Visual Code RTCS Transfer Across Unknown User Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication platforms cannot transfer real-time communication sessions (RTCS) between devices associated with different user accounts, limiting their functionality in scenarios where the identity of the receiving device or user is unknown.
Innovation Solution
Utilizing a visual code, such as a QR code, to authenticate and transfer RTCSs between devices with different user accounts by embedding device and session information, enabling seamless continuation of the session without prior knowledge of the recipient's identity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing communication platforms restrict RTCS transfer to devices within the same user account, then security and account management are simplified, but communication flexibility and usability are limited
Solution Approach 1:
The patent introduces a visual code (QR code) as an intermediary mechanism that enables RTCS transfer between devices of different user accounts. The code contains embedded authentication information that mediates the transfer process, allowing the system to maintain security while enabling flexible cross-account communication. The visual code acts as a trusted intermediary that bridges the gap between security constraints and communication flexibility.
2Ease of operation
If RTCS transfer requires prior knowledge of recipient identity, then security control is maintained, but usability in emergency and delivery scenarios is degraded
Solution Approach 1:
The system performs preliminary authentication by embedding device and session information within the visual code before the transfer occurs. This preliminary action of pre-packaging authentication data in the QR code allows the transfer to proceed seamlessly without requiring real-time identity verification or prior knowledge of the recipient, while still maintaining security controls through the embedded authentication mechanisms.
3Adaptability or versatility
If visual codes with embedded authentication information are used for RTCS transfer, then cross-account device transfer is enabled, but code generation and verification complexity increases
Solution Approach 1:
The patent uses a visual code (QR code) as a copyable and scannable representation of authentication information. Instead of complex direct device-to-device authentication protocols, the system creates a visual copy of the authentication data that can be easily generated, transmitted, and verified. This copying mechanism simplifies the user interaction while enabling cross-account transfer capability.
Data Source
AI summary
A conference system enables a communication session between two or more participants. During the communication session, a participant device displays a visual code that is scanned by the device in which the identity is unknown. Based on the scan of the visual code, the conference system transfers the communication session such that it is continued between the device in which the identity is unknown and the one or more devices of the remaining participants of the conference.
