Solution Overview

Problem

Conventional security approaches for authentication, such as username-password combinations and cryptographic hash functions, are vulnerable to brute-force attacks and reverse engineering, as they do not effectively protect against data breaches when databases are compromised.

Innovation Solution

The implementation of wavelet transformation techniques for encrypting cryptographic information, which involves generating modified cryptographic information, converting it into matrix codes, applying wavelet transformations to create multiple data bands, and encoding the selected band for secure storage and authentication.

1Reliability

If conventional cryptographic hash functions are used for authentication, then authentication can be performed, but the system is vulnerable to brute-force attacks and reverse engineering

Engineering Contradiction:
Improveauthentication securityVSAvoidbrute-force attack vulnerability
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent applies segmentation by dividing the cryptographic information into multiple frequency bands through wavelet transformation. Instead of storing and processing a single hash value, the system transforms the credential into multiple bands (approximation and detail coefficients), making it difficult for attackers to reverse-engineer the original credential even if they obtain some band data.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent transitions from conventional one-dimensional hash functions to multi-dimensional wavelet transformation. By converting cryptographic information into a multi-band frequency domain representation, the system adds dimensional complexity that prevents traditional brute-force attacks from being effective, as attackers would need to compromise multiple bands simultaneously to reconstruct the original credential.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Ease of operation

If username and password databases are stored conventionally, then user authentication can be processed, but security issues arise when the database is compromised

Engineering Contradiction:
Improveauthentication processingVSAvoiddatabase compromise vulnerability
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent segments the stored authentication data into multiple wavelet bands, so that even if the database is compromised and attackers obtain the stored bands, they cannot easily reconstruct the original password without compromising all bands. This segmentation protects against database breaches while maintaining authentication functionality.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent changes the parameter representation of cryptographic information from conventional hash values to wavelet transformation coefficients. This parameter transformation ensures that stored authentication data does not directly reveal the original credential, reducing the impact of database compromises while allowing efficient authentication verification.

Inventive Principle:
Principle #35Parameter changes

3Productivity

If cryptographic information is transformed into simple hash strings, then authentication can be verified, but reverse engineering can extract user credentials

Engineering Contradiction:

Core Design Contradiction:
ProductivityVSLoss of information

Solution Approach 1:

The patent moves authentication verification from conventional one-dimensional hash comparison to multi-dimensional wavelet coefficient comparison. This dimensional change maintains verification efficiency while preventing reverse engineering, as the wavelet transformation creates a complex multi-band representation that is computationally infeasible to reverse-engineer compared to simple hash strings.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

AI summary

Methods, apparatus, and processor-readable storage media for encryption using wavelet transformation are provided herein. An example computer-implemented method includes generating a modified item of cryptographic information by randomly incorporating one or more characters into a user-provided item of cryptographic information; converting the modified item of cryptographic information to a matrix code; creating multiple bands of data by applying wavelet transformation to the matrix code; generating one or more encrypted items of cryptographic information by converting a selected one of the multiple bands of data into a sequence of multiple characters by applying an encoding process to the selected band of data; and storing the encrypted items of cryptographic information in a database for use in authentication requests.
