Web1 de fev. de 2024 · Guo et al. [16] proposed a HTSIS to share a secret image among a set of participants with different levels of hierarchy. Their scheme is basically an adaptation of Tassa ′ s hierarchical secret sharing scheme [20]. The secret can be reconstructed if and only if the shadows (involved in decoding) satisfy a sequence of threshold for each level. WebHierarchical secret sharing schemes are known for the way the secret is shared among a group of participants that is partitioned into levels. We examine these schemes in terms of how easily they delete a secret after it is distributed or namely for cases where the reliability of data deletion depends on deletion of the indispensable participants' share.
