My latest Locus column is "What’s Inside the Box," a discussion of whether owners, users or third parties should be able to know and/or control what their computers are doing:
The answer to this that most of the experts I speak to come up with is this:
The owner (or user) of a device should be able to know (or control) which software is running on her devices.

On the one hand, TomTom could generate trustworthy readings by completely locking its device so that users can't inspect or modify their operations, which would open up the possibility that your device was recording and transmitting information about your location and movements without your knowledge or permission. On the other hand, TomTom could produce a stats-gathering app whose workings were publicly disclosed, but which used a TPM-style module to verify that it hadn't been modified for the purposes of gathering and signing information that you can pass on to the insurer.

It would also give TomTom owners the choice of booting into alternative environments that did different things.
