Protection of Patient Identity and Privacy using Vascular Biometrics

Biometric systems are being used in hospitals to streamline patient registration and identification, as an effective measure to protect patient privacy and prevent identity theft. Many Hospitals and Healthcare institutions are turning towards Vascular Biometrics which complements the biometric recognition with hygiene and improved accuracy. In this paper, a multimodal hand vein system and a multibiometric fingerprint-hand vein biometric system are proposed. The multimodal hand vein system is a non-invasive, contactless and fast system, which uses two different feature sets extracted from each hand vein image. The multibiometric system captures both the fingerprint as well as the hand vein of the patient and hence offers even more improved performance though the speed and the cost of the system as well as the hygiene are reduced. We have used the Euclidean classifier to calculate the performance rates namely the False Rejection Rate (FRR) and False Acceptance Rate (FAR) of the Vein System and the Fingerprint-Vein System. We have performed this analysis using a volunteer crew of 74 persons. The FRR and FAR were 0.46% and 0.7% in the former case and 0% and 0.01% in the latter case respectively. The multimodal or the multibiometric system could be used based of the Hospital’s requirements.
