Abstract
Smart cameras and image sensors are widely used in industrial processes, from the designing to the quality checking of the final product. Images generated by these sensors are at continuous risk of disclosure and privacy breach in the industrial Internet of Things (IIoT). Traditional solutions to secure sensitive data fade in IIoT environments because of the involvement of third parties. Blockchain technology is the modern-day solution for trust issues and eliminating or minimizing the role of the third party. In the context of the IIoT, we propose a permissioned private blockchain-based solution to secure the image while encrypting it. In this scheme, the cryptographic pixel values of an image are stored on the blockchain, ensuring the privacy and security of the image data. Based on the number of pixels change rate (NPCR), the unified averaged changed intensity (UACI), and information entropy analysis, we evaluate the strength of proposed image encryption algorithm ciphers with respect to differential attacks. We obtained entropy values near to an ideal value of 8, which is considered to be safe from brute force attack. Encrypted results show that the proposed scheme is highly effective for data leakage prevention and security.

Industry 4.0 is the fourth generation industrial revolution, which has grown exponentially from the Internet of Things (IoT) to the industrial IoT (IIoT)
The security and privacy in IIoT have been a hot topic for researchers since the evaluation of the industrial sector
Certificate authority assigns the digital certificates to nodes and peers, and it interacts with the software development kit (SDK) of certificate authority (CA).The client communicates with the client SDK, which generates a request to create a channel
Summary
Industry 4.0 is the fourth generation industrial revolution, which has grown exponentially from the Internet of Things (IoT) to the industrial IoT (IIoT). IIoT is applied in the manufacturing process, supply chains, monitoring, and management systems It deals with the connectivity of smart factories, machines, management systems, and other streamline business operations. It uses more sensitive and precise sensors than IoT, including more location-aware technologies on the supply chain side [2]. IIoT is the interjection of advanced machines and sensors in various industries, i.e. aerospace, health, energy, and defense These are the systems whose malfunctioning often lead to life-threatening or other emergencies. Image sensor-based solutions help in optimizing maintenance and work process safety They significantly improve the quality of productivity. Establishing reliability, scalability, and IoT management in these sensors is complex These new challenges demand safe and secure applications and devices without human intervention.
