Image Processing for Personal Information Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Financial institutions and mobile communication companies face the challenge of protecting personal information, such as resident registration numbers and fingerprint data, from exposure during the scanning and storage of identification cards, which can lead to secondary damage due to hacking.
Innovation Solution
An image forming apparatus and method that scans identification documents, detects personal information areas, and either blurs or encodes them to prevent exposure, using a processor to recognize document types, detect personal information areas, and convert them into blank images or mosaics, while also transmitting information to an external server for encoding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If personal information is stored in scanned images for identification verification, then identification confirmation is achieved, but personal information exposure risk increases due to potential hacking
Solution Approach 1:
The patent extracts personal information from the scanned image by detecting specific areas containing sensitive data (resident registration numbers, fingerprint information, etc.) and separates this information for special processing. The processor identifies personal information regions and applies encoding or blurring treatments specifically to these extracted areas, while preserving the rest of the document for identification verification purposes.
Solution Approach 2:
The patent applies preliminary protective actions by encoding or blurring personal information areas before the scanned image is stored or transmitted. This preventive measure ensures that even if the scanned image is accessed or hacked, the personal information remains protected and unusable. The encoding process converts readable personal information into unreadable formats in advance.
2Object-affected harmful factors
If personal information is encoded or blurred in scanned images, then personal information protection is improved, but information usability for verification purposes deteriorates
Solution Approach 1:
The patent applies different quality treatments to different regions of the scanned image. Personal information areas are encoded or blurred to protect privacy, while non-personal information areas remain clear and readable for verification purposes. This local differentiation ensures that protection is applied only where necessary without compromising the usability of essential document information.
Solution Approach 2:
The patent segments the scanned image into distinct regions: personal information areas and non-personal information areas. By dividing the image content and applying different processing treatments to each segment, the system maintains verification capability for document content while protecting sensitive personal data through selective encoding or blurring of specific segments.

AI summary
An image forming apparatus and a method for imaging process thereof are provided. The image forming apparatus includes a scanner configured to scan a transcript and generate a scanned image, at least one processor configured to determine a type of the transcript using the scanned image, detect a personal information area within the scanned image based on the determined type of the transcript, and correct the scanned image by blurring the detected personal information area, and an image forming device configured to print the corrected scanned image.
