Video Check-In Authentication via Multimedia Data Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video-based check-in methods lack authenticity as users can perform check-ins without actually watching the video, leading to unreliable user responses.
Innovation Solution
A method where a terminal collects multimedia data and time information from a currently played video, sends it to a server, and receives a check-in manner only if the user is determined to be watching the video, ensuring check-in is based on actual video watching.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the terminal allows check-in anytime and anywhere without verifying video watching, then the ease of operation is improved, but the authenticity of check-in data deteriorates
Solution Approach 1:
The system performs preliminary verification by collecting multimedia data and time information before allowing check-in. The terminal captures video content and timing data in advance, then transmits it to the server for verification before enabling the check-in process, ensuring users actually watched the video.
Solution Approach 2:
The server provides feedback by receiving multimedia data and time information from the terminal, verifying whether the user actually watched the video, and only then allowing check-in to be completed. This feedback mechanism ensures authenticity while maintaining user-friendly operation.
2Reliability
If the system verifies video watching through multimedia data collection, then the authenticity of check-in data is improved, but the device complexity increases
Solution Approach 1:
The server acts as an intermediary that receives multimedia data and time information from the terminal, performs verification, and controls whether check-in is allowed. This intermediary approach distributes complexity between client and server, keeping the terminal design relatively simple while enabling authentic verification.
3Reliability
If the terminal collects multimedia data and time information before check-in, then the reliability of user response is improved, but the loss of time increases
Solution Approach 1:
The system performs data collection and verification in advance before the check-in action is allowed. By capturing multimedia data and time information beforehand and verifying it through the server, the system ensures reliable user responses while the time loss is minimized through efficient processing.

AI summary
A video-based check-in method, terminal, and server are provided. The method includes: obtaining a check-in instruction; collecting multimedia data corresponding to a currently played video; determining time information corresponding to the multimedia data; sending the multimedia data and the time information to a server; receiving a check-in manner sent after the server determines according to the multimedia data and the time information that a user is watching the video; and displaying the check-in manner, and completing check-in on the video according to the check-in manner.
