US Patent 9330416 Visualization of fraud patterns

An improved technique involves identifying other transactions for investigation from entries in a database that involve a particular actor involved in a known fraudulent transaction. From a transaction log listing transactions, a server generates a database of transaction entries which identify transactions from the transaction log, each transaction entry (i) describing an activity and (ii) identifying a set of actors involved in that activity. Based on a known fraudulent transaction involving a particular actor, the server finds a set of transaction entries from the database which involve the particular actor. From the found set of transaction entries, the server identifies other transactions for investigation.
