Wireless Access Control Using Mobile Identifier Pre-Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing access control systems face challenges in efficiently differentiating authorized users from unauthorized ones, particularly in high-traffic environments like office buildings, leading to congestion and delays.
Innovation Solution
A radio communication-based access control system that uses a transmitting and receiving device to identify and authenticate users through their mobile electronic devices, storing user identifiers and passwords in a database for quick verification, and allowing access only to authorized users, with optional secure encryption and additional authentication methods like optical codes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional access control systems check all users in high-traffic areas, then security verification is thorough, but processing time increases and congestion occurs
Solution Approach 1:
The system performs preliminary authentication by receiving and storing user identifiers from mobile devices in a public area before users reach the restricted area. This advance verification allows the system to quickly match users against the authorized list when they arrive at the access point, eliminating the need for slow sequential checking at the entrance and reducing congestion in high-traffic situations.
Solution Approach 2:
The access control process is divided into two separate stages: (1) identifier reception and storage in the public area, and (2) password verification at the restricted area entrance. This segmentation allows authentication to begin before users reach the access point, enabling parallel processing and significantly reducing the time users wait at the entrance while maintaining thorough security verification.
2Reliability
If access control systems use multiple authentication methods, then security is improved, but system complexity increases
Solution Approach 1:
The system uses a mobile device that serves multiple functions: it stores the user identifier, generates the password, and communicates with the access control system. This multi-functional approach allows the system to implement two-factor authentication (something the user has - the mobile device, and something the user knows - the password) without requiring separate physical authentication devices, thereby maintaining high security while avoiding increased system complexity.

Function Achieved in This Case
This system ensures fast and secure access control, reducing congestion by verifying only the passwords of present users, allowing authorized individuals to enter restricted areas quickly and securely, even in high-traffic situations.

AI summary
The invention relates to an access control system (1) comprising a transmitter and receiver unit (14) for radio communication with a mobile electronic device (6) of a user (2), which is configured for receiving an identifier (Ki) of the mobile electronic device (6) when the mobile electronic device (6) is in a public area (10) from which the user (2) can request access to an access-restricted area (8). A storage unit (26, 28) is configured for creating a dataset (DSi) for the identifier (Ki), which is assigned to the user (2) present in the public area (10), and for storing a password (Ci) in the first dataset (DSi) so that the password (Ci) is assigned to the identifier (Ki). A code processing unit (16, 22) is configured in order to recognise a password (Cd) presented by the user (2), when the user (2) requests access to the access-restricted area (8). A processor unit (20) is configured for determining whether the identifier (Ki) in a database (34) is assigned to a user profile; if it is, authenticating the user (2) as being authorised for access; and determining whether the recognised password (Cd) corresponds with the password (Ci) stored in the dataset (DSi), wherein the user (2) is recognised as a user (2) requesting access if they correspond.
