ABSTRACT
Palm vein recognition is a biometric identification method that integrates automated scientific applications to provide a way or means to identify a person by scanning a person’s palm vein in order to gain access.  Palm vein recognition technology is secure because the authentication data exists inside the body, it is very difficult to forge and it is highly accurate.

The palm vein feature extraction task is another challenging problem in the infrared hand palm recognition tasks. In this research two set of extraction techniques have been suggested to represent the veins grid attributes: (i) the Linear Discriminant Analysis and (ii) the Principal Component Analysis. Each extracted feature list is assembled as a feature vector used to distinguish between palms belonging to different persons.

The training and testing were performed on static printed images of palm vein for the database with the palm vein samples taken with different angular prints and that of normal print. The experiments were performed for the recognition system at cropped resolutions of 20x20, 30x30, 40x40, 50x50, and 60x60 pixels.  The system developed had average recognition performance accuracy of 96.86% and 90.45% for the LDA and PCA respectively. LDA performs better in terms of accuracy.

The best recognition performance was obtained when the LDA algorithm was used and this however shows why it is commonly used in authentication and verification process. The implemented system serves as an extendable foundation for future research.
