The ICO exists to empower you through information.

The following case studies are examples of how you could use or combine the techniques discussed in our guidance about privacy enhancing technologies (PETs).

If you are considering implementing PETs, these case studies will show you how you can do this in practice and what objectives you can achieve with these techniques. We do not require or encourage you to follow these techniques, they are simply examples of good implementation.

We have developed these case studies with organisations who use anonymisation and pseudonymisation techniques in innovative ways. These organisations collaborated with us voluntarily, and we did not pay or otherwise compensate them for doing so.

We will add further case studies as we develop them with organisations. If you are using PETs and you think other organisations would benefit from learning about how you use them, please contact our Technology team to discuss developing a case study.
