Surveillance Video Playback User Permission Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing surveillance video playback methods require all users to view collected data associated with video data, lacking flexibility and resulting in an unsatisfactory user experience.
Innovation Solution
A method where a surveillance video playback system authenticates user permissions and only superimposes and plays collected data on video data for users with permission, using RTSP video playback link addresses to manage data access and playback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If collected data is superimposed on video data at the source during coding, then all users can view the collected data, but this reduces flexibility and forces users who do not need to see the data to view it
Solution Approach 1:
The system performs preliminary authentication of user permissions before video playback. The video surveillance management device authenticates whether the user has permission to view collected data in advance, and only then includes the collected data in the video stream. This prevents unnecessary data exposure to users who don't need it, while ensuring authorized users receive the complete information.
Solution Approach 2:
The system applies different data inclusion policies to different users based on their authentication results. Authorized users receive video streams with collected data superimposed, while unauthorized users receive video streams without the collected data. This localized differentiation resolves the contradiction by tailoring the information delivery to each user's specific needs and permissions.
2Loss of information
If collected data is always included in video playback, then data availability is maximized, but user experience deteriorates due to lack of control
Solution Approach 1:
The system performs preliminary authentication of user permissions before video playback. The video surveillance management device authenticates whether the user has permission to view collected data in advance, and only then includes the collected data in the video stream. This prevents unnecessary data exposure to users who don't need it, while ensuring authorized users receive the complete information.
Solution Approach 2:
The system uses authentication feedback to dynamically control data inclusion. Based on the user's permission status determined during authentication, the system feedback-adjusts whether to superimpose collected data on the video stream, optimizing data availability according to each user's authorized needs.
3Reliability
If permission authentication is implemented before video playback, then data security is improved, but system complexity increases
Solution Approach 1:
The video surveillance management device serves as an intermediary between the video source and the client device. It performs permission authentication and controls whether collected data is included in the video stream based on user authorization. This intermediary approach centralizes the authentication logic, improving data security while managing system complexity through a dedicated control component.
Data Source
AI summary
The surveillance video playback method includes receiving, by a video surveillance management device, a surveillance video browsing request from a client device, and performing, according to the request, authentication on a user that sends the surveillance video browsing request using the client device; if the user that sends the surveillance video browsing request has permission to view collected data, sending a first link address corresponding to the user request to the client device; and sending video data and the collected data to the client device according to a data request that carries the first link address and is returned by the client device, so that the client device can superimpose the collected data on the video data and then play them.
