‎In this paper‎, ‎we consider an inverse boundary value problem for two-dimensional heat equation in an annular domain‎. ‎This problem consists of determining the temperature on the interior boundary curve from the Cauchy data (boundary temperature and heat flux) on the exterior boundary curve‎. ‎To this end‎, ‎the boundary integral equation method is used‎. ‎Since the resulting system of linear algebraic equations is ill-posed‎, ‎the Tikhonov first-order regularization procedure is employed to obtain a stable solution‎. ‎Determination of regularization parameter is based on L-curve technique‎. ‎Some numerical examples for the feasibility of the proposed method are presented‎.
