Solution Overview

Problem

Current authentication methods can be vulnerable to counterfeiting as static security features can be copied or circumvented with reasonable effort, lacking sufficient dynamic changes to prevent unauthorized access.

Innovation Solution

An authentication device that incorporates a security element with dynamically changing structural features, influenced by external or internal factors, which affects the appearance and detectability of characters during optical character recognition, converting them into machine-readable formats and comparing them with stored references using control devices that define detection and analysis parameters.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If static security features are used, then the authentication process is simple and readable, but the security is vulnerable to counterfeiting

Engineering Contradiction:
Improvesecurity against counterfeitingVSAvoidcomplexity of authentication process
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent applies dynamics by making the security feature's character appearance change over time through structural evolution (crackle pattern development). The control unit dynamically adjusts detection conditions and analysis parameters to recognize characters at different stages of structural development, transforming a static security feature into a dynamic one that evolves unpredictably to prevent counterfeiting

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes parameters by allowing the structural feature to evolve its physical state over time, causing characters to transition between readable and unreadable states. The control unit adapts detection and analysis parameters accordingly, changing how characters are captured and interpreted based on the current structural state, thereby creating a time-dependent authentication mechanism

Inventive Principle:
Principle #35Parameter changes

2Reliability

If dynamic structural features are introduced to prevent counterfeiting, then security is enhanced, but the character detectability and readability during authentication becomes unpredictable

Engineering Contradiction:
Improvecounterfeit protectionVSAvoidcharacter recognition accuracy
Core Design Contradiction:
ReliabilityVSMeasurement precision

Solution Approach 1:

The patent implements feedback by having the control unit continuously monitor the structural feature's state and adjust detection conditions and analysis parameters in real-time. The system receives feedback from the evolving crackle pattern and adapts its character recognition process accordingly, ensuring accurate authentication despite the dynamic and unpredictable structural changes

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent applies preliminary action by pre-defining multiple detection conditions and analysis parameters that correspond to different stages of structural feature development. The control unit selects and applies the appropriate pre-configured parameters based on the current structural state, enabling accurate character recognition without requiring real-time parameter optimization

Inventive Principle:
Principle #10Preliminary action

AI summary

The present invention relates to an authentication device and a method for authenticating or determining the identity of a person, a device, a thing, a service, an application and/or a computer program, wherein authentication is carried out via a security element (1) with at least one security feature (2) and an authentication device.In the process, a security element (1) with at least one security feature (2) consisting of characters that can be detected by character recognition is provided, the appearance of the characters of the security feature (2) is detected by a detection device, character recognition and/or character analysis is carried out in which the recognizable characters of the appearance of the security feature (2) are converted and a comparison of the security feature (2) detected by the detection device (5) and/or the characters converted by the character recognition device (6) is carried out with a reference feature stored in a memory and/or one or more reference characters and/or one or more reference tones.According to the invention, it is provided that the detection conditions for detecting the appearance of the characters and/or the reading conditions for character recognition and/or the analysis parameters for character analysis of the characters of the security feature (2) are defined, and that the security element (1) has at least one structural feature (4) which influences the appearance of the security feature (2) and thus the detectability of one or more characters of the security feature (2) during character recognition and/or character interpretation.
