No biometric is an island.

In the high-tech futuristic world of biometrics, no technology can stand alone.

In "Biometrics Futures," an article published in the April edition of Computers & Security, Robin L. Sherman compared biometric technologies and concluded "...that no biometric is likely to become dominant in the marketplace, since all those available have limitations that compromise the system solutions possible.

"As levels of cost come down," Sherman continued, "it might also be desirable in certain applications to use two biometrics in combination."

In the accompanying table, Sherman compares physiological techniques - such as faceprints, fingerprints, hand geometry, nonretinal and retinal blood vessel analysis - and behavioral techniques - such as keystroke dynamics, signature dynamics, and voiceprints - on the basis of performance, speed, cost, user acceptance, and integration potential.

Sherman concluded that voice-related biometrics hold the most promise. "Once speaker-dependent, continuous speech recognition technology has stabilized," he noted "it can be combined with other artificial intelligence techniques to provide interactive systems that appear to have intelligence."

Even though there has been promise of visionary applications, the article forecasted that widespread acceptance of biometrics is still at least 10 years away.
