On the basis of vector magnetograms of two flaring active regions (ARs) we analyze the scaling behavior of the current helicity H_c in the photosphere. The signed measure so obtained possesses a well pronounced sign-singularity in the range of scales from more than 10(4) Km down to the resolution limit of observations. We found that during the flaring process there is a signature both of a reorganization of the current helicity in the photosphere and of a strong magnetic energy dissipation of the photospheric magnetic field.
