Access Control Triplet Verification for Context-Aware Entry
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing access control systems fail to adequately verify that a user's credentials align with their current operational context, such as the equipment they are using and the nature of the load they are carrying, leading to potential unauthorized access.
Innovation Solution
Implementing an access control triplet system that combines user access rights with equipment and temporary token data to ensure accurate access control, including periodic verification to maintain validity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional access control systems only verify user credentials, then the access control process is simple and fast, but the security is insufficient because it cannot verify whether the user is operating the correct equipment or carrying appropriate loads
Solution Approach 1:
The patent merges three separate access control dimensions into a unified triplet verification system: (1) user credentials, (2) equipment identifiers, and (3) load characteristics. This combination creates a more comprehensive security check that verifies not only who the user is but also what equipment they are operating and what load they are carrying, thereby resolving the contradiction between security and simplicity.
Solution Approach 2:
The access control reader serves as an intermediary device that collects and verifies all three triplet components (user credential, equipment identifier, load characteristic) before granting access. This intermediary mechanism enables comprehensive verification without requiring complex changes to the entire access control infrastructure, as the reader mediates between the existing credential system and the new equipment/load verification requirements.
2Reliability
If access control systems verify multiple factors (user, equipment, load), then the security and context-awareness improve, but the verification process becomes more complex and time-consuming
Solution Approach 1:
The system performs preliminary verification of the access control triplet by checking whether the combination of user credential, equipment identifier, and load characteristic is valid before allowing access. This preliminary check ensures that all three components are present and consistent with each other, enabling fast rejection of invalid access attempts while allowing valid ones to proceed smoothly, thus reducing overall verification time.
Solution Approach 2:
The patent replaces manual or mechanical verification processes with automated electronic verification of the access control triplet. The access control reader automatically reads and validates the user credential, equipment identifier, and load characteristic through electronic communication, substituting time-consuming manual checks with rapid automated verification, thereby reducing access verification time while maintaining comprehensive security.
Data Source
AI summary
Techniques for modifying user access rights are provided. Access rights of the user are retrieved from an access control system token associated with the user. Access rights of a piece of equipment currently being operated by the user are retrieved from an access control system token associated with the piece of equipment. Access rights of a temporary token currently associated with the piece of equipment are retrieved from an access control system token associated with temporary token. The access rights of the user, the piece of equipment, and the temporary token currently associated with the equipment are combined to create an access control triplet. It is determined if the user is allowed to pass through an access control point based on the access control triplet.
