The information loss paradox for Schwarzschild black holes is examined, using
the ADS/CFT correspondence extended to the M6(4,2) bulk. It is found that
the only option compatible with the preservation of the quantum unitarity is
when a regular remnant region of the black hole survives to the black hole
evaporation process, where information can be stored and eventually retrieved.Comment: 5 pages Latex file, no figures. A honourable mention in the 2005 GRF
