Presence Verification via Guided Device Actions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing personal verification methods, such as those combining camera and microphone data, do not effectively verify a user's presence in a specific location, leading to inaccuracies in determining where the user is present.
Innovation Solution
A verification method and system that designates and uses one or more devices in a location to guide the user through specific actions, collates the executed actions with pre-defined action information, and outputs a result to confirm the user's presence, ensuring accurate verification by preventing impractical device designation and reducing false positives through action frequency and sequence analysis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multi-factor verification combining camera and microphone is used, then personal verification accuracy is improved, but the ability to verify user presence in a specific location deteriorates
Solution Approach 1:
The patent combines multiple verification factors including device location data, user actions, and device metadata into a unified presence verification system. This merging of verification methods allows the system to simultaneously achieve personal verification accuracy and location verification reliability by requiring both identity confirmation and location validation through the same device interaction sequence.
2Adaptability or versatility
If any device in a location is designated for verification, then verification flexibility is improved, but false positives increase due to impractical device designation
Solution Approach 1:
The system performs preliminary filtering of devices based on executable action criteria before designating verification devices. By pre-establishing which devices can perform required actions (such as camera capture, sensor reading, or display output), the system maintains flexibility in device selection while preventing false positives from devices incapable of performing verification actions.
Solution Approach 2:
The system incorporates feedback mechanisms that analyze the results of verification actions to determine device suitability. By monitoring whether designated devices can successfully execute required actions and producing verification results, the system adjusts future device designations to avoid impractical choices, thereby reducing false positives while maintaining verification flexibility.
3Ease of operation
If simple device presence check is used, then verification simplicity is improved, but accuracy of determining user presence deteriorates
Solution Approach 1:
The system employs a multi-step verification process that requires users to perform multiple actions (such as capturing images, reading displays, or interacting with sensors) rather than a single simple check. This excessive action approach maintains operational simplicity from the user perspective while significantly improving presence detection accuracy by requiring multiple independent verification events that must all succeed.

AI summary
A verification method by a computer includes: accepting information that requires verification of presence of a user in a certain place; designating one or more first devices in the certain place as a verification-use device; notifying verification action information indicating execution guidance for a verification action to the verification-use device; collating information indicative of an action having been executed to the verification-use device after the notification of the verification action information with the verification action information; and outputting information indicative of a result of the collation.
