Solution Overview

Problem

Deployed surveillance cameras are vulnerable to cyberattacks and video content interception, lacking security features and intelligence, which poses risks to confidentiality and privacy, and can have backdoors allowing unauthorized access.

Innovation Solution

An edge security apparatus is coupled to cameras, providing encryption, firewall technologies, and IoT functionalities, enabling secure content streaming, artificial intelligence processing, and unified management to protect cameras and video content from cyber threats without requiring camera replacement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If deployed cameras are made simple and cost-effective, then ease of manufacture and deployment is improved, but security vulnerability increases

Engineering Contradiction:

Improveease of manufactureVSAvoidsecurity vulnerability

Core Design Contradiction:

Ease of manufactureVSReliability

Solution Approach 1:

The patent introduces an edge security apparatus as an intermediary device that couples to the camera to provide security functions. This mediator handles encryption, firewall, and authentication tasks, allowing the camera itself to remain simple while gaining security capabilities through the attached security device.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If security features are added to deployed cameras, then security reliability is improved, but device complexity increases

Engineering Contradiction:

Improvesecurity reliabilityVSAvoiddevice complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent segments the camera system into two functional parts: the original camera device and an attached edge security apparatus. This segmentation allows security features to be added without modifying the camera's internal complexity, as the security functions are housed in a separate coupled device.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The edge security apparatus serves multiple functions including encryption, firewall protection, authentication, and video processing. By consolidating these diverse security and processing functions into a single universal device, the system avoids the complexity of adding multiple separate components to the camera.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Reliability

If encryption and security processing are performed, then video content security is improved, but processing time increases

Engineering Contradiction:

Improvevideo content securityVSAvoidprocessing time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The edge security apparatus performs preliminary actions by establishing security protocols and encryption keys before video transmission begins. This preliminary setup ensures that security is already in place when video content needs to be processed and transmitted, reducing real-time processing delays.

Inventive Principle:

Principle #10Preliminary action

AI summary

Example embodiments provide systems and methods for securing a deployed camera. A security apparatus is coupled to the deployed camera and accesses video content from the coupled camera. The security apparatus accesses video content from the coupled camera, splits the video content within a plurality of RTP packets, encrypts payloads of the RTP packets, embeds in a header of the encrypted RTP packets, at least two key identifications for decryption of the encrypted RTP packets, and transmits the plurality of RTP packets over a network to a video management system.
