Secure Video Stream Sharing for Emergency Response
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video surveillance systems do not provide secure and efficient access to private surveillance networks for emergency responders during critical situations, limiting their ability to respond effectively to emergencies.
Innovation Solution
A system that allows facility administrators to securely share selected video streams with pre-designated public service agencies by activating access through authentication and permissions, enabling real-time video access on mobile devices during emergencies while maintaining privacy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If private surveillance networks are made accessible to public service agencies, then emergency response capability is improved, but security and privacy are compromised
Solution Approach 1:
The surveillance system segments access rights by creating distinct user roles (facility administrators, authorized personnel, public service agencies) with different permission levels. The system divides camera access into shared and unshared streams, allowing selective disclosure of surveillance data only when and to whom needed, thus enabling emergency response while maintaining security through controlled information segmentation.
Solution Approach 2:
The system implements dynamic access control where permission settings can be changed in real-time based on emergency conditions. Facility administrators can activate or deactivate shared camera streams dynamically, and the system automatically adjusts access rights for public service agencies based on current emergency status, allowing the system to adapt between secure private operation and emergency shared access.
2Loss of information
If real-time video access is provided to first responders, then situational awareness is improved, but system complexity increases
Solution Approach 1:
The system uses a universal authentication and permission framework that serves multiple functions: it authenticates different user types (facility administrators, authorized personnel, public service agencies), manages various permission levels (shared/unshared cameras, live/historical streams), and provides both mobile and web access interfaces. This multi-functional approach reduces overall system complexity by consolidating management functions.
Solution Approach 2:
The system introduces a cloud-based video streaming server as an intermediary between the surveillance cameras and first responders. This intermediary handles all complex tasks including authentication, permission verification, video stream routing, and protocol translation, shielding users from system complexity while providing seamless real-time video access to authorized users.
3Productivity
If camera access is shared with public service agencies, then emergency response effectiveness is improved, but privacy protection is reduced
Solution Approach 1:
The system applies local quality by providing different levels of access to different users and different camera streams. Public service agencies receive access only to specific shared cameras and historical streams relevant to emergencies, while facility administrators maintain full access to all cameras. The system can selectively share only necessary video streams and metadata, preserving privacy by limiting disclosure scope to what is locally needed for emergency response.
Data Source
AI summary
A video surveillance service shares image streams with public service agencies in the event of emergency. Nominated agencies establish access credentials at the surveillance service data center. A video stream is shared by a customer administrator's selection of permissions on each camera via privileged web-browser. Permissions enable selection by static meta data such as type, audio, location, motion, and epoch. Video streams of present and past epochs are controlled by time. A public service agency receives an electronic notification from the administrator to present their access credential and a handle for each shared camera of interest. A notification is customized for each public service agency and each event by dynamically generating a link to a secure webserver which records geo-location or network identifiers for validation. Video servers may include virtual machines dedicated to each public service agency but controlled by a customer administrator.
