Lighting Component Access Control via Username Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Commissioning and setting up access control in smart lighting systems is tedious due to the need for manual configuration of access rights for multiple devices and users, especially as future systems will implement more stringent access limitations.
Innovation Solution
A system and method that automatically prepopulate access rights in lighting systems by matching component names (e.g., room names, user names) to determine user access, using a processor to analyze component and user information, and store these rights in memory for easy access control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual configuration of access rights is implemented for each device and user, then access control security is improved, but commissioning time and complexity increase
Solution Approach 1:
The system performs preliminary actions by automatically generating access rights configurations before manual configuration is required. The processor analyzes device names and user names in advance, pre-populates access rights matrices, and prepares default access configurations that are ready for user confirmation, thereby eliminating the need for time-consuming manual setup while maintaining security requirements
2Loss of time
If automated access rights configuration is implemented by matching names, then commissioning time is reduced, but precision of access control may deteriorate
Solution Approach 1:
The system implements feedback mechanisms where the automatically generated access rights configuration is presented to users for review and confirmation. Users can verify that the automated name-matching results are correct, provide feedback for corrections, and confirm the final configuration. This feedback loop ensures that automated generation maintains high precision by allowing human verification before final deployment
Solution Approach 2:
The system performs partial automation by automatically generating access rights only for cases where name matching provides clear results, while leaving ambiguous or complex cases for manual configuration. This partial action approach ensures high precision by combining automated efficiency for straightforward cases with manual verification for edge cases, rather than attempting full automation that might compromise accuracy
3Reliability
If access control rules are strictly enforced for multiple devices and users, then security is improved, but system complexity increases
Solution Approach 1:
The system implements a universal access rights matrix that serves multiple devices and users simultaneously through a single standardized configuration structure. The same name-matching algorithm and access rights format apply across all devices and users in the lighting system, eliminating the need for device-specific or user-specific custom configurations. This multi-functional approach maintains strict security enforcement while reducing overall system complexity through standardization

AI summary
A system (1) is configured to obtain component information specifying names (51-53) of components (31-33) of the lighting system, obtain user information specifying user names (59), look up a component name of a component of the lighting system in the component information, determine access rights for the component by determining whether the component name comprises a user name of the user names, and store the access rights in a memory. The system is further configured to receive a request to access the component, the request identifying a requestor (49), determine, based on the access rights for the component stored in the memory, whether the requestor is allowed to access the component, and access the component upon determining that the requestor is allowed to access the component.
