Yampolskiy and Venu Govindaraju}, country = {}, institution = {}, abstract = {Functioning of a biometric system in large part depends on the performance of the similarity measure function. Frequently a generalized similarity distance measure function such as Euclidian distance or Mahalanobis distance is applied to the task of matching biometric feature vectors. However, often accuracy of a biometric system can be greatly improved by designing a customized matching algorithm optimized for a particular biometric application. In this paper we propose a tailored similarity measure function for behavioral biometric systems based on the expert knowledge of the feature level data in the domain. We compare performance of a proposed matching algorithm to that of other well known similarity distance functions and demonstrate its superiority with respect to the chosen domain.}, journal = {International Journal of Computer and Information Engineering}, volume = {2}, number = {12}, year = {2008}, pages = {4254 - 4259}, ee = {https://publications.waset.org/pdf/10863}, url = {https://publications.waset.org/vol/24}, bibsource = {https://publications.waset.org/}, issn = {eISSN: 1307-6892}, publisher = {World Academy of Science, Engineering and Technology}, index = {Open Science Index 24, 2008}, }
