Log Creation Unit Concealing User Data in Electronic Document Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information processing systems lack effective mechanisms to protect user privacy during electronic document transmission by concealing sensitive information in transmission logs, which can lead to unauthorized access and exposure of personal data.
Innovation Solution
An information processing apparatus equipped with a transmission setting unit, a transmitting unit, and a log creation unit that conceals user information by encrypting or deleting sensitive data from transmission logs, ensuring only authorized users can access the information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If transmission logs record complete user information for tracking and auditing purposes, then log completeness and traceability are improved, but user privacy and security are compromised due to unauthorized access risks
Solution Approach 1:
The patent extracts and removes sensitive personal information from transmission logs before recording. The log creation unit selectively excludes user identifiers, contact information, and other sensitive data from being written to the log, thereby maintaining log functionality while preventing unauthorized access to personal information.
Solution Approach 2:
The patent applies different quality characteristics to different parts of the log data. Non-sensitive transmission metadata (timestamps, document types, transmission status) is recorded in full detail, while sensitive user information is either concealed or recorded in an encrypted format accessible only to authorized personnel with appropriate clearance levels.
2Reliability
If transmission logs store detailed user data for audit purposes, then audit capability is improved, but system security and user privacy are worsened due to potential data breaches
Solution Approach 1:
The patent introduces an intermediary processing layer between the transmission system and the log storage. The log creation unit acts as a mediator that receives transmission data, filters out or encrypts sensitive information, and then writes only the processed data to the log. This intermediary mechanism maintains audit capability while protecting user information confidentiality.
Solution Approach 2:
The patent transforms sensitive information parameters before logging. User identifiers are replaced with anonymized codes, contact information is masked or removed, and personal data is encrypted. These parameter changes allow the log to maintain traceability and audit capability without storing actual sensitive user information in plaintext.
