Image Scanning Virtual Desktop Session Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In virtual desktop environments, users face inconvenience due to the need to repeatedly log in and out of devices, often losing session state and unsaved data, as they switch between devices, and there is a lack of efficient methods to authenticate and transfer virtual desktop sessions.
Innovation Solution
The use of image scanning and encoding technologies, such as QR codes, to authenticate devices and transfer virtual desktop sessions between devices, allowing seamless migration of sessions without the need for repeated login credentials by encoding and decoding information securely.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users manually enter username and password for each device login, then authentication security is maintained, but user convenience and access efficiency deteriorate
Solution Approach 1:
The system performs preliminary authentication by capturing device information (IMEI, MAC address, device fingerprint) when the user first logs in. This authentication data is stored and reused for subsequent logins on the same or different devices, eliminating the need for repeated manual credential entry and significantly reducing login time while maintaining security
Solution Approach 2:
The system creates a digital copy of the user's authentication state and session information. When a user logs in from one device, the system generates authentication tokens and session data that can be transferred to other devices, allowing the user to access their virtual desktop without re-entering credentials on each new device
2Reliability
If users log out from one device to access from another, then device security is maintained, but session state and data are lost
Solution Approach 1:
The authentication system is designed to be universal across multiple devices. Instead of tying session state to a single device, the system creates device-agnostic authentication tokens that work across any device in the user's registered device list, allowing seamless transitions between devices while preserving session state
Solution Approach 2:
The system introduces an intermediary authentication service that acts as a mediator between the user's virtual desktop and multiple client devices. This intermediary stores session state independently of any specific device and manages token-based authentication, allowing users to switch devices without losing their session information
3Productivity
If image scanning is used for authentication, then user convenience is improved, but authentication security requirements become more complex
Solution Approach 1:
The system replaces manual mechanical input (typing username and password) with optical scanning (QR code or image capture). The authentication mechanism uses the device's camera to scan visual codes, converting a complex multi-step manual authentication process into a simple single-action scan that dramatically improves access efficiency while the underlying security mechanisms remain managed by the system

AI summary
Image scanning and encoding technologies can be utilized to authenticate devices to virtual desktops and to transfer virtual desktop sessions between devices. One device (e.g., PC or laptop) may encode certain information into an image that is displayed on a display screen, while another mobile device equipped with a digital camera (e.g., mobile phone or tablet) can be used to scan the image on the display screen. Once the image is scanned, it can be decoded by the mobile device to get the information encoded in the image (e.g., device ID, session ID, etc.). The information obtained from the image can be used to authenticate a device or to transfer a virtual desktop session between the devices.
