Biometric authentication has attracted attention because of its high security and convenience. However, biometric feature such as fingerprint can not be revoked like passwords. Thus once the biometric data of a user stored in the system has been compromised, it can not be used for authentication securely for his/her whole life long. To address this issue, an authentication scheme called cancela...

An appropriate combination of multiple biometric sensors increases the reliability of verification through biometrics. In this paper we propose an effective method of fusion of biometrics based on a dynamic selection of threshold point of fingerprint and iris biometrics towards identifier of an optimal set of rules for fusion. The effectiveness of the method has been established using several b...

The introduction of the electronic passport by governments around the world marks a major step in the use of biometrics. In fact, the electronic passport, or e-passport for short, combines the use of three important technologies for identification: biometrics, smartcards and radio frequency identification (RFID). Smartcards – increasingly often RFID-enabled – are already commonplace in our ever...

Biometrics, e.g., fingerprints, the iris, and face, have been widely used to authenticate individuals. However, most biometrics are not cancellable, i.e., once these traditional cloned or stolen, they cannot be replaced easily. Unlike biometrics, brain extremely difficult clone forge due natural randomness across different individuals, which makes them an ideal option for identity authenticatio...

Biometrics is an application area in which different biological traits of a person is taken as input for person identification or authentication. This is highly needed for security reasons. Unimodal biometrics is easy to implement as it uses only one trait or modality of a person but it has many drawbacks like spoofing, non-universality, etc. Multimodal biometrics uses more than one modality of...

This survey covers the historical development and current state of the art in image understanding for iris biometrics. Most research publications can be categorized as making their primary contribution to one of the four major modules in iris biometrics: image acquisition, iris segmentation, texture analysis and matching of texture representations. Other important research includes experimental...

Multibiometrics is the usage of more than one physiological or behavioral characteristic to identify an individual. Multibiometrics is advantageous over unibiometrics as it is resilience to spoofing and has low False Acceptance Rate (FAR). However Multibiometrics requires storage of multiple biometric templates for each user, which results in increased risk to user privacy and system security. ...

Biometrics are traditionally employed in user authentication and authorization mechanisms. The vast majority of research effort focuses on applications of biometrics in authentication, aiming to replace passwords as the access control mechanism for cryptographic keys in one way or another. However, the inherent variability in biometrics presents a readily available source of randomness, which, ...

Recently, bio-information has been playing an important role in modern user authentication schemes. In 2004, Lin and Lai proposed a flexible biometrics remote user authentication scheme. However, their scheme is vulnerable and cannot provide mutual authentication between user and remote system. Hence, Khan and Zhang improved the security of a flexible biometrics remote user authentication schem...

Biometrics are used for authentication. It isused to recognize a person based on their unique characteristics. Among several biometrics, Fingerprint is the most widely used and acceptable biometrics. Biometric system has several advantages over traditional methods. But it can be affected by several attacks. In this paper type 1 attack is discussed which is performed at the sensor level. Differe...
