Special Issue Information

Dear Colleague,

With the rapid development of information and communication technologies (ICTs; e.g., 5G, mobile edge computing, smart mobile edge devices, and social networks), the generated massive big datasets lead to an exceptional increase in research activities in big data. At present, many big data analytics tasks request the reform of mobile users’ personal data protection legal framework in the context of the adoption of a General Data Protection Regulation (GDPR), which exhibits the importance of privacy and security issues in big data research. Big data security has become an indispensable requirement in our lives—not only for personal privacy, but also for exploring and the potential symmetry to assure analytics efficiency and security performance. Advanced associated technologies central to and at the periphery of this research domain include blockchain, mobile cloud/edge computing, artificial intelligence, social networks, smart healthcare, smart city, Industry 4.0, etc. For example, blockchain has the capability to enhance predictive analytics because it verifies data validity, preventing false information with trustness from being included in big data analyses. The big data security market was valued at USD 17.38 billion in 2019, and is projected to reach USD 57.29 billion by 2027, growing at a CAGR of 17.35% from 2020 to 2027. This Special Issue aims to present cutting-edge research addressing privacy and security protection challenges in big data analytics. Original and unpublished high-quality research results are solicited to explore various challenging topics which include, but are not limited to:

The intersection of blockchain and the symmetry applied in privacy and security issues of big data analytics;
Symmetry applied in the privacy and security of personal health records big data;
Security/privacy/trust and symmetry applied in big data issues in mobile cloud/edge computing;
Security/privacy/trust and symmetry applied in big data issues in social networks, smart healthcare, smart cities, Industry 4.0, etc.;
Security/privacy/trust-enabled big data mining methods for symmetry applied in big data analytics;
Adversarial attack and defense in symmetry-applied AI-enabled big data systems;
Symmetry applied in case study experience reports on big data security, privacy, and trust;
Symmetry applied in private information retrieval over typical big data platforms;
Symmetry applied in data-centric security and data classification;
Symmetry applied in cost and usability models related security issues in mobile and social network big data;
Symmetry applied in privacy-preserving machine-learning methods for big data analytics;
Symmetry applied in security and privacy policies for big data analytics;
Symmetry applied in secure big data management.

Abstract

Malware is one of the most frequent cyberattacks, with its prevalence growing daily across the network. Malware traffic is always asymmetrical compared to benign traffic, which is always symmetrical. Fortunately, there are many artificial intelligence techniques that can be used to detect malware and distinguish it from normal activities. However, the problem of dealing with large and high-dimensional data has not been addressed enough. In this paper, a high-performance malware detection system using deep learning and feature selection methodologies is introduced. Two different malware datasets are used to detect malware and differentiate it from benign activities. The datasets are preprocessed, and then correlation-based feature selection is applied to produce different feature-selected datasets. The dense and LSTM-based deep learning models are then trained using these different versions of feature-selected datasets. The trained models are then evaluated using many performance metrics (accuracy, precision, recall, and F1-score). The results indicate that some feature-selected scenarios preserve almost the same original dataset performance. The different nature of the used datasets shows different levels of performance changes. For the first dataset, the feature reduction ratios range from 18.18% to 42.42%, with performance degradation of 0.07% to 5.84%, respectively. The second dataset reduction rate is between 81.77% and 93.5%, with performance degradation of 3.79% and 9.44%, respectively. Full article

Abstract

The emergence of blockchain technology makes it possible to address disparate distributed system security concerns in formerly ridiculous practices. A key factor of this ability is the decentralization of the symmetrically distributed ledgers of blockchain. Such decentralization has replaced several security functionalities of centralized authority with the use of cryptographic systems. That is, public or asymmetric cryptography is the key part of what makes blockchain technology possible. Recently, the blockchain experience introduces the chance for the healthcare field to implement these knowhows in their electronic records. This adoption supports retaining and sharing the symmetrical patient records with the appropriate alliance of hospitals and healthcare providers in a secure decentralized system, using asymmetric cryptography like hashing, digitally signed transactions, and public key infrastructure. These include specialized applications for drug tracking, applications for observing patients, or Electronic Health Records (EHR). Therefore, it is essential to notice that the principled awareness of the healthcare professionals is the leading point of the right perception ethics. In this work, we provide a thorough review of the issues and applications of utilizing blockchain in the healthcare and medical fields emphasizing the particular challenges and aspects. The study adopted a systematic review of secondary literature in answering the research question. Specifically, this paper aims to investigate how blockchain technology can be applied to improve the overall performance of the healthcare sector and to explore the various challenges and concerns of the application of blockchain in the healthcare system.
