I hope the spread of this sort of thing helps push forward general implementations of owner customizable Views and associated triggers of our systems and data rather then the long standing default of binary access/no access. All the technical foundations for this exist right now, and in the case of Apple in particularly they've already got it all together in every modern iDevice. They've got a well hardened and integrated HSM, data siloing and per-file class based hierarchal encryption ("Data Protection"), large amounts of sensors, biometric readers capable of discerning multiple inputs, and an interface amenable to adaption so that even regular users could intuitively understand a View system. Plus for mobile there is an entirely non-security related aspect which is growing in the public consciousness: our limited attention and mental focus budget.

With all that what I'd like to see is a simple interface to create arbitrary numbers of custom Views with associated triggers. The default one would be as we have it now: everything you load is visible at all times after unlock. But then you could create a new one, and select which apps (and in turn associated data in that app silo) appear and which preferences are accessible, then have a "This view will be made active when..." with nice UI for various key conditionals (time, geography, speed, network connection, biometrics, and/or password). It'd then be easy to ensure that while traveling between locations only maps, ride hailing and airline apps would be available for example. If anyone stole the device, or for that matter compelled it in any other way, none of my financials or private info would be available. I couldn't even be compelled to do it at that location, it'd be genuinely out of my control, backed by the same hardware crypto system providing standard FDE. This isn't even about government fully or even in large part, in dangerous parts of the world just as modern device net locks reduced the value of stealing a device a spread of "tourists and the like literally cannot be made to transfer money or the like on the street" could reduce the incentives for certain crime.

And again it'd be a very grokable common sense feature for the attention issue too. These days information overload and things trying to grab for some of our mindshare is a huge source of stress. I'd love if my devices, rather then always being a matter of adding on, started being able to actively help me subtract instead. I could compartmentalize work apps to only even "exist" away from home, no temptation or notifications even show up. And vice versa, entertainment distractions vanish as I enter certain locations. "Willpower" is something of a limited resource too and in practice often comes down to essentially planning ahead to avoid temptations in the first place, not going to the grocery store when starving for example. Our digital devices should be, at our individual direction, automatically helping us as humans. I think that'd be a valuable next step anyway, but the fact that vastly more powerful and user friendly coercion code type systems could be made widespread too would also be helpful in taking back some of the privacy digital can also take away.
