As a classical secret sharing technique,(k, n) threshold secret image sharing mainly contains
the shadow generation phase and the image reconstruction phase. The sensitive secret …

In scalable (k, n) secret image sharing schemes, original secret image can be partially
recovered from any set of k shadows gradually, the entire image can be recovered from n …

In the traditional secret image sharing schemes, the shadow images are generated by
embedding the secret data into the cover image such that a sufficient number of shadow …

Multi-level secret image sharing is a scheme combining hierarchical shadows with
progressive reconstruction. But in previous schemes, the generated shadows are divided …

In traditional secret image sharing schemes, the participants have the same status, and
shadow images are of approximately equal importance, which cannot satisfy some special …

Secret Image Sharing (SIS) plays an important role in the field of information security. At
present, from the perspective of image restoration, SIS schemes are roughly divided into two …

ABSTRACT A (k, n)‐scalable secret image sharing (SSIS) scheme shares a secret image
into n independent shadow images. This (k, n)‐SSIS scheme can simultaneously provide …

Secret image sharing (SIS) is a technique to decompose a secret image into multiple
shadows distributed to the corresponding participants. Only qualified subsets of the …

This paper presents an improved (t, s, k, n)-scalable essential secret image sharing based
on Lagrange interpolation. In the proposed scheme, an image is shared to n participants in …

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 …
