Person Dangerousness Assessment via Historical Trajectory Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current security protection systems in smart parks struggle to effectively identify and prevent unscrupulous individuals from entering by relying solely on reactive measures, as they lack the ability to assess the potential danger of a person before they attempt to enter, making it difficult for security personnel to make timely judgments.
Innovation Solution
A method and system that generates a historical trajectory of a person's behavior using data from multiple devices, analyzes this data to determine suspicious behaviors, and assigns a suspicious level based on the frequency of these behaviors, determining the person as dangerous if the level exceeds a set threshold, incorporating face recognition and behavior analysis to identify and assess potential threats.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If reactive security measures are used to handle suspicious personnel at the gate, then security personnel can respond to immediate threats, but the system cannot assess potential danger before entry and cannot prevent infiltration by unscrupulous individuals
Solution Approach 1:
The system performs preliminary action by analyzing historical behavior data before the current security assessment is needed. It proactively evaluates potential threats by examining past trajectories and behaviors, enabling the system to assess danger before entry attempts occur, thus resolving the contradiction between reliable security assessment and timely response.
2Measurement precision
If traditional gate security inspection and video surveillance are used, then the system can detect suspicious behaviors at the entrance, but it cannot identify individuals who fabricate reasons for visit and infiltrate the park
Solution Approach 1:
The system performs preliminary action by analyzing historical behavior data before the current security assessment is needed. It proactively evaluates potential threats by examining past trajectories and behaviors, enabling the system to assess danger before entry attempts occur, thus resolving the contradiction between reliable security assessment and timely response.
3Productivity
If security personnel manually assess each person's danger level, then the system can make judgments about suspicious individuals, but it cannot efficiently handle large-scale personnel flow and real-time assessment requirements
Solution Approach 1:
The system performs self-service by automatically analyzing historical behavior data and generating danger assessments without requiring manual intervention from security personnel. The automated system processes large amounts of data independently, enabling efficient handling of large-scale personnel flow while reducing the complexity burden on human operators.
Solution Approach 2:
The system replaces the mechanical manual assessment process with an automated information processing system. By substituting human judgment with algorithmic analysis of historical data, the system achieves high-speed processing of personnel information while maintaining assessment accuracy, thus resolving the contradiction between productivity and system complexity.

AI summary
Disclosed are a method for determining the dangerousness of a person, an apparatus, a system and a storage medium. The method includes: generating a historical trajectory of a specific person according to historical data of the specific person acquired by a plurality of devices within a designated time period, where the historical data includes a person identifier of the specific person, an acquisition time and a device identifier; determining suspicious behaviors of the specific person appearing in the historical trajectory by means of analyzing behaviors of the specific person according to the historical trajectory of the specific person; determining a suspicious level of the specific person according to a frequency of at least one of the suspicious behaviors appearing in a corresponding historical trajectory; and determining that the specific person is dangerous in a case that the suspicious level exceeds a first set threshold.
