Though there have been many research works carried out on the grayscale secret image
sharing schemes, there is not sufficient research work available on the field of color secret …

In the literature of secret sharing, the property of essential secret sharing scheme ensures
that no set of participants, missing at least one essential participant, should be able to get …

With an advancement in biomedical applications, many images are communicated over the
public networks. Therefore, these medical images are prone to various security threats …

The transition of visual secret sharing from a black & white secret image to a color image is
not straight-forward. There are several models of color superposition principle. In this paper …

Abstract Chinese Remainder Theorem based secret image sharing schemes provide an
efficient way to store secret image files securely in a distributed manner. Two basic …

The research on color Visual Cryptographic Scheme (VCS) is much more difficult than that of
the black and white VCS. This is essentially because of the fact that in color VCS, the rule for …

The current paper offers a lossless (k, n)-threshold scheme with reduced shadow size using
the algebraic properties of the polynomial ring Z _ 251 x Z 251 x over the field Z _ 251 Z 251 …

Abstract In Visual Cryptographic Scheme (VCS) shares of the secret image look like random,
whereas in Extended Visual Cryptographic Scheme (EVCS) the shares look like meaningful …

In the modern digital era, long-term protection of digital data, stored in a server, is essential,
especially when it is in the format of medical images like electronic health records, MRI …

In this paper, we consider the robustness of a special type of secret sharing scheme known
as visual cryptographic scheme in which the secret reconstruction is done visually without …
