A Survey of Multibiometric Systems
Harbi AlMahafzah, Maen Zaid AlRwashdeh · International Journal of Computer Applications · 2012
Most biometric systems deployed in real-world applications are unimodal.Using unimodal biometric systems have to contend with a variety of problems such as: Noise in sensed data; Intra-class variations; Inter-class similarities; Nonuniversality; Spoof attacks.These problems have addressed by using multibiometric systems, which expected to be more reliable due to the presence of multiple, independent pieces of evidence.
