Solution Overview

Problem

Current digital ticketing systems lack infrastructure to securely generate, validate, and track non-fungible token (NFT) event tickets, leading to issues with forgery, duplication, and inadequate tracking of ticket holders, especially in the context of ticket resale or transmission.

Innovation Solution

A decentralized access control system utilizing smart-contracts on a blockchain infrastructure, involving ticketing, promoter, and validator authorities to securely generate, manage, and validate NFT tickets, ensuring transparency and traceability through immutable data storage and transaction tracking.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional digital ticketing systems are used, then tickets can be generated and validated, but they are vulnerable to copying and forgery

Engineering Contradiction:
Improveticket authenticityVSAvoidforgery risk
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent uses blockchain technology to create a unique, non-replicable digital token for each ticket. The blockchain's immutable ledger ensures that each ticket has a unique identifier and cannot be copied or forged, as any replication would fail to match the original token's cryptographic properties stored on the chain.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The patent replaces conventional server-based ticket validation with a decentralized blockchain system. Instead of relying on centralized databases that can be hacked or manipulated, the system uses distributed ledger technology with cryptographic verification to ensure ticket authenticity and prevent forgery.

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

2Reliability

If digital tickets are hosted on servers or cloud infrastructure, then ticket validation can be performed, but complex data processing is required to guarantee privacy and security

Engineering Contradiction:
Improvedata securityVSAvoiddata processing complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent extracts sensitive data processing from centralized servers and distributes it across the blockchain network. Each validation operation is performed by verifying cryptographic proofs on the distributed ledger, eliminating the need for complex server-side data processing while maintaining security and privacy guarantees.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The blockchain system performs validation automatically through smart contracts and cryptographic verification without requiring complex external processing. The system self-validates tickets by checking their integrity and ownership against the immutable ledger, reducing the need for complex data processing infrastructure.

Inventive Principle:
Principle #25Self-service

3Loss of information

If conventional ticketing infrastructures are used, then tickets can be issued, but tracking of ticket holders in cases of resale or transmission is not possible

Engineering Contradiction:
Improveticket holder trackingVSAvoidownership traceability
Core Design Contradiction:
Loss of informationVSReliability

Solution Approach 1:

The patent implements a feedback mechanism through the blockchain ledger that continuously tracks ticket ownership and transmission history. Each transfer of a ticket is recorded on the blockchain, providing an immutable feedback loop that allows event organizers to track who currently holds the ticket and how it was transferred, ensuring reliable ownership traceability throughout the ticket's lifecycle.

Inventive Principle:
Principle #23Feedback

AI summary

It is disclosed an access control system to generate and validate event-tickets in a distributed ledger, to enable the generation and subsequent validation of event-tickets in a secure, traceable and transparent way. A ticketing authority (10) is responsible for deploying smart-contracts (11) in a blockchain infrastructure (1), which are configured to generate NFT tickets and to assign them to owner entities. In addition, a promoter authority (20) is responsible for deploying smart-contracts (21, 23, 24) in a blockchain infrastructure (1), which are configured to create events, to which the event-tickets being provided by the ticketing authority (10) will be associated. In its turn, the validator authority (30) is responsible for deploying smart-contracts (31) in a blockchain infrastructure (1), which are configured to validate an entry request, to be issued by a holder entity, and containing the NFT ticket to be validated.
