A Peek Under the Hood

ZeroDB is an end-to-end encrypted database that lets clients run queries without exposing the decrypted data to the server. The familiar client-server architecture stays the same, but query logic and decryption keys are pushed client-side. Since the server has no insight into the nature of the data, the risk is much lower. Even if an attacker successfully infiltrates the server, she won't have access to the unencrypted data.
