Solution Overview
Problem
Security vulnerabilities at self-service terminals, such as automated teller machines, including theft, unauthorized access, and covert observation of PIN entry, are not adequately addressed by existing technologies.
Innovation Solution
A self-service terminal equipped with an imaging device and processor for facial recognition, which activates or maintains a standby state based on facial recognition criteria, including detection of hidden faces and biometric features, to prevent unauthorized use and alert users to potential threats.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If facial recognition technology is implemented at self-service terminals, then security against unauthorized access and theft is improved, but device complexity increases
Solution Approach 1:
The imaging device serves multiple functions: capturing images for facial recognition, detecting hidden faces, and providing security monitoring. The processor performs multiple tasks including facial recognition, biometric feature extraction, and security control logic execution. This multi-functionality reduces the need for separate dedicated security components.
Solution Approach 2:
The patent replaces traditional mechanical security measures (such as physical barriers, manual monitoring, or card readers with physical locks) with an optical/electronic facial recognition system. The imaging device captures facial images and the processor analyzes biometric features to authenticate users and detect security violations, eliminating the need for complex mechanical security mechanisms.
2Reliability
If facial recognition and image processing are performed continuously, then security monitoring is improved, but energy consumption increases
Solution Approach 1:
The system performs facial recognition and image analysis periodically rather than continuously. The processor is configured to analyze images at specific trigger events such as when a user approaches the terminal, when the terminal is activated, or at predetermined time intervals. This periodic processing reduces energy consumption compared to continuous monitoring while maintaining effective security coverage.
Solution Approach 2:
The system performs preliminary image capture and basic facial detection before initiating full facial recognition analysis. The processor first determines whether an image contains a face and extracts basic biometric features before conducting comprehensive security assessments. This staged approach reduces computational energy consumption by performing only necessary analysis when conditions require it.
