Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for verifying the authenticity of identity documents at Point of Sale (POS) systems are inefficient, leading to potential errors and queue buildup, as they often rely on manual processes or require expensive and complex systems.
Innovation Solution
A scanner equipped with white, UV, and IR light sources, along with a camera, detects and acquires images of the identity document, encrypts them, and sends them to an analysis server for verification, providing a quick and reliable method to authenticate the document and share extracted textual information with the POS system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual verification processes are used, then staff can verify identity documents, but transaction time increases and queues build up
Solution Approach 1:
The patent replaces manual mechanical verification processes with an automated optical scanning system. The scanner uses light sources (white light, UV, and IR) and a camera to capture images of the identity document, which are then processed by a server to verify authenticity. This substitution of manual inspection with automated optical-mechanical systems resolves the contradiction by maintaining verification reliability while dramatically reducing transaction time.
Solution Approach 2:
The system enables self-service verification where the scanner automatically performs document authentication without requiring staff intervention. The scanner captures images, the server processes them for authenticity verification, and results are communicated back automatically. This self-service approach eliminates the time-consuming manual verification process while maintaining reliable authentication through automated multi-spectral image analysis.
2Productivity
If simple barcode scanners are used, then extraction speed improves, but verification reliability decreases due to error risks
Solution Approach 1:
The patent extends verification from the simple 2D barcode reading to multi-dimensional spectral analysis. By incorporating UV and IR light sources in addition to white light, the system creates a multi-spectral verification approach that adds dimensional depth to the authentication process. This allows the system to maintain high extraction speed while significantly improving reliability by detecting authentication features that are invisible in standard visible light.
Solution Approach 2:
The verification system uses a composite approach combining multiple light sources (white light, UV, and IR) and multiple imaging modalities. This composite verification method processes information from different spectral dimensions simultaneously, enabling both rapid extraction and high reliability by cross-validating authentication features across multiple spectral bands rather than relying on a single barcode scan.
3Reliability
If advanced multi-spectral imaging systems are used, then verification reliability improves, but device complexity increases
Solution Approach 1:
The patent merges multiple light sources (white light, UV, and IR) and imaging functions into a single integrated scanner device. Rather than using separate systems for each spectral band, the invention combines them into one unified apparatus that captures multi-spectral images simultaneously or in rapid sequence. This merging approach maintains high verification reliability while reducing operational complexity compared to using multiple separate devices.
Solution Approach 2:
The scanner is designed as a universal multi-functional device that performs multiple verification functions using a single apparatus. It can scan barcodes, capture multi-spectral images for authentication mark verification, and extract text information all through one integrated system. This multi-functionality approach enables reliable authenticity verification without requiring complex separate systems for each verification method.

AI summary
The present disclosure relates to a method and a scanner for verifying the authenticity of identity documents (32). The scanner (10) comprises a slot (30) for receiving the identity document (32), at least one light source (18, 20, 22) and a camera (26) for acquiring images. The method detects, by means of the camera (26), the presence of the identity document (32) in the slot (30) of the scanner (10) and acquires three different images of the identity document (32) when it is illuminated with white light, UV light and IR light respectively. The images are encrypted and sent to an analyze server which in response to a request returns a second message comprising a verification report including textual information extracted from the identity document (32). The scanner (10) sends a first signal to an indicating means (24) for indicating the state of the authenticity of the identity document (32) and the textual information to a Point of Sale, POS, system (70) in response to that the identity document (32) has been verified.
