ABM Fraud Detection via Alarm-Triggered Video Archiving
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Automated banking machine (ABM) fraud, involving unauthorized magnetic stripe readers and spy cameras, poses significant security and monetary risks due to the inability to effectively detect and surveil suspicious activities in real-time.
Innovation Solution
A system comprising detectors for foreign device presence, surveillance cameras, and video recording devices that generate alarm notifications and archive video signals, with optional remote data processing for disabling the ABM and reviewing recorded files for suspicious activity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional surveillance methods are used without automated detection, then device complexity is reduced, but the timeliness and effectiveness of fraud detection deteriorates
Solution Approach 1:
The system employs automated detectors that autonomously monitor for foreign devices and trigger alarm notifications without requiring constant human surveillance. The video recording device automatically archives footage upon receiving alarm notifications, enabling the system to self-monitor and self-report fraud attempts, thereby improving detection reliability while maintaining manageable complexity
Solution Approach 2:
The patent replaces manual surveillance mechanisms with automated electronic detectors and digital video recording systems. The detectors electronically sense foreign devices and automatically generate alarm notifications, while the video recording device digitally archives surveillance footage, substituting mechanical human observation with electronic automation to enhance detection effectiveness
2Reliability
If video recording is continuously archived without selective archiving, then surveillance coverage is improved, but loss of time for data management and retrieval increases
Solution Approach 1:
The video recording device is configured to selectively archive video signals only upon receipt of alarm notifications from detectors. This preliminary conditioning ensures that surveillance footage is preserved in advance for specific fraud-related events, maintaining reliable surveillance coverage while avoiding the time loss associated with managing and reviewing continuous uninterrupted video data
Solution Approach 2:
The system extracts and archives only the relevant portions of video signals that correspond to alarm notifications indicating potential fraud. By separating and preserving only these critical segments rather than archiving all video data continuously, the system maintains comprehensive surveillance coverage for incidents while significantly reducing the time required for data management and retrieval
3Speed
If alarm notification is generated immediately upon detection, then response time is improved, but false alarms increase due to predetermined delays
Solution Approach 1:
The detector generates alarm notifications after a predetermined delay period following detection of a foreign device. This partial delay allows the system to confirm the presence of the foreign device before triggering the alarm, improving alarm accuracy by reducing false positives while still maintaining relatively fast response time to actual fraud attempts
Solution Approach 2:
The predetermined delay in alarm notification serves as a cushioning mechanism that prevents premature alarm generation. By waiting a predetermined period after detection before issuing the alarm, the system cushions against false alarms caused by transient detections or interference, thereby improving alarm accuracy while maintaining effective response time to genuine threats

AI summary
There is disclosed a method and system for surveillance of a suspect of automated banking machine (ABM) fraud. In an embodiment, there is a detector for detecting the presence of a foreign device targeting an ABM, the detector being configured to generate an alarm notification upon such detection. A plurality of surveillance cameras may be positioned to monitor an ABM and its surroundings. A video recording device is operatively connected to the detector and configured to archive the video signals recorded from the plurality of surveillance cameras upon receipt of the alarm notification. The detector may be configured to generate the alarm notification after a predetermined delay, and at least one of the archived recorded video signals should have a recorded length exceeding the predetermined delay for alarm notification in order to permit review of suspicious activity that generated the alarm notification.
