Abstract: A computer-based method for associating ownership of anonymous payment cards uses a computer device including a processor in communication with a transaction database. The method includes identifying a target account number for a payment card from the transaction database, identifying a set of transaction times associated with the target account number from the transaction database, and comparing the target account number to each candidate account number of a set of candidate account numbers from the transaction database. Comparing the target account number includes identifying a first candidate set of transaction times associated with a first candidate account number of the set of candidate account numbers, comparing the target set of transaction times to the first candidate set of transaction times, and identifying the first candidate account number as a match candidate if the target set of transaction times and first candidate set of transaction times do not include overlapping transactions.

Abstract: A method for aggregating entity transaction data across multiple transaction accounts includes: storing a plurality of entity profiles, wherein each entity profile is associated with an entity including a unique entity identifier and a plurality of transaction data entries, each transaction data entry including transaction data associated with a payment transaction involving one of a plurality of transaction accounts associated with the associated entity; receiving transaction data for a processed payment transaction, wherein the transaction data includes a specific unique entity identifier associated with an entity involved in the processed payment transaction and a separate account identifier associated with a transaction account used to fund the processed payment transaction; identifying a specific entity profile where the included unique entity identifier corresponds to the specific unique entity identifier; and storing, in the identified specific entity profile, the received transaction data.

Abstract: A method for identifying a level of authentication includes: storing a plurality of authentication processes, each tool being associated with transaction characteristics; storing a plurality of account profiles, each profile including account data and an account identifier; receiving an authorization request for a payment transaction, the request including transaction data and a specific account identifier; identifying at least two eligible authentication processes based on the transaction characteristics for the respective tool and the transaction data; identifying a specific account profile that includes the specific account identifier; estimating a profitability value of the transaction based on the transaction data; estimating an account purchase elasticity value based on the account data included in the identified specific account profile; and selecting one or more authentication processes of the identified at least two eligible authentication processes based on the estimated profitability and account pu

Abstract: A method for providing an assured currency exchange rate includes: storing, in an account database, an account profile, wherein the account profile includes data related to a payment account including at least an account identifier, a conversion rule, and a period of time; receiving, by a receiving device, an authorization request for a payment transaction, wherein the authorization request includes at least the account identifier, a transaction amount in a first currency, and a transaction time and/or date that is within the period of time; calculating, by a processing device, a new transaction amount in a second currency based on application of the conversion rule to the transaction amount in the first currency; updating, by the processing device, the authorization request to include the calculated new transaction amount in the second currency; and forwarding, by a transmitting device, the updated authorization request.

Abstract: The present invention provides a recombinant plasmid adapted for transformation of a host microorganism, the plasmid comprising a plasmid vector into which a polydeoxyribonucleotide segment that codes for ammonia monooxygenase and hydroxylamine oxidoreductase has been inserted, wherein the resulting transformant exhibits at least 50% of the overall level of ammonia monooxygenase and hydroxylamine oxidoreductase activity of the donor. Also provided are an isolated polydeoxyribonucleotide segment that encodes ammonia monooxygenase and hydroxylamine oxidoreductase, and a transformant containing the ammonia monooxygenase and hydroxylamine oxidoreductase gene segments.

Abstract: This invention relates to processes for the microbial production of peptide oligomers, to polypeptide products resulting from application of any of these processes, and to microbes for use in such production. Another aspect of this invention relates to processes for genetically engineering such microbes and to plasmid vectors for use in such engineering.
