  • Publication number: 20240428270
    Abstract: A system and method may detect rogue trading by detecting a subset of trades among a plurality of trades, where each trade in the subset does not meet a trade surveillance system threshold, and does meet a trade surveillance system threshold within a tolerance, and each trade falls within the same time period. A ratio of the subset of trades to the plurality of trades may be determined. If the ratio is above a threshold, it may be determined that the subset of trades corresponds to undesirable trading. Undesirable trading may be determined using an additional factor, based on a weighted average of, for each of a trade surveillance system threshold, the number of trades in the subset meeting the trade surveillance system threshold within a tolerance and not meeting a trade surveillance threshold, times a weight based on the position of the threshold in the trade surveillance system.

  • Patent number: 11875354
    Abstract: A system includes collecting serial numbers over a period of time, and constructing a matrix indicating which digits have been used at which positions. For a second period of time, the system collects a second group of serial numbers and, for each of these serial numbers, identifies a feature of the serial number by comparing it against the matrix, and automatically updates the matrix with the digits and digit positions of the serial number. The features are received into an artificial intelligence model as training data. Further, the system collects a third group of serial numbers and, for each serial number of the third group, identifies a feature of the serial number by comparing it against the matrix. These features are then received into the artificial intelligence model, which determines a risk score. The matrix is then updated with the digits and digit positions of the serial number.
