Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ATMs lose functionality during power and network outages, preventing customers from accessing their funds and exacerbating issues during emergencies, leading to widespread panic and operational challenges.
Innovation Solution
ATMs equipped with a secure memory device to store customer data and a backup battery mode that allow transactions to be authorized and completed offline, using locally stored data for authentication and transaction management, with power conservation modes to extend functionality during outages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If ATMs operate online with network connection, then transaction authorization and security are improved, but functionality is lost during network outages
Solution Approach 1:
The system performs preliminary action by pre-downloading and caching customer data, authentication information, and transaction protocols into the ATM's local memory before network outages occur. This enables the ATM to operate autonomously during outages using stored data, resolving the contradiction between online security and offline functionality.
Solution Approach 2:
The patent introduces an intermediary mechanism in the form of a local database and memory system that mediates between the ATM and the central banking network. This intermediary stores critical data locally, allowing transactions to be processed independently during network failures while maintaining security standards.
2Adaptability or versatility
If ATMs store customer data locally for offline operation, then offline functionality is improved, but data security risks increase
Solution Approach 1:
The system creates a controlled copy of customer data and authentication information in the ATM's secure memory, rather than storing actual sensitive data. This copy mechanism enables offline operation while minimizing security risks by storing only necessary transaction data rather than full customer profiles.
Solution Approach 2:
The patent applies local quality by implementing security measures tailored to the specific context of data storage in ATMs. This includes using encrypted local storage, access control mechanisms, and security protocols that are optimized for the ATM environment, making the stored data secure against local threats while enabling offline functionality.
3Duration of action of stationary object
If ATMs use backup battery mode during outages, then operational continuity is improved, but energy consumption increases
Solution Approach 1:
The system implements periodic action by monitoring battery charge levels and switching between power modes based on duration of outages. The ATM operates in high-power mode during initial outages when data caching is active, then transitions to power-saving mode after a predetermined period, reducing energy consumption while maintaining operational continuity.
Solution Approach 2:
The patent applies dynamics by making the power consumption characteristics adaptive rather than static. The ATM dynamically adjusts its power usage based on the duration and severity of outages, transitioning between operational modes to balance continuous service with energy conservation, thereby extending battery life during prolonged outages.
4Speed
If ATMs process transactions offline without network verification, then transaction speed is improved, but fraud detection capability deteriorates
Solution Approach 1:
The system performs preliminary action by pre-loading authentication protocols, customer verification rules, and fraud detection algorithms into the ATM's local memory. This enables rapid offline transaction processing while maintaining fraud detection capabilities through stored security protocols, eliminating the need for real-time network verification.
Solution Approach 2:
The patent implements feedback mechanisms in the form of local validation loops that continuously verify transactions against stored security protocols and customer data. The system provides immediate feedback on transaction authenticity and fraud indicators, maintaining detection accuracy while enabling offline high-speed processing through locally cached verification rules.
Data Source
AI summary
A device may receive customer data, and store the customer data in a secure memory device of the device. The device may implement a backup mode in which the device utilizes the customer data to authorize requests based on determining that the device lacks a network connection. The device may receive, when the device is in the backup mode, a request for currency that includes authentication information. The device, while in the backup mode, may authorize the request for currency based on comparing the authentication information and the customer data. The device may dispense currency based on a result of comparing the authentication information and the customer data. The device may store transaction data associated with dispensing of the currency to permit the transaction data to be transmitted when the network connection is restored.
