Biometric Safe Deposit Box Access System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional safe deposit boxes and teller drawers require cumbersome and time-consuming procedures involving multiple keys and bank employee participation for access, which are inefficient and prone to errors.
Innovation Solution
A method using electronic locks with biometric authentication, where internal codes are recorded on electronic keys and transferred to a data processing machine for authorized access, allowing simultaneous dual access with biometric identification and key retention units to manage key programming and release.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional mechanical key systems are used for safe deposit boxes, then security is maintained through dual-key requirements, but access procedures become cumbersome and time-consuming requiring bank employee participation
Solution Approach 1:
The patent replaces the traditional mechanical key system with an electronic lock system that uses biometric authentication (fingerprint scanning) and electronic keys. The electronic lock reads unique internal codes from electronic keys via RFID or similar technology, eliminating the need for physical key manipulation and bank employee verification, thereby reducing access time while maintaining security through automated authentication protocols
Solution Approach 2:
The system enables customers to access their safe deposit boxes independently without requiring bank employee participation. The electronic lock autonomously verifies customer identity through biometric scanning and validates electronic keys automatically, allowing customers to open, access, and close their boxes during bank hours without human intervention, thus eliminating the time loss associated with employee involvement
2Reliability
If multiple mechanical keys are required for access, then security is enhanced through distributed key control, but operational complexity increases requiring coordination between multiple parties
Solution Approach 1:
The electronic key serves multiple functions: it contains the unique internal code for authentication, acts as a portable credential stored on RFID tags or smart cards, and enables both opening and closing operations. This single multi-functional electronic key replaces the need for multiple mechanical keys and simplifies the access procedure while maintaining the security principle of distributed key control through electronic credential management
3Productivity
If electronic locks with biometric authentication are implemented, then access efficiency is improved through automated verification, but key management complexity increases requiring programming and release mechanisms
Solution Approach 1:
The bank employee acts as an intermediary in the key management process by programming electronic keys with the necessary internal codes and releasing them to authorized customers. This centralized key management approach, while adding some complexity, enables rapid automated access for customers through biometric verification and electronic code validation, significantly improving access speed compared to traditional mechanical systems

AI summary
A method for commissioning a collection of electronic locks by inserting the same electronic key into each of the locks and recording in the electronic key an internal code unique to that lock which identifies the lock and is needed to open the lock and a method for biometrically permitting controlled secure access to a container having one of the commissioned electronic locks.
