A security system is described, comprising a sensor module () which accommodates a laser sensor () working with self-mixing interference. The laser sensor () generates measurement data which are related to the velocity of an object such as the body of a human being and, optionally, the distance between the laser sensor () and the object. Dependent on the measurement data assembled by the laser sensor () and supplied to a control circuit () such as an airbag computer, the airbag computer activate security means such as an airbag ()in order to prevent injuries of the human body. Furthermore, a method of driving such a security system is described.
