Random Grid and Reversible Watermarking-Based On Verifiable Secret Sharing for Outsourcing Images in Cloud

Gao, Tiegang; Gao, Hang; Hu, Mengting; Cheng, Renhong - In: International Journal of Digital Crime and Forensics (IJDCF) 10 (2018) 1, pp. 24-39

A novel random grid and reversible watermarking based verifiable secret sharing scheme for outsourcing image in cloud is proposed in the paper. In the proposed scheme, data owner firstly embeds the hash value of the secret image into the secret image itself using reversible watermarking...

A Novel Pixel Merging-Based Lossless Recovery Algorithm for Basic Matrix VSS

Zhang, Weizhe; Liu, Xin; Wang, Shen; Sang, Jianzhi - In: International Journal of Digital Crime and Forensics (IJDCF) 9 (2017) 3, pp. 1-10

Lossless recovery in visual secret share (VSS) is very meaningful. In this paper, a novel lossless recovery algorithm for the basic matrix VSS is proposed. The secret image is reconstructed losslessly by using simple exclusive XOR operation and merging pixel. The algorithm not only can apply to...

A Novel Visual Secret Sharing Scheme Based on QR Codes

Yan, Xuehu; Lu, Yuliang; Liu, Lintao; Wan, Song - In: International Journal of Digital Crime and Forensics (IJDCF) 9 (2017) 3, pp. 38-48

In this paper, a novel visual secret sharing (VSS) scheme using QR codes is investigated. The proposed visual secret … sharing scheme based on QR codes(VSSQR) can visually reveal secret image by stacking sufficient (shadow images) shares as well …
