<p>A method and system for implementing a call-back verification procedure for a commercial transaction which is presented to the consumer (18) as part of the commercial transaction, i.e., at the website of the merchant, or alternatively, the consumer (18) may be redirected from the merchant's website to a different website where the call-back verification procedure is initiated. The consumer (18) is required to input their call-back telephone number, along with payment information, such as, for example, a credit card number. A voice-print provided by the user is subsequently verified (20) and stored in memory (22), at a server (12). The server (12) telephones (19) the consumer (18) and requests a voice response which is compared to the stored voice-print. This voice response is used to verify that the consumer (18) authorized the commercial transaction.</p> |
