Hi,

We are trying to get HWID from device. We already have a private extension that calls some chrome code. We are thinking to read HWID in the chrome code as well. But I don't know how I can get HWID in the first place. Do you know how to get HWID info? Thanks a lot!

Do you need the board ID or the serial number? Or something else? Basically chromeos::system::StatisticsProvider is your friend, but note that some of that data becomes unavailable after OOBE in order to prevent privacy hiccups. I assume you've talked to the privacy folks already to get clearance for what you're doing?

that is used to identify the model of the unit. That data isn't especially
sensitive, since it's not unique to any individual unit.

The HWID is available at shell prompt with this command:
crossystem hwid

I'm assuming this can't be done from inside an extension, though.

We discussed with privacy folks before and the discussion is still alive. I will cc you in the other thread in case you are interested.

to identify the model of the unit.  That data isn't especially sensitive,
since it's not unique to any individual unit.

The HWID is available at shell prompt with this command:
    crossystem hwid

I've heard a different opinion before though, but hopefully it's possible.
