Identification Document Data Verification via Template Image Comparison
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Manual collection of personal data from identification documents is error-prone and time-consuming, and direct data comparison is often not legally permitted due to data protection regulations, necessitating a verification method that complies with these regulations.
Innovation Solution
The method involves capturing an image of the identification document and comparing it with a test image generated from an electronically filled document template, allowing for optical image comparison without direct data processing, thus verifying data accuracy while adhering to data protection regulations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual data recording is used, then data protection regulations are complied with, but accuracy and efficiency deteriorate due to human error and time consumption
Solution Approach 1:
The patent introduces an intermediary verification process using document templates and image comparison. Instead of directly comparing extracted data with source data (which would violate data protection laws), the system creates a visual representation (test image) from the template filled with captured data, and compares this image with the original document image. This intermediary visual comparison mechanism enables verification while maintaining data protection compliance.
Solution Approach 2:
The patent creates a copy of the identification document in the form of a document template that can be electronically filled with captured data. This template copy serves as a verification medium, allowing the system to check data accuracy by comparing the filled template's visual representation against the original document image, thereby avoiding direct manipulation or storage of sensitive personal data.
2Productivity
If automated data extraction is used, then efficiency is improved, but data protection compliance deteriorates due to legal prohibitions on automated collection
Solution Approach 1:
The system uses image comparison as an intermediary verification step that does not involve direct electronic processing or storage of personal data for comparison purposes. The verification is performed visually through image matching, which falls outside the scope of automated data collection prohibitions while still providing efficiency benefits over purely manual verification.
Solution Approach 2:
The patent replaces the mechanical process of manual data entry and verification with an automated image-based verification system. By substituting manual comparison with automated optical image comparison, the system achieves efficiency improvement without violating data protection regulations that prohibit automated personal data processing.
3Measurement precision
If direct data comparison is performed, then verification accuracy is improved, but data protection compliance deteriorates due to direct data processing
Solution Approach 1:
Instead of directly comparing personal data values, the patent creates a visual copy (test image) from the document template filled with captured data and compares this image copy with the original document image. This copying approach maintains verification accuracy by preserving the visual appearance and layout while avoiding direct electronic handling of sensitive data for comparison.
Solution Approach 2:
The patent introduces an intermediary visual representation layer between the captured data and the comparison process. The test image serves as this intermediary, translating electronic data into a visual format that can be compared with the original document image without requiring direct electronic data processing or storage of personal information for verification purposes.

AI summary
The invention relates to a method for detecting data of an identification document, having the steps of detecting (201) the data of the identification document, electronically entering (203) the detected data of the identification document into an electronic document template which is assigned to the identification document in order to obtain a comparison template, generating (205) a test image from the comparison template, detecting (207) an optical image of the identification document by means of an image camera in order to obtain a document image, and electronically comparing (209) the document image with the test image in order to check the detection of the data.
