OCR-Based Password Generation for Scanned Document Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing scanners and multifunction peripherals lack an effective method to securely generate and apply passwords for protecting scanned documents containing personal information, such as ID cards, which are vulnerable to leakage.
Innovation Solution
An information processing apparatus that selects items from a formatted document using OCR results to generate a password, converts document data into password-protected format, and sets attribute information for the protected data, utilizing a selection unit, generation unit, conversion unit, and setting unit to create a secure password-based protection mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a password is set for the scanned document file as a measure against leakage, then security is improved, but the complexity of the password management process increases
Solution Approach 1:
The system automatically generates passwords using OCR-recognized information from the scanned documents themselves (such as ID card numbers, names, or other unique identifiers). This self-service approach eliminates the need for manual password creation and management, resolving the contradiction by improving security through automated password protection while avoiding increased operational complexity
Solution Approach 2:
The system transforms document content parameters (text recognized by OCR) into security parameters (passwords). By changing the parameter type from document information to authentication credentials, the system automatically establishes password protection without requiring complex manual intervention, thus improving security while maintaining process simplicity
2Reliability
If manual password creation is used for protecting scanned documents, then security can be established, but time consumption and operational complexity increase
Solution Approach 1:
The system performs preliminary actions by automatically extracting and utilizing information already present in the scanned documents during the scanning process itself. The OCR recognition and password generation occur simultaneously with document scanning, eliminating subsequent manual password creation steps and reducing time loss while maintaining security
Solution Approach 2:
The system merges the document scanning, OCR recognition, and password generation processes into a single integrated workflow. By combining these previously separate operations, the system establishes security measures without adding time consumption, as the password creation is embedded within the existing document processing pipeline

AI summary
An information processing apparatus includes a selection unit configured to select an item to be used for a password from among items written on a formatted document, a generation unit configured to generate a password based on a character string obtained as a character recognition result for the item selected by the selection unit on the formatted document, a conversion unit configured to convert document data obtained by reading the formatted document into document data protected with the password, and a setting unit configured to set information for identifying the item used for generation of the password as attribute information of the protected document data.
