Visual cryptography (VC) is a variant form of secret sharing. In general threshold setting, the
k-out-of-n VC allows that, in a set of n participants, any k can recover and reconstruct the …

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 …

Long-term protection of multimedia contents is a complex task, especially when the video
has critical elements. It demands sophisticated technology to ensure confidentiality. In this …

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 …

Komargodski et al. introduced Evolving Secret Sharing which allows an impartial participant,
called dealer, to share a secret among unbounded number of participants over any given …

Abstract OR-based Visual Cryptographic Schemes (OVCS) suffer from poor visual quality of
the reconstructed image. XOR-based visual secret sharing (XVCS) can be thought of as an …

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 …

We put forward a construction of visual cryptographic scheme (VCS) to address the
scenario, where there are several levels of importance of shadows. Traditional (k, n) …

傳統的加密法需要大量且複雜的運算才能將秘密訊息予以解密, 然而視覺密碼學有別於其他加密
機制, 其利用秘密分享的概念, 將秘密訊息藏至數張分享影像內, 解密的動作不需要透過電腦的 …
