We present a new member of the biometrics family-i.e., nose pores-which uses particularly interesting properties of nose pores as a basis for noninvasive biometric assessment. The pore distribution on the nose is stable and easily inspected. More important, nose pore distribution features are distinguishable between different persons. Thus, these features can be used for personal identification. However, little work has been done on nose pores as a biometric identifier. We have developed an end-to-end recognition system based on nose pore features. We also made use of a database of nose pore images obtained over a long period to examine the performance of nose pores as a biometric identifier. This research showed that the nose pore is a promising candidate for biometric identification and deserves further research. The experimental results based on the unique nose pores database demonstrated that nose pores can give an 88.07% correct recognition rate for biometric identification, which showed this biometric identifier's feasibility and effectiveness.
