Abstract: A system for identifying complete account identifiers from partial account identifiers is provided. The system includes an account identification computing device including at least one processor and a memory device in communication with the at least one processor. The processor is configured to receive transaction data including unique merchant identifiers, build a merchant table using the transaction data, and receive a list including partial account identifiers. The processor is further configured to determine, for each unique merchant identifier, a number of candidate account identifiers and calculate at least one metric based on the number of candidate account identifiers. The processor is further configured to identify a source unique merchant identifier and match at least one candidate account identifier to a complete account identifier by matching one of the partial account identifiers to the at least one candidate account identifier.

Abstract: A method and system for detecting fraudulent network events in a payment card network by incorporating breach velocities into fraud scoring models are provided. A potential compromise event is detected, and payment cards that transacted at a compromised entity associated with the potential compromise event are identified. Subsequent transaction activity for the payment cards is reviewed, and a data structure for the payment cards are generated. The data structure sorts subsequent transaction activity into fraud score range stripes. The data structure is parsed over a plurality of time periods, and at least one cumulative metric is calculated for each of the time periods in each fraud score range stripe. A plurality of ratio striping values are determined, and a set of feature inputs is generated using the ratio striping values. The feature inputs are applied to a scoring model used to score future real-time transactions initiated using the payment cards.

Abstract: A method of producing pulverized coal as fuel for pulverized-coal pilot burners of pulverized-coal annular burners or of systems thereof in a power plant having auxiliary steam generators. The raw coal undergoes or is subjected to a pulverizing-drying, and the pulverized coal which is produced is separated off in a separating system and is supplied either directly or after temporary storage by means of a suitable transporting system to the pilot burners. The thermal drying energy for the pulverizing system is taken from the flue gases of the auxiliary steam generator. The foregoing method can also be utilized for pulverized-coal burners or systems thereof.
