Summary
In summary, in this chapter, we have covered encryption, anonymization, and de-identification techniques in detail, along with some example Python implementations and a discussion of their limitations. We learned about the foundations and types of HE and secure multiparty computation and saw how they help in achieving privacy when working with ML models (including applications such as the encryption of training data, test data, models, model parameters, and inference results).
In the next chapter, we will learn more about confidential computing, why it is needed, and how it helps to protect us from privacy threats facing data in memory. We will also learn about securing ML models through trusted execution environments.
