Solution Overview

Problem

The increasing resistance to the use of cookies for collecting personal preferences, especially with the restriction or prohibition of third-party cookies, poses challenges for ad targeting and user behavior tracking.

Innovation Solution

A blockchain-based member tracking system that records user behavior using a blockchain wallet, allowing user data to be collected and utilized across multiple websites without relying on cookies. This system includes an advertising database, advertising modules, primary and secondary member databases, and a blockchain module that generates preference tags and point data associated with user behavior.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If cookies are used to collect user data for ad targeting, then ad targeting accuracy is improved, but user privacy protection deteriorates

Engineering Contradiction:
Improvead targeting accuracyVSAvoiduser privacy risk
Core Design Contradiction:
Measurement precisionVSObject-affected harmful factors

Solution Approach 1:

The patent introduces a blockchain-based wallet system as an intermediary between users and advertising systems. The wallet stores encrypted user preferences and behavior data, acting as a mediator that enables ad targeting without direct access to raw user data by third-party cookies. This resolves the contradiction by maintaining targeting accuracy through encrypted data access while protecting user privacy through cryptographic security.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent extracts the essential function of cookie-based tracking (collecting user preferences) and separates it from the harmful aspect (third-party access to raw data). By storing only encrypted preference tags and behavior data in the blockchain wallet rather than raw personal information, the system achieves ad targeting functionality while eliminating privacy risks associated with direct data access.

Inventive Principle:
Principle #2Taking out (Extraction)

2Adaptability or versatility

If third-party cookies are used for cross-website tracking, then user behavior tracking capability is improved, but user control over personal data deteriorates

Engineering Contradiction:
Improvecross-website tracking capabilityVSAvoiduser control over personal data
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent implements self-service by giving users direct control over their blockchain wallet and the data stored within it. Users can independently manage their preference tags, view their behavior data, and control which data is shared with advertisers. This eliminates the need for third-party cookie management while maintaining cross-website tracking capability through user-controlled encrypted data access.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent performs preliminary action by pre-storing encrypted user preferences and behavior data in the blockchain wallet before any advertising interactions occur. This allows the system to maintain cross-website tracking capability across multiple sites without requiring real-time cookie exchanges, as the encrypted data is already prepared and stored in the user's wallet for secure access.

Inventive Principle:
Principle #10Preliminary action

3Object-affected harmful factors

If blockchain wallet system is implemented for cookieless tracking, then user privacy protection is improved, but system complexity increases

Engineering Contradiction:
Improveuser privacy protectionVSAvoidsystem architecture complexity
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The patent applies universality by making the blockchain wallet serve multiple functions: it stores user preferences, tracks behavior data, manages encryption keys, and controls data access permissions all in a single system. This multi-functionality reduces the need for separate complex systems for each function while maintaining strong privacy protection through the unified blockchain infrastructure.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

A blockchain-based member tracking system, communicatively connected to multiple web servers and multiple user devices, comprises an advertising database, multiple advertising modules, a primary member database, and a blockchain module. The advertising modules are configured to run on the web servers and are configured for displaying the advertising data. When the user device connects to the web server, the blockchain module generates a set of the preference tags and a set of the point data, and associates them with the corresponding member data of the user device. When the user device connects to the web server, the advertising module selects the advertising data based on the corresponding member data and the preference tags. The preference tags are a form of non-fungible token data.
