Securing Industry 4.0: A Survey of Biometric Traits and Challenges

Industry 4.0, the advent of electronic industrial framework, is commonly referred to as the 4th industrial revolution and is progressing at highly growing rate as compared to the three former revolutions. Accessibility forms the fundamental basis for operation when there is a continuous exchange of knowledge between autonomous and efficient robots and business units. Workers play a vital role when utilizing emerging technology and exercising autonomy in decision-making. Employing techniques that separate individuals and their actions and reactions may be required. Enhancing safety measures, limiting access to restricted areas exclusively to approved personnel, and prioritizing employee welfare can yield advantages across the entire production chain. Hence, the collection of biometric data from individuals, whether with their awareness or without it, has the potential to facilitate authentication or monitor their emotions and cognitive states during their routine work-related tasks. After thoroughly examining the data, we have pinpointed three key domains where Industry 4.0 principles are integrated with the characteristics of biometric structures, traits and techniques. This review presents a inclusive overview of the many biometric functions used in the context of Industry 4.0, including their advantages, disadvantages, and practical uses. The study is now exploring new pathways to find innovative solutions.
