On the other hand, a smartphone is equipped with sensors that can infer not only information about the context (e.g., location), but also about its owner. Since smartphones handle a huge amount o...

Multimodal authentication on smartphones: Combining iris and sensor recognition for a double check of user identity

Iris recognition on mobile devices is a challenging task, performing acquisition via the embedded sensors can introduce the sensor interoperability problem. Biometric systems developed so far are limited in their ability of comparing biometric data originated by different sensors because they operate under the assumption that the data to be compared are obtained using the same sensor. This prob...

A Survey on Behavioral Biometric Authentication on Smartphones

Recent research has shown the possibility of using smartphones’ sensors and accessories to extract some behavioral attributes such as touch dynamics, keystroke dynamics and gait recognition. These attributes are known as behavioral biometrics and could be used to verify or identify users implicitly and continuously on smartphones. The authentication systems that have been built based on these b...
