Special Issue Information

Dear Colleagues,

Data generation and sharing have shown a drastic increase in the ongoing decade due to recent technologies such as the Internet of Things (IoT) and Big Data technologies. The reason behind this is the growing sources of data due to huge research and smart revolution (smart grids, cities, devices, credit card transactions, social media activities, or Electronic Health Records (EHR), etc.).  The collected data may contain private information (e.g., name, contact number, social security number) about the data owners. In today’s modern society, the leakage of such private information is a major concern. Recently in 2019, it has been reported that 41 million healthcare records were breached. Moreover, another report indicates that the U.S. healthcare department lost $6.2 billion annually due to private information leakage in EHR. However, sharing user data is also very important to government agencies and private stakeholders for latest research and policy-making. Therefore, the purpose of Privacy-Preserving Data Publishing (PPDP) methods is to keep the privacy of an individual before publishing the data using anonymization techniques.

In this regard, due to the ongoing demand for IoT and Big Data technologies, the PPDP has become an active research area.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Applied Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Advancements in sensor-enabled devices led to the emergence of resource trading models for smart communities, such as the smart marketplace (SMP). Most of the proposed SMP architectures are based on blockchain technology, which has a public ledger to achieve transparency. Consequently, safeguarding the participant’s anonymity, untraceability, and transactional data privacy during trading becomes a challenging task. Most of the existing solutions to achieve anonymity are based on multiple account mapping, which is prone to identity-based attacks, and cryptographic techniques are used to achieve transactional data privacy, which often has a high computational overhead. In this work, we propose a lightweight privacy-enabled message exchange mechanism to accomplish our privacy goals in a blockchain-based SMP. Evaluation of the scheme was conducted to measure its resilience toward safeguarding participants’ anonymity, untraceability, and transactional data privacy during trading cycles. Statistical game theory-based security analysis and simulation based performance analysis of the proposed scheme showed that it achieved the desired privacy goals with a low computational overhead compared with existing state-of-the-art schemes.
