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 … secret image itself using reversible watermarking algorithm; then, watermarked image is divided into $n$ sub image. Secondly … secret image through a series of decryption operations and extraction of reversible watermarking. The proposed scheme can …

Reversible Watermarking in Digital Image Using PVO and RDWT

Gao, Tiegang; Gao, Lin; Zhao, Jie; Liu, Yonglei - In: International Journal of Digital Crime and Forensics (IJDCF) 10 (2018) 2, pp. 40-55

This article proposed a reversible digital image watermarking scheme using PVO and Redundant Discrete Wavelet Transform (RDWT). The PVO was introduce to the proposed scheme to enhance the embedding capacity. By embedding the watermark in the RDWT coefficients, the proposed scheme exploited the...
