- Enrolment time as a requirement for face recognition biometric systemsPublication . Sá, Vítor; Magalhães, Sérgio; Santos, HenriqueThe performance of a biometric system depends on the accuracy, the processing speed, the template size, and the time necessary for enrolment. This last factor is not much addressed in literature. In this work we collected information about the users' availability for enrolment in respect to face recognition biometrics. Were involved in testing 26 randomly chosen people. The results are presented globally, by sex, by age group and by previous experience in the use of the technology. We found that there is a generalized positive predisposition for enrolment that is expressed in some by the predisposition to try for many times and in others to try over a long time, and that it may be the youngest and the oldest the least available.
- Feasibility Study of a Multimodal Biometric Authentication Solution Based on Pointer Dynamics and Skin ConductivityPublication . Sá, Vítor J.; Tenreiro De Magalhaes, Sérgio; Santos, HenriqueDue to the constant need to improve authentication systems, since they are constantly emerging new forms of intrusion, based on the current state of knowledge, we intend to study the acceptance of a recognition system based on the combination of two non-physical methods of biometric authentication: pointer dynamics and skin conductivity. With this combination, firstly, it is improved what each can offer individually and, secondly, the problem of replicability present in physical biometric is minimized. We conducted a survey with a representative sample of the Portuguese population, whose construction method and obtained results are presented in this article. We also present an introductory explanation of the involved technologies.
- Enrollment time as a requirement for biometric hand recognition systemsPublication . Carvalho, João; Sá, Vítor J.; Magalhães, Sérgio Tenreiro de; Santos, HenriqueBiometric systems are increasingly being used as a means for authentication to provide system security in modern technologies. The performance of a biometric system depends on the accuracy, the processing speed, the template size, and the time necessary for enrollment. While much research has focused on the first three factors, enrollment time has not received as much attention. In this work, we present the findings of our research focused upon studying user’s behavior when enrolling in a biometric system. Specifically, we collected information about the user’s availability for enrollment in respect to the hand recognition systems (e.g., hand geometry, palm geometry or any other requiring positioning the hand on an optical scanner). A sample of 19 participants, chosen randomly apart their age, gender, profession and nationality, were used as test subjects in an experiment to study the patience of users enrolling in a biometric hand recognition system.
