(ISO: Geneva) -- From national identity cards to security checks for air travel, a wide variety of biometric applications may now benefit from improved reliability and performance, thanks to the technologies described in a new technical report.Biometrics uses personal characteristics to identify or verify the identity of users. The performance of a biometric system may be compromised if the biometric trait being sensed or measured is “noisy” (a fingerprint with a scar or a voice altered by a cold, for example), making the computed matching score not reliable. This problem can be addressed by installing multiple sensors that capture different biometric traits, known as biometric fusion or multimodal biometric systems.

Published by the International Organization for Standardization and the International Electrotechnical Commission, ISO/IEC TR 24722:2007—“Information technology-Biometrics—Multimodal and other multibiometric fusion,” offers technology solutions that may enable the fusion of multiple biometric indicators, such as face, fingerprint, and hand-geometry features, to improve multiple evidences of the same identity.
