Microsoft SEAL is a homomorphic encryption (HE) library, developed by Microsoft Research.
With homomorphic encryption (HE), the encrypted item can be used on computation without decryption. For sensitive data (such as, privacy data in healthcare), the customers can operate their own data without submitting private text to cloud service providers. (See below.)
Click through to see how it all works. Homomorphic encryption is a clever solution to an important class of data security problems and I’m happy to see walkthroughs like this be available.
