There is a growing trend in the financial world for criminals to focus their efforts on the telephone banking channel. For this reason, many financial institutions have begun to fortify their security system by incorporating biometric identification. Just as there are no two identical faces, fingerprints or irises in the world, so there aren't two human voices alike. And since phones already come equipped with the appropriate capture device for voice input, voice biometrics are set to provide the ease of implementation and low costs required for mass-market deployments. When a customer rings the bank, his/her true identity can automatically be verified through a series of sophisticated algorithms that are used to compare his voice with a corresponding reference voiceprint.
