In this chapter, using IBM Watson Studio, we will walk through the construction of a functioning cloud-based human identification system using biometric traits. We will first introduce biometrics and consider what we mean by biometric data. Then, we will explain the types of preprocessing needed for each biometric. Additionally, we will learn about the process of how to extract meaningful features from biometric data. Lastly, we will cover the concepts behind multimodal data fusion.

The following topics will be covered in this chapter:

• Understanding biometrics
• Exploring biometric data
• Feature extraction
• Biometric recognition
• Multimodal fusion
• Our example
