Black Hole Information path described in new article

TL;DR

A paper appears to describe an event horizon mechanism for holding information and encoding it in the Hawking radiation.

I'm posting this in "Quantum Physics" although it is just as much "General Relativity".

A paper entitled "Quantum gravitational corrections to particle creation by black holes" was published in
Science Direct earlier this month.
It appears to provide an event horizon mechanism for holding information and encoding it in the Hawking radiation.
The abstract:

We calculate quantum gravitational corrections to the amplitude for the emission of a Hawking particle by a black hole. We show explicitly how the amplitudes depend on quantum corrections to the exterior metric (quantum hair). This reveals the mechanism by which information escapes the black hole. The quantum state of the black hole is reflected in the quantum state of the exterior metric, which in turn influences the emission of Hawking quanta.
