Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Automated Teller Machines (ATMs) face security threats from skimming devices and PIN capture methods, as users are unable to easily detect modifications to magnetic card readers and cameras that capture PINs, leading to theft and fraud.

Innovation Solution

Implementing a camera-based system at ATMs that uses optical character recognition (OCR) to read bank card information from images captured by cameras, eliminating the need for magnetic card readers and enhancing security by verifying card information and PINs through a server, while also capturing user images for surveillance and authentication.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If magnetic card readers are used to read bank card information, then card reading functionality is provided, but the system becomes vulnerable to skimming device attacks

Engineering Contradiction:

ImprovesecurityVSAvoidskimming device vulnerability

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent replaces the magnetic card reader (mechanical/electromagnetic reading system) with a camera-based optical character recognition system. The camera captures images of the bank card, and OCR software extracts the card information, eliminating the magnetic stripe reading component that is vulnerable to skimming devices.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

Instead of directly reading magnetic information from the card, the system creates an optical copy (image) of the card using a camera. The card information is then extracted from this visual copy through OCR technology, rather than through direct magnetic contact that skimming devices exploit.

Inventive Principle:

Principle #26Copying

2Ease of operation

If traditional magnetic card readers are used, then card information can be read, but users cannot easily detect modifications or skimming devices

Engineering Contradiction:

Improveuser detection capabilityVSAvoidskimming device detection

Core Design Contradiction:

Ease of operationVSDifficulty of detecting and measuring

Solution Approach 1:

The camera serves multiple functions: it captures images for OCR-based card information reading, provides surveillance footage for security monitoring, and creates a visual record that can help users verify the authenticity of the ATM interface. This multi-functionality reduces the need for separate components that could be individually compromised.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Reliability

If cameras are added for OCR reading and surveillance, then security is enhanced, but device complexity increases

Engineering Contradiction:

ImprovesecurityVSAvoidsystem complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The camera system performs multiple security-related functions simultaneously: capturing card images for OCR processing, recording surveillance video for transaction monitoring, and providing visual documentation for fraud detection. This consolidates what would otherwise require separate devices into a single component.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system uses the same camera-captured images for multiple purposes without requiring additional specialized hardware. The OCR processing and surveillance functions both leverage the fundamental image capture capability, making the system more efficient despite enhanced functionality.

Inventive Principle:

Principle #25Self-service

AI summary

A method for improved security at automated teller machines (ATMs) comprising: capturing, by a first camera at an ATM, one or more images of a bank card; reading card information from the bank card by processing the one or more images of the bank card, wherein the card information comprises an account number and an expiration date; receiving, from an input device at the ATM, a personal identification number (PIN) entered by a user; sending a request to a server device to verify the card information and the PIN; and in response receiving a response from the server device, allowing the user to transact with the ATM.
