Visual Cryptography Scheme (VCS) is a kind of secret sharing scheme which allows the encoding of a secret image into shares that distributed to n participants. The beauty of such scheme is that a set of qualified participants is able to recover the secret image without any cryptographic knowledge and computation devices. Extended Visual Cryptography Scheme (EVCS) is a kind of VCS which consists of meaningful shares (compared to the random shares of traditional VCS). In this paper, the authors propose a construction of EVCS which is realized by embedding random shares into meaningful covering shares, and they call it the embedded Extended Visual Cryptography Scheme (embedded EVCS).
