  We shall show that the abstract and formal rules which govern the quantum
kinematic and dynamics can be derived from a law of change of the information
content or the degree of uncertainty that the system has a certain
configuration in a microscopic time scale, which is singled out uniquely, up to
a free parameter, by imposing the condition of Macroscopic Classicality and the
principle of Locality. Unlike standard quantum mechanics, however, the system
always has a definite configuration all the time as in classical mechanics,
following a continuous trajectory fluctuating randomly in time.
