Solution Overview

Problem

Existing platforms in the global advertisement market lack efficient distribution of advertisements to the right audience due to the lack of user data and do not allow end users to control the ownership or revenue generated from their personal data.

Innovation Solution

A decentralized broker system is implemented to facilitate secure usage and control of user data, involving data certificate providers, token managers, advertisement advisors, publishers, and user devices, using verifiable authentication certificates and blockchain-based smart contracts to manage and distribute advertisement tokens securely.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If user data is collected and stored in centralized repositories for advertisement distribution, then advertisement targeting capability is improved, but user control over personal data is lost and security risks increase

Engineering Contradiction:
Improveadvertisement targeting capabilityVSAvoiduser data security and control
Core Design Contradiction:
Measurement precisionVSReliability

Solution Approach 1:

The patent segments user data control by issuing individual tokens to users for their own data. Each user becomes an independent data holder with granular control over their specific data types, rather than centralized storage. This segmentation enables precise advertisement targeting through token-based permissions while maintaining user security and control.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces blockchain technology as an intermediary layer between users and advertisers. The blockchain network mediates data access by verifying token ownership and permissions without requiring centralized data repositories, thus improving targeting capability while preserving user control and security through decentralized verification.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If decentralized broker system is implemented for secure data usage, then user control and data security are improved, but system complexity increases

Engineering Contradiction:
Improveuser data security and controlVSAvoidsystem architecture complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent creates a universal token standard that can represent various types of user data (location, preferences, behavior) across different applications and platforms. This multi-functional token system simplifies the decentralized architecture by providing a single mechanism for data representation, access control, and transaction management, reducing overall system complexity despite the decentralized nature.

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

Solution Approach 2:

The patent implements feedback mechanisms through the blockchain network that automatically verify token permissions and enforce access rules. This automated feedback loop reduces the need for complex manual security management and simplifies the system by using cryptographic verification instead of elaborate access control systems.

Inventive Principle:
Principle #23Feedback

3Ease of operation

If tokens are generated and registered on blockchain for each user data, then user control and revenue distribution are improved, but processing time and computational resources increase

Engineering Contradiction:
Improveuser control over dataVSAvoiddata processing time
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The patent performs preliminary actions by issuing tokens to users during initial data collection or profile creation, rather than creating tokens on-demand during advertisement transactions. This advance preparation stores user data preferences and permissions in the blockchain, enabling rapid transaction processing later without repeated computational overhead for token generation.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent uses cryptographic copying where the blockchain stores hash references and permission metadata rather than duplicating actual user data. This approach maintains user control through token ownership while minimizing processing time by working with compact cryptographic representations instead of large data sets.

Inventive Principle:
Principle #26Copying

AI summary

The present disclosure describes techniques for using online data in a secure environment. A token may be generated based on a user's behavior data. The token may be certified by a data certificate provider. The token may be registered through a decentralized service provided by a broker. The broker may be configured to process advertising requests received from advertisers. The broker may be configured to request for advertisements suggested by at least one independent advisor. The broker may be configured to provide at least one subset of the advertisements to at least one publisher. The token may be transmitted to an independent token manager for storage. An ownership of the token may be claimed when interacting with the at least one publisher. The ownership of the token may be verified after the at least one publisher plays at least one advertisement associated with the token.
