A study of secure Boolean-based multiple secret image sharing scheme
, 2015 碩士 本論文提出一個以(n, n)為門檻值的多重影像秘密分享技術，在此門檻值下可以分享n張秘密影像，並透過本文所提出的演算法產生相同數量的n張分享影像，還原時必須蒐集所有分享影像後才能將秘密影像依序還原。本論文所提出的演算法以XOR布林函式運算為主，故而能有極佳的執行效能。此外，以布林運算為基礎的分享方法，需要使用亂數影像將秘密影像打亂，本論文在分享及還原時，提出亂數影像生成函式，因此在相同數量的分享影像下，可以分享更多數量的秘密影像，也不必耗費額外空間紀錄亂數影像。 相較其他學者所提出的分享方法，
