Refuge Space Access Using Decentralized Mobile Identity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for providing refuge spaces in vehicles or buildings are inefficient and require extensive registration with multiple servers, making it impractical for a large number of people to access them in emergency situations.
Innovation Solution
A method utilizing a mobile terminal to trigger a refuge request via wireless communication, checked via a decentralized identity system, unlocking access to objects equipped with a refuge mode using a distributed ledger technology for secure and efficient access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a centralized registration system is used for refuge space access, then access authorization can be managed, but the on-boarding process becomes complex and time-consuming for large numbers of people
Solution Approach 1:
A decentralized identity system acts as an intermediary between the mobile terminal and the refuge space access system. The digital identity stored in the mobile terminal serves as a self-contained credential that can be verified by the communication unit without requiring centralized registration, thus simplifying the on-boarding process while maintaining reliable access control
Solution Approach 2:
The mobile terminal autonomously stores and presents digital identity credentials without requiring external registration services. The identity verification is performed locally by the communication unit through wireless communication, enabling users to access refuge spaces independently without complex centralized on-boarding procedures
2Reliability
If extensive registration with multiple servers is required, then access control can be enforced, but the time required for on-boarding increases significantly
Solution Approach 1:
The digital identity is pre-stored in the mobile terminal before any refuge space access is needed. This preliminary setup eliminates the need for time-consuming registration processes at the point of use, allowing immediate access verification through wireless communication when emergency situations arise
Solution Approach 2:
The access authorization capability is extracted from centralized server systems and embedded directly into the mobile terminal as a digital identity. This extraction removes the dependency on multiple servers and complex registration processes, enabling rapid access control through local verification
3Productivity
If access is granted to any mobile terminal with digital identity, then quick access is enabled, but unauthorized usage risk increases
Solution Approach 1:
The system provides feedback through tamper-proof documentation of access events in a database system. Each access request, verification result, and grant of access is recorded, creating an audit trail that enables monitoring and detection of unauthorized usage patterns while maintaining quick access for legitimate users
4Ease of operation
If a decentralized identity system is used, then on-boarding effort is minimized, but system complexity in identity management increases
Solution Approach 1:
The decentralized identity system allows mobile terminals to autonomously store and manage digital identities without requiring enrollment in centralized registration systems. Users can independently possess valid digital identities that are recognized by the refuge space access system, eliminating complex on-boarding procedures while distributing identity management across the network
Data Source
AI summary
A method for providing a refuge space in an object for a person seeking shelter involving triggering a refuge request via an application on a mobile terminal. A communication unit in the object receives the refuge request via wireless communication. The refuge request is saved in a database system and is anonymously checked based on the digital identity of the mobile terminal. The checking comprises a search in an access authorization system. After a successful positive checking, access to the refuge space is released and the object is switched to a refuge mode. The checking and the release are documented in the database system.
