Steganography Security: Principle and Practice
Yan Ke, Jia Liu, Min-qing Zhang +2
This paper focuses on several theoretical issues and principles in steganography security, and defines four security levels by analyzing the corresponding algorithm instances. In t…
The Reincarnation of Grille Cipher: A Generative Approach
Jia Liu, Yan Ke, Yu Lei +5
In order to keep the data secret, various techniques have been implemented to encrypt and decrypt the secret data. Cryptography is committed to the security of content, i.e. it can…
Generative Steganography by Sampling
Zhuo Zhang, Jia Liu, Yan Ke +4
In this paper, a novel data-driven information hiding scheme called generative steganography by sampling (GSS) is proposed. Unlike in traditional modification-based steganography,…
Generative Steganography with Kerckhoffs' Principle
Yan Ke, Minqing Zhang, Jia Liu +2
The distortion in steganography that usually comes from the modification or recoding on the cover image during the embedding process leaves the steganalyzer with possibility of dis…
Optimal Shape Design for Stokes Flow Via Minimax Differentiability
Z. M. Gao, Y. C. Ma, H. W. Zhuang
This paper is concerned with a shape sensitivity analysis of a viscous incompressible fluid driven by Stokes equations with nonhomogeneous boundary condition. The structure of shap…
Optimal Shape Design for the Time-dependent Navier--Stokes Flow
Zhiming Gao, Yichen Ma, Hongwei Zhuang
This paper is concerned with the problem of shape optimization of two-dimensional flows governed by the time-dependent Navier-Stokes equations. We derive the structures of shape gr…
