Abstract: A computing node comprises a processor and a transaction cache. The transaction cache comprises one or more function records for each of a plurality of account numbers. Each function record comprises an account number, a function identifier, and transaction identifiers for any qualifying transactions. A qualifying transaction is a transaction for that account number to be used in determining a value for a function identified by the function identifier. The computing node can receive notification of an authorization request for a transaction pending authorization from a transaction network and provide values for each of the functions associated with an account number from the function record for that function using the transaction identifiers in that function record. If the transaction pending authorization is authorized, the computing node can then add a transaction identifier for that transaction to each function record for which that transaction is a qualifying transaction.

Abstract: A computer implemented method of assessing the probability of fraudulent activity in an account to account payment is provided. The method comprises determining, based on previous credit balance settlement transactions between a first account and a card settlement account, that a first set of payment credentials is associated with the first account. It is determined that a second set of payment credentials are associated with the merchant account. A database comprising historical data indicating details of past payment transactions between the holder of the first set of payment credentials to the holder of the second set of payment credentials is accessed. A fraud probability engine is used to generate, based on the historical data, a fraud probability value for a transaction from a first account to a second account, wherein the fraud probability value is an estimate of the probability of the transaction being fraudulent.

Abstract: A method for hybrid payment authorization includes: storing a merchant profile including a merchant identifier and a merchant public key; receiving an authorization request for a payment transaction including an account number from an external entity, the merchant identifier, and a transaction amount; generating a recipient blockchain address using the merchant public key; transmitting the recipient blockchain address, a blockchain amount based on the transaction amount, and a sender digital signature to a node in a blockchain network; generating an authorization response for the payment transaction including a response code indicating approval or denial of the payment transaction; and transmitting the generated authorization response to the external entity.

Abstract: A method of electronic user message protocol extension for a transaction requiring delivery is provided. The method is implemented using a message protocol extension (MPE) computing device.

Abstract: An illicit website identifying (IWI) computing device is described herein, the IWI computing device configured to store a log of suspect illicit websites, the log including website content associated with each suspect illicit website. Each suspect illicit website is associated with a respective merchant. The IWI computing device is also configured to receive transaction data for at least one transaction initiated at a first suspect illicit website, the first suspect illicit website included within the log of suspect illicit websites, and analyze the received transaction data to identify one or more transactions including at least a portion of the website content associated with the first suspect illicit website. The IWI computing device is further configured to identify the first suspect illicit website and the merchant associated therewith as illicit for further investigation, and generate an identification report including the identified illicit website and merchant.

Abstract: A system and a method for determining when a predetermined number of a specific product or of a type of product has been sold so that an alert can be generated when the number sold exceeds the predetermined number. Transaction rules can be set to monitor transaction data in a database to achieve this result. The transaction rules can be set for a generic product, for a specific product, or to exclude certain products. The system and the method issue an additional alert when data in a database indicates that the number of a specific product or of a type of product being sold in a selected time frame is below the selected predetermined number or another selected predetermined, for a selected period of time.

Abstract: The disclosure facilitates a relationship between a worker and a service provider company by determining and enforcing commission balance thresholds between the worker and the service provider company. Transaction data associated with a service request assigned to a worker account of the worker is received. The transaction data is recorded to a transaction history data structure and a commission balance threshold between the worker and the service provider company is determined based on transaction history data of the transaction history data structure. A commission balance between the worker and service provider company is updated based on the transaction data. Upon the updated commission balance exceeding the commission balance threshold, the worker account is disabled, such that the worker is prevented from receiving new service requests.
