Microsoft has established itself as a pioneer in trustworthy computing. Features such as Always Encrypted in SQL Server show how we continue to keep trust while making world-class products. We imagine a world where user privacy is preserved by using state-of-the-art cryptography while enabling better AI and data analytics products. In this talk, we will discuss how homomorphic encryption, a new encryption technology, is making all this possible. We will also show how this technology is being built into existing data analytics/ML/AI frameworks.
