# Working with personal data

This chapter will explore essential aspects of working with personal data, including the legal grounds for processing such data. You will learn about the different legal bases for collecting and using personal data, such as consent, public interest, and legitimate interest, and how to determine which one applies to your research.

Additionally, we will dive into the differences between anonymous and pseudonymous data. Understanding these distinctions is key to data protection, as anonymous data cannot be traced back to an individual, while pseudonymous data still allows for potential identification with additional information. You will explore how these types of data impact privacy risks, legal requirements, and the methods for managing data throughout your research project.

By the end of this chapter, you will have a clearer understanding of how to handle personal data ethically and legally, ensuring compliance with data protection laws while protecting the privacy of individuals involved in your research.
