In this paper, new high-capacity separable reversible data hiding in an encrypted halftoned
image is proposed. The proposed scheme used Hamming code to exploit embedding …

Data hiding is one of the most important techniques to achieve better data and
communication protection by hiding information into a media carrier. It provides a secure …

Data hiding and reversible data hiding research has primarily focused on grayscale and
color images, because binary and halftone images are prone to visual distortion caused by a …

In this paper, we carry out a performance analysis from a probabilistic perspective to
introduce the error diffusion-based halftone visual watermarking (EDHVW) methods' …

Efficiently transferring information, which is of major importance for almost all engineering
systems, requires a data representative appropriate to maintain the density and consistency …

This article proposes a blind discrete wavelet transform-discrete cosine transform (DWT-
DCT) composite watermarking scheme that is robust against print and scan distortions. First …

We present a new high capacity color barcode. The barcode we propose uses the cyan,
magenta, and yellow (C, M, Y) colorant separations available in color printers and enables …

The ubiquitous presence of surveillance cameras severely compromises the security of
private information (eg passwords) entered via a conventional keyboard interface in public …

In this paper, a halftoning-based watermarking method is presented. This method enables
high pixel-depth watermark embedding, while maintaining high image quality. This …

Visual encryption and show through watermarking are widely used techniques to hide secret
data in halftone images. The secret watermark can be quickly revealed when the halftone …
