Terminal Status-Based Password Transmission for Secure Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The accuracy of user and terminal authentication is inadequate because it cannot be determined whether a terminal is authenticated based on a password obtained from a user-selected terminal.
Innovation Solution
A method and system that acquire the status of multiple terminals connected via a network, select a terminal based on acquired statuses, and send a password to the selected terminal for authentication, improving authentication accuracy by determining the risk associated with each terminal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a user selects a terminal to receive a password, then the ease of operation is improved, but the reliability of authentication deteriorates because the terminal's security status cannot be verified
Solution Approach 1:
The terminal automatically transmits its status information to the information processing device without requiring user intervention. The terminal self-identifies its security status, communication capabilities, and input method characteristics, allowing the system to automatically select the most appropriate terminal while maintaining ease of operation.
Solution Approach 2:
The information processing device receives status feedback from multiple terminals and uses this information to determine the most suitable terminal for password transmission. The system continuously monitors terminal status including security state, communication availability, and input method status, then feeds this information back into the selection process to ensure reliable authentication.
2Reliability
If the system monitors the status of multiple terminals, then the reliability of authentication is improved, but the device complexity increases
Solution Approach 1:
The terminal status information is segmented into distinct categories: security status, communication status, and input method status. Each category is handled and evaluated separately by dedicated processing functions within the information processing device, making the complex monitoring task more manageable and systematic.
Solution Approach 2:
The information processing device performs multiple functions using a unified status acquisition mechanism. The same status monitoring infrastructure supports security verification, communication capability assessment, and input method determination, reducing overall system complexity while maintaining comprehensive terminal evaluation.

AI summary
A mechanism is provided for sending a password to a terminal. A password send request is received. The status of each of a plurality of terminals coupled to the information processing device via a network is acquired. On the basis of the acquired statuses, at least one item is selected from a group comprising the terminal serving as a destination for the password, the communication method with the terminal, or the method for inputting the password in the terminal. The password is then sent to the selected terminal via a network.
