In digital world, the security of data is one of the most important issues. Biometric cryptosystems provide great convenience and security by combining biometrics and cryptography. The aim of this paper is to provide a good standpoint into the state-of-the-art and current research directions of crypto systems using biometric key, including theory and applications.

Introduction

Towards the digital transformation age, information barter over the Internet and the storing of data on open networks has been widely increased. This also increases the importance of cryptography in computer science. Cryptography is designed to provide confidentiality and authenticity of a message. Generally; during the communication, encryption and decryption operations are performed for securing information through cryptographic key. Providing secure of this key is major concern, so key chose is essential. One should care that the keys are not estimated easily. At this point biometric cryptosystems provide great convenience and security by combining biometrics and cryptography. Cryptographic keys will be produced dynamically thanks to biometrics. What the thing makes it so popular is biometric data cannot be stolen or lost. A variety of biometric traits has been used in many applications such as fingerprint, palm print, hand geometry, face, iris, vein, retina, and odour. Depending on the requirements of used application, each biometric has independently own advantages and disadvantages.
