Granular Document Portion Classification via Painting Interaction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional techniques for classifying the sensitivity of electronic documents do not allow for different portions of a document to be classified at varying levels of sensitivity, leading to inadequate control over access and storage.
Innovation Solution
A software and hardware facility that enables users to interact with electronic documents by painting sensitivity classification levels onto specific portions using a palette, allowing for granular classification of document elements such as text, images, and other content types, and stores these classifications to manage access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a single sensitivity classification is applied to the entire document, then the classification process is simple and fast, but the access control granularity is insufficient
Solution Approach 1:
The patent segments the document into multiple portions and applies different sensitivity classifications to each portion independently. This allows fine-grained access control where different users can access different portions based on their authorization levels, while maintaining a simple classification interface for the user.
Solution Approach 2:
The patent enables different portions of the same document to have different sensitivity classifications (local quality) rather than applying a uniform classification to the entire document. This allows specific sensitive sections to be protected at higher levels while keeping non-sensitive portions accessible.
2Reliability
If different storage devices are used for documents with different sensitivity levels, then access control is enforced, but storage resources are inefficiently utilized
Solution Approach 1:
The patent merges multiple documents with different sensitivity classifications into a single storage location. The system enforces access control at the document portion level based on user authorization, eliminating the need for separate storage devices for different sensitivity levels while maintaining security.
3Reliability
If the entire document is stored on a restricted storage device to protect sensitive portions, then security is maintained, but access to non-sensitive portions is unnecessarily restricted
Solution Approach 1:
The patent segments the document into protected and non-protected portions, allowing users to access non-sensitive portions without requiring authorization for the entire document. This maintains security for sensitive sections while improving accessibility for non-sensitive content.
Solution Approach 2:
The patent applies different access restrictions to different portions of the document based on their sensitivity classification. Non-sensitive portions are accessible to all authorized users, while sensitive portions require specific authorization, optimizing both security and accessibility.
Data Source
AI summary
A facility for interacting with an electronic document is described. The facility causes to be displayed a visual representation of the document, and receives input representing a painting interaction with a portion of the displayed visual representation of the document that corresponds to a portion of the document. In response to receiving the first input, the facility imposes on the corresponding portion of the document a distinguished content classification level.
