ATM Authentication Media Capture via Beam Splitter
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current ATM systems lack multi-factor authentication capabilities, making them vulnerable to unauthorized access as they primarily rely on PIN numbers and do not have the hardware or software to implement additional verification methods.
Innovation Solution
Implementing a multi-factor authentication system that uses a combination of PIN verification, authentication media items (such as barcodes or QR codes), user image recognition, and historical transaction data to authenticate users, with minimal modifications to existing ATM terminals, utilizing a beam splitter to capture authentication media items outside the camera's field of view.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If ATM terminals use only PIN numbers for authentication, then the system is simple to operate and implement, but security is weak and vulnerable to unauthorized access
Solution Approach 1:
The authentication process is divided into multiple independent factors: PIN number verification, authentication media item verification (barcode/QR code), and user image recognition. Each factor operates as a separate verification module, allowing the system to achieve multi-factor authentication without requiring a single complex unified system. The ATM terminal can selectively implement different combinations of these segmented authentication modules based on security requirements.
Solution Approach 2:
The ATM terminal is designed with multi-functional authentication capabilities that can handle multiple types of verification methods through a unified interface. The same terminal hardware and software platform supports PIN verification, barcode/QR code scanning, and facial recognition, eliminating the need for separate dedicated systems for each authentication method and reducing overall system complexity.
2Reliability
If ATM terminals implement multi-factor authentication with multiple verification methods, then authentication security is improved, but hardware and software complexity increases
Solution Approach 1:
A centralized authentication server acts as an intermediary between the ATM terminal and various verification systems. The server handles the complex logic of coordinating different authentication methods, verifying credentials, and making authentication decisions. This intermediary approach allows the ATM terminal to maintain relatively simple hardware and software while achieving robust multi-factor authentication through the server's sophisticated processing capabilities.
Solution Approach 2:
The system uses digital copies of authentication media items (barcodes, QR codes) and user images stored in databases rather than requiring physical verification equipment for each factor. The authentication server stores and compares digital representations of authentication credentials, eliminating the need for complex physical verification hardware at the ATM terminal and reducing overall system hardware requirements.
3Adaptability or versatility
If the ATM terminal camera captures authentication media items outside its field of view using a beam splitter, then authentication functionality is extended, but optical system complexity increases
Solution Approach 1:
The beam splitter serves as an optical intermediary that redirects light paths to enable the camera to capture authentication media items positioned outside its direct field of view. This optical mediator allows the existing camera hardware to perform extended functionality without requiring additional cameras or complex mechanical positioning systems, achieving versatility with minimal added complexity.
Solution Approach 2:
The beam splitter introduces a new spatial dimension to the camera's field of view by redirecting light at angles that allow capture of media items positioned in previously inaccessible areas. This optical dimensionality change enables the camera to verify authentication media held at various angles and positions without requiring physical movement of the camera itself, extending capture capability through optical geometry rather than mechanical complexity.

Data Source
AI summary
A system for verifying a user operating an Automated Teller Machine (ATM) sends an authentication media item to a user device associated with the user when the ATM receives a transaction request. The system receives, from the ATM, a first image of the authentication media item when the authentication media item is presented to the ATM. The system compares the first image of the authentication media item with a second image of the authentication media item stored in a user profile associated with the user. The system extracts a first unique code from the first image of the authentication media item, and a second unique code from the second image of the authentication media item. The system determines whether the first unique code corresponds to the second unique code. The system approves the transaction request if it is determined that the first unique code corresponds to the second unique code.
