Abstract

With the increasing of data and sensible information stored in smartphones, control the access to this devices is essential in order to mitigate risks. In this sense, a variety of authentication mechanisms has been explored, as the use of passwords and gestures. However, users tend to set weak password combinations or gestures that are easy to reproduce. This fact has been stimulating the research for continuous authentication methods, based on the user's interaction, which also run in background. The purpose of this paper is a new continuous authenticating method based on acoustic signature that is produced by the user-smartphone's interaction.
