Abstract(in English)	The security condition of visual secret sharing schemes for q plural images (VSSS-q-PI) is considered in [9]. However, the condition is insufficient because some informations of the other secret images leak out from decrypted images even if the definition of VSSS-q-PI shown in [9] is satisfied. Hence, we give the new perfect definition of the security condition, and we propose a construction method which satisfies the new definition of the VSSS-q-PI. The proposed method is an extension of the known methods shown in [3][8][9].
