Vizio collected a selection of pixels on the screen that it matched to a database of TV, movie, and commercial content.

I would like to know more about that process. I find it ethically abhorrent, but technically very interesting.

Like, is it grabbing, say, three pixels in constant locations across the screen and matching their color change over time? Is it examining a whole block? Is it averaging a block at some proportional location on the screen?

A 2.2M settlement is absolute peanuts compared to the mountains of cash they likely made.

The reputational damage is in some ways will be bigger than the fine itself.

Sad truth is most users don't care and won't ever even hear about this. There might be an impact but it won't really hurt Vizio.

...I hope this is just pessimism. Trust me, I do.

It's not worth buying any of these 'Smart' TVs. I don't know whether it is a shoddy developer experience provided by the likes of Samsung / Vizeo etc or if it's the developers themselves (Hulu I'm looking at you) who do not maintain their apps which are constantly bug filled. I much prefer my old dumb TV that has a Roku plugged into it. Oh yeah, and I know it's not WATCHING ME.

Actually the TV's with Roku built into it are great. But again how do you know the Roku isn't watching you? I mean it even has a mic for voice search.

Earlier quoted context omitted.

> If you want a high end tv you don't have much choice. Don't connect it to the Internet? Barring the manufacturer sneaking a backup cellular modem in there, seems like it's an easy fix.

They can nag you about retrieving updates.

root it then! Any kid that knows how to point the libstagefright and DirtyCOW MetaSploit modules at the browser can root their "smart" TV...

I'm also curious if they'd be able to match different encodings of the same video or would only be able to match against specific encodings in their collection.

So I have a bit of intimate knowledge of this. Not sure what I can answer but for years my company worked on an Automatic Content Recognition project using tools from a team called Cognitive Networks who were bought by Vizio and makes up the tech that did this. If I understand correctly the founder of Vizio kept this tech for himself in the sale of Vizio. When developing this we would work directly with Cognitive che…

What proof do you have for what you're claiming, please? If you have intimate knowledge then you should know that many (me included) could accuse you of trying to push an agenda or divert the attention by posting what you did. How do you really know LG stopped their data collection? Sure they might have made a checkbox be switched off by default, but what does that say about the underlying software? IMO, nothing. It…

As a former Cognitive and Inscape employee, @mikeryan is largely correct. Note that fingerprinting happens on the TV - no actual content was sent back to us. Still absolutely creepy.*

With Vizio and other Dolby HDR compatible TVs you'll have to keep it connected if they intend to get firmware updates. I wonder which TV will be ideal for purchase, now that Samsung and Vizio have been caught hoodwinking their customers.

why do you want firmware updates? they will only bring more tracking

Fixes and improvements.

"Vizio has agreed to stop unauthorized tracking". As if there's any human-measurable way of confirming this. Yes they can be forced by a court. And no, the court can't know if they stopped all of the software copies on all TVs and no, the court can't know if they didn't re-activate them in the future back again. What actual proof do we have that LG actually stopped? What actual proof can we have that Vizio will stop…

Well, one could monitor all outgoing packets from your smart TV, but you would also need to know exactly how to decode what was contained those packets... unless of course they conveniently set the evil bit for you. With the poor level of development associated with this type of work, it would probably be enough to identify a different set servers for receiving the data.

With more sophisticated coding, you really do have to know what's in every outgoing packet. Perhaps it reduces down to problems similar to the discovery path of the VW Diesel emissions cheat - taking an interested hacker/researcher to examine the compliance.

Guess this is what spurred the investigation: https://www.propublica.org/article/own-a-vizio-smart-tv-its-... Still, how did this article come about? What is a whistle blower?

A whistle blower is a term for an insider who leaks a company's criminal practices to the government. They can get a percentage of monies recovered through lawsuits
