An information transaction method of the present disclosure includes an information providing phase of providing, by an information provider, information requested by an information user via a distributed ledger of authentication server devices. In the information providing phase, an information provider terminal acquires first transaction data including an information user ID, an information provider ID, and a second information index indicating an index of first information requested by the information user among information items indicated by the first information index published in the distributed ledger, the first transaction data being written in the distributed ledger. The information provider terminal generates first encrypted information by encrypting the first information designated by the second information index, generates second transaction data including the information provider ID, the information user ID, and the first encrypted information, and transmits the second transaction data to an authentication server device.

An inspection assistance system includes an inspection display processing part which is configured to display, per unit of packing, a capture image of a tablet which is captured before the tablet dispensed from one or both of a tablet cassette and a manual distribution unit based on prescription data is packed into a packing material in a tablet packing device, and is configured to display a result of an inspection process which is executed based on the prescription data and identification information of the tablet included in the capture image of the tablet. Thus, it is possible to assist a pharmacist's inspection task carried out with respect to the tablets packed by the tablet packing device.

The present disclosure provides a transaction processing method, a transaction processing apparatus, an electronic device, and a storage medium, relating to the technical field of encrypted communications. The transaction processing method includes: constructing a payment transaction; obtaining a digital signature of the payment transaction based on a private key of a payer and storing the digital signature of the payment transaction; and broadcasting the payment transaction and the digital signature thereof to an account book network, so that a payee receives the payment transaction and the digital signature thereof from the account book network, constructs a collection transaction corresponding to the payment transaction after the validity is passed using a public key of the payer, and obtains a digital signature of the collection transaction based on a private key of the payee.

The present invention relates to a digital virtual currency transaction system and method which enable a receiver to make digital virtual currency transactions having a block chain regardless of whether an electronic wallet has been opened, and which have a block chain between concerned parties to guide the concerned parties to be able to conveniently make URL-based transactions without recognizing a public address comprised of 32 bytes or more for every digital virtual currency transaction having a block chain between concerned parties. Provided are a system and a method using same, the system comprising: a block chain-based digital virtual currency transaction guide server (100); a giver terminal (200) which is loaded with a giver-side block chain-based digital virtual currency transaction app (210), generates a giver transaction request signal; and a receiver terminal 300 which clicks the receiver transaction selecting URL (A).

A client, a server, a method and an identity verification system are provided. The client is configured to generate a verification code and includes: a transaction initiating unit configured to initiate, in response to a predetermined identity verification event regarding a user, a random transaction between a first account and a second account in a data platform system, so that the random transaction is recorded in the data platform system; a verification code generating unit configured to generate, based on at least information about the random transaction, a verification code for verifying an identity of the user; and a sending unit configured to send the generated verification code to a server, so that the server verifies the identity of the user according to a record of the random transaction and the verification code, the data platform system being a decentralized distributed database and records therein being unchangeable and undeletable.

A method for generation of an application cryptogram for use in a payment transaction includes: storing, in a first memory, a single use key associated with a transaction account; electronically transmitting the single use key to a processing server; receiving an encrypted session key and a server encryption key from the processing server; executing a first query to store the encrypted session key in the first memory and a second query to store the server encryption key in a second memory; decrypting the encrypted session key using the server encryption key; generating an application cryptogram based on the decrypted session key; and electronically transmitting the generated application cryptogram for use in a payment transaction.

A method for mediating virtual asset transmission is provided. The method comprises receiving a first information on virtual asset to be transmitted from a first user to a second user from a first virtual asset service provider (VASP) server managing virtual asset of the first user, transmitting a verification request as to whether information on the second user included in the received first information is correct to a second VASP server managing virtual asset of the second user, receiving a verification result indicating that the information on the second user is correct from the second VASP server as a response to the verification request, and transmitting the received verification result to the first VASP server. The method further comprises transmitting virtual asset update request of the second user to the second VASP server if it is determined that the transaction has been recorded in the blockchain.

Systems and methods are provided for updating a vehicle record maintained in an MVD database through the steps of: issuing a temporary registration permit (TRP) at a dealer; issuing a title and a registration at a fiduciary; recording a lien associated with the title; and releasing the lien.

A user is authenticated for a session with a server, the server generates a unique session token valid during an active session with the server. Valid outstanding transactions for the active session are presented to the user. A selected outstanding transaction is provided to a Self-Service Terminal (SST) with the unique session token. The SST validates the unique session token and the selected outstanding transaction with the server. Upon confirmation from the server, the SST completes the selected outstanding transaction at the SST.

Various examples are directed to computer-implemented systems and methods for authentication of financial transactions. The method includes receiving a request from an initiation point to authenticate a user to perform a transaction, and obtaining device data gathered by internet-enabled devices used by the user. Third-party data is received from a third party in response to a third-party authorization inquiry, and a processor located at a decision point uses the device data and the third-party data to authenticate the user for the transaction.
