Bio-Cryptographic systems enforce authenticity of cryptographic applications like data encryption and digital signatures. Instead of simple user passwords, biometrics, such as, fingerprint and handwritten signatures, are employed to access the cryptographic secret keys. The Fuzzy Vault scheme (FV) is massively employed to produce bio-cryptographic systems, as it absorbs variability in biometric...

Most existing computer and network systems authenticate a user only at the initial login session. This could be a critical security weakness, especially for high-security systems because it enables an impostor to access the system resources with the initial access permission. To address this security flaw, Continuous authentication of the user is necessary, to continuously monitors and authenti...

Biometric systems are used extensively for user access control in restricted secure environments. In this paper we are developing a low cost Palmprint biometric system with limited cheaper available resources. We are proposing an algorithm, which will obtain the necessary details from the image and user authentication will be performed accurately with help of templates stored in the database. T...

Mosaicking in biometrics is a topic of great interest among researchers these days, since it is an important step towards solving the problem of security of data. This paper presents design and implementation of Mosaicking algorithm. This technique is beneficial for providing authentic access as well as security to the biometric image template. We have designed an algorithm for fingerprint mosa...

Biometrics technology is rapidly progressing and offers attractive opportunities. In recent years, biometric authentication has grown in popularity as a means of personal identification in ATM authentication systems. The prominent biometric methods that may be used for authentication include fingerprint, palmprint, handprint, face recognition, speech recognition, dental and eye biometrics. In t...

Biometrics provides a new dimension of security to modern automated applications since each user will need to prove his identity when attempting an access. However, if a stored biometric template is compromised, then the conventional biometric recognition system becomes vulnerable to privacy invasion. This invasion is a permanent one because the biometric template is not replaceable. In this pa...

Current research often focuses on the design of new methods that extend the well-established role of biometrics in authentication and identification into key management and cryptography. Methods have been proposed that involve biometric-governed access to cryptographic keys, as well as methods that utilize biometric samples to derive keys for specialized encryption algorithms. The aim of this p...

This paper discusses the methods of biometrics recognition technology and applications that used as personal identifying factors. Biometric recognition refers to an automatic recognition of individuals based on a feature vector(s) derived from their physiological and/or behavioral characteristic. Technologies are being developed to verify or identify individuals on the basis of measurement of f...

Biometrics-based user authentication has several advantages over traditional password-based systems for standalone authentication applications, such as secure cellular phone access. This is also true for new authentication architectures known as crypto-biometric systems, where cryptography and biometrics are merged to achieve high security and user convenience at the same time. In this paper, w...
