Most mobile phones and tablets support only two access control device states: locked and unlocked. We investigated how well allor-nothing device access control meets the need of users by interviewing 20 participants who had both a smartphone and tablet. We find all-or-nothing device access control to be a remarkably poor fit with users’ preferences. On both phones and tablets, participants want...

Selecting appropriate thresholds and fusion rules for a system involving multiple biometric verifiers requires knowledge of the match score statistics for each verifier. While this statistical information can often be measured from training data, that data may not be representative of the environment into which each verifier is deployed. To compensate for missing statistics, we present a techni...

Machine Readable travel documents have been rapidly put in place since 2004. The initial standard was made by the ICAO and it has been quickly followed by the Extended Access Control (EAC). In this paper we discuss about the evolution of these standards and more precisely on the evolution of EAC. We intend to give a realistic survey on these standards. We discuss about their problems, such as t...

We use grip pattern based biometrics as a secure side channel to achieve pre-authentication in a protocol that sets up a secure channel between two hand held devices. The protocol efficiently calculates a shared secret key from biometric data. The protocol is used in an application where grip pattern based biometrics is used to control access to police hand guns.

Although biometrics can be an useful component for access control, the security they procure is often overestimated, as if they were a magic tool whose simple use will automatically prevent each and every type of attack. Biometrics are not secure unless they are embedded in a strong cryptographic protocol, whose design pays special attention to their specificities. In particular, smart card rev...

We use grip pattern based biometrics as a location limited channel to achieve pre-authentication in a protocol that sets up a secure cannel between two handheld devices. The protocol efficiently calculates a shared secret key from biometric data using quantization and cryptanalysis. The protocol is used in an application where grip pattern based biometrics is used to control access to police ha...

The term Biometrics is becoming highly important in computer security world. The human physical characteristics like fingerprints, face, hand geometry, voice and iris are known as biometrics. These features are used to provide an authentication for computer based security systems. The existing computer security systems used at various places like banking, passport, credit cards, smart cards, PI...

BIOMETRICS are an important and widely used class of methods for identity verification and access control. Biometrics are attractive because they are inherent properties of an individual. They need not be remembered like passwords, and are not easily lost or forged like identifying documents. At the same time, biometrics are fundamentally noisy and irreplaceable. There are always slight variati...
