On Ashton Kutcher and Secure Multi-Party Computation (blog.cryptographyengineering.com)
from tedu to cloudsec on 02 Aug 2023 23:49

What Kutcher is really proposing is that we to develop systems that perform privacy-preserving computation on encrypted data. He wants to use these systems to enable “private” scanning of your text messages and media attachments, with the promise that these systems will only detect the “bad” content while keeping your legitimate private data safe. This is a complicated and fraught area of computer science. In what goes below, I am going to discuss at a high and relatively non-technical level the concepts behind it: what we can do, what we can’t do, and how practical it all is.
