A smart privacy preserving framework for industrial IoT using hybrid meta-heuristic algorithm

Abstract

Industrial Internet of Things (IIoT) seeks more attention in attaining enormous opportunities in the field of Industry 4.0. But there exist severe challenges related to data privacy and security when processing the automatic and practical data collection and monitoring over industrial applications in IIoT. Traditional user authentication strategies in IIoT are affected by single factor authentication, which leads to poor adaptability along with the increasing users count and different user categories. For addressing such issue, this paper aims to implement the privacy preservation model in IIoT using the advancements of artificial intelligent techniques. The two major stages of the designed system are the sanitization and restoration of IIoT data. Data sanitization hides the sensitive information in IIoT for preventing it from leakage of information. Moreover, the designed sanitization procedure performs the optimal key generation by a new Grasshopper–Black Hole Optimization (G–BHO) algorithm. A multi-objective function involving the parameters like degree of modification, hiding rate, correlation coefficient between the actual data and restored data, and information preservation rate was derived and utilized for generating optimal key. The simulation result establishes the dominance of the proposed model over other state-of the-art models in terms of various performance metrics. In respect of privacy preservation, the proposed G–BHO algorithm has achieved 1%, 15.2%, 12.6%, and 1% enhanced result than JA, GWO, GOA, and BHO, respectively.

Challenges and Limitation Analysis of an IoT-Dependent System for Deployment in Smart Healthcare Using Communication Standards Features

“…Such mechanics can be applied in a wide range of industries, enabling the collection of large amounts of data. As a pilot technology of the Fourth Industrial Revolution [69] IoT mechanics have already been fruitful in many areas, such as smart stationing [70], agricultural fidelity [71] and management of water usage [72]. Remote health monitoring can be implemented for patients at home instead of in a hospital, minimizing pressure on hospital assets such as beds and doctors.…”

An Electrical Impedance Imaging System Towards Edge Intelligence for Non-Destructive Testing of Concrete

“…By using the EIT imaging method, it is possible to image the internal part of objects, such as concrete structures or the inside of the human body. With the advent remote structural health monitoring and non-destructive testing impedance, imaging is considered as an efficient method [18,19] with enough security in complex environment [19] . The output of the EIT system is an image of the electrical conductivity distribution inside the target object.…”

A New Privacy-Preserving Data Publishing Algorithm Utilizing Connectivity-Based Outlier Factor and Mondrian Techniques

“…It is vital to share the processed data with other individuals, institutions, and organizations in order to generate a high level of value from it. However, because this data may contain various personal data that can directly or indirectly identify the individual, sharing such data without adequate protection will result in significant problems, such as attackers revealing the identities of data owners over the shared dataset [2,3]. On the other hand, if data privacy safeguards are overly stringent, data utility will suffer.…”
