      We also have to consider some external limitations: * Not everywhere has the infrastructure necessary to upload large datasets to the cloud * Most cloud providers are in not-great jurisdictions for some threat models. * Lying to border authorities, even by omission, ends badly.

      Fact is, the majority of "but why don't you just..." solutions in this space either require lying, reliance on infrastructure that may be non-existent or jurisdictionally compromised, or fails openly.

      By fails openly I mean that if you get dragged into a room and are forced to disclose exactly how you protected your data then you lose. The Shatter Secrets approach is fail-closed, it's designed to trigger extra-jurisdictional oversight in the (likely) case you end up in a room

      And "you" here is perhaps too broad, this solution was not designed to keep your vacation photos or text messages safe - the majority of your are low risk - it was designed with the priorties of journalists, activists and human rights defenders in mind.

      It was designed under the explicit assumption that people will get pulled into a room, without a lawyer, and made to divulge every little detail - because sadly that is the state of your human rights at the border.

      One issue we have when we approach funders with these technologies, is that they describe it as "high risk" - as if there was a lower-risk option available.

      Carrying data across borders is risky, if you can avoid it you absolutely should - @OpenPriv is also working on anonymous communication tech that can facilitate that - but for many people, in many circumstances, flying with an encrypted harddrive is the only option.

      So, given that we can't reduce the *risk* we look around and see how we can trying and *reduce the harm*. Which is where the success criteria comes from, we reduce harm by using technology to force the powerful to deny entry or comply to stronger jurisdictional standards.

      We reduce harm by allowing the person at the center to be 110% truthful, upfront - they can provide their device unlocked to border guards and give them an entire tutorial on how Shatter Secrets works.

      Shatter Secrets would change the dynamic from "X has refused to give us the key" to "X gave us a key and was completely compliant, but we need a warrant to access data from these N people and organizations" That is a different dynamic.

      So you encrypt the data with a public key whose corresponding private key is left safely at home? (Repeated N times.) (All credit to you if that's actually the technique; sometimes stating the problem is the main battlle.)
