Embedding Data and Sharing Original Image in Two Stego Images Using Sudoku

, 2012
[[abstract]]Secret information can be protected by using information hiding techniques. In this paper, we propose a novel reversible information hiding scheme by using Sudoku. The proposed scheme embeds two secret digits in the base-9 numeral system into

A study of optimally essential secret image sharing scheme

, 2017
碩士本論文提出一個兩層式結構的(t, s, k, n)關鍵秘密影像分享門檻技術，當中有s個關鍵分享影像和n-s個非關鍵分享影像，且還原回秘密影像時，需收集t個關鍵分享影像和k個分享影像，其中分享影像包括關鍵分享影像和非關鍵分享影像。在此技術中定義一個參數m，m=1時，將獲得最小的總分享影像的影像大小及關鍵分享影像的影像大小接近於非關鍵分享影像的影像大小；m=t時，將獲得關鍵分享影像的影像大小和非關鍵分享影像的影像大小為2倍關係，並且能凸顯關鍵分享影像的重要性，此外，本論文克服前人Chen的方法[3 ...
