My bets for the actual story behind this are: 95% a criminal hiding evidence 4.99% an autistic attempt to "keep his privacy" for no reason at all 0.01% a genuine need to keep something away from the government

In all cases just don't cross security checks with evidence you wouldn't want to be seized, its not that hard

I co-wrote a border search guide for EFF some years ago. I was very interested in finding clever technical approaches but I later ended up feeling that I hadn't given enough thought to the overall threat model questions (even though the guide did address them, perhaps even somewhat usefully). The big picture problem is that the agents performing the searches have an enormous amount of power in terms of potentially se…

So I guess what you really want is a duress PIN that loads into a fake innocent profile.

Earlier quoted context omitted.

Sounds like a feature that under right circumstances can land you in Guantanamo for 5 years where eventually you get cleared once the real terrorist gets caught.

The real terrorist were the cops.

Then you stay in Guantanamo indefinitely

Seems like they’re going to have a struggle proving intent. “I was stressed out and afraid and I got the passwords mixed up” would be the magic words I’d hear as a juror and I wouldn’t be able to vote to convict.

Surely they'll just dig into as to why he set up the feature originally?

'I don't want some sketchy phone mugger to end up with sexy photos of my girlfriend/myself' would seem like a plausible reason to me, if I was a juror.

> The big picture problem is that the agents performing the searches have an enormous amount of power in terms of potentially seizing devices and potentially denying entry for non-citizens. I think they should not have this power, but the agents and courts probably don't care that I think that.

That's the reason I never traveled to the US and never will, just having IT security in your CV is enough to make the border gamble not worth it

If they were searching for evidence of a crime, what crime was it?

The crime of disagreeing with the President.

The downvotes you get on this website for being completely correct never cease to astonish me.

I'd like some filter where if a comment is downvoted by IP addresses located in USA, they are considered as upvotes.

Exactly. People complain police dont prevent crime, but dont realize that is not their purpose. The police exist to protect the government, not the people.

Which part of the government protects the people?

The part that is afraid of not getting voted in next election. As long as they make the voting ticket a two party/person race and ensure that their voters believe the opposition is the literal devil, then they don't have to be too afraid

Luckily that has never happened /s

For non-graphene users (eg. Boring iPhone people like me). So there’s a feature called Duress PIN which as explained through some comments means you put a different pin which intentionally wipes the phone. It’s not auto wipe or wipe after several failed attempts but intentional wipe of device. (Worth explanation as the current title nor the article doesn't easily explain this was made by the US citizen providing the…

PIN to wipe seems suspicious. How about a PIN where it login to a patriotic profile and phone looks like normal android.

This is extremely hard to implement in a non-superficial way that would be hard to detect.

Android switched from block device encryption to filesystem-based encryption (with encryption data and metadata). This provides many security improvements, such as per-file encryption keys and per-profile keys.

However, this also means that the main file system is readable and you could enumerate the available users. If you would encrypt/obscure that information, you could still infer the presence of other profiles from file system block allocations.

(Disclaimer: not an expert, but I read the relevant Android docs at some point.)

Or that just selectively wipes only stuff you have marked for deletion. That way the profile stays up to date and believable.
