where each section can be accessed at different authentication thresholds, achieving precise access control without requiring the entire system to be overly complex.
Solution Approach 2:
Different sections of the media are assigned different authentication levels based on their sensitivity. This local quality approach allows each section to have customized access control policies, enabling precise control over sensitive information while keeping less sensitive sections more accessible.
2Measurement precision
If authentication levels are made more granular, then access control precision improves, but ease of operation deteriorates
Solution Approach 1:
The system dynamically adjusts the authentication level required based on the section being accessed. Users don't need to manually select authentication levels; the system automatically applies the appropriate level based on the media section's sensitivity and the user's current authentication state, maintaining ease of operation while achieving precise control.
Solution Approach 2:
The system automatically manages authentication levels without requiring user intervention. The authentication mechanism self-adjusts based on the accessed section's requirements and the user's current state, eliminating the burden on users to manually manage complex authentication policies.
3Reliability
If all media sections are encrypted with high authentication levels, then security improves, but accessibility for authorized users deteriorates
Solution Approach 1:
The media is segmented into sections with different authentication levels. High-security sections are encrypted with higher authentication requirements, while lower-sensitivity sections use weaker authentication. This allows authorized users to access appropriate sections without being blocked by overly strict security measures on the entire media.
Solution Approach 2:
Different authentication levels are applied locally to different media sections based on their sensitivity. This ensures that high-security areas maintain strong protection while less sensitive areas remain accessible to authorized users with lower authentication requirements, balancing security and accessibility.

AI summary
A media is created. The media may be a document, an image, a video file, an audio file, a real-time communication session, an email, a chat session, and/or the like. The media is associated with a plurality of authentication levels. For example, the media may use a first authentication level that requires a username/password and a second authentication level that requires a fingerprint scan of a user. The media is created based on a security process according to the plurality of authentication levels. For example, the security process may be an encryption process and/or a tokenization process. The media is divided into a plurality of sections based on the plurality of authentication levels. The security process is applied to the plurality of sections based on the plurality of authentication levels.
