  We propose an algorithm for computing Stratonovich's value of information
(VoI) that can be regarded as an analogue of the distortion-rate function. We
construct an alternating optimization algorithm for VoI under a general
information leakage constraint and derive a convergence condition. Furthermore,
we discuss algorithms for computing VoI under specific information leakage
constraints, such as Shannon's mutual information (MI), $f$-leakage, Arimoto's
MI, Sibson's MI, and Csiszar's MI.
