Person recognition systems based on individual biometric traits like fingerprint, face, and iris have been the focus of this book thus far. Most of these biometric systems can be labeled as unibiometric systems because they rely on a single biometric source for recognition. Any piece of evidence that can be independently used to recognize a person is called a source of biometric information. Unibiometric systems have some limitations.What if the biometric source becomes unreliable due to sensor or software malfunction, poor quality of specific biometric trait of the user, or deliberate manipulation? Furthermore, high-security applications and large-scale civilian identification systems place stringent accuracy requirements that cannot be met by existing unibiometric systems.
