One of the methods includes: obtaining a testing configuration from a configuration file, wherein the testing configuration specifies a cryptography algorithm used in the blockchain system, a group of one or more private keys corresponding to the cryptography algorithm, and a predetermined execution result based on the cryptography algorithm and the group of one or more private keys; signing a transaction, by encrypting data representing the transaction based on the cryptography algorithm and the group of one or more private keys, to generate one or more signed transactions; sending the one or more signed transactions to the blockchain system and receiving an execution result from the blockchain system; and determining whether the predetermined execution result is satisfied based on the execution result.

Abstract: A transmission pairing system may include a transmission pairing stored in a secure database. The system may generate a transmission pairing by receiving a selection of a destination for the secure information from the secure database and determining a transmission type corresponding to the selected destination. The system may populate a list of available sources of the secure information based on the transmission type. A selected source may be received and paired with the selected destination to generate the transmission pairing. The transmission pairing may be used to initiate an electronic transmission based on a parameter that is modifiable to determine the secure information transmitted from the source to the destination.

Abstract: Described is cryptographically managed telecommunications settlement occurring in real time with generation and termination of a telecommunications channel. Upon the generation of a communications channel, a contract fund is established between two or more telecommunications services and recorded on a cryptographic ledger. Over the course of regular intervals of channel service, cryptocurrency is released from the contract fund. Upon termination of the communications channel, the released amount of the contract fund is transferred to the receiving provider telecommunications, the remainder back to the requesting telecommunications service. Transactions between cryptocurrency wallets are all published to the cryptographic ledger.

Abstract: Embodiments leverage the PCI-DSS validation of a backend transaction processing system to avoid the payment application having to meet the PCI compliance reporting requirements of the PCI-DSS. When the payment application needs to collect Sensitive Data for a transaction, the payment application makes a request to the payment library, which in turn requests from the backend system a secure web page including fields for the user to enter the specific Sensitive Data to be collected and typically also including a public encryption key generated specifically for the secure web page. The payment library causes the secure web page to be rendered, thereby allowing the user to enter the required information. Upon completion of such data entry, the data entered via the secure web page is pushed back through the payment library to the backend system for processing. The backend system can decrypt the encrypted data using the private key associated with the public/private encryption key pair.

Abstract: An approval request is transmitted for a cryptoasset transaction in accordance with a policy stored in a hardware security module (“HSM”). The policy specifies at least one specific approver required for approval of the cryptoasset transaction. The approval request is transmitted to a computer device associated with the specific approver and is configured to cause the computer device to prompt the specific approver to approve the cryptoasset transaction. A security key is received from a hardware security token associated with the specific approver. The security key indicates an approval of the cryptoasset transaction. A risk analysis module authenticates an identity of the specific approver based on the security key. Responsive to the authenticating of the identity of the specific approver, the HSM signs the cryptoasset transaction using a cryptographic key stored in the HSM.

Abstract: A cryptographic method of performing a tokenised transaction between a payment offering party and a payment accepting party is described. The tokenised transaction is mediated by a transaction scheme. The payment accepting party is provided with a merchant identity and a merchant certificate associated with that identity by the transaction scheme provider. The payment accepting party provides the merchant identity and transaction seed data to the payment offering party. The payment offering party validates the merchant identity and uses the merchant identity and the transaction seed data to generate a cryptogram for the tokenised transaction. The payment offering party provides the cryptogram to the payment accepting party for transmission to the transaction scheme provider for authorisation of the tokenised transaction. A suitable user computing device and merchant computing device for acting as payment offering party and payment accepting party respectively are also described.

Abstract: Systems and methods are described for providing media recommendation to a user based on analyzing a blockchain ledger. A user interest score that represents interest of the user in media assets associated with a first keyword is stored. A blockchain ledger is accessed. The blockchain ledger includes multiple blocks, each block identifying: (1) a media asset; (2) a seller user; and (3) buyer user. A blockchain ledger is searched to find a block that: (1) identifies a first media asset that comprises metadata which includes the first keyword; and (2) identifies the user as the seller. The user interest score is then reduced based on such a block being found. A media asset recommendation is then provided to the user based on the user interest score.
