BLOCKCHAIN-BASED SUPERVISION METHOD FOR ELECTRONIC IMMUNITY PASSPORT - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240348455 titled 'BLOCKCHAIN-BASED SUPERVISION METHOD FOR ELECTRONIC IMMUNITY PASSPORT
The invention provides a blockchain-based supervision method for an electronic immunity passport. A certificate authority generates and distributes public-private key pairs. A hospital generates an immunity passport for a vaccine, encrypts it, and uploads transactions to national and world alliance chains. When the vaccine is requested, the vaccinee provides a passport number and uploads a trapdoor to the world alliance chain for decryption. Alliance chain nodes perform maintenance through smart contracts, ensuring data openness, traceability, and immutability.

Benefits: - Enhanced security and privacy of immunity passport data - Efficient maintenance and supervision of data - Reliable and traceable immunity passport information
Commercial Applications: Title: Blockchain-Based Electronic Immunity Passport Supervision Method This technology can be utilized in healthcare systems, travel industry, and border control agencies to ensure the authenticity and reliability of immunity passport data, enhancing security and traceability in various sectors.
Questions about Blockchain-Based Electronic Immunity Passport Supervision Method: 1. How does the certificate authority ensure the security of public-private key pairs? The certificate authority employs encryption algorithms and secure protocols to generate and distribute key pairs securely.
2. What are the key benefits of using blockchain technology for supervising immunity passport data? Blockchain technology ensures data immutability, traceability, and openness, enhancing the reliability and security of immunity passport information.
Original Abstract Submitted
the invention provides a blockchain-based supervision method for an electronic immunity passport. a certificate authority generates and correspondingly distributes public-private key pairs. a hospital generates an immunity passport for a vaccine and assigns a passport number; encrypts the immunity passport and the passport number; and generates and uploads a transaction to a national alliance chain node (nacn). the nacn generates and uploads a second transaction to a world alliance chain (wac). when the vaccine is requested to show the immunity passport, the vaccinee provides the passport number, generates and uploads a trapdoor to the wac. the vaccine decrypts received ciphertext from the wac to obtain plaintext data. an alliance chain node performs periodic maintenance by a smart contract. the invention can ensure data openness, traceability, and immutability, achieve effective supervision for the immunity passport data, provide reliable immunity passport data, and achieve search and regular maintenance for the immunity passport.
