  • Towards Breaking DNN-based Audio Steganalysis with GAN   Order a copy of this article
    by Wang Jie, Wang Rangding, Dong Li, Yan Diqun, Zhang Xueyuan, Lin Yuzhen 
    Abstract: Recently, deep neural network (DNN) has significantly boosted the performance of audio steganalysis. Accordingly, most of the traditional steganography cannot resist such DNN-based steganalysis. In this work, we attempt to break a given DNN-based audio steganalysis method with a prespecified steganography. To achieve this goal, we propose to employ a generative adversarial network (GAN) to generate an enhanced cover audio firstly, which can be regarded as more suitable for steganography. Then, the secret message is embedded into the enhanced cover audio with the traditional steganography, instead of into the original cover audio. The experimental results demonstrate that our generated enhanced cover audio could effectively aid traditional steganography to break the advanced DNN-based audio steganalysis.

  • Collaborative Variational Factorization Machine For Recommender System   Order a copy of this article
    by Jiwei Qin, HongLin Dai 
    Abstract: At present, the recommendation systems are confronting the huge challenge of data sparsity and high complexity of algorithm. Like the traditional collaborative filtering recommendation methods, they are difficult to adapt to the data sparse environment, resulting in low prediction accuracy. To address the aforementioned issues, this paper presents a novel Factorization Machine based on Collaborative filtering framework called Collaborative variational Factorization Machine (CVFM) that considers the user-user relations with the interaction data for Recommender systems. First, the user-item explicit ratings are used to build the user-user relationship by the similarity calculation. Next, we develop a variational Factorization Machine with a linear process to exploit the inherent relationship of latent variables from interaction information. The experimental results on three different datasets show that the presented CVFM is superior to other popular methods in prediction accuracy, at the same time, maintain the stability of our algorithm with dealing with sparse data.

    by Tidiane SYLLA, Mohamed Aymeb Chalouf, Krief Francine, Karim Samake 
    Abstract: Internet of Things applications encompass home-automation, health, transportation, etc. The main objective of these applications is to improve user's daily lives. However, security and privacy threats and the lack of adapted security mechanisms could significantly reduce their development and slow down their adoption. Several researches have been conducted in order to find solutions for securing the IoT systems and to reduce, even eliminate risks for user’s privacy. One of the proposed solutions is context-aware security, which enable to consider relevant contextual information while implementing security mechanisms. In this paper, we will conduct a survey of the context-aware security solutions that have been proposed for smart city IoT applications. These applications have a great impact on citizen's life. For each solution, we will provide critical analysis in terms of context-aware management, security services and privacy mechanisms. Then, we will identify the different research directions for better context-aware security in these applications.

    Abstract: The growing technological development in the field of information and communication technology has evolved the futuristic concept of smart cities, wherein the objects, embedded with high speed processors and memory, would be intelligent in the sense that they are capable to communicate among each other and can take decision. The smart cities will ensure increased road safety, traffic mobility, sustain environment and economic development. To ensure these features smart vehicle becomes an integral component of the smart cities. The smart vehicles should be equipped with simultaneous intelligent sensing and communication technologies at the back end to enable for increased road safety, traffic mobility etc. This requires the joint operation of radar and communication without interference.

  • Network Dynamic Routing And Spectrum Allocation Algorithm Based On Blockchain Technology   Order a copy of this article
    by Jue Ma  
    Abstract: To overcome the problems of low resource utilization rate and high bandwidth blocking rate of traditional network dynamic routing and spectrum allocation, a network dynamic routing and spectrum allocation algorithm based on blockchain technology is proposed. In this algorithm, a hybrid integer linear model of network dynamic routing and spectrum allocation is constructed to minimize spectrum consumption and frequency. Based on the extended static heuristic algorithm of blockchain, the link with the largest load is selected to optimize the spectrum allocation, and the linear model and extended static heuristic algorithm are combined to update the frequency gap state of the link where the path is located, so as to achieve the purpose of dynamic routing and spectrum allocation of the network. The experimental results show that the spectrum utilization rate is as high as 99.66%, and the bandwidth blocking rate is as low as 0.
