Lost Item Identification via Encrypted Emblem Symbols
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In childcare institutions, existing systems that use barcodes or two-dimensional codes to identify lost items risk leaking personal information, as decoders can be easily obtained by unauthorized individuals, necessitating a method to specify the owner without revealing personal information.
Innovation Solution
An information processing device and method that acquires and analyzes image data from a symbol attached to lost items, using a unique emblem to identify the owner without being known by third parties, employing a system with an information terminal and management server for secure data communication and image recognition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If barcodes or two-dimensional codes are used to identify lost items, then the owner can be specified at a glance, but personal information is leaked because decoders can be easily obtained by unauthorized individuals
Solution Approach 1:
The patent introduces an intermediary system consisting of a management server and encrypted emblem data. Instead of using directly readable barcodes, the system uses encrypted emblem images that require authentication through the management server to decode, thus mediating between the lost item identification need and the privacy protection requirement
Solution Approach 2:
The patent changes the parameter of data encoding from plain text or standard barcodes to encrypted emblem images. The emblem data is transformed through encryption algorithms before storage and transmission, changing its form from directly readable to requiring authorized decryption, thereby preventing unauthorized access while maintaining identification functionality
2Ease of operation
If names are directly written on belongings, then the owner can be specified at a glance, but personal information leakage is concerned
Solution Approach 1:
The patent uses visual emblems as copies or representations of owner identification rather than direct name writing. The emblem serves as a visual surrogate that conveys ownership information to authorized users while appearing as decorative or abstract imagery to unauthorized users, thus separating the identification function from the direct exposure of personal information

AI summary
According to one embodiment, an information processing device includes acquisition means, detection means, and specifying means. The acquisition means acquires image data according to a lost article to which a symbol of a user is attached and identification information according to a group to which the user belongs. The detection means performs analysis set for each item of identification information according to the group with respect to the image data according to the lost article and detects the identification information for identifying the user included in the symbol. The specifying means specifies the user from the identification information detected by the detection means.
