Biometric based unique ID generation and one to one verification for security documents

Abstract

Security documents like certificates, land revenue documents, etc., have only the individual's name, address, and in some cases a photo as means of personal identification. This makes criminal impersonation an easy task. This paper proposes a method for creating a unique ID based on the core point of the fingerprint of an individual. The minutia features of the fingerprint are extracted with the core point as the reference. The numerical value thus generated is used to create the unique ID in the form of a QR code and this is printed in the security documents. There are current technologies to convert a fingerprint to barcode but the method proposed in this paper is more suitable for use in security documents.
