Remote Controller Mediation for Password-Free Service Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face inconvenience when signing in or logging in to services on terminals like desktop computers or tablets, requiring password input, and there is a need to reduce the number of personal information inputs during user registration.
Innovation Solution
A remote control system comprising a mediation device, a terminal, and a remote controller, where the remote controller sends identification information to the mediation device to instruct the terminal to request a service from a server, allowing the terminal to receive the service without manual password input, and the mediation device confirms the terminal's identity before providing the service.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users input passwords manually on terminals to sign in or log in to services, then authentication reliability is ensured, but user convenience deteriorates and operation time increases
Solution Approach 1:
The invention introduces a remote controller as an intermediary device that stores authentication information and transmits it to the terminal. The remote controller acts as a mediator between the user and the service system, allowing users to access services without manually inputting passwords on the terminal while maintaining authentication security through the remote controller's verification mechanisms
Solution Approach 2:
The invention implements preliminary action by pre-storing authentication information in the remote controller before the service access moment. The terminal also performs preliminary actions by displaying confirmation screens and requiring user verification before accepting the transmitted authentication information, thus ensuring security before the actual service access occurs
2Reliability
If users are required to input multiple pieces of personal information during user registration, then service registration completeness is improved, but user convenience deteriorates and registration time increases
Solution Approach 1:
The invention extracts the personal information input process from the terminal registration flow and relocates it to the remote controller. The remote controller stores the user's personal information and uses it for authentication, eliminating the need for users to repeatedly input personal information during service registration on the terminal
Solution Approach 2:
The remote controller serves multiple functions: it stores personal information, performs authentication verification, and transmits authentication tokens. This multi-functional design eliminates the need for separate information input processes during different service registrations, reducing overall registration time while maintaining completeness
3Speed
If the terminal directly receives service requests without verification, then service access speed is improved, but system security deteriorates
Solution Approach 1:
The system performs preliminary verification actions before service access: the terminal displays confirmation screens with service information and requires user verification (such as pressing a button or entering a PIN) before the authentication token is transmitted. This preliminary action ensures security while maintaining fast access speed once verification is complete
Solution Approach 2:
The system implements feedback mechanisms where the terminal receives and verifies authentication tokens from the remote controller, confirms service details with the user through display, and only then proceeds with service access. This feedback loop ensures security verification while maintaining efficient service delivery

AI summary
In a remote control system (101), a terminal (121) waits for an instruction to be transmitted from a mediation device (111) by a browser, a virtual desktop, or the like. A remote controller (131) sends, to the mediation device (111), identification information that identifies the terminal (121) to be controlled and a service to be received by that terminal (121). If the terminal (121) identified by the sent identification information is waiting, the mediation device (111) transmits, to the waiting terminal (121), an instruction specifying the service identified by the sent identification information. The waiting terminal (121) sends, to a server (171) related to the service specified in the transmitted instruction, a request related to the service specified in the transmitted instruction. Note that it is possible to configure such that the server (171) provides the service after performing a confirmation that the terminal (121) that sends the request is the terminal (121) to be controlled.
