Temporary Password Generation for Secure Mobile Access Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing security systems lack flexibility, requiring users to either deactivate the alarm system or share access codes with service personnel, which can compromise security if the code is misused.
Innovation Solution
A security system that allows authorized users to generate and transmit temporary passwords with usage restrictions to portable devices, enabling secure and controlled access for service personnel without fully disarming the system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the alarm system is deactivated to allow service personnel entry, then ease of operation is improved, but security is worsened as the area becomes unprotected
Solution Approach 1:
The access control is segmented into temporary passwords with specific constraints (time limits, usage counts, specific zones) rather than a single master code. This allows the system to be divided into multiple controlled access instances, each with limited scope, resolving the contradiction by providing ease of operation through simple temporary codes while maintaining security through granular control limits
2Ease of operation
If the access code is shared with service personnel, then ease of operation is improved, but security is worsened due to potential code misuse
Solution Approach 1:
The system generates disposable temporary passwords that are valid only for limited periods and usage counts. Each temporary password is essentially a single-use or limited-use credential that becomes invalid after expiration, eliminating the long-term security risks associated with sharing permanent access codes while maintaining operational ease
3Reliability
If temporary passwords with restrictions are implemented, then security is improved, but device complexity is worsened
Solution Approach 1:
The temporary password generation system serves multiple functions: it creates time-limited codes, usage-count-limited codes, zone-specific codes, and can be integrated with mobile devices for distribution. This multi-functionality consolidates various security control mechanisms into a single system, improving security while minimizing the increase in overall device complexity
