Latest updates
19 June 2023 - we have created new PETs guidance, which is aimed at data protection officers and others who are using large personal data sets in finance, healthcare, research, and central and local government
This guidance discusses privacy-enhancing technologies (PETs) in detail. Read it if you have questions not answered in the Guide, or if you need a deeper understanding to help you apply PETs in practice.
The first part of the guidance is aimed at DPOs (data protection officers) and those with specific data protection responsibilities in larger organisations. It focuses on how PETs can help you achieve compliance with data protection law.
The second part is intended for a more technical audience, and for DPOs who want to understand more detail about the types of PETs that are currently available. It gives a brief introduction to eight types of PETs and explains their risks and benefits.
