Solution Overview

Problem

In Web3, the lack of a single source of truth for cybersecurity poses challenges in protecting users from scams, particularly in decentralized applications where malicious frontends can steal assets by connecting to legitimate smart contracts, leading to significant damages, especially with non-fungible tokens (NFTs).

Innovation Solution

A method involving intercepting data connections to decentralized applications, using machine learning algorithms to determine the reputation of web objects, and blocking or allowing connections based on trustworthiness scores, preventing fraudulent transactions by validating the legitimacy of entry points and smart contracts.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If decentralized applications are used in Web3, then user control over identities and autonomy are improved, but cybersecurity reliability deteriorates due to lack of intermediaries to provide recourse in attacks or key compromises

Engineering Contradiction:
Improveuser control over identitiesVSAvoidcybersecurity reliability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent introduces a reputation system as an intermediary layer between users and decentralized applications. This system evaluates and scores the trustworthiness of web objects and smart contracts without replacing user autonomy. The reputation intermediary provides recourse mechanisms by allowing users to make informed decisions about which applications to interact with, thus resolving the contradiction between user control and security reliability.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system performs preliminary reputation assessment of web objects and smart contracts before users interact with them. By evaluating trustworthiness in advance and making reputation scores available beforehand, users can avoid malicious applications before encountering security issues, thus maintaining both user autonomy and security reliability.

Inventive Principle:
Principle #10Preliminary action

2Reliability

If reputation evaluation systems are implemented, then cybersecurity protection is improved, but system complexity increases due to additional evaluation layers

Engineering Contradiction:
Improvecybersecurity protectionVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The reputation system operates autonomously by automatically evaluating web objects and smart contracts without requiring manual intervention. The system self-manages the complexity of reputation evaluation through automated machine learning models and data collection mechanisms, providing cybersecurity protection while keeping the user interface simple and straightforward.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces manual security verification processes with automated machine learning-based reputation evaluation. This substitution of mechanical human review with algorithmic assessment reduces system complexity from the user perspective while maintaining or improving cybersecurity protection through consistent, scalable automated evaluation.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Object-affected harmful factors

If data connections are intercepted and evaluated, then fraudulent transactions are prevented, but loss of information increases due to potential blocking of legitimate connections

Engineering Contradiction:
Improvefraudulent transaction preventionVSAvoidlegitimate connection blocking
Core Design Contradiction:
Object-affected harmful factorsVSLoss of information

Solution Approach 1:

The system implements feedback mechanisms where reputation scores are continuously updated based on user interactions and outcomes. When legitimate connections are initially blocked, the system learns from this feedback and adjusts its evaluation criteria. This feedback loop reduces false positives by refining the distinction between fraudulent and legitimate transactions over time, preventing fraud while minimizing blocking of legitimate connections.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system applies preliminary reputation assessment to identify and block potentially fraudulent connections before they can cause harm. By evaluating trustworthiness in advance and only blocking connections below certain reputation thresholds, the system prevents fraudulent transactions while allowing legitimate high-reputation connections to proceed without interference.

Inventive Principle:
Principle #9Preliminary anti-action

AI summary

A method, apparatus, and a computer-readable medium for a web object reputation processing, especially in Web3. The method includes: intercepting (102) data transmitted in a data connection related to a current decentralized application running in a user apparatus, wherein the current decentralized application comprises a frontend implementing a web user interface for a user of the user apparatus, and a backend implemented as a smart contract; determining (110) a reputation of a web object related to the frontend of the current decentralized application; and in response to determining (110) that the reputation of the web object is malicious (114-MALICIOUS), blocking (116) the data connection.
