Most automated processes require tracking of system status and performance, including operator responses to process upsets. Typically, this is accomplished using a physical notebook, as it is relatively tamper-proof. Using Ignition’s built-in Audit Log, this process can be done digitally, but it’s possible to alter and tamper with after data has been entered. In order to prevent tampering of the digital operator log, Corso Systems has built a tool using blockchain technology to ensure records are not changed, including distributed validation to ensure data integrity and limit the impact of bad actors trying to interfere with the system. This session will cover the implementation and methodology of this technology, real-world use cases, and show how this tool helps keep Ignition at the forefront of digital operations.

Introduction

6. • Digital record of everything that
happens in Ignition
• Stored in a database
• Can be tampered with given enough
know how and access to the database
Audit Log
• Provides a chain of trust for all events
tracked in the blockchain
• Tamper evident
• Public and Private blockchains allow
for different modes of determining and
enforcing trust
