Biometric Warning Device for Allergen Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems fail to provide users with allergy information associated with products they intend to purchase, as they do not collate product substances with user allergy information.
Innovation Solution
A warning device and system that acquires biometric information, performs personal authentication, retrieves user attribute information, matches it with product substance information, and outputs warnings if the substance corresponds to known allergies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If biometric authentication and product substance analysis are integrated to provide allergy warnings, then user safety is enhanced, but device complexity increases
Solution Approach 1:
The system is divided into distinct functional modules: biometric information acquisition unit, authentication request unit, attribute information acquisition unit, substance information acquisition unit, determination unit, and output unit. Each module handles a specific task in the allergy warning process, making the complex system manageable and maintainable while ensuring user safety through comprehensive verification
Solution Approach 2:
The warning device acts as an intermediary between the user (via imaging device), authentication device, product information sources, and display terminal. It coordinates multiple data sources and processes to generate allergy warnings, resolving the complexity by centralizing the integration logic in a dedicated intermediary system rather than requiring direct connections between all components
2Measurement precision
If multiple data acquisition steps are performed for authentication and product analysis, then warning accuracy is improved, but processing time increases
Solution Approach 1:
Biometric information is acquired and authenticated before the user selects or purchases the product. The authentication device pre-verify the user's identity and retrieve their allergy attribute information in advance, so that when the user selects a product, the substance information can be quickly compared against already-retrieved allergy data, reducing overall processing time while maintaining high warning accuracy

AI summary
A warning device (100) includes: a biometric information acquisition unit (112) that acquires biometric information included in a captured image captured by a predetermined imaging device; an authentication request unit (114) that causes an authentication device (200) that stores biometric information of a plurality of users to perform personal authentication for the acquired biometric information; an attribute information acquisition unit (115) that acquires attribute information of a user who has succeeded in the personal authentication in a case where the personal authentication has succeeded; a substance information acquisition unit (116) that acquires substance information included in a product selected by the user; a determination unit (117) that determines whether or not the substance information corresponds to the attribute information; and an output unit (118) that outputs warning information to a predetermined display terminal in a case where the substance information corresponds to the attribute information.
