UID Placement in Electronic Signature Documents
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic signature services face challenges in applying universal identifiers (UIDs) to documents without overlapping with content, leading to obscuration and reduced effectiveness in serving their purpose.
Innovation Solution
A method involving parsing image files to obtain content vectors, measuring overlap quantities, and selecting optimal UID locations to prevent overlap, assisted by user preferences and automatic placement to ensure the UID does not obscure document content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the UID is automatically applied to the document by the electronic signature service, then the efficiency and automation of the signature process is improved, but the UID may overlap with document content causing obscuration and reducing reliability
Solution Approach 1:
The system performs preliminary analysis of the document image to identify content regions and potential UID placement areas before applying the UID. By pre-processing the document to create a content map and calculate overlap risks, the system ensures the UID is placed in a location that avoids obscuring important content, thus maintaining both automation efficiency and document integrity
Solution Approach 2:
The system calculates an overlap risk score based on the detected document content and potential UID placement location. This feedback mechanism allows the system to evaluate whether a proposed UID placement would cause obscuration and adjust the placement accordingly, ensuring the UID does not compromise document legibility while maintaining automated processing
2Device complexity
If the UID placement location is determined without analyzing document content, then the device complexity is reduced, but the UID may overlap with important content such as signature blocks or barcodes
Solution Approach 1:
The system segments the document image into different regions by detecting content boundaries such as text lines, signature blocks, and barcodes. By dividing the document into content areas and safe placement areas, the system can identify suitable UID locations without requiring complex analysis of the entire document, thus reducing overall system complexity while avoiding content obscuration
Solution Approach 2:
The system introduces an intermediate content map or overlap risk assessment layer between the UID placement decision and the actual document. This intermediary structure allows the system to evaluate potential UID placements against document content without directly complex interactions, simplifying the overall system architecture while preventing harmful overlaps
Data Source
AI summary
A method for preventing overlap during the application of a universal identifier (UID) to a signature document in an electronic signature service is disclosed. The method includes parsing an image file of the signature document to obtain a content vector. A set of addresses of the content vector uniquely correspond with a set of locations in the image. Each value in the content vector indicates content at a corresponding location in the image. The method also includes measuring an overlap quantity for a potential UID location using the content vector to measure the overlap quantity. The method also includes selecting a UID location in the signature document using the overlap quantity. The method also includes applying the UID to the signature document using the UID location.
