Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing information management systems for events require participants to input personal information, such as names and departments, which prolongs the registration process and may deter participants from attending due to the perceived complexity or invasion of privacy.

Innovation Solution

An information management system that uses a digital key system, where a digital key is issued independently of personal information, and is used to create an ID image with a face image and a two-dimensional code. This system reduces the need for participants to input personal information and allows for the collection of behavior information without storing personal details.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If personal information input procedure is implemented for participant registration, then participant management precision is improved, but registration time is extended and participant willingness deteriorates

Engineering Contradiction:

Improveparticipant management precisionVSAvoidregistration time

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The patent extracts only the essential facial feature information from participants while leaving out detailed personal information collection. The face image is captured and stored as a unique identifier, eliminating the need for participants to input names, departments, and other personal details, thus reducing registration time while maintaining sufficient identification capability

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent uses facial images as copies or proxies for traditional personal information identifiers. Instead of collecting and storing actual personal data, the system creates a digital representation (face image) that serves as a unique identifier for each participant, enabling identification without invasive data collection

Inventive Principle:

Principle #26Copying

2Measurement precision

If personal information input procedure is implemented for participant registration, then participant identification precision is improved, but ease of operation deteriorates

Engineering Contradiction:

Improveparticipant identification precisionVSAvoidregistration ease

Core Design Contradiction:

Measurement precisionVSEase of operation

Solution Approach 1:

The system performs automatic face image capture and processing without requiring active participation from the registrant beyond presenting their face. The automated capture and processing of facial features eliminates manual information entry, making the registration process effortless while maintaining precise identification

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent replaces the mechanical process of manual information input and verification with an automated optical recognition system. The face image capture and processing system automatically identifies and registers participants, substituting human-operated data entry with automated image-based identification

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Measurement precision

If detailed personal information is collected, then participant management precision is improved, but information security risk increases

Engineering Contradiction:

Improveparticipant management precisionVSAvoidinformation security risk

Core Design Contradiction:

Measurement precisionVSObject-affected harmful factors

Solution Approach 1:

The patent extracts only the minimal necessary information (facial features) required for identification purposes, eliminating the collection of sensitive personal information such as names, contact details, and organizational affiliations. This reduction in data collection scope directly lowers information security risks while maintaining sufficient participant identification capability

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The system uses face images as temporary, purpose-specific identifiers that serve their function without requiring long-term storage or protection of sensitive personal data. The facial feature information is processed and stored in a manner that prioritizes identification functionality over creating permanent records of personal identity

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

AI summary

An information management system includes a reception device including a camera that images a face of a participant, and an information management apparatus. The information management apparatus issues a digital key assigned for each participant independently of personal information of the participant and transmits the digital key to the reception device. In a case where the reception device outputs an ID image of the participant, the information management apparatus acquires a face image from the reception device and stores the face image and the digital key in a database in association with each other. In a case where information including the digital key is received from a reading device installed in an event venue, the information management apparatus stores the received information in the database in association with the digital key as behavior information representing a behavior of the participant in the event venue.
