  The information paradox suggests that the black hole loses information when
it emits radiation. In this way, the spectrum of radiation corresponds to a
mixed (non-pure) quantum state even if the internal state generating the
black-hole is expected to be pure in essence. In this paper we propose an
argument solving this paradox by understanding the process of spontaneous
symmetry breaking when the black-hole selects one among the many possible
ground states, emitting then radiation as a consequence of it. Here the
particle operator number is the order parameter. This mechanism explains the
connection between the density matrix corresponding to the pure state
describing the black-hole state and the density matrix describing the spectrum
of radiation (mixed quantum state). From this perspective, we can recover the
black-hole information from the superposition principle applied to the
different possible order parameters (particle number operators).
