Automated Security Policy Assignment for Digitized Documents
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for securing paper-based documents are inefficient and prone to improper access, as they rely on manual review and penalties, which are time-consuming and insufficient in regulating access to digitized documents.
Innovation Solution
A system that automates the assignment of protection to digitized documents using a client-server network, where a central server with a security policy assigner and evaluator analyzes document content, applies security policies based on user identity, role, and context, and enforces access restrictions dynamically.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual review is used to determine security policy for documents, then security can be assigned to documents, but the process becomes very expensive and time-consuming
Solution Approach 1:
The patent replaces the manual mechanical review process with an automated optical character recognition (OCR) system and computer algorithm that extracts text from documents and automatically assigns security policies based on keywords and content analysis, eliminating the need for human reviewers while maintaining security standards
Solution Approach 2:
The system enables documents to self-categorize and self-assign security policies through automated text extraction and keyword matching algorithms, allowing the document processing system to determine appropriate security levels without external human intervention
2Ease of operation
If digital format is used for documents, then documents can be more easily searched, moved, and shared, but documents become subject to more improper access including viewing, distribution, and copying
Solution Approach 1:
The patent applies different security policy levels to different documents or portions of documents based on their content analysis, allowing highly sensitive documents to have restricted access while less sensitive documents remain more accessible, creating granular security control that adapts to each document's specific needs
Solution Approach 2:
The system introduces an automated security policy assignment system that acts as an intermediary between the digital document and the user, automatically evaluating document content and applying appropriate security restrictions without requiring manual human judgment for each access request
3Reliability
If penalties are used to regulate person's behavior regarding document access, then some deterrence is provided, but a person willing to risk punishment may still access the document
Solution Approach 1:
The patent implements security restrictions and access controls before any document access can occur, automatically assigning security policies and enforcing restrictions in advance rather than relying on post-access penalties, preventing improper access before it can happen

AI summary
Content analysis is performed on documents that have been scanned or converted into a digital format. Based on the content analysis of a document, a security policy is selected and assigned or attached to the document. The security policy prevents the document from being improperly accessed. In a specific implementation, the documents include patient medical records.
