Abstract
A system is disclosed for the automatic detection of fraudulent activity on a transaction network, for which each transaction over the network has an associated identifier. In one embodiment, the system includes voice comparison means for comparing a first sampled voice of a user of a first transaction with a subsequently sampled voice of a user of a subsequent transaction having an identical identifier to that of the first transaction. Control means in the form of a voice-based fraud detection engine is provided for determining, from said comparison, a profile of user usage that is representative of a total number of different users of the associated identifier. In a preferred embodiment, the system also includes voice sampling means for sampling a voice of the user of the first transaction to generate a first voice sample.
