Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing methods for authenticating and validating the identity of objects, such as vehicles, parcels, and luggage, are inefficient, lack security, and cannot reliably detect tampering or misassignment of tags, particularly in dynamic environments.

Innovation Solution

A method utilizing multiple data memories assigned to tags on an object, where each tag has a unique data structure, allowing for contactless reading and authentication through a reading device that uses a selector value to efficiently identify and validate the object's identity by comparing data elements across tags, ensuring authenticity and validity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual visual inspection with self-adhesive security labels is used, then authentication capability is provided, but time consumption and efficiency are poor

Engineering Contradiction:
Improveauthentication capabilityVSAvoidtime consumption
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent replaces manual visual inspection with automated optical character recognition (OCR) systems that use cameras and image processing algorithms to automatically read and verify license plate characters, eliminating the need for manual comparison of security labels while maintaining authentication reliability

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent creates digital copies of license plate information through imaging systems and stores them in databases for automated comparison and verification, enabling rapid authentication without manual intervention by creating and processing digital representations of the physical license plates

Inventive Principle:
Principle #26Copying

2Reliability

If license plates are permanently fitted to vehicles, then identification capability is improved, but theft protection and anti-counterfeiting are insufficient

Engineering Contradiction:
Improveidentification capabilityVSAvoidtheft and counterfeiting
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent segments the authentication system into multiple independent components: physical license plates on vehicles, portable authentication devices carried by officials, and centralized databases, where each component performs a specific function and together they provide comprehensive security against theft and counterfeiting

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces portable authentication devices as intermediaries between the license plates and the verification process, these devices contain authentication algorithms and can independently verify license plate validity by comparing against stored data, adding a security layer that prevents unauthorized use even if plates are removed or altered

Inventive Principle:
Principle #24Intermediary (Mediator)

3Productivity

If optical character recognition is used for automatic identification, then reading speed is improved, but authentication reliability and anti-counterfeiting are insufficient

Engineering Contradiction:
Improvereading speedVSAvoidauthentication reliability
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The patent merges optical character recognition technology with portable authentication devices that contain verification capabilities, combining the speed of automated optical reading with the reliability of algorithmic authentication to achieve both high productivity and high reliability simultaneously

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent implements feedback mechanisms where the portable authentication device immediately verifies license plate information against stored data and provides real-time verification results, allowing officials to instantly determine authenticity while maintaining high reading speeds through automated processing

Inventive Principle:
Principle #23Feedback

4Reliability

If multiple data memories are used for authentication, then security and reliability are improved, but device complexity increases

Engineering Contradiction:
Improveauthentication securityVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent designs portable authentication devices with multi-functional capabilities that can read multiple data memories, perform authentication algorithms, store reference data, and communicate with databases, consolidating what would otherwise require multiple separate systems into a single universal device

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

A method for authenticating and/or validating an identity of an object and information about the object, wherein the identity and the information relating to the object are stored in at least two, preferably three, four or more, data memories of a respective tag and these data memories are read out contactlessly by a reading device. The tags can be read out in arbitrary permutations on the object. Data sets with a plurality of data elements are stored in the data memories in a specified order, wherein the data elements comprise the identity or information relating to the object, the tag and/or a multiplicity of directly accessible authentication codes. Each data element is assigned to a permutation of the tags, thus providing a single directly accessible authentication code for authentication and/or validation.
