Emergency Video Access via UDP Authentication and QR Codes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional video surveillance systems require authorized accounts and passwords for emergency services to access private security camera streams, which is impractical and compromises access control for facility owners.
Innovation Solution
A system that authenticates UDP packets with an access control server and initiates an API at a video server, allowing emergency services to access private video streams without creating new accounts or IDs, using a fictitious Domain Name System (DNS) and QR-like codes for secure, time-controlled access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If authorized accounts and passwords are required for emergency services to access private security camera streams, then access control security is maintained, but emergency access speed and ease of operation deteriorate
Solution Approach 1:
The system pre-configures access control settings and authentication mechanisms before emergencies occur. Facility owners pre-register emergency services agencies and define access policies in advance, so that during emergencies, authentication occurs automatically without requiring real-time account creation or password entry, thus maintaining security while enabling rapid access
Solution Approach 2:
The patent introduces an access control server as an intermediary between emergency services and video surveillance systems. This server handles authentication and authorization automatically using pre-configured policies, eliminating the need for manual account management while maintaining security controls. The intermediary processes access requests based on predefined rules, enabling fast emergency access without compromising security
2Adaptability or versatility
If new user accounts and IDs are created for emergency services access, then access control granularity is improved, but system complexity and administrative burden increase
Solution Approach 1:
The system uses universal authentication mechanisms that work across multiple facilities and emergency services agencies without requiring separate account systems. The access control server implements a unified policy framework that can be applied universally, allowing granular control through configuration rather than through complex account management, thus reducing system complexity while maintaining adaptability
Solution Approach 2:
The patent implements dynamic access control where authentication parameters (such as time of day, facility type, emergency level) are changed based on conditions rather than requiring separate accounts for each scenario. This allows the system to provide granular access control for different situations by modifying parameters in existing authentication mechanisms, avoiding the complexity of creating numerous user accounts
3Reliability
If cloud-based video surveillance with security systems is used, then video security and reliability are improved, but access control flexibility for emergency services deteriorates
Solution Approach 1:
The system implements dynamic access control policies that can be adjusted in real-time based on emergency conditions. The access control server can modify authentication requirements, access permissions, and session durations dynamically during emergencies, providing flexibility to cloud-based systems without compromising their inherent security. This allows the system to adapt to different emergency scenarios while maintaining cloud-based security architecture
Data Source
AI summary
Private video streams are provided to emergency services agents' devices by authenticating UDP packets at an access control server and initiating an Application Programming Interface at a video server. The access control server conditionally responds to a UDP query from a mobile device with an answer containing an address of an API. Settings provided by a facility/video stream owner validate the query, and synthesize a one-time IPv6 address. A virtual machine image of an API couples cameras to mobile devices. Video images are transformed into a pastiche with 2D facility maps or 3D models. The device transforms an optical image e.g. a QRcode into a packet for transmission as a query. The packet contains authentication credentials and identity indicia of sender and desired video image access. The device receives a reply containing the address of the API and displays resulting video.
