Descripción
Due to the intensive use of mobile phones for di®erent purposes, these devices usually contain con¯dential information which must not be accessed by another person apart from the owner of the device. Furthermore, the new generation phones commonly incorporate an accelerometer which may be used to capture the acceleration signals produced as a result of owner's gait. Nowadays, gait identi¯cation in basis of acceleration signals is being considered as a new biometric technique which allows blocking the device when another person is carrying it. Although distance based approaches as Euclidean distance or dynamic time warping have been applied to solve this identi¯cation problem, they show di±culties when dealing with gaits at di®erent speeds. For this reason, in this paper, a method to extract an average template from instances of the gait at di®erent velocities is presented. This method has been tested with the gait signals of 34 subjects while walking at di®erent motion speeds (slow, normal and fast) and it has shown to improve the performance of Euclidean distance and classical dynamic time warping.
