Basic biometric characteristics, modern systems & technologies of biometric authentication

Improving Computer Authentication Systems with Biometric Technologies

In this paper we describe that user authentication methods based on hash functions like MD5, NT / NTLM and SHA-1 can be easily compromised. We used methods that utilize cryptanalytic tables based on time memory tradeoff procedures (TMTO) and we analyzed certain limitations on this approach. We suggest improvements to this technique and additional concepts like parallelized creation and querying...

Privacy Protecting Biometric Authentication Systems Privacy Protecting Biometric Authentication Systems

Privacy Protecting Biometric Authentication Systems As biometrics gains popularity and proliferates into the daily life, there is an increased concern over the loss of privacy and potential misuse of biometric data held in central repositories. The major concerns are about i) the use of biometrics to track people, ii) non-revocability of biometrics (eg. if a fingerprint is compromised it can no...

Biometric Technologies for Online Student Authentication

In this work we present: i) an analysis of biometric technologies for online student authentication; ii) a case study on keystroke dynamics authentication applied to a real operational environment. Concisely, this work studies the biometric technologies and their advantages/disadvantages for online student authentication services. The analysis is made on the basis of three main pillars: perform...

Biometric Systems for User Authentication

Authenticating the identity of users is a critical issue in information security. Biometrics is known for recognizing users based on their physiological or behavioral traits as identifiers and these cannot be easily stolen unlike passwords or ID cards. Biometrics could be employed as the primary means for authentication, called user identification, as well as a complementary (secondary) method ...
