  In recent years, there has been a significant proliferation of industrial
Internet of Things (IoT) applications, with a wide variety of use cases being
developed and put into operation. As the industrial IoT landscape expands, the
establishment of secure and reliable infrastructure becomes crucial to instil
trust among users and stakeholders, particularly in addressing fundamental
concerns such as traceability, integrity protection, and privacy that some
industries still encounter today. This paper introduces a privacy-preserving
method in the industry's IoT systems using blockchain-based data access control
for remote industry safety monitoring and maintaining event information
confidentiality, integrity and authenticity.
