IDENTIFICATION AND MANAGEMENT OF FRAUDULENT CREDIT/DEBIT CARD PURCHASES AT MERCHANT ECOMMERCE SITES

摘要

Transaction processing of online transactions (121) at merchant sites (102) determines the likelihood that such transactions are fraudulent, accounting for unreliable fields of a transaction order, which fields do not reliably identify a purchaser (127). A scoring server (114) using statistical model use multiple profiles, along with weights to indicate the degree to which the profiles identify the purchaser of the transaction (129).
