Portable Device Authentication via Action Feedback Signals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information processing systems fail to accurately determine whether a user is holding the correct portable device associated with them, leading to incorrect health status management and operational process reforms, especially when malicious users wear incorrect wearable terminal devices.
Innovation Solution
An information processing apparatus with an authenticating unit, transmitting unit, detecting unit, and determining unit is employed, which transmits action instructing signals to the wearable terminal device via a radio communication line, detects changes in the device's status, and determines if the user is correctly holding the device by matching the instructed actions, using unpredictable light-emission patterns, visual changes, or bio-information continuity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the system only uses traditional authentication methods (e.g., password, fingerprint), then the authentication process is simple and fast, but the system cannot determine whether the user is holding the correct portable device associated with them
Solution Approach 1:
The system transmits action instructing signals to the portable device and detects changes in its status, using the device's response as feedback to determine whether it is the correct device. This feedback mechanism enables accurate device identification without requiring complex additional hardware.
Solution Approach 2:
The authentication system integrates multiple functions into a single process: it authenticates the user, transmits instructions to the portable device, detects status changes, and determines device ownership. This multi-functionality approach increases measurement precision without proportionally increasing device complexity.
2Reliability
If the system accepts any portable device during authentication, then the authentication process is fast and simple, but incorrect sensor information may be recorded and health status management becomes inaccurate
Solution Approach 1:
The system performs preliminary authentication and device verification before allowing the user to use the service. By determining whether the user is holding the correct portable device as part of the authentication process, the system prevents incorrect sensor information from being recorded without significantly delaying the overall process.
Solution Approach 2:
The system uses feedback from the portable device's status changes to verify device ownership. This feedback mechanism ensures that only correct sensor information from the associated device is recorded, improving reliability while maintaining efficient authentication timing.
3Measurement precision
If the system uses complex verification methods to ensure correct device holding, then device identification accuracy improves, but the authentication process becomes more time-consuming
Solution Approach 1:
The system uses periodic action instructing signals transmitted to the portable device, which responds with status changes. This periodic interaction pattern allows the system to verify device possession through multiple simple checks rather than one complex verification, improving accuracy without significantly increasing total authentication time.

AI summary
An information processing apparatus includes an authenticating unit, a transmitting unit, a detecting unit, and a determining unit. The authenticating unit authenticates a user who is holding a portable device. The transmitting unit transmits an action instructing signal for issuing an instruction to perform an action to a portable device that is associated with the user, via a radio communication line. The detecting unit detects a change of a status of the portable device that is being held by the user. The determining unit determines, by determining whether or not the change corresponds to the instructed action, whether or not the user is holding the portable device.
