Friendly and Progressive Visual Secret Sharing with Lossless Reconstruction
Heri Prasetyo, Jing-Ming Guo, Chih‐Hsien Hsia · 2019
This paper presents a new simple and efficient technique for secret sharing. This technique inherits the effectiveness of Progressive Visual Secret Sharing (PVSS), in which the quality of recovered secret image is improved if more shared images are stacked together using the eXclusive-OR (XOR) operation. The proposed method also extends the usability of PVSS approach into the Friendly Visual Secret Sharing (PVSS). The content of shared image is converted into more friendly appearances rather than in the noise-like shared image. The proposed method offers promising result for grayscale and color image. It also produces recovered secret image in the lossless condition. The proposed method can be regarded as a good candidate for secret sharing.
