An item on policeone.com, by Thomas Bush III, Strategic Advisor for BIO-key International, caught my attention. In the article, “How to buy police biometrics products,” he presents guidelines, or, what he calls the “Four E’s,” for selecting biometrics systems. Although Mr. Bush focuses on fingerprint biometrics, I believe his criteria are spot-on for voice biometrics as well. Here they are:
• Effectiveness: “The basic measure of any authentication solution is accuracy. However, biometrics accuracy often comes with a price - in the form of “false negatives” or improper rejection of individuals who should have been successfully authenticated. While this is often attributed to “user error,” the potential end result in user frustration and time lost in re-authenticating must still be part of the measurement of overall effectiveness.”
• Ease of deployment and use: “No technology can be effective unless, and until, it’s operational and in regular use. A “bleeding edge” biometrics solution, even if it’s potentially more effective, may never get out of pilot, and one that users find confusing or cumbersome may not even make it that far. The solution should be easy to deploy and maintain and shouldn’t require significant changes to business processes.”
• Enterprise-wide capability: “While an organization may deploy an authentication solution to meet a single need today, it makes sense early in the selection process to look at where and how the use of biometrics may be expanded to meet future needs. This can save money and simplify administration.”
• Economic considerations: “Keeping costs under control is important – even when budgets aren’t under the strain they are today. …While the software is usually proprietary, a strong ongoing maintenance and support agreement can help ensure that the software can be enhanced on an ongoing basis, extending the life cycle of the solution, even as technology changes.”
