Selective Blanking for Bank Document Image Viewing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In a check truncation environment, there is a need to selectively blank out sensitive areas of information on bank document images, such as checks and image replacement documents (IRDs), based on the security permission level of the viewer to ensure confidentiality.
Innovation Solution
A method and apparatus that determine the security permission level of the user and the type of bank document, and then selectively blank out identified sensitive areas on the image of the bank document during presentation, using a processor and user interface to display the image with sensitive information obscured.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the complete bank document image is displayed to all users, then information completeness is improved, but security and confidentiality are compromised
Solution Approach 1:
The system applies different display qualities to different regions of the same document image based on user permissions. Sensitive areas such as account numbers, routing numbers, and personal information are selectively blanked out or obscured for users without adequate clearance, while authorized users can view the complete unobscured document. This resolves the contradiction by maintaining information completeness for authorized users while protecting security for unauthorized users.
Solution Approach 2:
The document display system dynamically adjusts the level of obscuration based on the user's security permission level. The system evaluates the user's credentials and automatically modifies which portions of the document are visible or blanked out, rather than using a static display approach. This dynamic adaptation allows the system to provide complete information to authorized personnel while automatically protecting sensitive areas for unauthorized personnel.
2Reliability
If security permission levels are implemented to protect sensitive information, then confidentiality is improved, but system complexity increases
Solution Approach 1:
The system automatically determines user permission levels and selectively blanks out sensitive areas without requiring manual intervention or complex configuration for each user. The apparatus autonomously evaluates user credentials against the document type and automatically applies appropriate obscuration, reducing the operational complexity while maintaining strong confidentiality controls.
Solution Approach 2:
The security system is designed to handle multiple document types (checks, image replacement documents, electronic checks) and multiple user permission levels through a single unified apparatus. The same core mechanism of selective blanking applies across different document formats and permission scenarios, reducing overall system complexity compared to implementing separate security systems for each document type.

AI summary
A method is provided of a financial institution presenting an image of a bank document in a check truncation environment. The method comprises determining security permission level associated with a person to be presented with the image of the bank document, determining type of the bank document, locating a first sensitive area associated with the bank document, and presenting on a screen of a monitor the image of the bank document with the first sensitive area in the image being selectively blanked out based upon the security permission level associated with the person to be presented with the image of the bank document.
