- Abstract
The existing approaches of block based recovery of progressive secret sharing paradigm have support for limited k value in (k, n). Sian et al.'s as well Quan et al.'s block based visual secret sharing scheme has limited bound; works for a limited k value of k , n threshold scheme. A novel threshold based (any value of k a n d n ) block recovery in progressive secret sharing has been introduced and analyzed in this paper. Scheme achieves higher value of threshold than the schemes proposed by Sian et al.'s as well Quan et al.'s. The scheme discusses the sharing ability in progressive block based secret sharing up to any general number of thresholds. The contrast of the recovered block wise secret is reasonably good and the scheme allows for perfect security using at least k numbers of participants before revealing any of the blocks of secret image. The work in this paper offering a reference point for developing solutions needed in the area of secure image sharing techniques.
