ICO: How can Privacy Enhancing Technologies help with data protection compliance?

How can PETs help with data protection compliance? At a glance • PETs can help you demonstrate a ‘data protection by design and by default’ approach to your processing. • PETs can help you to comply with the data minimisation principle by ensuring you only process the data you need for your purposes, and provide an appropriate level of security for your processing. • You can use PETs to give access to datasets which would otherwise be too sensitive to share, while ensuring individuals’ data is protected. • However, you should not regard PETs as a “silver bullet” for data protection compliance. Your processing still needs to be lawful, fair and transparent. • You should perform a case-by-case assessment (eg, through a data protection impact assessment (DPIA)) to determine if PETs are appropriate for your aims.
