The potential of hand shape and hand texture-based biometry is investigated and algorithms are developed. Feature extraction stage is preceded by meticulous registration of the deformable shape of the hand. Alternative features addressing hand shape and hand texture are compared. Independent component analysis features prove to be the best performing in the identification and verification tasks...

In terms of user authentication, biometric systems offer numerous advantages in terms of convenience. However, they also suffer from disadvantages in some applications, for example, in the area of privacy protection. To enhance security and privacy in biometrics, cancelable biometrics have been introduced. In this paper, we propose cancelable biometrics for face recognition using a PCA method a...

Reducing the bandwidth consumption on the network traffic has been a major concern over the past many years. With the advent of biometrics over the Internet, this issue will become more apparent as the performance of such system relies heavily on the network performance, reliability and security. This paper presents investigations conducted into the transmission of data over the network for the...

⎯ One of the aims of cancelable biometrics is to protect privacy. In order to protect privacy, cancelable biometrics are preferably to be non-invertible such that no information can be revealed from the cancelable biometrics template, which is stored in databases for personal identification/verification. One way to achieve the non-invertibility is through the use of non-invertible transforms. R...

Many security applications require accurate identification of people, and research has shown that iris biometrics can be a powerful identification tool. However, in order for iris biometrics to be used on larger populations, error rates in the iris biometrics algorithms must be as low as possible. Furthermore, these algorithms need to be tested in a number of different environments and configur...

This essay contributes an extended view on user information inferred by personal devices to motivate applications of biometrics beyond user identification. We unfold a new design space in two parts: First, we take inspiration from the shared focus on individuality in both biometrics and Belk’s Extended Self (ES, [1, 2]). ES describes that people use (digital) objects to define and reflect on th...

Insider misuse is a key threat to organizations. Recent research has focused upon the information itself – either through its protection or approaches to detect the leakage. This paper seeks a different approach through the application of transparent biometrics to provide a robust approach to the identification of the individuals who are misusing systems and information. Transparent biometrics ...

This paper gives an insight into biometrics used for speaker recognition. Three different biometrics are presented, based on: acoustic, geometric lip, and holistic facial features. Experiments are carried out using a corpus of the DAVID audio-visual database. Recognition accuracy is found to be similar in the 2 domains. The geometric visual feature is based on a method of signature coding of th...

Systems that use unimodal biometrics tend to have less accuracy, variations that are due to intra class, restricted degree of freedom, non-universality, error rates that are not acceptable, etc. Based on these reasons, in the near past, most of the researchers have been concentrating on multimodal biometrics. Multimodal biometrics integrates various types of biometrics which outperform unimodal...

Applications of biometrics system are increasingly day by day as these methods provide more reliable and accurate way of identification and verification. Psychological studies indicate that people have a small but statistically significant ability to recognize the gait of individuals that they know. Gait biometrics is one of the recent biometrics systems which works on the shape and gesture of ...
