recommendations! Published in 2017 at "Multimedia Tools and Applications"

DOI: 10.1007/s11042-017-5065-3

Abstract: Encrypted image-based reversible data hiding methods have recently been introduced to conduct research on data encryption. In these methods, an image provider generates encrypted images that are supplied to a data sender. The data sender… read more here.

DOI: 10.1063/5.0130538

Abstract: Multiscale versions of weighted (and non-weighted) permutation entropy for two dimensions are considered in order to compare and analyze the results when different experiments are conducted. We propose the application of these measures to analyze… read more here.

recommendations! Published in 2022 at "IEEE Signal Processing Letters"

DOI: 10.1109/lsp.2022.3143038

Abstract: Data hiding in encrypted images (DHEI) embeds data in the cipher state, which not only protects the confidentiality of the cover image content, but also hides the existence of the secret information, and has a… read more here.
