Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Tailgating remains a common security issue in businesses despite various security measures, as existing solutions have limitations and cannot completely eliminate unauthorized access.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If security measures such as security cameras, turnstiles, security guards, and access control electronic devices are implemented, then security against tailgating is improved, but device complexity and cost increase
Solution Approach 1:
The patent combines video data from imaging devices with authentication data from access control systems into a unified analysis framework. By merging these existing separate data sources and analyzing them together through a single electronic device, the system achieves improved tailgating detection without adding separate dedicated hardware for each function, thus resolving the contradiction between security reliability and device complexity.
2Reliability
If multiple security measures are deployed to detect tailgating, then detection capability is improved, but loss of time for processing and analysis increases
Solution Approach 1:
The system continuously analyzes video data and authentication data in real-time as they are generated, rather than processing them in batches or after events occur. The electronic device continuously compares authentication events with corresponding video frames, enabling immediate detection of tailgating incidents without time delays, thus maintaining both high detection capability and minimal processing time.
3Reliability
If existing security measures are used, then some level of security is provided, but they cannot completely eliminate tailgating
Solution Approach 1:
The electronic device performs multiple functions using existing infrastructure: it analyzes video data for visual detection of tailgating, correlates authentication data from access control systems, and provides comprehensive security analysis. This multi-functional approach enables complete tailgating elimination using existing devices for their primary purposes, avoiding the need for additional specialized hardware while achieving comprehensive security coverage.
Data Source
AI summary
An electronic device and method for tailgating detection is provided. The electronic device receives data from an access control system for a physical entry point. When an event that indicates an access grant is detected, entry information for a period is collected. The information includes a set of authentications provided by the access control system. The electronic device receives a video from at least one imaging device, extracts object detection information from the video, and determines cost information based on a comparison of a time of each entry and a time of each authentication. Thereafter, the electronic device determines a correspondence between a subset of the entries and the authentications based on the cost information. The electronic device detects, from entries included in the object detection information, one or more entries that are different from the subset as tailgating entries. An output device renders tailgating information based on such entries.
