Solution Overview

Problem

Current digital ticketing systems lack infrastructure to support non-fungible token (NFT) ticketing, which is not widely adopted due to insufficient solutions for secure, transparent, and efficient generation, authentication, and tracking of event tickets, especially in the context of access control scenarios.

Innovation Solution

A decentralized system using smart-contracts on a blockchain infrastructure for generating NFT event tickets, involving a ticketing authority and promoter authority, ensuring secure, traceable, and transparent ticket generation, ownership, and access control through unique identifiers and permission levels.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional digital ticketing is used, then ticket generation is simple, but tickets can be copied and forged, compromising security and authenticity

Engineering Contradiction:
Improveticket authenticityVSAvoidinfrastructure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent introduces a blockchain infrastructure as an intermediary layer between the ticketing authority and ticket holders. This blockchain network with distributed ledger technology acts as a mediator that records ticket issuance and ownership transfers immutably, preventing forgery while maintaining a relatively simple ticket generation process at the application level.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces conventional centralized database mechanisms with a decentralized blockchain system. Instead of relying on traditional server-based authentication and ticket validation, the system uses cryptographic proofs and distributed consensus mechanisms inherent to blockchain technology to guarantee ticket authenticity and prevent duplication.

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

2Reliability

If NFT ticketing on blockchain is implemented, then fraud and forgery are reduced, but infrastructure complexity increases due to lack ofๆˆ็†Ÿ solutions

Engineering Contradiction:
Improveanti-fraud capabilityVSAvoidsystem infrastructure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent segments the ticketing system into distinct functional modules: a ticketing authority module for issuing NFTs, an event management module for organizing events, a validation module for checking ticket authenticity, and a transfer module for handling ticket resale. Each module operates independently on the blockchain infrastructure, reducing overall system complexity while maintaining high anti-fraud capability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent implements self-service mechanisms where the blockchain smart contracts automatically handle ticket validation, ownership verification, and transfer recording without requiring complex manual intervention. The system self-regulates through programmed logic embedded in the blockchain, reducing infrastructure complexity while ensuring reliability.

Inventive Principle:
Principle #25Self-service

3Ease of operation

If centralized server hosting is used, then data processing can be controlled, but privacy and security requirements lead to complex and time-consuming processing

Engineering Contradiction:
Improvedata processing efficiencyVSAvoiddata privacy and security
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent extracts sensitive ticket data from centralized servers and stores it on a distributed blockchain ledger. By taking ownership and control of ticket data out of the centralized environment and distributing it across the blockchain network, the system achieves both improved data privacy through decentralization and maintained processing efficiency through smart contract automation.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent creates a universal blockchain-based ticketing system that handles multiple functions including ticket issuance, ownership transfer, validation, and resale through a single decentralized infrastructure. This multi-functional approach eliminates the need for separate systems for each function, improving ease of operation while maintaining strong privacy and security guarantees through the blockchain's inherent properties.

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

4Reliability

If basic NFT ticketing solutions are used, then some security improvements are achieved, but complete access control scenarios cannot be handled

Engineering Contradiction:
Improveticket securityVSAvoidaccess control functionality
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent implements dynamic access control capabilities where ticket permissions can be programmatically adjusted based on event requirements. The system supports different ticket types (general admission, VIP, timed entry), transferable ownership, and conditional access rules that can be modified through smart contracts, providing both high security and versatile adaptability for various access control scenarios.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent utilizes parameter changes in the NFT metadata and smart contract configurations to enable different access control modes. By varying parameters such as ticket validity periods, entry conditions, transfer restrictions, and permission levels, the system maintains strong security foundations while adapting to diverse event requirements and access control needs.

Inventive Principle:
Principle #35Parameter changes

AI summary

The present application relates to a system for generating event-tickets in a distributed ledger, and discloses an infrastructure and processing scheme involving different computational authorities (10, 20). A ticketing authority (10) deploys smart-contracts (11) in a blockchain (1), which are configured to generate NFT tickets and to assign them to owner entities, according to a particular set of rules. In addition, a promoter authority (20) deploys smart-contracts (21, 23) in the blockchain (1), which are configured to create events according to a particular set of rules, and to which the event-tickets being provided by the ticketing authority (10) are to be associated. Due to the execution and deployment of smart-contracts, the rules involved in both the event and event-ticket generation process, as well as the access to the respective metadata, reside in an immutable form on the blockchain (1), thus enabling a secure, traceable and transparent solution for generating event-tickets.
