Surrogate Document Indicator in TIFF Headers for Check 21 Compliance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Financial institutions face challenges in identifying and managing surrogate document images within their systems, which cannot meet the requirements of legislation like Check 21, leading to the need for manual exception handling and audit listings.
Innovation Solution
Implementing a surrogate document image indicator in the TIFF header of image files, which includes placeholder information such as a graphical logo or text, to programmatically distinguish and handle surrogate images, reducing the need for exception and audit lists by using image quality inspection to replace low-quality scanned images with surrogate ones.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If surrogate document images are used to replace low-quality scanned images, then image quality and system reliability are improved, but device complexity and operational difficulty increase due to the need for manual tracking and audit listings
Solution Approach 1:
The patent segments the image data structure by adding a separate indicator field within the TIFF header that specifically marks surrogate images. This segmentation allows the system to distinguish surrogate images without complicating the overall image storage and retrieval architecture, as the indicator is a discrete element that can be independently processed.
Solution Approach 2:
The surrogate indicator acts as an intermediary element between the image data and the application logic. Instead of requiring complex manual tracking systems, the indicator serves as an automated signal that applications can read to determine whether an image is surrogate, thereby simplifying the operational process while maintaining reliability.
2Reliability
If manual exception handling and audit listings are used to track surrogate images, then compliance with Check 21 legislation is maintained, but productivity and processing speed decrease
Solution Approach 1:
The system performs self-service compliance tracking through the surrogate indicator mechanism. Applications automatically read the indicator to determine compliance requirements, eliminating the need for manual exception handling and audit listings. This self-service approach maintains Check 21 compliance while significantly improving processing speed by automating what was previously a manual process.
Solution Approach 2:
The patent replaces the mechanical system of manual tracking and audit listings with an automated electronic indicator system. The surrogate indicator in the TIFF header allows computer systems to automatically identify and handle surrogate images according to Check 21 requirements, substituting manual operational processes with automated electronic detection and decision-making.
3Quantity of substance
If surrogate images are stored without explicit indicators, then storage space is optimized, but information loss occurs regarding the surrogate status of images
Solution Approach 1:
The patent applies local quality by adding a specific indicator only where needed in the TIFF header structure. This localized addition provides the necessary information about image status without requiring changes to the entire image data structure or significant additional storage space. The indicator is embedded in the existing header format, maintaining storage efficiency while preventing information loss.
Data Source
AI summary
Surrogate document indicator and methods of using same. A surrogate document image encoded on a storage medium as part of a database or repository of images includes a surrogate document image indicator. In example embodiments, images within the system, including surrogate document images are stored in tagged image file format (TIFF) and the TIFF header includes the surrogate document image indicator. When images are retrieved by an application from an archive or a check image management system, each one is programmatically examined to detect the presence of the surrogate document image indicator. If necessary, the image with the indicator is treated as an exception.
