Abstract
A vaccine system implementing a secure vaccine service to provide vaccine accounts for users, includes a display and user interface component providing user access to the vaccine service; a communications component providing third-party access to the vaccine service; a processor; and a non-transitory, computer readable storage medium having encoded thereon, machine instructions for operating the vaccine service. The processor executes the machine instructions to establish a secure vaccine account for the user, receive a vaccine transaction on behalf of the user, the vaccine transaction including a vaccine data package. The vaccine data package includes certified data for one or more vaccines administered to the user, the vaccine transaction provided by a medical facility administering the vaccines. The processor assigns a hash to the received vaccine transaction, and stores the hash and the vaccine data package in a block in a distributed ledger-architected database.
Core Innovation
A secure vaccine service system is configured to generate and verify tamper-evident digital records of vaccine administration for use in automated venue access decisions. The system establishes a secure vaccine account for a user, receives a vaccine transaction comprising certified data, and generates a first one-way cryptographic hash of the certified data. The certified data is stored in an off-chain database file indexed by a user identifier, and the first one-way cryptographic hash is stored in a first block of a distributed ledger-structured database with a reference to the off-chain database file.
A venue control application transmits a venue access request comprising the user identifier and an authorization digital object to access the secure vaccine account of the user. In response, the application receives a copy of the certified data and contents of the first block, receives a confirming one-way cryptographic hash of the copy of the certified data, compares the first one-way cryptographic hash and the confirming one-way cryptographic hash, and permits venue access when the hashes match exactly. The system provides a record of the venue access to the vaccinated user sub-system.
The claimed method and related non-transitory computer readable medium likewise include receiving a vaccine transaction on behalf of the user from a medical facility administering one or more vaccines, storing the certified data in an off-chain database file linked to the user, and storing the first and second one-way cryptographic hashes in blocks of a distributed ledger-structured database referenced by the user identifier or off-chain database file. The system also verifies credentials of a third party, disseminates data to a venue control component, and uses an exact hash match to indicate unaltered certified data.
Claims Coverage
The partial content provides three independent claims: clm-00001, clm-00018, and clm-00020. Each independent claim centers on one-way cryptographic hashes linked between off-chain certified data and blocks of a distributed ledger-structured database, with venue access conditioned on exact hash match verification and ledger recordkeeping of access events.
Tamper-evident off-chain certified vaccine records with one-way hash reference to distributed ledger
Establish a secure vaccine account for the user; receive a vaccine transaction comprising certified data; generate a first one-way cryptographic hash of the certified data comprising a tamper-evident digital record; store the certified data in an off-chain database file indexed by a user identifier; and store the first one-way cryptographic hash in a first block of a distributed ledger-structured database with a reference to the off-chain database file.
Automated venue access decision via exact one-way hash match verification
Transmit a venue access request comprising the user identifier and an authorization digital object; receive, in response, a copy of the certified data and contents of the first block comprising the first one-way cryptographic hash; receive a confirming one-way cryptographic hash of the copy of the certified data; compare the first one-way cryptographic hash and the confirming one-way cryptographic hash; permit venue access when the first one-way cryptographic hash and the confirming one-way cryptographic hash match exactly; and provide a record of the venue access to the vaccinated user sub-system.
Third-party access verification and dissemination using hash comparison to indicate unaltered certified data
Establish a secure vaccine account for a user; receive a vaccine transaction comprising certified data from a medical facility; store the certified data in an off-chain database file linked to the user; generate and store a first one-way cryptographic hash in a first block of a distributed ledger-structured database with a reference to the off-chain database file; verify credentials of the third party; for a verified third party disseminate data comprising the first one-way cryptographic hash and the certified data to a venue control component; receive an exact-match confirming one-way cryptographic hash comparison result indicating unaltered certified data; receive a second one-way cryptographic hash of the certified data and the third party access; generate a second block to contain the second one-way cryptographic hash of the certified data and the third party access; and store the second block with a reference to the off-chain database file.
Across clm-00001, clm-00018, and clm-00020, the inventive concept is anchored in storing certified vaccine data off-chain while anchoring tamper-evident one-way cryptographic hashes in a distributed ledger-structured database, and using exact one-way hash comparisons, including a confirming one-way cryptographic hash, to drive automated venue access and record access-related information in ledger blocks.
Stated Advantages
Provides automated venue access decisions based on tamper-evident digital records of vaccine administration.
Enables verification that certified vaccine data is unaltered by requiring an exact match between the stored one-way cryptographic hash and a confirming one-way cryptographic hash.
Stores a record of venue access and access-related information in a distributed ledger-structured database.
Documented Applications
Automated venue access decisions using tamper-evident digital records of vaccine administration.
