Biometric signatures, or biometrics, are used to identify individuals by measuring certain unique physical and behavioral characteristics. Individuals must be identified to allow or prohibit access to secure areas—or to enable them to use personal digital devices such as, computer, personal digital assistant (PDA), or mobile phone. Virtually all biometric methods are implemented using the follo...

Biometrics identification methods have proved to be very efficient, more natural and easy for users than traditional methods of human identification. Biometrics methods truly identify humans, not keys and cards they posses or passwords they should remember. Ear on the other hand, has a more uniform distribution of color, so almost all information is conserved when converting the original image ...

Biometrics authentication o,ers many advantages over conventional authentication systems that rely on possessions or special knowledge. With conventional technology, often the mere possession of an employee ID card is proof of ID, while a password potentially can be used by large groups of colleagues for long times without change. The fact that biometrics authentication is non-repudiable (hard ...

The word biometry or its derivative, biometrics, depicts the need for close interdisciplinary research among big data systems, mathematics, and statistical sciences. Reports headed with biometrics are constantly increasing. Below, information provided by databases evidences expansion evolution from original main biological topics to new areas.

W E ARE pleased to present 14 papers in this special issue devoted to recent advances in biometric systems. A total of 78 papers were submitted for consideration for the special issue. Those that appear in this special issue result from a careful review process and consideration of timing for the special issue. Other papers, which were originally submitted for consideration for the special issu...

Nowadays, the use of biometric characteristics (e.g., palmprints, irises, fingerprints) is incrementing for individual recognition and many applications of biometrics are already available. Biometrics recognition has many advantages over the traditionally used methods (e.g., password, smart card), because biometric characteristics cannot be shared or forgotten, as it is inherently associated wi...

Personal identification and authentication is difficulty in all the systems. Shared secrets like Personal Identification Numbers or Passwords and key devices such as Smart Cards are not presently sufficient in few situations. These traditional tokens based systems may be easily stolen or lost. Biometrics is the only way of improving the capability to recognize the persons according to the physi...

Biometrics based authentication provides various advantages over other authentication methods, it has replaced the password based authentication and token based authentication. Biometrics plays a major role in Automated Teller Machine (ATM) system, E-Commerce, Online banking, Passports. The growth in electronic transactions has been increased tremendously; there is a greater demand for fast and...

In this paper, a new multi-factor authenticated key exchange scheme, which combines with biometrics, password and the smart card, is proposed. Compared with the previous schemes, this scheme has higher security in remote authentication and preserves privacy of biometrics , and most of the previous schemes rely on the smart card to verify biometrics. The advantage of these approaches is that the...

Around the globe, governments are pursuing policies that depend on information technology (IT). The United Kingdom’s National Identity Scheme was a government proposal for a national identity system, based on biometrics. These proposals for biometrics provide us with an opportunity to explore the diverse and shifting discourses that accompany the attempted diffusion of a controversial IT innova...
