An Improved Essential Secret Image Sharing Scheme with Smaller Shadow Size

Li, Peng; Liu, Zuquan - In: International Journal of Digital Crime and Forensics (IJDCF) 10 (2018) 3, pp. 78-94

This article describes how in conventional (k, n) secret image sharing (SIS), any k or more shadows can be collaborated together to reveal the secret image. Usually, all shadows have the same importance. Recently, an essential (t, s, k, n) secret image sharing (ESIS) with different importance of...
