ATM Image Rebuild via Network File Retrieval
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
ATMs often require manual intervention to restore operation after an operating system crash due to corrupted key system files, which disrupts uptime and increases maintenance costs.
Innovation Solution
Implementing mechanisms for automatic verification and replacement of key system files, including a boot process that downloads and verifies re-imaging protocols, and retrieves viable copies from nearby machines via network connections if necessary, to rebuild the machine image.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual intervention is used to restore ATM operation after operating system crash, then the ATM can be restored to operational state, but the restoration process requires human involvement which increases maintenance costs and reduces productivity
Solution Approach 1:
The ATM system automatically detects corrupted key system files, retrieves backup copies from secondary storage or network locations, and restores the machine image without requiring manual human intervention. The system performs self-diagnosis and self-repair by comparing current system files against known good versions and automatically replacing corrupted files.
2Reliability
If manual intervention is required to restore ATM operation, then restoration can be performed, but the ATM experiences extended downtime which loses revenue and reduces service availability
Solution Approach 1:
The system maintains pre-prepared backup copies of key system files and machine images in secondary storage or network locations before corruption occurs. When corruption is detected, the system immediately retrieves and applies the pre-prepared backup, eliminating the time required for manual file retrieval and system reconstruction.
3Speed
If simple reboot is performed after operating system crash, then the ATM can be quickly restarted, but if key system files are corrupted the restoration fails and requires complex manual intervention
Solution Approach 1:
The system implements a feedback mechanism that monitors the results of automatic restoration attempts. If the automatic restoration using backup files fails to resolve the issue, the system detects this failure and triggers an alert for manual intervention. This feedback loop allows the system to quickly try automatic recovery and only escalate to manual processes when necessary.

AI summary
A method and apparatus for rebuilding an ATM computer image in an Automatic Teller Machine (ATM) is provided. The computer of the ATM is configured to depend on key system files. The key system file may be used to recreate a viable machine image in the event that the ATM “crashes” or some files become corrupted. If key system files are found cannot be verified upon a reboot, a copy of key system file is sought. The ATM first searches for the key system files in ATMs that are connected to a common switch. If the nearby ATMs do not have a copy of key system files than a succession of searches are made across local area networks and wide area networks. Key system files may reside on similar ATMs, dissimilar ATMs, servers, terminals and network drives. If key system files can be located then the ATM may automatically restore a viable machine image and reboot. Otherwise manual intervention is required.
