CRYPTOGRAPHY

Abstract

Traditional cryptography requires shared information for authentication, typically in the form of a secret token or password. These password authentication schemes are widely used in today's wired society, but they have a number of fundamental flaws, the most important of which is their inability to discriminate between legitimate users and hackers using stolen credentials. Biometric solutions address these issues by using bodily traits to distinguish legitimate users from imposters. These systems do, however, have a special set of weaknesses. The study of cryptographic techniques for safeguarding biometric systems is known as biocryptography, and it sits at the nexus of biometrics and conventional cryptography. This study investigates cutting-edge biocryptographical techniques to develop systems that are accurate and resistant to intrusions.
