Our algorithm was tested on 60 volunteer adults, with age ranging from early 20s to late 50s. The most important results are False Acceptance Rate (FAR) equal to 0.0% and False Rejection Rate (FRR) at the level of 1.19%, with Equal Error Rate (EER) 0.59% during authorization (referred to as verification mode since algorithm verifies the claimed identity), when using a template derived from three images. In identification mode we got results FAR=0.0%, FRR=1.19% and ERR=0.59%. We achieved Identification Rate (IR) equal to 100.0% when taking only subjects from the database in identification mode. The subjects were not limited regarding the position of their hand on the scanner, nor were hand injuries and jewelry a disqualifying factor. Moreover, we describe the performance and time needed in a real-life experiments, showing that the algorithm may be used by people without technical background at low cost and is adequate for systems that require medium to high level of security.
