Solution Overview

Problem

Existing authentication methods rely on static security features that can be easily copied or compromised, such as PINs, biometrics, and 3D codes, which lack flexibility and are vulnerable to attacks, especially in network systems.

Innovation Solution

A method that utilizes a unique material, structure, or composition as a security feature, which changes dynamically through physical, chemical, or mechanical interactions, allowing for unpredictable changes that are stored and compared at different times to authenticate individuals or systems.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If static security features (PIN, biometric, code) are used for authentication, then authentication can be performed, but the security features can be easily copied or compromised

Engineering Contradiction:
Improveauthentication securityVSAvoidresistance to copying
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent transforms static security features into dynamic ones by introducing time-dependent changes. The security feature changes its appearance or properties over time, making it impossible for attackers to capture a valid state and replay it later. This is achieved through dynamic generation of visual patterns that evolve continuously, resolving the contradiction between maintaining authentication functionality and preventing copying.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes physical or chemical parameters of the security feature over time. By modifying properties such as color, shape, or structural configuration dynamically, the security feature becomes unpredictable and不可复制. This parameter transformation approach maintains authentication reliability while enhancing resistance to copying attacks.

Inventive Principle:
Principle #35Parameter changes

2Measurement precision

If biometric data is used for authentication, then personal identification is achieved, but the data does not change and can be copied

Engineering Contradiction:
Improveidentification accuracyVSAvoidsecurity against attackers
Core Design Contradiction:
Measurement precisionVSReliability

Solution Approach 1:

The patent combines biometric identification with dynamic visual patterns. While the biometric data provides accurate personal identification, the overlaid dynamic security feature changes continuously, preventing attackers from using static copies of biometric data alone. The dynamic component ensures that even if biometric data is compromised, it cannot be used without the corresponding time-specific visual pattern.

Inventive Principle:
Principle #15Dynamics

3Loss of information

If 3D codes with predefined structures are used, then information can be encoded, but the structure does not change and can be circumvented by attackers

Engineering Contradiction:
Improveinformation encoding capabilityVSAvoidsecurity against circumvention
Core Design Contradiction:
Loss of informationVSReliability

Solution Approach 1:

The patent transforms predefined static 3D codes into dynamic structures that change over time. The visual pattern encoded in the 3D structure evolves continuously, making it impossible for attackers to circumvent the system by analyzing a static structure. The dynamic transformation maintains information encoding capability while enhancing security against circumvention attacks.

Inventive Principle:
Principle #15Dynamics

4Ease of operation

If password-based authentication is used, then access control is implemented, but data transmissions can be intercepted and hacked

Engineering Contradiction:
Improveaccess control functionalityVSAvoidvulnerability to interception
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent replaces static password transmission with dynamic visual pattern verification. Instead of transmitting passwords that can be intercepted, the system displays continuously changing visual patterns that must be matched in real-time. This eliminates the vulnerability to interception while maintaining ease of operation, as users simply need to verify the visual pattern rather than memorize or transmit passwords.

Inventive Principle:
Principle #15Dynamics

AI summary

The invention relates to a method and to a device for authenticating and/or identifying persons, objects, or service systems. In said method, a material, a construction, a substance, or a composition, or an image thereof, either changes itself or is actively changed, by means of a physical, chemical, or mechanical influence or feature, such that the resulting structure or feature is unforeseeable. If an image of said material, of the construction, of the substance, or the composition recorded at a later time is compared with the image stored in a storage means, the person and/or the object and/or the medium and/or service system is positively authenticated if the material, the construction, the substance, or the composition has at least partially changed between the two times in comparison with the image stored in the storage means.
