Remote Device Authorization via Intermediary Login Codes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for remote authorization on devices without display screens or input capabilities are inefficient and limited, as they often require direct user interaction with verification codes and URLs, making it difficult to manage multiple devices simultaneously.
Innovation Solution
A remote authorization method that identifies target devices connected to a network, transmits a remote login request to an account server, receives a login code and method, requests a terminal verification code, and uses a login key to remotely log in or log out devices, enabling multiple devices to be managed simultaneously.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If direct user interaction with verification codes and URLs is required for remote authorization, then security is improved, but ease of operation deteriorates for devices without display screens or input capabilities
Solution Approach 1:
The patent introduces an intermediary device (such as a smartphone or computer) that acts as a mediator between the user and the target device without display/input capabilities. The intermediary device receives the verification code and URL, displays them to the user, and automatically transmits the verification code back to complete authorization, eliminating the need for direct user interaction with the target device's interface.
Solution Approach 2:
The system enables self-service authorization by allowing the intermediary device to automatically handle the verification code transmission without requiring manual input from the user. The device itself performs the authorization action based on pre-established trust relationships, making the process autonomous and eliminating the need for display or input capabilities on the target device.
2Reliability
If traditional authorization methods are used for each device individually, then authorization security is maintained, but productivity deteriorates when managing multiple devices
Solution Approach 1:
The patent merges multiple device authorizations into a single unified process. Once the user authorizes one device through the intermediary, the system automatically extends authorization to other devices in the group, allowing simultaneous login across multiple devices without repeating the verification process for each individual device.
Solution Approach 2:
The authorization mechanism becomes universal by creating a group authorization model where a single verification action grants access across multiple devices. The system treats a group of devices as a single authorization unit, allowing the user to manage multiple devices simultaneously through one unified authorization interface on the intermediary device.
3Ease of operation
If verification codes are exposed to users on target devices without display screens, then ease of operation improves, but device complexity increases
Solution Approach 1:
The intermediary device serves as an external display and input interface for the target device. It receives the verification code and URL from the target device, presents them to the user through its own display capabilities, and captures the user's verification input, thereby eliminating the need for the target device to have display or input hardware.

AI summary
A remote authorization method and an electronic device for performing the method are provided. The remote authorization method includes the steps of identifying information of a target device connected to a network, transmitting a request for remote login to the target device to an account server, in response to the remote login request, receiving, from the account server, a remote login code for identifying the remote login request and a remote login method determined according to the information of the target device, requesting a terminal authorization code from the target device by using the remote login code, receiving an input of the terminal authorization code, which is output by the target device according to the remote login method, from a user, transmitting the terminal authorization code to the account server, and receiving a login key for remote login of the target device from the account server, and transmitting the login key to the target device.
