Surveillance Video Privacy Protection via Identity Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing surveillance video systems lack effective privacy protection, allowing unauthorized users to freely view surveillance videos stored on network routers, posing a risk to user privacy.
Innovation Solution
A method and apparatus that perform identity authentication on users requesting to view surveillance videos, with optional privacy protection operations such as hiding or encrypting the files, and secure key distribution using RSA public-key cryptosystems to ensure only authorized users can access the content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If surveillance video is stored on network router for convenient viewing and backup, then ease of operation is improved, but privacy protection deteriorates as any user can freely view the video
Solution Approach 1:
The patent introduces an intermediary authentication mechanism between users and surveillance video files. The system acts as a mediator that verifies user identities and controls access permissions, preventing direct unauthorized access while maintaining convenient viewing for authorized users. This resolves the contradiction by adding a security layer without sacrificing ease of operation for legitimate users.
Solution Approach 2:
The patent applies different access permissions and authentication requirements to different users based on their authorization levels. Instead of uniform access control, the system tailors security measures to specific users and their needs, allowing convenient access for authorized users while blocking unauthorized access. This localized approach to security resolves the contradiction between ease of operation and privacy protection.
2Object-affected harmful factors
If identity authentication and encryption are implemented for surveillance video access, then privacy protection is improved, but device complexity increases
Solution Approach 1:
The patent implements automatic authentication and encryption mechanisms that operate without requiring complex user configuration. The system autonomously manages security protocols, user verification, and file protection, reducing the operational complexity burden on users while maintaining strong privacy protection. This self-service approach resolves the contradiction by automating security functions.
Solution Approach 2:
The patent performs authentication and encryption operations in advance before video access is requested. User identities are verified and files are encrypted beforehand, so that when access is needed, the security measures are already in place. This preliminary action reduces the perceived complexity during actual video viewing operations while maintaining strong security.
3Reliability
If file encryption is applied to surveillance video, then reliability of privacy protection is improved, but ease of operation deteriorates due to key management requirements
Solution Approach 1:
The patent introduces an intermediary key management system that handles encryption key distribution and management automatically. Instead of requiring users to manually manage complex encryption keys, the system acts as a mediator that securely distributes keys to authorized users and manages their lifecycle. This resolves the contradiction by maintaining strong encryption reliability while eliminating key management complexity for users.

AI summary
The present disclosure relates to a method and an apparatus for processing a surveillance video. The method includes: acquiring from a user account a view request for viewing a surveillance video file, the view request including authorization information of the user account; performing an identity authentication on the user account according to the authorization information; and allowing the user account to view the surveillance video file when the identity authentication is passed. The present disclosure is used to prohibit freely viewing the surveillance video file.
