Yeah, I do @musllibc, FOSS & infosec stuff. But now is not the time for a mostly-/only-tech Twitter feed.

      1/ We’re about to get UNCOMFORTABLY geeky. But, if I am elected to Congress - this is my plan to fix @Facebook, @equifax and others. The core problem here is we don’t have control over how our information in used. I want to mandate certificate signing. https://en.m.wikipedia.org/wiki/Certificate_authority …

      2/ If you have a Windows PC or a Mac, any program MUST have a certificate signed. It’s basically an encrypted file that proves they are they who they say they are. Apple can nuke any program from running by revoking that certificate. I want to give you that same control.

      3/ Lose trust in Facebook? Revoke their certificate. Same with Equifax. Malicious third parties can’t copy data and run with it. This puts YOU in control of YOUR information. And frankly, it puts you in a better position to make money from it. I want to mandate that technology

      I don't get it: if I lose trust in Facebook, revoking their right to run on my devices stops them from collecting new data, but doesn't destroy the data they've already collected.

      It would with this technology. It would make it absolutely unusable for them.

      Brianna is talking about CSEK rather than certificate signing. However CSEK requires cumbersome controls and infrastructure if every request to decrypt data requires getting the client supplied encryption keys.

      Ah, I see. And probably regulator-required audits to make sure you don't copy the data elsewhere while you've got it decrypted for some other justified purpose.

      Yup. But it's not as simple as "just revoke a certificate". It has reliability tradeoffs *or* it requires trusting the infra provider to enforce the key handling.

      The workable form would probably be "illegal, with stiff penalties and punitive damages owed to the person violated" for transfer or use of PII without a currently-valid certificate chain authorizing use.

          We probably don't want to insist that everyone learn how to securely manage private keys and certificate chains in order to have control over their own privacy ... some sort of trusted intermediate to hold keys ... OAuth to tell them to hand out short-lived permission ...
