We can apply the concept of Blockchain to the tourism industry to prevent the counterfeiting of illegal tour guide licenses, fake guides, and fake doctors by refining the operational steps to suit the tourism context, as follows:

1. Registration and License Issuance

• Relevant tourism agencies (such as the Department of Tourism) will record tour guide license data and related information onto the Blockchain system.
• Data recorded could include
  • Full name
  • Identification number
  • Date of birth
  • Address
  • Phone number
  • Educational information
• This information will be encrypted and stored in a 'Block' on the Blockchain.
• Unique QR Codes will be generated for each license and linked to the corresponding data on the Blockchain.

2. Data Storage and Distribution

• The license information will be stored within the Blockchain, a decentralized database.
• The data is replicated and stored across multiple nodes throughout the Blockchain network, making the information highly secure and extremely difficult to modify or counterfeit.

3. License Verification

• Tourists or related parties can use a smartphone application to scan the QR Code on the tour guide's identification card.
• The application will retrieve license data from the Blockchain and display it on the smartphone screen.
• Verifiers can check the license information, qualifications, and history to confirm its validity and authenticity.
• If the displayed information does not match the data recorded in the Blockchain, the system will alert that the license is counterfeit.

4. Event Management and Alerting

• If there is an attempt to modify or forge data in the Blockchain, the system will immediately detect and alert.
• If tourists or related parties report a counterfeit license, the system will record the report data on the Blockchain for verification and further action.

The benefits

• Transparency Tourists and relevant parties can transparently verify license information.
• Security Data on the Blockchain is highly secure and difficult to counterfeit.
• Trust To establish credibility for the tourism industry and its staff.
• Verification Licenses can be verified quickly and accurately.
• Anti-Counterfeiting Reduce the problem of counterfeit and illegal tour guide licenses effectively.
• Tourist safety Tourists are confident in the safety and services they receive.

Blockchain applications in the tourism industry

• Develop a license verification application Develop a user-friendly application for tourists and related parties to verify licenses.
• Establish data connections with relevant parties Establish a data connection system with the Department of Tourism and other relevant agencies.
• Develop QR Code standardization Establish standardized QR Codes for various licenses to enable nationwide verification.
• Knowledge sharing and usage promotion Organize educational activities and promote the use of Blockchain technology in the tourism industry.

The application of Blockchain technology in tourism significantly increases the credibility of Thailand's tourism industry and greatly enhances tourist confidence.
