Automated Email Document Redaction by Recipient Clearance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Manual classification of sensitive information in email messages is labor-intensive, prone to errors, and inefficient in ensuring only authorized recipients access restricted content.
Innovation Solution
A computerized method and system for classifying and redacting segments of documents, including email messages, using a set of classification options, marking segments accordingly, and generating versions based on recipient clearance levels, with optional AI analysis and real-time redaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual classification marks are inserted into email message segments, then classification accuracy is improved, but labor intensity and time consumption increase significantly
Solution Approach 1:
The system performs preliminary classification by automatically analyzing email content and pre-inserting classification marks into segments before the sending process. This preliminary action eliminates the need for manual mark insertion at the time of sending, thereby maintaining high classification accuracy while significantly reducing time consumption and labor intensity.
2Measurement precision
If manual classification marks are inserted into email message segments, then classification accuracy is improved, but the process becomes more complex and error-prone
Solution Approach 1:
The system implements self-service classification by automatically analyzing email content, identifying sensitive segments, and inserting appropriate classification marks without human intervention. This automated self-service process eliminates manual errors associated with manual mark insertion while maintaining high classification accuracy, thereby improving reliability.
3Reliability
If real-time redaction is performed based on recipient clearance levels, then security is improved, but processing speed may be reduced
Solution Approach 1:
The system performs preliminary redaction processing by pre-identifying classified segments and preparing redaction rules before the email is sent. When the email reaches the recipient, the pre-prepared redaction is applied automatically based on the recipient's clearance level. This preliminary preparation maintains high security while minimizing real-time processing overhead and preserving processing speed.

AI summary
A method for classifying and redacting electronic documents, for example an email message, is described. The classification and redaction of segments of the email message are based on rules. Using the rules, multiple versions of the email message, each corresponding to recipients with specific clearance levels are generated. A selective redacting of certain segments of the email message concurrently with sending previously redacted segments of the same email message is described. A corresponding system for classifying and redacting electronic documents is also provided.
