Identity Verification System Using Facial and Document Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional methods for verifying user identity, especially for new customers, require physical presence and are limited by the capabilities of existing ATMs and mobile devices, which restricts the utilization of these devices for identity verification beyond specialized banking functions.
Innovation Solution
A system and method utilizing facial recognition and optical character recognition (OCR) to verify a user's identity by comparing a live facial image with a photograph on an identity document, allowing verification without physical presence through mobile devices or ATMs, leveraging camera-equipped devices and interactive user interfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If in-person verification at physical locations is required, then identity verification reliability is improved, but user convenience and accessibility deteriorate
Solution Approach 1:
The patent replaces the mechanical system of in-person physical presence with an optical and computational system. Cameras capture images of identity documents and facial features, then computational algorithms verify authenticity and match faces. This substitution maintains verification reliability while enabling remote operation, thus improving user convenience without sacrificing security.
2Device complexity
If ATMs are limited to existing customer banking services, then device functionality is simplified, but device utilization and service accessibility deteriorate
Solution Approach 1:
The patent transforms the ATM from a single-function banking device into a multi-functional identity verification platform. By integrating camera systems, document recognition software, and facial analysis capabilities, the ATM can now serve both existing customers for banking transactions and new customers for identity verification and account opening. This multi-functionality increases device utilization while maintaining operational simplicity through automated processes.
3Measurement precision
If new customers must visit bank branches during business hours, then identity verification accuracy is improved, but time efficiency and accessibility deteriorate
Solution Approach 1:
The patent implements preliminary action by pre-configuring ATMs with identity verification capabilities, document recognition databases, and facial matching algorithms before customer arrival. The system is prepared to immediately verify identities without requiring human reviewer availability. This preliminary setup maintains verification accuracy while enabling 24/7 operation, thus eliminating the need for customers to visit during limited business hours and significantly improving time efficiency.
Data Source
AI summary
A system receives an image including a live facial image of the user and an identity document including a photograph of the user. Moreover, the system calculates a facial match score by comparing facial features in the live facial image to facial features in the photograph. The system recognizes data objects and characters in the identity document using optical character recognition (OCR) and computer vision, and then identifies, based on the recognized data objects and characters, a type of the identity document. Further, the system calculates a document validity score by comparing the recognized characters and data objects to character strings and data objects known to be present in the identified type of the identity document. Additionally, the system determines and outputs the user's identity verification status based on comparing the facial match score to a facial match threshold and comparing the document validity score to a document validity threshold.
