this is cool. next up, row level encryption with private information retrieval methods for enabling queries and searches homomorphically (on data encrypted by the client that the service provider never has a key for).
- POPOSYS 4y agoThis is interesting - do you have any hits / docs on how to implement that?
- a-dub 4y agoit's an open area of research as far as i know. the technical terms are "private information retrieval", "private information query", "homomorphic encryption" and "secure multiparty computation." it's some of the coolest stuff in cryptography but it also tends to be experimental or very computationally expensive. zero knowledge proofs are the simplest form i know of. as far as i know, row level end to end encrypted databases with indices that preserve privacy do not exist yet, but i fully expect that they will.
