PURPOSE To investigate, through ultrasound biomicroscopy images, the presence of plateau iris configuration in eyes with narrow-angle from patients with open-angle glaucoma and in eyes with previous acute primary angle-closure and compare the biometric features of eyes with plateau iris configuration with those of normal eyes. METHODS Ultrasound biomicroscopic images from 196 patients with op...

This paper deals with a biometric solution for authentication on mobile devices. Among the possible biometric modalities, speaker recognition seems the most natural choice for a mobile phone. This work lies in the continuation of our previous work [1], where we evaluated a candidate algorithm in terms of performance and time processing. The proposed solution is implemented here as an Android ap...

Testing of biometric systems requires the consideration of aspects beyond technical and statistical parameters. Especially for testing biometric techniques based on behavior, human factors like intention and forgery strength need to be considered. In this paper, a test tool to support skilled forgeries by test subjects is presented for handwriting verification systems. The software tool has bee...

We present a biometric authentication algorithm with 3 possible outputs: accept the claimed identity, reject the claimed identity, and no answer. The algorithm is based on the model of non–stationary random processes and transformations of realizations of the processes to q-ary vectors whose components are uniformly distributed over the set {0, . . . , q − 1}, where q is fixed. An application o...

Purpose: Recent studies have documented a link between axial myopia and ciliary muscle morphology; yet, the variation in biometric characteristics of the emmetropic ciliary muscle are not fully known. Ciliary muscle morphology, including symmetry, was investigated between both eyes of emmetropic participants and correlated to ocular biometric parameters. Methods: Anterior segment optical cohere...

The performance evaluation of biometric systems is a crucial step when designing and evaluating such systems. The evaluation process uses the Equal Error Rate (EER) metric proposed by the International Organization for Standardization (ISO/IEC). The EER metric is a powerful metric which allows easily comparing and evaluating biometric systems. However, the computation time of the EER is, most o...

Biometrics based authentication system provides better security solutions than conventional systems. But, some biological parameters that are used as biometric do not provide the guarantee of the presence and aliveness of the person as voice can be copied through microphone, finger print can be collect on silicon surface and iris can be copied on contact lances. ECG doesn’t have these problems ...
