Over the next 12 months, we will see greater adoption of privacy enhancing technologies (PETs) and their closer integration with AI systems. For several years, PETs have been highlighted as having the potential to aid data protection compliance, in a variety of different contexts. In its 2023 guidance on PETs, the ICO specifically cited privacy by design and by default; data minimisation; security; and secure data sharing as capable of being supported by PETs. However, since then we have seen only intermittent PET adoption by organisations. In the coming year, PETs such as homomorphic encryption and federated learning will be used increasingly to train AI models.
