Access Control Token Generation for Visitor Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current control access systems face inefficiencies and user experience issues due to the manual management of visitor access, leading to delays, excessive network traffic, and performance degradation, particularly when handling a large number of temporary visitors with varied access requirements.
Innovation Solution
A resource allocation server and scheduling server optimize transactions by determining and allocating access resources and time periods, generating access tokens, and providing them to user devices for secure and efficient access to specific locations within a building, reducing the need for multiple transactions and improving system performance.

Engineering Contradiction Analysis
1Adaptability or versatility
If manual management of visitor access is implemented, then access control can be customized for each visitor, but system performance degrades and network traffic increases due to multiple transactions
Solution Approach 1:
The system pre-calculates and stores the ordered list of access control points and associated time periods in the database before visitors arrive. When a visitor needs access, the system performs a single transaction to retrieve this pre-computed information, eliminating the need for multiple sequential transactions during actual access control operations.
Solution Approach 2:
The system pre-generates and caches access tokens with embedded access information for multiple access control points. This allows visitors to access multiple locations without requiring repeated authentication transactions, significantly reducing network traffic and improving system response time.
2Reliability
If multiple transactions are performed with the security server for each visitor access, then access authorization can be verified, but network traffic increases and system responsiveness decreases
Solution Approach 1:
The system combines multiple access authorization transactions into a single database query by using the pre-computed ordered list of access control points. Instead of querying the server separately for each access control point, the system retrieves all necessary access information in one transaction, maintaining security verification while dramatically improving responsiveness.
Solution Approach 2:
The system creates and stores copies of access control information in the database, including the ordered list of access control points and associated time periods. This allows the system to serve multiple visitors with similar access patterns without repeatedly querying the security server, reducing network traffic and improving response time.
3Reliability
If custom access profiles are created for each visitor, then access security is maintained, but administrative burden increases significantly
Solution Approach 1:
The system uses a universal data structure (ordered list of access control points with time periods) that can accommodate different visitor types and access patterns. This single structure serves multiple functions: it defines access sequences, time constraints, and multiple access control points, eliminating the need to create and manage separate custom profiles for different visitor categories.
Solution Approach 2:
The system automatically computes and stores the ordered list of access control points based on visitor destination information, eliminating the need for administrators to manually configure access profiles. The system self-services by deriving access control sequences from destination data, maintaining security while reducing administrative burden.

AI summary
A method for a security system includes receiving a first location and a first time period, retrieving an access control tree having nodes associated with locations and edges coupling nodes, wherein a first node represents the first location and a second node represents a building entry, traversing the access control tree from the second node to the first node to determine an ordered list of nodes and associated time periods, storing the ordered list of nodes and an identifier associated with a user, providing to a smart device a token associated with a requested access control point, when a requested node is within the first ordered list of nodes, and authorizing with the requested access control point a physical action visible to the user in response to the requested token.
