Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional targeted advertising systems compromise user privacy by collecting and sharing viewing data, lack transparency in advertising processes, and incur high costs for advertisers due to intermediaries, while failing to effectively measure ad effectiveness.
Innovation Solution
A display device and method utilizing a blockchain network to securely transmit and reproduce targeted advertisements based on user viewing information, using smart contracts to connect devices in a chain and ensure privacy, transparency, and efficient ad delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional targeted advertising systems collect and share user data, then advertisement effectiveness is improved, but user privacy is compromised
Solution Approach 1:
A blockchain-based intermediary system is introduced between advertisers and users. The blockchain network stores and verifies viewing information without exposing raw user data, allowing advertisers to verify ad delivery effectiveness while user privacy remains protected through cryptographic hashing and decentralized storage.
Solution Approach 2:
The patent replaces the conventional centralized data collection mechanism with a blockchain-based distributed ledger system. Instead of collecting raw user viewing data in centralized databases, the system uses blockchain to immutably record and verify viewing information, substituting the mechanical data collection process with a cryptographic verification process.
2Area of stationary object
If third party intermediaries are used to broadcast advertisements, then advertisement reach is improved, but advertising costs increase
Solution Approach 1:
The patent extracts and eliminates third-party intermediary entities from the advertising distribution chain. By implementing a direct peer-to-peer communication mechanism between advertisers and display devices through the blockchain network, the system removes the middlemen who previously charged fees for ad placement and verification.
Solution Approach 2:
The blockchain network serves multiple functions simultaneously: it acts as a communication channel for ad delivery, a verification system for viewing confirmation, a data storage mechanism for viewing information, and a trust-establishment layer. This multi-functionality replaces the multiple separate services previously provided by third-party intermediaries.
3Manufacturing precision
If user viewing data is shared with advertisers, then ad targeting accuracy is improved, but transparency of advertising process decreases
Solution Approach 1:
The blockchain system implements a transparent feedback mechanism where all viewing information records are immutably stored and verifiable by any participant in the network. Advertisers can query the blockchain to verify viewing confirmations and targeting accuracy, while the decentralized nature of the ledger ensures process transparency through cryptographic proof of data integrity.
