We characterize even measures μ=wdx+μs on the real line R with finite entropy integral [Formula presented] in terms of 2×2 Hamiltonians generated by μ in the sense of the inverse spectral theory. As a corollary, we obtain criterion for spectral measure of Krein string to have converging logarithmic integral.
