Abstract
A computerized system that processes a fraud score for a financial transaction in connection with an account is computed from retrieved data to indicate a probability of the account being in a compromised condition. A self-similarity score is computed if the computed fraud score is above a predetermined threshold to indicate similarity of the received transaction to other transactions of the account in the set of prior transactions. A suggested action to authorize or decline the transaction is determined based on the computed fraud score and the computed self-similarity score.
