Summary - X.1771 (04/2024) - Security guidelines for combining de-identified data using trusted third party

De-identification is a process to remove the association between a set of identifiable attributes and the data principal. Appropriate de-identification techniques should be used by an organization to balance between its desires to protect data as the data controller and to use the data in new and innovative ways.
Recommendation ITU-T X.1771 provides security guidelines for information and communication technology (ICT) service providers acting as data controllers and for trusted third parties fulfilling the role of combining de-identified datasets. The purpose of these security guidelines is to reduce risks, protect data and promote the utility of the dataset.
