Localization-Based Intent Detection for Access Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional physical access control systems (PACS) face challenges in providing a seamless and efficient user experience due to delayed responses and the need for manual credential presentation, often resulting in frustration and potential unauthorized access from false intent detection.
Innovation Solution
A two-step authentication process using low-power communication (e.g., BLE) for initial credential transfer and ultra-wideband (UWB) for precise localization and intent detection, allowing credential caching until intent to access is confirmed, thereby reducing latency and improving security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional PACS uses manual credential presentation at entry points, then system simplicity is maintained, but user experience deteriorates due to delays and frustration
Solution Approach 1:
The system performs preliminary credential verification and intent detection before the user reaches the entry point. The reader detects the key device, verifies credentials, and determines user intent in advance, so that the door can be unlocked automatically when the user approaches, eliminating waiting time and manual presentation delays
Solution Approach 2:
The system enables automatic credential verification and access grant without requiring manual user actions. The key device automatically communicates with the reader, the system automatically verifies credentials and determines intent, and the door automatically unlocks, freeing the user from manual credential presentation
2Productivity
If PACS implements preemptive credential verification, then access speed is improved, but security deteriorates due to false intent detection
Solution Approach 1:
The system continuously tracks the key device location and monitors user approach behavior in real-time. By analyzing the trajectory and proximity data as feedback, the system can confirm whether the user is genuinely approaching the entry point or merely passing by, thereby reducing false intent detection while maintaining fast access speed
Solution Approach 2:
The system dynamically adjusts its intent detection criteria based on real-time location data and approach patterns. Rather than using static thresholds, the system adapts its verification requirements based on the user's movement dynamics, allowing for accurate intent detection that maintains both security and access speed
3Reliability
If PACS uses localization-based intent detection, then security is improved by reducing false positives, but system complexity increases
Solution Approach 1:
The system introduces a dedicated reader device as an intermediary between the key device and the door lock. The reader handles the complex tasks of detecting the key device, verifying credentials, tracking location, and determining intent, while the main PACS system remains relatively simple. This intermediary approach distributes complexity to a specialized component
4Reliability
If PACS requires manual credential presentation, then false access is prevented, but user convenience deteriorates
Solution Approach 1:
The key device automatically performs credential presentation by continuously broadcasting its identifier and communicating with the reader. The system automatically verifies the credential and determines intent without requiring the user to manually present the card or device, making the process convenient while maintaining security through automatic verification

AI summary
Systems and techniques for a physical access control systems with localization-based intent detection are described herein. In an example, an access control system may regulate access to an asset. The access control system is adapted to establish a first connection with a key-device. The access control system may be further adapted to receive a credential for a user over the first connection. The access control system may be further adapted to establish a second connection with the key-device. The access control system may be further adapted to determine an intent of the user to access the asset. The access control system may use location data derived from the second connection to determine the intent of the user. The access control system may be further adapted to provide the credential to an access controller, based on identifying an intent of the user to access the asset.
