Document Processing Apparatus with Face Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image processing systems face inconvenience in uniformly prohibiting or allowing processing of documents containing personal information, as they often require user-specific registration and lack efficient methods to authenticate the document owner.
Innovation Solution
An image processing apparatus equipped with a camera and an image reading unit that captures and compares the face of a person with the face image extracted from a document, allowing processing only if the images match, thereby ensuring authorized access to personal information documents.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If personal information processing is uniformly prohibited, then privacy security is improved, but processing convenience deteriorates
Solution Approach 1:
The patent applies local quality by differentiating access rights to personal information based on individual user authentication. Instead of uniform prohibition or permission, the system grants specific processing permissions to specific authenticated users, allowing privacy protection while enabling necessary processing for authorized individuals.
Solution Approach 2:
The patent implements preliminary action by performing face authentication before allowing document processing. The system captures and verifies the user's face image against registered data in advance, ensuring authorization is established before any personal information processing occurs, thus preventing unauthorized access.
2Reliability
If server-based permission registration is implemented, then access control reliability is improved, but system complexity deteriorates
Solution Approach 1:
The patent applies self-service by enabling the image processing apparatus to perform its own authentication and authorization decisions locally. The apparatus contains face recognition and permission verification capabilities, allowing it to independently determine whether to permit processing without requiring external server registration or intervention, thus reducing system complexity while maintaining security.
3Measurement precision
If face authentication is added, then authorization accuracy is improved, but operation time deteriorates
Solution Approach 1:
The patent applies partial action by implementing face authentication only when processing documents containing personal information, rather than for all document processing operations. The system selectively applies the authentication mechanism based on document type detection, reducing unnecessary authentication time while maintaining security where required.

AI summary
An image processing apparatus includes a camera, an image reading unit, and a controller. The camera is configured to capture an image of a face of a person. The image reading unit is configured to read a document and to output a document image. The controller is configured to perform control to permit certain processing on the document image if the image of the face captured by the camera matches a face image extracted from the document image.
