The title of the article is kind of a spoiler tho

+Sony, your smartwatch has a vulnerability and it's known and used for some time on +xda-developers

It's a good idea today to enable the encryption mechanisms offered on our mobile devices, if not a requirement in enterprise or medical environments.
Is using an Android Wear smartwatch a compromise in our professional or personal data protection?

No data protection on Sony Smartwatch 3 (Android Wear)
A few days ago, phoneArena published an article with this title: Hackers can grab personal data from your smartwatch. Because it was only linking to a teaser for a later release and we are using on…

So many good points from +Ron Amadeo

I liked particularly the reminder, based on data that arbitrary duration (2 or 3 years, 18 months or whatever) of updates and security fixes does not align with the needs in reality.

Yes, the article is based on fear; as some studies showed: security fears got old and tend to not lead to actions anymore.

So what can be done then?
Some ideas:

– Open Handset Alliance builds and updates continuously a public repository + test suite of all known Android and OEM vulnerabilities.
Free test apps and websites are provided for everyone to check their device.

– Google extends the requirement to access google services to every device license passing the vulnerability test suite as long as the device is still used by users logging as measured for the platform versions report.
Access to Google services wouldn't be revoked for existing devices but the security updates for existing devices would become a requirement to ship a new model.

– Google stops pretending that users are safe as long as they install their apps only from the Play Store.
Any Android app can download an external binary or java class from the web and execute it later: by design it can't be caught beforehand by a static code analysis.
They're safer but they're not "safe" as long as their device is vulnerable to known exploits.

Okay so calibrating the +Sony Smartwatch 3 display colors is gonna be tricky given how the measurements come out

Calculated from data: contrast ratio of 8:1.. yeah, nope that's not right ^^

However you can see quickly why colors on this display look so strange: the blue channel is way off and clips at IRE 82.
It might be a deliberate attempt of the people who profiled the panel to make it appear colder blue than the white point really has.
As you can see on the RGB Levels graph, there is tha much deviation between channels. If you saw the watch display in real life: you probably knew already.

I don't know yet what is it that makes darker values brighter than they should: it might be a content adaptive brightness algorithm tuned for readability.
As seen on the CIE Diagram there might be some more color processing going on as well.

The small size of the display is compared to the size of the X-Rite i1 Display Pro is not making things easy, I'll try tuning my patterns and using the i1 Pro instead.

Well, you gotta start somewhere right?
