A server (20) according to an exemplary aspect of the present disclosure comprises a non-fungible token issuing unit (221), a transaction management unit (223), and a shipment management unit (225). The non-fungible token issuing unit (221) issues, in a blockchain, a first non-fungible token that is associated with the right to request delivery of an alcoholic product and a second non-fungible token that is associated with appendant data which is related to the alcoholic product. The transaction management unit (223) manages transactions of the first non-fungible token and the second non-fungible token in the blockchain. When a request for deletion of the first non-fungible token is issued in a transaction, the shipment management unit (225) provides, to a terminal of a manufacturer of the alcoholic product, an instruction to ship the alcoholic product to a delivery destination that is designated by a terminal from which the deletion request has been issued.

The method and system of secure message verification employing a security module to store message records of messages received from sender terminals in an immutable database such as blockchain. The security module also processes verification requests from recipient terminals for forwarded message received. In a verification request, the appropriate message record is identified by a hash of the forwarded message received by the recipient terminal or a message identifier appended to the forwarded message by the security module. The security module can verify the message by comparing data in the message record against data received from the recipient terminal.

Various aspects of the subject technology relate to systems, methods, and machine-readable media for prescription management using blockchains. Various aspects may include receiving a request for creating a prescription prescribing at least one medication or drug to a patient. Aspects may also include generating a prescription based on the request being signed by a private key associated with an authorized physician. Aspects may also include generating hashes for metadata corresponding to attributes of the prescription. Aspects may also include storing the hashes in a token representing the prescription on a blockchain. Aspects may include verifying, based on at least one hash, whether the token is valid when a request to redeem the prescription is made. When the prescription is indicated to be valid, the at least one medication or drug corresponding to the prescription is dispensed to the patient.
