This ticket validity confirmation device prepares certificate data that is associated with one ticket and that comprises a set of certificate preparation information and certificate verification information, then stores the certificate verification information in a storage device, and transmits the certificate preparation information to a ticket information processing device. The ticket information processing device prepares a ticket validity certificate on the basis of the certificate preparation information, and transmits the ticket validity certificate to the ticket validity confirmation device. The ticket validity confirmation device verifies the ticket validity certificate on the basis of the certificate verification information stored in the storage device.

A limited scope blockchain system supports onboarding and payments via linked databases including an append-only database and a secondary database holding transaction requests that have not been applied to the blockchain.

Method and apparatus for allowing the changing of security values and consent data is provided. The security values allow for dynamically changing the security level and ease of access associated with performing specific transactions on specific accounts. The consent data may be pushed or pulled and when stored, may be used for future transactions, of both the same or a different type. The changing of security levels and consent data may be accomplished over the internet using mobile devices over both secure and non-secure networks.

Methods and apparatuses for retrieving blockchain data are disclosed. One method comprises: receiving a data retrieving request that comprises a target transaction identifier; identifying a transaction storage location that corresponds to the target transaction identifier as a target transaction storage location based on a pre-stored correspondence between transaction identifiers of transactions recorded on a blockchain associated with the blockchain network and transaction storage locations of the transactions; and retrieving data from the target transaction storage location in the blockchain.

Disclosed are CodeChain-based models, apparatuses, systems, methods, and applications. When implementing interaction based on CodeChain, each digital person has identity information, the identity information corresponding to a person represented by the digital person and/or the terminal device used by the person; the method comprising: identifying, by the terminal device, a coding medium generated according to a CodeChain access protocol so as to enable the digital person to access a CodeChain network on behalf of the person; and performing data transfer with another digital person and/or system according to entrustment of the person. Through identification of the coding medium, the access address of the code chain server is obtained, and then the address of the server which actually provides services is obtained from the CodeChain server, such that the service is obtained by providing a service parameter as required.

Systems and methods for providing a report of an analytic result value based on IP data are disclosed. An example system may include a controller configured to: access a distributed ledger including a plurality of intellectual property (IP) data about a plurality of IP assets, where the IP assets include an aggregate stack of IP; tokenize the plurality of IP data; and interpret a distributed ledger operation corresponding to at least one of the IP assets. The controller may also be configured to determine an analytic result value in response to the distributed ledger operation and the tokenized plurality of IP data, where the analytic result value is one of: a number of access events, an access time; or an access processing time and to provide a report of the analytic result value; and record a transaction on the distributed ledger in response to providing the report.

A service running on a server, for example as a cloud server, that services with a guarantee from a guarantor. The service includes receiving, from a user using a zero-knowledge protocol to ensure privacy of the user, a request for a service with an associated quality level for a fee. Next, the request for service received requires a guarantee of the service requiring additional assurances based on a rating quantity available by a guarantor of the service is identified. At least a portion of the rating quantity available by the guarantor of the service is received. A notification from the user that the service is unacceptable is received. In response to the notification and a verification that the associated quality level was not met, refunding at least a portion of the fee to the user from the guarantor of the service.

The present invention discloses a method of processing a data transfer request securely over a network, the method comprising the steps of obtaining, by a first entity, a first token associated with sensitive data received from a user; associating the first token with a token reference and storing the token reference; sending the token reference to a second entity; requesting a second token from a second entity upon receiving a data transfer request from a third entity, wherein the second token is derived from the first token using an ad hoc logic; and processing the data transfer request using the second token.

Various embodiments are generally directed to NFC-based mobile currency transfers. A mobile payment may be programmatically initialized when at least two mobile devices come into NFC communications range. A payment card associated with an account used to fund the currency transfer may be tapped to one or more of the devices to allow a server to validate the currency transfer.
