In a (k n) visual cryptography scheme (VCS) a secret image is encoded into n shadow images that are distributed to n participants Any k participants can reveal the secret image by stacking their shadow images and less than k participants have no information about the secret image In this paper we consider the case when the secret image is more than one and this is a so-called multi-secret VCS (MVCS) The previous works on MVCS are all the simple 2-out-of-2 cases In this paper we discuss a general (k n)-MVCS for any k and n This paper has three main contributions (1) our scheme is the first general (k n)-MVCS which can be applied on any k and n (2) we give the f
