One of the possible ways of formulation of an information loss paradox refers to an entanglement of the two particles created in a vicinity of an event horizon. Evolution of the entangled particles and an interaction with their own environments should lead to a decay of the entanglement. However obvious, such a perspective appears to be too naive in this case.
Using the generalized uncertainty principle, we calculate the entropy of the charged dilaton-axion black hole for both asymptotically flat and non-flat cases by counting degrees of freedom near the horizon. The divergence of density of states and free energy appearing in the thin film brick-wall model is removed without any cutoff. The entropy proportional to the horizon area is derived from the contribution of the vicinity of the horizon.
