Biometrics deals with identification of individuals based on their biological or behavioral characteristics. Biometrics has lately been receiving attention in popular media. it is widely believed that biometrics will become a significant component of the identification technology as (i) the prices of biometrics sensors continue to fall, (ii) the underlying technology becomes more mature, and (i...

Throughout the last 40 years, the essence of automated identification of users has remained the same. In this article, a new class of biometrics is proposed that is founded on processing biosignals, as opposed to images. After a brief introduction on biometrics, biosignals are discussed, including their advantages, disadvantages, and guidelines for obtaining them. This new class of biometrics i...

This paper is a survey on biometrics and forensics, especially on the techniques and applications of face recognition in forensics. This paper describes the differences and connections between biometrics and forensics, and bridges each other by formulating the conditions when biometrics can be applied in forensics. Under these conditions, face recognition, as a non-intrusive and non-contact bio...

Because biometrics-based authentication offers several advantages over other authentication methods, there has been a significant surge in the use of biometrics for user authentication in recent years. It is important that such biometrics-based authentication systems be designed to withstand attacks when employed in security-critical applications, especially in unattended remote applications su...

Multi-biometrics is an exciting and interesting research topic. It is used to recognizing individuals for security purposes; to increase security levels. The recent research trends toward next biometrics generation in real-time applications. Also, integration of biometrics solves some of unimodal system limitations. However, design and evaluation of such systems raises many issues and trade-off...

After a short introduction to biometrics w.r.t. IT security, we derive conclusions on how biometrics should be put to use and how not at all. In particular, we show how to handle security problems of biometrics and how to handle security and privacy problems caused by biometrics in an appropriate way. The main conclusion is that biometrics should be used between human being and his/her personal...

From the INS to ATM’s, both the public and private sectors are making extensive use of biometrics for human recognition. As this technology becomes more economically viable and technically perfected, and thus more commonplace, the field of biometrics will spark legal and policy concerns. Critics inevitably compare biometrics to Big Brother and the loss of individual privacy. The probiometric lo...

Different types of biometrics are currently available in the market, and are widely used in various security applications. Biometrics can be classified into two categories, “physiological biometrics” and “behavioral biometrics”. Physiological biometrics identify the user based on physiological characteristics, such as fingerprints and eye retina/iris scanning, whereas behavioral biometrics depe...
