Secure Hotel Check-in System Using Verifiable Credentials (VC)

Overview​

Hotels handle sensitive guest information during the check-in process, making security a top priority. Your challenge is to design a secure check-in system for hotels that leverages Verifiable Credentials (VC) issued by the government. The government of the guest's country will issue a VC Passport for travelers, and when they check into a hotel, the hotel will verify their credential and check its status from a list (valid, invalid, or under review). This ensures a seamless, secure, and privacy-focused check-in process.

Prizes​

  • 1st place: $1,000 USD + $1,800 USD in credits for the Extrimian Platform
  • 2nd place: $1,800 USD in credits for the Extrimian Platform
  • 3rd place: $480 USD in credits for the Extrimian platform

Extrimian platform credits are for 1 year, equivalent to Extrimian’s Tier 2 plan. Credits will be distributed by sponsor.

Submission requirements​

  • Use ID Connect by Extrimian to create both the credential issuer (government) and verifier (hotel).
  • The system must include the following components:
    • Credential Issuer: The government entity issues the VC Passport to the traveler.
    • Credential Verifier: The hotel validates the VC when a guest checks in, ensuring it is genuine and up-to-date.
    • Status Check: The system should check the credential’s status from a status list
    • Upon successful verification, the guest is cleared to check in.
  • W3C-compliant verifiable credentials.
  • 3-minute video describing the application and its functionality.
  • URL to the public code repository.
  • Text description of:
    • Project's features and functionality.
    • How DIDs, VCs, and other submission requirements were used in the application.
