This paper proposes an alternative personal identification algorithm using finger crease pattern which is assumed to overcome the disadvantages of the existing biometrics system. We used a CED camera with LED lighting as the input device. The original images were treated by employing a lowpass and highpass Jilter to get the reinforced finger boundaries and finger crease patterns, thereby threshold is applied. We tracked the boundaries of the finger and extracted the Images of the index, middle, and ring finger, thereafter applied noise reduction operation. In the last step, we performed the verifications of a person by matching one dimensional profiles of finger crease patterns. This algorithm shows the possibility of an alternative biometrics identification system to the current ones. Lastly, the comparative evaluation on our system and the other algorithm is presented.
