The present invention relates to a computer implemented method to detect threats in a payment network using a threat detection algorithm by limiting the growth of a data tree, for use with a threat detection algorithm. The method comprises, receiving (1003) transaction data relating to a first transaction, and retrieving (1001) a data tree comprising a first node connected to a second node representing a second transaction, where the source account of the first transaction is the same as the destination account of the second transaction. The method further comprises determining (1005) a difference in time between the time of the second transaction and the time of the first transaction and determining (1007) a total number of accounts that have made a transaction with the source account of the first transaction. If the difference between the time of the second transaction and the time of the first transaction is less than a first predetermined length of time, and the total number of accounts to have made a transaction with the source account of the first transaction is less than a predetermined number of accounts, the data tree is updated (1009) to comprise a third node connected to the second node, the third node representing the destination account of the first transaction, and is inputted (1011) into a threat detection algorithm, to thereby detect threats in a payment network using the threat detection algorithm.

The method can include predicting speech based on the predicted phonemes.

An edge module (300) and corresponding methods are provided. One method includes receiving, by the edge module connected to a device (19A, 19B), a Modbus packet from a management system (20). The packet comprises a block write command to a command buffer and a block read command to a response buffer, wherein the buffers are associated with contiguous sets of registers of the edge module. The edge module interprets the request based on command buffer data, determining associated registers of the device to perform an action. The edge module generates and sends a second Modbus packet comprising a command to the determined registers for the device to perform the action. The edge module writes data into the response buffer based on device performance, to be read by the management system.
