Interest on palmprint biometrics has experimented a strong growth in the last decades due to its useful characteristics as uniqueness, permanence, reliability, user-friendliness, acceptability, non-intrusiveness, and low cost of the acquisition devices, which make it attractive for civil and commercial applications. Accordingly, a wide research has been developed in this field. Nevertheless, there...
In this work, the Curvelet transform is proposed as a fairly new feature extraction method for palmprint recognition. Particularly, a multiscale analysis has been performed at four levels, assessing and combining the features extracted at each level in order to find those which better represent the palmprint. Feature matching has been conducted by means of Euclidean distance and Support Vector Machines...
This work presents a configurable multibiometricsystem oriented to mobile devices which combines face, handand in-air signature biometrics to provide three different levelsof security. The number of traits involved in the authenticationincreases with the security strength, allowing the balance betweencomfort and accuracy according to the security requirements ofthe final application. In addition,...
Comfort and security perception are two key factorsto provide an adequate biometric solution. This article presentsthe results of an online survey about these characteristics in fourdifferent biometric modes implemented in mobile phones withwidespread sensors. Additionally, it presents the main concernsthat the use of these biometric modes generates in people, whichprovides a roadmap of additional...
