Biometric Authentication System Using Dorsal Hand Vein Pattern

Biometric authentication is a method of identifying individuals for security purpose based on the distinctive physiological characteristics of a person for verification and authentication. The use of biometrics provides a more definitive security layer in identification authentication of users in many fields. Biometric authentications can be implemented using finger print, iris, skin and voice and so on. Vein pattern is an extensive group of blood vessels underneath an individual's skin. These vein patterns are considered to be distinct and special to each individual and they are invariant in proportion. Taking in considerations the drawbacks of other biometric recognition methods, hand vein biometric is selected, as it is efficacious, guaranteed, secure and highly reliable for identification, authentication of individuals. So as to enable biometric authentication, cost effective scanning devices are brought into use. The device includes the use of No IR camera which is used for acquisition of vein image and a matrix of NIR LEDs which is helps to capture only the veins in the camera. The system is designed using Raspberry Pi at its heart and also makes use of Open CV, a library in Python which is used for image processing.
