Data Privacy Center

Cryptographic computing enables computation on cryptographically protected data, providing you a broad range of privacy preserving techniques including secure multi-party computation, homomorphic encryption, privacy preserving federated learning, and searchable encryption. AWS cryptography tools and services utilize a wide range of encryption and storage technologies that can help you protect your data at rest and in transit. At AWS, customers can use Cryptographic Computing for Clean Rooms (C3R), a library that enables customers to collaborate with data in AWS Clean Rooms using a technique that allows multiple parties to jointly compute a function over their inputs while keeping those inputs private.

Differential privacy helps protect data at the individual level by adding a controlled amount of randomness to obscure the presence or absence of any single individual in a dataset that is being analyzed. AWS Clean Rooms Differential Privacy is a capability that helps customers protect the privacy of their users with mathematically-backed and intuitive controls using just a few clicks. As a fully managed capability, no prior differential privacy experience is needed to help you prevent the re-identification of your users. AWS Clean Rooms Differential Privacy obfuscates the contribution of any individual’s data in generating aggregate insights in collaboration outputs and enables you to run a broad range of SQL queries to generate insights about advertising campaigns, investment decisions, clinical research, and more.
