Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The management and security of Automated Teller Machines (ATMs), especially those deployed away from banking centers or in remote areas, require enhanced security measures to prevent unauthorized access, as existing solutions are inadequate.
Innovation Solution
An ATM Electronic Lock System utilizing a Mobile Communication Network, a Mobile Communication Terminal, an ATM Management Center Control and Management Subsystem, and an ATM Electronic Lock Subsystem, which includes a Master Control Module, Personal ID Authentication Module, Controller Encryption and Decryption Module, and a Lock Actuating Mechanism, using one-time codes and biometric authentication to securely manage and control access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an electronic lock is added to an ATM to enhance security, then the security of the ATM is improved, but the device complexity increases
Solution Approach 1:
The patent introduces a Management Center as an intermediary between the ATM and the electronic lock system. The Management Center handles code generation, distribution, and verification, allowing the ATM itself to remain relatively simple while still achieving high security through the distributed control architecture. The lock subsystem communicates with the Management Center rather than requiring complex local authentication logic at the ATM.
2Reliability
If a Management Center is introduced to control the electronic lock system, then the security management is improved, but the system complexity increases
Solution Approach 1:
The Management Center implements self-service mechanisms by automatically generating one-time codes, distributing them to authorized users, and verifying them against the lock subsystem. The system performs automatic authentication, logging, and state management without requiring manual intervention for each locking/unlocking operation, thereby improving security management while keeping operational complexity manageable.
Solution Approach 2:
The system incorporates feedback mechanisms where the Management Center continuously monitors the lock state, authentication attempts, and system events. This feedback enables dynamic security management, allowing the center to detect anomalies, log activities, and maintain accurate system state information, thereby improving security management capability.
3Reliability
If one-time codes are used for authentication, then the security is improved, but the loss of time increases due to code generation and verification
Solution Approach 1:
The Management Center generates and distributes one-time codes in advance to authorized users before they need to access the ATM. Users receive codes via mobile devices or other communication channels, so when they arrive at the ATM, the authentication process is already prepared. This preliminary action reduces on-site authentication time while maintaining the security benefits of one-time codes.

AI summary
A method for ATM Electronic Lock System comprising the steps: (a) a user using ATM card and entering PIN in an ATM Electronic Lock Subsystem, (b) the ATM Lock System authenticating the user, (c) generating a RND and Local One Time Code (LOTC) with the user's personal ID, Equipment ID, (d) displaying the RND to the user and the user sending the RND to ATM management center via mobile device, (e) the Management Center authenticating the user and generating a Management Center One Time Code (MC-OTC) and sending the MC-OTC to the user's mobile device, (f) the user entering the MC-OTC to the ATM Electronic Lock Subsystem, (g) the ATM Electronic Lock Subsystem comparing the MC-OTC with LOTC, and sending unlock command to unlock the ATM Electronic Lock System to allow user to access the ATM if the MC-OTC matches the LOTC, otherwise, the ATM Electronic Lock System remains locked.
