PETs report by the Royal Society
No interactive tool for exploration, but very useful and elaborate guide.
PETs adoption guide by the Centre for Data Ethics and Innovation.
"Interactive site [...] to help organizations consider how the adoption of PETs could unlock opportunities for data-driven innovation, whilst protecting the privacy and confidentiality of sensitive data. [The] guide is primarily aimed at technical architects and product owners working on projects that involve the sharing or processing of sensitive information."
The guide is related to our guide and has its own strengths and weaknesses. Most notably, they have repository of real-world use cases but they do not relate PETs to the GDPR.
Privacyontwerpstrategieën (Het blauwe boekje) (Dutch) by Jaap-Henk Hoepman
Dutch booklet that facilitates in translating vague legal requirements into concrete system designs. The booklet targets all organizations that process personal information, but particularly those individuals that build the processing systems or are responsible for the processing.
Blog “PETs voor de publieke sector” by Kristof Verslype (Dutch)
Short guide that also presents a decision tree. Includes more PETs but these are presented very shortly and without interpretation to the GDPR.
