Solution Overview

Problem

Existing cybersecurity measures are vulnerable to cybercrimes, particularly when user devices rely on network communications, as malicious entities can exploit unauthorized access to steal, alter, or destroy sensitive data, and the centralized security database may become unavailable, leading to potential unauthorized access and resource inefficiencies.

Innovation Solution

Implementing a method for group verification of a transmission source by transmitting verification information, including a current fingerprint of a source application, and receiving a determination result from other devices to assess whether the source application is trusted, thereby preventing unauthorized access even when the centralized security database is unavailable.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a centralized security database is used to verify transmission sources, then security verification can be performed, but the system becomes vulnerable to unauthorized access when the database is unavailable and experiences resource inefficiencies

Engineering Contradiction:

Improvesecurity verificationVSAvoidcentralized database dependency

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent segments the centralized security verification system into distributed peer verification. Instead of relying on a single centralized database, multiple user devices (peers) are divided into a network where each device can verify transmission sources independently by comparing fingerprints with its local instances, eliminating the single point of failure.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent implements local quality by enabling each user device to perform security verification using its own local resources and fingerprint database. Each device maintains local verification capabilities through the security application that stores and compares fingerprints locally, reducing dependency on external centralized systems.

Inventive Principle:

Principle #3Local quality

2Productivity

If network communication is used for data transmission, then information can be exchanged between user devices, but the communication becomes vulnerable to cybercrimes such as malware attacks and phishing

Engineering Contradiction:

Improveinformation exchangeVSAvoidcybercrime vulnerability

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The patent applies preliminary action by performing security verification before allowing data transmission. The security application verifies the transmission source by comparing fingerprints in advance, ensuring that only authenticated sources can communicate through the network, thereby preventing cybercrimes before they occur.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent implements feedback through the verification result that is communicated back to the transmitting device. The receiving device compares the transmitted fingerprint with its local fingerprint and provides feedback on whether the transmission source is verified, enabling the system to accept or reject communications based on authentication status.

Inventive Principle:

Principle #23Feedback

3Measurement precision

If fingerprint comparison is performed with multiple peer devices, then verification accuracy improves, but the time and resources required for verification increase

Engineering Contradiction:

Improveverification accuracyVSAvoidverification time

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The patent applies partial action by performing fingerprint comparison with a selected subset of peer devices rather than all possible peers. The system transmits verification requests to multiple peers and processes responses from those that respond, obtaining sufficient verification accuracy without requiring exhaustive comparison with every device in the network.

Inventive Principle:

Principle #16Partial or excessive action

AI summary

The present disclosure discloses configuring a transmitting device to determine verification information including a current fingerprint associated with a first instance of a source application stored on the transmitting device, the current fingerprint (i) being determined based on utilizing one or more connection parameters associated with an external device communicating with the first instance of the source application, and (ii) uniquely identifying the first instance of the source application; configuring the transmitting device to transmit verification information including the current fingerprint; configuring the transmitting device to receive a determination result determined by the receiving device based on a comparison of the current fingerprint with a verification fingerprint that uniquely identifies a second instance of the source application stored on another device; and configuring the transmitting device to selectively transmit transmission data utilizing the first instance of the source application based on the determination result. Various other aspects are contemplated.
