It is a challenging work to design a blind color image watermarking scheme for protecting
copyright, which is different from the existing schemes used binary image or grayscale …

A novel four-image encryption scheme based on the quaternion Fresnel transforms (QFST),
computer generated hologram and the two-dimensional (2D) Logistic-adjusted-Sine map …

The aim of information hiding is to embed the secret message in a normal cover media such
as image, video, voice or text, and then the secret message is transmitted through the …

In this paper, we propose a new fragile watermarking scheme with high-quality recovery
capability based on overlapping embedding strategy. The block-wise mechanism for …

Most of the existing image steganographic approaches embed the secret information
imperceptibly into a cover image by slightly modifying its content. However, the modification …

This paper investigates the decision-theoretic rough sets involved multiple decision-makers
with linguistic evaluation information for the uncertainty and risk under the framework of …

The traditional information hiding methods embed the secret information by modifying the
carrier, which will inevitably leave traces of modification on the carrier. In this way, it is hard …

Due to the limited length and freely constructed sentence structures, it is a difficult
classification task for short text classification. In this paper, a short text classification …

A very common way of image tampering is the copy-move attack. When creating a copy-
move forgery, it is often necessary to add or remove important objects from an image. To …

The education plays a more and more important role in disseminating knowledge because
of the explosive growth of knowledge. As one kind of carrier delivering knowledge, image …
