The safeguarding of digitized data against unwanted access and modification has become
an issue of utmost importance as a direct result of the rapid development of network …

In previous (k, n) secret image sharing scheme, the threshold k is decided by dealer
according to the security requirement, and this threshold value is fixed without considering …

As a well-known secret image sharing scheme, Thien-and-Lin's scheme generates shadow
images of reduced size, which is beneficial for storage, transmission, and processing …

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 …

Abstract Recently, Chen and Wu propose a (n, n) multi secret image sharing (MSIS) scheme
that shares n secret images into n shared images. These n shared images can be together …

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 …

Secret image sharing is a method to decompose a secret image into shadow images
(shadows) so that only qualified subset of shadows can be used to reconstruct the secret …

Abstract Essential Secret Image Sharing (ESIS) is a method to decompose a secret image
into two groups of shares, where one group is essential and the other group is non …

Recently, Li et al. proposed a (t, s, k, n) essential secret image sharing (ESIS) scheme with
different importance of shadows, which has s essential shadow images and n− s non …

All secret image sharing (SIS) schemes are based on a finite field, on which the generation
and reconstruction can be accomplished correctly. To achieve distortionless secret images …
