Authentication Device Preventing Further Access After Initial Permission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing authentication systems fail to effectively prevent further access to services after initial access has been inadvertently permitted by a malicious user, compromising security.
Innovation Solution
An authentication device sends access notifications to a user's device, allowing users to approve or deny access requests, and provides instructions to service providers to prevent further access if necessary, thereby enhancing security measures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If access notifications are sent to allow users to approve or deny access requests, then user control over access is improved, but system complexity increases
Solution Approach 1:
The authentication system is segmented into distinct components: an authentication device that sends notifications, a user device that receives and responds to notifications, and service providers that enforce access decisions. This segmentation allows each component to have a specialized function, improving reliability while managing complexity through modular design.
Solution Approach 2:
The authentication device acts as an intermediary between the user device and service providers. It receives access requests from service providers, forwards notifications to the user device, and relays user decisions back to service providers. This intermediary role simplifies the overall system architecture by centralizing the authentication logic.
2Object-affected harmful factors
If the system provides instructions to service providers to prevent further access after initial access is permitted, then security against malicious users is improved, but device complexity increases
Solution Approach 1:
The system performs preliminary authentication by sending access notifications to the user device before granting access to service providers. This preliminary action allows users to approve or deny access in advance, preventing unauthorized access before it can occur. The system also provides instructions to service providers to prevent further access if malicious activity is detected, addressing security concerns proactively.
3Reliability
If multiple authentication steps are required including sending notifications and receiving responses, then access security is improved, but operation time increases
Solution Approach 1:
The authentication process uses periodic actions where the authentication device sends notifications at specific intervals and waits for user responses. This structured periodic interaction ensures security while managing the time required for authentication. The system can implement timeout mechanisms and retry logic to balance security requirements with user convenience.
Data Source
AI summary
A device may receive information associated with a user request to access a service using a first device. The information may include a user credential. The device may identify a second device associated with the user credential. The device may provide a notification, associated with the user request to access the service, to the second device, and may receive a response from the second device. The response may indicate to permit access to the service. The device may provide an instruction to permit the first device to access the service. The device may provide information that identifies services for which access has been permitted for the user credential. The device may receive an indication to prevent further access, for the user credential, to at least one service. The device may provide an instruction to prevent further access to the at least one service for the user credential.
