Finding relatives in genomic studies is tough when data is spread across multiple organizations with sharing restrictions.
SF-Relate is a new federated algorithm that uses a unique hashing approach to efficiently and securely identify genetic relatives by grouping individuals into buckets and only comparing those in the same group.
It ensures privacy through multiparty homomorphic encryption, allowing secure computation of relatedness without any private data being shared, successfully identifying 97% of close relatives in large datasets like the UK Biobank.
