The CAVE project focussed on the development and testing of speaker verification systems for use in telephone applications like calling-card or financial services. Although the telephone is a widely accepted and convenient medium for performing various sorts of transactions, there can be a major risk of fraud if access to the service is controlled only with a relatively insecure method such as the entry of a personal identification number (PIN) code using telephone keypresses.
In addition, the functionality and ease of use of current telephone banking services is restricted by the authentication problem, resulting in insecure or lengthy "log-in" procedures, and the deferment of some transactions until the account holder can be notified in writing. Speaker Verification, by which a telephone caller's identity claim (currently represented by the combination of an account number and PIN-code) can be augmented with information derived from the sound of the caller's voice, is a potential solution to these problems, and could allow for fast and secure authentication of callers.
