Biometric integrated systems uses physical features to check a person's identity and it is use to ensure much greater security than password and number systems. Biometric features such as the fingerprint or face can be stored in a credit card on microchip, for example. A single feature, however, sometimes fails to be exact enough for identification. Another big disadvantage of using only one feature is that the chosen feature is not always readable.
(DCS AG) which is Dialog Communication Systems developed BioID that is a multimodal identification system which uses three different features-face, voice, and lip movement for identifying people. With its three modalities, BioID achieves much greater precision and accuracy than single-feature systems. Even if one of the modality is somehow and anyhow disturbed-for example, if a noisy environment drowns out the voice-the either two modalities still lead to an accurate and precise identification. This article explains about the system functions, explaining about the data acquisition and preprocessing techniques for voice, facial, and lip imagery data. The article has also explained about the classification principles used for optical features and the sensor fusion options (the combinations of the three results-face, voice, lip movement-to obtain varying levels of security)
