Gait is a biometric trait that can allow user authentication, though it is classified as a “soft” one due to a
certain lack in permanence and to sensibility to specific conditions. The earliest research relies on computer
vision, especially applied in video surveillance. More recently, the spread of wearable sensors, especially
those embedded in mobile devices, has spurred a different research line. In fact, they are able to capture the
dynamics of the walking pattern through simpler one-dimensional signals. This capture modality can avoid
