Sebastiao Pereira tries to preserve privacy:
Homomorphic encryption is a cryptographic algorithm that lets computations be performed directly on encrypted data without needing to decrypt it. This enables secure outsourcing of computations on sensitive data while preserving privacy.
Is it possible to have homomorphic encryption in SQL Server?
There’s a lot of effort and a CLR module involved, but it is possible. Now, my next question is, how well does it perform in practice? 10 patients is fine for a demonstration, but at what point does this tip over?
