Pseudo-Reader Access Control for Multi-Tenant Credential Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current access control systems in multi-tenant buildings face challenges in managing and integrating different credential systems, leading to issues such as outdated databases, aesthetically displeasing and confusing portal setups, and increased costs due to the need for multiple vendors and complex diagnostics when one system fails.
Innovation Solution
A networked access control system that employs a Pseudo-Reader to generate impulses compatible with proprietary credential reader inputs, allowing for immediate updates and authorization without exposing the entire database, thereby compartmentalizing security and reducing the need for extensive modifications or database sharing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If each entity mounts their own credential reader and control system on building portals, then each entity can control access to their private areas independently, but the building portals become aesthetically displeasing and confusing with multiple credential readers, and integration becomes difficult and expensive
Solution Approach 1:
The system divides the access control functionality into two segments: a central building management system that handles common areas and resources, and entity-specific access control systems that handle private areas. This segmentation allows each entity to maintain independent control over their private spaces while the building management system manages common resources, eliminating the need for multiple credential readers at each portal.
Solution Approach 2:
The patent introduces an intermediary interface layer between the building management system and entity access control systems. This intermediary enables communication and coordination between different systems without requiring direct integration, allowing credential validation and access decisions to be made seamlessly at a single reader location while maintaining the independence of each entity's access control system.
2Ease of operation
If building management issues their own credentials to all authorized people, then access to common spaces can be controlled, but the building's database becomes stale with outdated information and terminated individuals still have access
Solution Approach 1:
The system implements a feedback mechanism where entity access control systems continuously communicate credential validity status to the building management system. When an entity updates their authorized personnel list or terminates an individual's access, this information is fed back to the building management system, ensuring the central database remains current without requiring manual updates or synchronization.
Solution Approach 2:
The patent establishes continuous communication between entity access control systems and the building management system, ensuring that credential database updates occur in real-time or near real-time. This continuous action prevents database staleness by maintaining an ongoing exchange of access authority information rather than relying on periodic manual synchronization.
3Adaptability or versatility
If one of the controlling systems fails, then building resources may be locked or unlocked at the wrong times, but with multiple vendors involved, the diagnostic procedure and vendor coordination slows the repair process
Solution Approach 1:
The intermediary interface layer acts as a mediator that standardizes communication between different vendor systems and the building management system. This intermediary layer includes standardized diagnostic interfaces and error reporting mechanisms that allow technicians to diagnose issues across multiple systems through a unified approach, reducing the need to coordinate between multiple vendors and speeding up the repair process.

AI summary
In setting where a number of entities share a common resource and where those entities wish to exclude unauthorized individuals yet desire partitioned access for a set of individuals from each entity, a system integrates a plurality of sets of authorized credentials from a plurality of entities using networking techniques to allow partitioned access to common resources shared by those entities.
