Adaptive algorithms applied to accelerometer biometrics in a data stream context
(Ios Press, 2017)
The use of smartphone devices has increased over the last years, as illustrated by the growth in smartphone sales. These devices are currently used for several services, such as bank account access, social networks and ...
Enhanced template update: Application to keystroke dynamics
(Elsevier Advanced Technology, 2016)
With the increasing number of activities being performed using computers, there is an ever growing need for advanced authentication mechanisms like biometrics. One efficient and low cost biometric modality is keystroke ...
Ensemble of adaptive algorithms for keystroke dynamics
(Universidade Federal do Rio Grande do Norte – UFRNSociedade Brasileira de Computação – SBCNatal, 2015-11)
Biometric systems have been applied to improve the security of several computational systems. These systems analyse physiological or behavioural features obtained from the users in order to perform authentication. Biometric ...
Adaptive positive selection for keystroke dynamics
(SpringerDordrecht, 2015-12)
Current technologies provide state of the art services but, at the same time, increase data exposure, mainly due to Internet-based applications. In view of this scenario, improved authentication mechanisms are needed. ...

(Universidade de São Paulo - USPUniversidade Federal de São Carlos - UFSCarCentro de Robótica de São Carlos - CROBSociedade Brasileira de Computação - SBCSociedade Brasileira de Automática - SBASão Carlos, 2014-10)
Nowadays, many services are available from mobile devices, like smartphones. A growing number of people are using these devices to access bank accounts, social networks and to store personal information. However, common ...
Evaluation of denoising algorithms for footsteps sound classification in noisy environments
(2021)
Identifying a person using footsteps sounds is part
of the recent research in developing biometrics, systems designed
to identify an individual in a group using body measurements.
The sound of footsteps has a short ...
Outliers in biometrics : an a-contrario approach
(UR. FING, 2017)
This thesis addresses the problems of biometrics : how a persons identity could be determined or validated by using some physical or behavioral characteristic. Biometry is one of the main research topics in the field of ...
