Mobile Access Control with Dynamic Wireless Range Permissions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional access control systems fail to provide secure and user-friendly access control by allowing unauthorized access to secured areas due to fixed access ranges for all users, lacking the ability to dynamically adjust access permissions based on user identity and context.
Innovation Solution
A mobile access control system that includes a credential management server, access control device, and mobile device, enabling secure access control through wireless communication, credential verification, and dynamic range adjustment based on user identity and distance, with features like QR code scanning and contactless operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional access control systems use fixed access ranges for all users, then device complexity is reduced and ease of operation is improved, but security is compromised because unauthorized users can access secured areas
Solution Approach 1:
The access control system dynamically adjusts the wireless communication range based on user identity. Different users are assigned different access ranges (first, second, or third range) according to their credentials, allowing the system to adapt access permissions in real-time without requiring complex manual configuration for each user
Solution Approach 2:
The system changes the communication parameter (wireless communication range) based on user credentials. The credential management server determines which range to assign to each user, enabling flexible security control by modifying system parameters dynamically rather than using fixed configurations
2Reliability
If conventional systems allow any registered user to access the secured area within the predefined range, then ease of operation is improved, but security deteriorates because interview candidates and employees have the same access permissions
Solution Approach 1:
Different users receive different local access permissions based on their identity. The system assigns specific wireless communication ranges (first range for employees, second range for contractors, third range for interview candidates) tailored to each user's security clearance level, ensuring that each user has appropriate access rights for their specific role
Solution Approach 2:
The access control system segments users into different categories with different access ranges. By dividing the user base into groups with varying permission levels and assigning them different wireless communication ranges, the system provides differentiated access control without complicating the user experience
3Ease of operation
If the system uses short range wireless communication for contactless access, then ease of operation is improved and hygiene is enhanced, but the wireless communication range must be precisely controlled to prevent unauthorized access
Solution Approach 1:
The credential management server acts as an intermediary that verifies user credentials and determines the appropriate wireless communication range before granting access. This intermediary layer ensures that contactless access is both convenient and secure by validating user identity and assigning appropriate access parameters

AI summary
Embodiments herein disclose a mobile access control system (1000) and method. The system (1000) comprises a mobile device (200), an access control device (300) and a credential management server (100). The mobile device (200) sends an access credential request message for the user to a credential management server (100), receives the credential data and a wireless communication range based on the user from the server (100), verifies the user based on a match between the credential data received from the server (100) and the credential data of the user stored in the mobile device (200), activates an access control application in the mobile device (200), and encrypts the received data. The access control device (300) establishes a connection with the mobile device (200) and receives the encrypted data from the mobile device (200) using the short-range wireless communication, decrypts the encrypted data, and controls the access to the secured area.
