Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing security systems face challenges in ensuring temporary and dynamic access control while maintaining privacy, particularly in areas with video surveillance, where unauthorized access needs to be restricted without compromising confidentiality.
Innovation Solution
Implementing a computer-implemented method that applies time-limited video redaction to specific pixel areas and analyzes context information to dynamically adjust access permissions through physical access control systems, using security cameras and entry barriers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If video redaction is applied to maintain privacy, then privacy protection is improved, but access control monitoring capability deteriorates
Solution Approach 1:
The video redaction system dynamically adjusts its operation based on access control states. When unauthorized access is detected or suspected, the system automatically modifies redaction behavior to reveal relevant visual information to security personnel, while maintaining privacy protection during normal conditions. This dynamic adaptation resolves the contradiction by making the rediction capability flexible rather than fixed.
Solution Approach 2:
The system implements feedback loops where access control decisions influence video rediction behavior, and vice versa. Security personnel can override rediction when needed, and the system learns from these interactions to improve future access control decisions. This feedback mechanism ensures that privacy protection does not permanently compromise monitoring capability.
2Reliability
If access control permissions are made more restrictive, then security is improved, but ease of operation deteriorates
Solution Approach 1:
The system automatically analyzes video data and context information to make access control decisions without requiring constant manual intervention. AI algorithms automatically detect potential security threats and adjust access permissions accordingly, freeing security personnel from manually reviewing every access request while maintaining high security standards.
Solution Approach 2:
The system performs preliminary analysis of video data and context information before making access control decisions. By pre-processing and evaluating multiple data sources in advance, the system prepares access control decisions that can be executed quickly and automatically, reducing the operational burden on security personnel while maintaining restrictive security policies.
3Adaptability or versatility
If context information analysis is performed to dynamically adjust access permissions, then adaptability is improved, but device complexity deteriorates
Solution Approach 1:
The system uses a multi-functional processing platform that handles video analysis, context information processing, access control decision-making, and rediction management through integrated AI algorithms. This universal platform performs multiple functions through a single complex system rather than requiring separate specialized systems for each function, making the complexity more manageable.
Solution Approach 2:
The patent combines video analysis, context information processing, and access control decision-making into an integrated system. By merging these previously separate functions into a unified AI-driven platform, the system achieves high adaptability while consolidating complexity into a single manageable architecture rather than distributing it across multiple independent systems.
Data Source
AI summary
A physical security system and method for effecting a temporary access permission change are disclosed. The method includes analyzing context information, corresponding to a defined and applied, time-limited video redaction, to responsively define the temporary access permission change impacting a physical access control system of the physical security system. The method also includes effecting the temporary access permission change to at least make entry via an at least one entry barrier of the physical access control system more restricted than before the effecting of the temporary access permission change.
