Abstract:
1. A method of detecting whether a current user is or is not the same as an intended user of a device or of identifying a current user of a device, the method comprising: detecting interactions or activities of the user with or through the device; after having detected an activity, analyzing the activity to decide, based on recorded data of a previously detected activity, whether the detected activity belongs to a predetermined model of user behavior; in response to determining that the activity belongs to the predetermined model, storing data of the activity in a buffer associated with said predetermined model; analyzing the data stored in the buffer to determine whether sufficient data are stored in the buffer or whether the buffer is full; in response to determining that there are sufficient data stored in the buffer or the buffer is full, using the data stored in the buffer for comparing to data in a behavior profile of a user; and in response to determining that the data stored in the buffer does not sufficiently agree with said data in the behavior profile, signal or indicate this result to cause an alarm to be generated or use the result for an evaluation whether the current user is or is not the same as the intended user or use the result for identifying the current user, and otherwise to discard the data stored in said buffer; wherein the data recorded for a detected user activity always includes a timestamp of the detected activity when the detected activity occurred.
