Correlations between the modulation of the observed radiation flux and the changes in the polarization degree and angle are predicted by the orbiting spot model for flares from accreting black holes. We find that the geometric shape of the emission region plays a significant role in the amplitudes and profiles of the model lightcurves. In particular, the emission regions of spiral shape can be distinguished from the simpler geometry of a small orbiting spot. We discuss the relevance of this model for the observed flares from the supermassive black hole in the Galactic center. Despite the fact that the hot spot model represents a phenomelogical approach to the flare origin, its has a great value in constraining the model geometry and determining the possible scenario for the flare rapid emergence and the subsequent decay. The KY code allows us to simulate the lightcurves for a wide range of parameters. The energy dependence of the changing degree and angle of polarization should allow us to discriminate between the cases of a rotating and a non-rotating black hole.
