Solution Overview

Problem

Existing query systems are vulnerable to man-in-the-middle attacks and resource-intensive security measures, such as encryption, which consume power and processing resources.

Innovation Solution

A method where a user device transmits duplicate queries to multiple data sources using different networks and protocols, allowing for the comparison of responses to detect attacks and conserve resources.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional encryption methods are used to secure queries, then security is improved, but power and processing resource consumption increase

Engineering Contradiction:

ImprovesecurityVSAvoidpower consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent applies copying by transmitting duplicate queries to multiple data sources instead of using encryption. The system sends identical query copies through different networks and compares responses to detect attacks, eliminating the need for computationally intensive encryption while maintaining security through response verification

Inventive Principle:

Principle #26Copying

2Reliability

If traditional encryption methods are used to secure queries, then security is improved, but processing resource consumption increases

Engineering Contradiction:

ImprovesecurityVSAvoidprocessing resources

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The system replaces complex encryption processing with simpler query duplication and response comparison. By sending multiple copies of queries through different networks and verifying response consistency, the system achieves security without the heavy processing overhead of encryption algorithms

Inventive Principle:

Principle #26Copying

3Reliability

If duplicate queries are transmitted to multiple data sources, then detection of attacks is enabled, but network traffic increases

Engineering Contradiction:

Core Design Contradiction:

ReliabilityVSQuantity of substance

Solution Approach 1:

The patent applies segmentation by dividing the security verification process into separate parallel query transmissions through different networks. Each network carries a portion of the duplicate queries, and the system segments the validation process by comparing responses from different sources, enabling attack detection while managing network traffic through distributed verification

Inventive Principle:

Principle #1Segmentation

AI summary

In some implementations, a user device may transmit, to a first data source, a first message encoding a first query and may receive a first response to the first query from the first data source. The user device may transmit, to a second data source, a second message encoding a second query that duplicates the first query and may receive a second response to the second query from the second data source. The user device may transmit a first reverse query to the first data source based on the second response and/or a second reverse query to the second data source based on the first response. The user device may receive at least one reverse query response. Accordingly, the user device may determine whether an answer to the first query is valid, based on the first response, the second response, and the at least one reverse query response.
