Solution Overview

Problem

Existing systems are vulnerable to cyber-attacks that lead to data theft, as bad actors can hack into databases, networks, or monitor data interactions to steal sensitive information, and current methods fail to effectively prevent such theft.

Innovation Solution

A security manager intercepts and obfuscates sensitive data in real-time or near real-time using data obfuscation algorithms, identifies and applies varying obfuscation levels based on data sensitivity, and generates synthetic data to divert unauthorized access, thereby protecting sensitive information.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If real-time obfuscation of all data is implemented, then data security is improved, but processing time and network delay increase

Engineering Contradiction:

Improvedata securityVSAvoiddata transmission delay

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent applies different obfuscation levels to different portions of data based on sensitivity classification. High-sensitivity data receives strong obfuscation while low-sensitivity data receives minimal or no obfuscation, optimizing the balance between security and transmission speed

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The system performs partial obfuscation by selectively obfuscating only the sensitive portions of data rather than the entire data stream. This reduces processing overhead while maintaining security for critical information

Inventive Principle:

Principle #16Partial or excessive action

2Reliability

If comprehensive data obfuscation is applied, then data security is improved, but processing resources are consumed

Engineering Contradiction:

Improvedata securityVSAvoidprocessing efficiency

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The system identifies and applies obfuscation only to sensitive data portions rather than processing all data uniformly. This selective approach reduces CPU and memory resource consumption while maintaining security where needed

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The patent implements partial obfuscation by targeting only sensitive data fields identified through classification. This avoids the excessive resource consumption of obfuscating entire data streams while maintaining adequate security protection

Inventive Principle:

Principle #16Partial or excessive action

3Measurement precision

If detailed sensitivity analysis is performed on data portions, then obfuscation precision is improved, but processing complexity increases

Engineering Contradiction:

Improveobfuscation precisionVSAvoidprocessing complexity

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The system performs preliminary classification of data into sensitivity categories before obfuscation. This pre-processing step organizes data in a way that simplifies subsequent obfuscation decisions and reduces real-time processing complexity

Inventive Principle:

AI summary

In response to detecting an unauthorized access to a data network, a processor obfuscates, in real-time at least a portion of data relating to a data interaction that is transiting via a data network from a source node to a target node, wherein the obfuscating the data includes intercepting the data originating from the source node, generating obfuscated data by obfuscating the data relating to the data interaction using one or more data obfuscating algorithms, and transmitting the obfuscated data over the data network to the target node.
