New secure QIM-based information hiding algorithms [PDF]
Компьютерная оптика, 2018 The paper proposes two information hiding algorithms for multimedia based on Quantization Index Modulation (QIM): IM-QIM and SIM-QIM. They are designed to prevent a statistical attack which is able to restore a secret key using the correlation between ...

On the Bayes risk in information-hiding protocols [PDF]
Journal of Computer Security, 2008 Randomized protocols for hiding private information can be regarded as noisy channels in the information-theoretic sense, and the inference of the concealed information can be regarded as a hypothesis-testing problem. We consider the Bayesian approach to the problem, and investigate the probability of error associated to the MAP (maximum a posteriori ...

Image encryption algorithm based on reversible information hiding and physical chaos in images
Results in Physics, 2023 This article proposes a reversible information hiding algorithm based on chaos and histogram translation in ciphertext images to address the shortcomings of traditional algorithms such as separation of encryption and information hiding processes, small ...

A coverless steganography method based on generative adversarial network
EURASIP Journal on Image and Video Processing, 2020 The traditional information hiding is realized by embedding the secret information into the multimedia, but it will inevitably leave the modification mark in the carrier. This paper proposed a new method of coverless information hiding.

SIHNet: A safe image hiding method with less information leaking
IET Image ProcessingImage hiding is a task that hides secret images into cover images. The purposes of image hiding are to ensure the secret images are invisible to the human and the secret images can be recovered.

Information Hiding Techniques: A Tutorial Review [PDF]
arXiv, 2008 The purpose of this tutorial is to present an overview of various information hiding techniques. A brief history of steganography is provided along with techniques that were used to hide information. Text, image and audio based information hiding techniques are discussed. This paper also provides a basic introduction to digital watermarking.

International Journal of Adaptive Control and Signal Processing, EarlyView.Summary Data‐driven forecasting of ship motions in waves is investigated through feedforward and recurrent neural networks as well as dynamic mode decomposition. The goal is to predict future ship motion variables based on past data collected on the field, using equation‐free approaches.

Large Capacity Data Hiding in Binary Image black and white mixed regions [PDF]
Information hiding technology utilizes the insensitivity of human sensory organs to redundant data, hiding confidential information in the redundant data of these public digital media, and then transmitting it. The carrier media after hiding secret information only displays its own characteristics, which can ensure the transmission of confidential ...
