Secure Inter-Agency Communication via Video-Analytics Key Splitting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Inter-agency communication and resource sharing between different law enforcement agencies in an incident area are complicated, time-consuming, and costly due to the lack of convenient and secure methods for secure messaging and resource access.
Innovation Solution
A computer-implemented method using network-addressable devices and cameras to capture images, perform analytics, and generate and share encrypted key parts based on object attributes, allowing access to resources only with a complete key formed from decrypted key parts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional secure communication methods are used between different agencies, then security is maintained, but communication becomes complicated and time-consuming
Solution Approach 1:
The patent introduces a shared resource system with a centralized controller that acts as an intermediary between different law enforcement agencies. This mediator manages key distribution and resource access coordination, eliminating the need for direct complex inter-agency security protocols while maintaining security through controlled key sharing and authenticated access mechanisms.
2Reliability
If traditional secure communication methods are used between different agencies, then security is maintained, but communication becomes complicated
Solution Approach 1:
The patent creates a universal key management system that serves multiple agencies and purposes through a single standardized platform. The shared resource system provides multi-functional capabilities including key distribution, resource management, and access control across different agencies, replacing multiple agency-specific systems with one unified solution that reduces overall complexity.
3Reliability
If traditional secure communication methods are used between different agencies, then security is maintained, but costs increase
Solution Approach 1:
The patent merges separate agency communication and resource management systems into a single shared infrastructure. By combining key management, resource allocation, and inter-agency communication into one integrated system, the patent eliminates redundant security mechanisms and infrastructure costs while maintaining security through centralized control and shared authentication protocols.
4Ease of operation
If key parts are distributed to multiple agencies, then access control is improved, but key security risks increase
Solution Approach 1:
The patent segments the complete access key into multiple key parts and distributes them to different agencies. Each agency receives only a portion of the complete key, making it computationally infeasible for any single agency to reconstruct the full key without authorization. This segmentation enables decentralized access control while maintaining security through cryptographic threshold schemes.
Solution Approach 2:
The patent implements feedback mechanisms where the centralized controller monitors key part distribution and usage across agencies. The system tracks which agencies possess which key parts and controls reconstruction permissions dynamically, providing real-time feedback to prevent unauthorized key reconstruction and respond to security threats.

AI summary
Secure communication in a geographic incident area is disclosed. Computer-implemented methods are also disclosed, one of which is for restricting access to a resource and includes generating a key and splitting it into N key parts (where N is an integer greater than two). The method also includes encrypting the N key parts. The method also includes transmitting, over a network, to a device: the N encrypted key parts; and identifying information for N secret objects expected to be visible within the area. Each of the N encrypted key parts is decryptable based on at least one video analytics-discernable object attribute for each respective secret object of the N secret objects. The method also includes allowing an additional entity to access the resource only by presentation of a complete key formed from decrypted versions of less than all of the N key parts.
