Electronic Key Module for Safety Deposit Box Access Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing safety deposit box systems lack effective access control, allowing unauthorized users to potentially access and tamper with other customers' boxes, leading to security issues and difficulties in detecting unauthorized access.
Innovation Solution
A system featuring a wireless RFID indicator and an electronic key module that controls access to safety deposit boxes, allowing authorized users to access their boxes on a self-service basis by verifying identity and uniquely identifying each box, while maintaining records of usage and potential improper activities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a guard key is held by the bank and used to open the guard lock on safety deposit boxes, then access control is provided, but labor intensity for bank employees increases and self-service access is limited
Solution Approach 1:
The system enables customers to independently access their safety deposit boxes using electronic keys without requiring bank employee assistance. The electronic key contains customer-specific data that automatically authenticates with the bank's system, allowing the customer to open their designated box alone.
Solution Approach 2:
The traditional mechanical guard key system is replaced with an electronic key system that uses electronic authentication and data verification. The electronic key communicates with the bank's computer system to verify customer identity and authorize access, eliminating the need for manual key handling by employees.
2Productivity
If guard keys are placed in fixed unlocked condition to enable self-service, then employee involvement is reduced, but security against unauthorized access deteriorates
Solution Approach 1:
The system changes the authentication parameter from a universal mechanical key to customer-specific electronic data stored in individual electronic keys. Each electronic key contains unique customer identification data that must be verified by the bank's system, providing both convenience and security through data-based authentication rather than physical key uniformity.
Solution Approach 2:
The electronic key system incorporates feedback mechanisms where the bank's computer system verifies the customer's identity and authorization status before granting access. The system provides immediate feedback by confirming or denying access based on the electronic key's data, ensuring security while maintaining self-service efficiency.
3Device complexity
If traditional key locks are used without electronic tracking, then simplicity is maintained, but ability to detect and record unauthorized access is reduced
Solution Approach 1:
The electronic key acts as an intermediary between the customer and the safety deposit box, incorporating a microprocessor and data storage capabilities. This intermediary device communicates with the bank's computer system to verify authorization, creating a detectable authentication trail that records legitimate access attempts and can identify unauthorized use.
Solution Approach 2:
The simple mechanical lock system is enhanced by integrating electronic authentication components into the key itself. The electronic key contains a microprocessor that interacts with the bank's system, replacing the passive mechanical key with an active electronic authentication device that provides detection and recording capabilities.
4Reliability
If manual verification of customer identity is performed, then security is maintained, but time consumption and labor intensity increase
Solution Approach 1:
The customer's identity verification data is pre-stored in the electronic key during key issuance. When accessing the safety deposit box, the pre-stored data is automatically presented and verified by the bank's system, eliminating the need for time-consuming manual verification processes during each access event.
Solution Approach 2:
Manual identity verification by bank employees is replaced with automated electronic verification. The electronic key's stored data is automatically read and verified by the bank's computer system, substituting human judgment and manual checking with rapid electronic data comparison that occurs in seconds.

Data Source
AI summary
A system for use in banking operates responsive to data included in data bearing records. The system is suitable for securing the contents in safety deposit boxes or similar locked receptacles, and selectively permits access to key locks only to individuals who have been determined to be authorized to have such access. Each safety deposit box or other receptacle includes a door (16) with at least one key lock (22, 24) thereon. An assembly (26) is installed on the preexisting door to limit access to a key lock to an authorized person. The assembly includes a body (32) that is held in a blocking position by a cover lock. A selectively programmable data bearing electronic key module (28) is operative to change the condition of a selected cover lock from a latched to an unlatched condition. Electronic key modules are appropriately programmed to enable the particular user access to key locks on a particular safety deposit box, through operation of a customer station (126).
