The most common account based password used for authentication is textual passwords. But textual passwords are in risk to phishing attack, burette force attack, social engineering and shoulder surfing. Biometrics is used for human recognition which consists of authentication, verification and recognition. Biometric passwords are introduced as alternative techniques to textual passwords. Many biometric systems exist today by using fingerprint, face, iris, etc but risk to duplicating a fake (For e.g.: "Fingerprint-gummy finger"). Palm vein authentication is one of the modern biometric techniques, which employs the vein pattern in the human palm to verify the person.
