Finally,we see Hawking’a much hyped paper on the solution of black hole information puzzle come out.As expected, no technical details can be found in his paper, he leaves one of his students to carry out this impossible mission.

What we can find in his paper (hep-th/0507171)is a rough idea: he uses anti-de Sitter space for the purpose of regularizing infinities encountered
in the Euclidean path integral. So he can build his picture upon some work by Maldacena (hep-th/0106112) where Maldacena shows that certian correlations in an eternal Euclidean anti-de Sitter black hole background exponentially decay.

So no technicality is offered for resolving information in the end of the black hole evaporation, Stephen Hawking burned an encyclopedia and gave us the ashes.
