Improving visual quality of reversible data hiding by twice sorting
In most literatures on reversible data hiding (RDH), the visual quality of marked images is only assessed by PSNR, and the smoothness-priority-based sorting technique is efficient for improving PSNR. However, ...

Optimal structural similarity constraint for reversible data hiding
Until now, most reversible data hiding techniques have been evaluated by peak signal-to-noise ratio(PSNR), which based on mean squared error(MSE). Unfortunately, MSE turns out to be an extremely poor measure w...

A novel compressive sensing-based framework for image compression-encryption with S-box
In this paper, we find that compressive sensing (CS) with the chaotic measurement matrix has a strong sensitivity to plaintext. Because of the quantification executed after CS, however, the plaintext sensitivi...

(k, n) threshold secret image sharing scheme based on Chinese remainder theorem with authenticability
In the traditional secret image sharing (SIS) scheme, the secret image is divided into several noise-like shares, which lack authentication and may attract the attention of malicious users. Therefore, the auth...
