Privacy-preserving architecture for genetic testing. Genotype data and encryption keys are generated at a certified institution (CI). The patient is provided the full key, which also is randomly split between the data storage and processing unit (SPU) and the medical unit (MU). The privacy-preserving algorithms for ancestry inference and genetic risk test computation take place between the MU and the SPU.
