  This paper investigates the information loss paradox in the WKB/tunneling
picture of Hawking radiation. In the tunneling picture one can obtain the
tunneling amplitude to all orders in $\hbar$. However all terms beyond the
lowest, semi-classical term involve unknown constants. Despite this we find
that one can still arrive at interesting restrictions on Hawking radiation to
all orders in $\hbar$: (i) Taking into account only quantum corrections the
spectrum remains thermal to all orders. Thus quantum corrections by themselves
will not resolve the information loss paradox. (ii) The first quantum
correction give a temperature for the radiation which goes to zero as the mass
of the black hole goes to zero. Including higher order corrections changes this
nice result of the first order corrections. (iii) Finally we show that by
taking both quantum corrections and back reaction into account it is possible
under specific conditions to solve the information paradox by having the black
hole evaporate completely with the information carried away by the correlations
of the outgoing radiation.
