Purpose
This tool provides secure and private computation capabilities, directly supporting DSSC’s objectives of safer data sharing and data sovereignty.
About
This data app focuses on enabling privacy-preserving computations in data spaces. It leverages advanced Privacy-Enhancing Technologies (PETs), currently featuring Fully Homomorphic Encryption (FHE) and planned support for approaches like anonymization techniques and Zero-Knowledge Proofs (ZKPs). It is offered in the data space and delivered as a ready-to-deploy app to be instantiated in EDC connectors. It allows participants to process and compute encrypted data, preserving data privacy and enhancing data owners’ sovereignty over their data.

Community rating
Ranked by people who have used it, not by self-assessment.
Not Yet Rated. This tool needs 5 ratings before it gets a score. Until then it sits mid-catalogue rather than at the bottom, so a lack of ratings is never mistaken for a poor one.
