Transaction Security Apparatus Using Biometric Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for securing financial transactions and wireless communication devices lack real-time authorization and notification, leading to widespread theft and fraudulent use of credit cards, debit cards, currency cards, savings accounts, checking accounts, and cellular telephones, resulting in significant financial losses and inconvenience for users.
Innovation Solution
A system comprising a point-of-sale terminal with a camera and microphone, connected to a central processing computer via a communication system, which captures and verifies the identity of individuals engaging in transactions through image and audio recordings, and notifies cardholders or account owners in real-time of potential unauthorized activities, allowing for immediate cancellation of transactions and deactivation of accounts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If real-time authorization and notification systems are implemented, then security against fraudulent use is improved, but device complexity and operational costs increase
Solution Approach 1:
The patent introduces a central processing computer as an intermediary between the point-of-sale terminal and the cardholder's communication device. This mediator coordinates the real-time authorization process, manages transaction data, and facilitates communication between all parties, thereby implementing security without requiring complex modifications to individual components.
Solution Approach 2:
The system implements real-time feedback by notifying the cardholder immediately upon transaction initiation through a communication device (such as a cellular telephone). The cardholder can respond to authorize or reject the transaction before it completes, creating a closed-loop feedback system that enhances security while maintaining operational simplicity.
2Reliability
If real-time notification to cardholders is implemented, then detection of unauthorized use is improved, but loss of time for transaction processing increases
Solution Approach 1:
The system performs preliminary action by notifying the cardholder in advance of the transaction completion before the transaction is finalized. This allows the cardholder to review and authorize the transaction proactively, ensuring detection of unauthorized use without delaying the overall transaction process, as the notification and response occur in parallel with settlement procedures.
3Reliability
If identity verification through camera and microphone is implemented, then reliability of authorization is improved, but device complexity and cost increase
Solution Approach 1:
The patent utilizes a cellular telephone as a multi-functional device that serves both as the cardholder's notification device and as an identity verification tool. The telephone's existing camera and microphone capabilities are leveraged for biometric verification, eliminating the need for separate specialized equipment and reducing overall system complexity while maintaining high authorization accuracy.
Data Source
AI summary
An apparatus including an input device for inputting transaction information regarding a transaction on an account involving an individual, a camera for obtaining a photograph of the individual which photograph is stored as a digital photograph file, a processing device which processes information regarding the transaction and generates a message containing information regarding the transaction and the digital photograph file, and a transmitter which transmits the message to a communication device associated with an individual account holder. The message is transmitted to the communication device via, on, or over, a communication network and the message is transmitted to the communication device independently of any processing of the transaction by a central transaction authorization processing computer.
