Portion-Level Content Encoding for Granular Document Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing content management systems lack the ability to provide granular, portion-level security while maintaining document integrity and user access based on varying user authorization levels, leading to inefficiencies and document management challenges.
Innovation Solution
A system and method for security-level based content encoding that allows different portions of content to be encoded with specific authorization levels, enabling selective access and dynamic reclassification, with features like hierarchical codebooks, time-based access, and user-specific watermarking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If uniform security controls are applied to entire documents, then security level is improved, but ease of operation deteriorates
Solution Approach 1:
The patent segments a document into multiple portions, each with its own security level. The system divides the document content into distinct sections that can be independently classified and protected at different security levels, allowing users to access only the portions they are authorized to view while maintaining overall document integrity.
Solution Approach 2:
The patent applies different security levels to different portions of the same document based on the sensitivity of the content in each portion. This allows the system to tailor security controls locally to each section rather than applying a uniform security level to the entire document, improving both security precision and user accessibility.
2Reliability
If multiple versions of content are created for different security levels, then security level is improved, but device complexity deteriorates
Solution Approach 1:
The patent merges multiple security-level protected content portions into a single unified document structure. Instead of maintaining separate document versions for different security levels, the system consolidates all content into one document with embedded security metadata, reducing the number of documents to manage while maintaining granular security controls.
Solution Approach 2:
The patent creates a universal document structure that can serve multiple security levels simultaneously. A single document can be accessed by users with different authorization levels, with the system automatically filtering and displaying only the portions each user is authorized to view, eliminating the need for multiple separate document versions.
3Ease of operation
If document-level access control is used, then ease of operation is improved, but manufacturing precision deteriorates
Solution Approach 1:
The patent segments access control from the document level to the portion level by dividing the document into multiple portions with distinct security classifications. This allows the system to apply access control rules to specific sections rather than the entire document, enabling precise control over which users can access which content while maintaining ease of document management.
Data Source
AI summary
A system and method for securing content using security-level based encoding. The system encodes different portions of content using encoding schemes associated with specific authorization levels. Users can only access portions of the content for which they have appropriate authorization, with unauthorized portions appearing restricted. The system provides granular, portion-level security while maintaining content integrity. Additional features include security level modification, hierarchical authorization structures, time-based access control, multi-factor verification, and unique identifier tracking for content access sessions.
