QR Code Video Conference Access via Server Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video conferencing technologies lack a seamless method for new participants to join ongoing conferences, especially in a remote and distributed environment, where easy and secure access is required.
Innovation Solution
A method utilizing a QR code to allow users to participate in video conferences by generating identification information, including a URI or URL with a hash value, which is transmitted through a server connected to participant terminals, enabling secure and convenient access using a camera-equipped terminal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional video conferencing methods are used, then existing participants can maintain conference sessions, but new participants cannot easily join ongoing conferences
Solution Approach 1:
The system generates a QR code containing conference identification information in advance, which can be displayed to new participants before they join. This preliminary preparation eliminates the need for complex real-time joining procedures, allowing new participants to quickly scan and enter the conference.
Solution Approach 2:
A QR code serves as an intermediary carrier that transmits conference identification information between the conference system and new participants. Instead of direct complex authentication, the QR code mediates the joining process by encoding necessary conference data that can be easily scanned and processed.
2Ease of operation
If QR code with identification information is used, then new participants can easily join conferences, but security concerns arise from unauthorized access
Solution Approach 1:
The QR code contains localized identification information specific to each conference session, including unique identifiers and authentication tokens. This localized encoding ensures that each QR code is valid only for its specific conference, preventing unauthorized access to other conferences while maintaining easy joining for legitimate participants.
Solution Approach 2:
The system changes the parameter of identification information by encoding it within the QR code structure. The identification information includes dynamic parameters such as conference IDs, authentication tokens, and timestamp data, which transform the static QR code into a secure, time-limited access key that validates participant authorization.
3Reliability
If complex authentication methods are used, then conference security is improved, but ease of joining conference deteriorates
Solution Approach 1:
The system replaces complex mechanical authentication procedures (manual password entry, multi-step verification) with an optical scanning mechanism. The QR code encapsulates all authentication data, and scanning it automatically triggers the joining process, substituting time-consuming manual operations with a quick camera-based recognition system that maintains security while dramatically reducing joining time.

AI summary
Provided is a method of allowing a user to participate in a video conference using a quick response (QR) code, which is a method performed by a server connected to a plurality of participant terminals and a user terminal via a wired/wireless network, the method including: generating a conference session with the plurality of participant terminals to initiate the video conference; generating identification information for identifying the video conference so that the user terminal is allowed to access the video conference; transmitting the identification information to a participant intermediary terminal that is one of the plurality of participant terminals; and upon recognizing, by the user terminal, a QR code output on the participant intermediary terminal, allowing the user terminal to participate in the video conference.
