Popular smart TV models made by Samsung and LG can take multiple snapshots of what you are watching every second – even when they are being used as external displays for your laptop or video game console.
Smart TV manufacturers use these frequent screenshots, as well as audio recordings, in their automatic content recognition systems, which track viewing habits in order to target people with specific advertising. But researchers showed this tracking by some of the world’s most popular smart TV brands – Samsung TVs can take screenshots every 500 milliseconds and LG TVs every 10 milliseconds – can occur when people least expect it.
“When a user connects their laptop via HDMI just to browse stuff on their laptop on a bigger screen by using the TV as a ‘dumb’ display, they are unsuspecting of their activity being screenshotted,” says Yash Vekaria at the University of California, Davis. Samsung and LG did not respond to a request for comment.
Vekaria and his colleagues connected smart TVs from Samsung and LG to their own computer server. Their server, which was equipped with software for analysing network traffic, acted as a middleman to see what visual snapshots or audio data the TVs were uploading.
They found the smart TVs did not appear to upload any screenshots or audio data when streaming from Netflix or other third-party apps, mirroring YouTube content streamed on a separate phone or laptop or when sitting idle. But the smart TVs did upload snapshots when showing broadcasts from the TV antenna or content from an HDMI-connected device.
The researchers also discovered country-specific differences when users streamed the free ad-supported TV channel provided by Samsung or LG platforms. Such user activities were uploaded when the TV was operating in the US but not in the UK.
By recording user activity even when it’s coming from connected laptops, smart TVs might capture sensitive data, says Vekaria. For example, it might record if people are browsing for baby products or other personal items.
Customers can opt out of such tracking for Samsung and LG TVs. But the process requires customers to either enable or disable between six and 11 different options in the TV settings.
“This is the sort of privacy-intrusive technology that should require people to opt into sharing their data with clear language explaining exactly what they’re agreeing to, not baked into initial setup agreements that people tend to speed through,” says Thorin Klosowski at the Electronic Frontier Foundation, a digital privacy non-profit based in California.
They collect all this data and then still cancel the most watched/best shows.
Morons.
No wonder these things operate slow as shit!
So much more goatse and bathtube girl pictures along with porn are now gonna be on my tv
I wish I could go back in time to warn myself not to read this. The memory of receiving those (and other awful shit) is indelibly marked in my brain.
lol yeah! My friend where dicks and would set that to our screen savers or if we left our laptops open would go to meatspin.com and then lock your laptop. You got quite the surprise when you unlocked your computer lol
What the fuck are you talking about? Lol
Man wants to watch some kinky shit.
Don’t Google it. Just be happy you missed Liveleak and r/watchpeopledie.
And ebaum’s world. And rotten. And something awful.

I never own a smart tv, but can you flash custom firmwares into it?
The question now is, even if I don’t connect the TV to Internet, what TV brand should I buy? Currently I have LG, but no way I’m supporting that even without Internet connection.
Many video projectors don’t. My Epson doesn’t.
Yeah I get that. But I don’t want to use projector.
I can’t imagine using a TV. None of them are wall sized and I don’t have the space. Pull down screen fits the bill.
I can completely understand the use case, I just prefer the better display quality of a TV
that name invokes the old horror that is printers
I can top it - my first desktop PC was an Epson. Come to think of it, my first printer was an Epson dot matrix. Loud as fuck but it was a good little workhorse.
Epson printers are pretty nice, on par with Brother for usability.
Epsons were pretty chill printers. You could buy just the print head and you could use your own ink refills
hopfully they dont communicate locally with other lg or partnered devices
now or in the future
Like amazon ring devices? I think it’s called Sidewalk .
Fortunately these TVs are not yet sophisticated enough to communicate to the internet without your permission like Apple devices do now.
Well thing is, they all track you to some point.
Specs wise, LG still makes some of the best TVs. You want 4k 120Hz, they’ve got you. But if you feel morally unable to support a company that has opt-out tracking like this, you’re a bit more limited. I thought maybe Sony’s better, but nope. There’s instructions on how to disable ACR on their TVs too. Philips comes with Roku or Google TV, both of which snoop on you, but I don’t know if they do the automatic content recognition thing.
Dumb TVs exist, but good luck finding one with a decent resolution AND price.
good luck finding one with a decent resolution AND price.
That raises the question: is there one that has decent resolution and privacy, but is expensive? Those of us who can afford it should surely go for the privacy friendly option regardless of price. Boycotting the surveillance society that’s in full development is worth a lot.
Mine isn’t connected to the internet. Too bad so sad greedy fucks
I’d rather pay for pretty much all products up-front with money at purchase time rather than pay with my data.
Not gonna tell other people what to do, but for myself, whether it’s my car or television or search engine or whatever, I’d rather just pay the bill rather than having the manufacturer or service provider go data-mining my data to figure out how they can make money from it.
I think that YouTube is a great service. YouTube Premium, though, is ad-free. What I want isn’t no-ad stuff, but no-log policies. And there aren’t a lot of manufacturers selling privacy. And it’s hard to compare services and products based on that.
I’ll go one more step. I don’t want to go read through privacy policies and figure out what the latest clever loophole is. We had to deal with that kind of legal stuff back prior to standardization around a few open-source licenses, and it sucked.
And I don’t want to deal with privacy policies that change and maybe don’t do what I want.
What I want to do is look for a privacy certification, and let the certification agency deal with that.
I’m happy to see this, my wife and I were about to buy a smart TV. Now I’ll just get the dumb variant.
Now I’ll just get the dumb variant.
These don’t really exist on a consumer level anymore. What you’re looking for is called a commercial display, which is what’s used in businesses and hospitals.
No, they still exist.
Luckily they exist in smaller sizes still. I’m just getting a small tv for occasional use.
The only sensible way to operate these TVs is with no internet connection. We run our entertainment through an AppleTV. If that ever starts showing ads at rest, I’ll replace it with a Mac mini or a NUC. Fuck these companies and their race to the bottom.
I run a pi hole and it blocks 1000 attempts per minute from a single Samsung TV, then it outright denies requests from the tv. Duck those douches.
DNS sinks can often cause elevated traffic numbers because the client is constantly failing and retrying.
I bet if you enabled it to test the numbers would drop dramatically.
Those are just dns lookups.
It’s not just DNS. I have this rule in my firewall:
udp dport 15600 counter drop comment "Block Samsung TV shenanigans"So far, it has blocked 20575 packets (constituting 1304695 bytes) in 6 days and 20 hours.
I also see it with Wireshark on my network using the
udp.port == 15600filter.
wtf?
this is why you get a separate apple tv/android box and not connect your tv to the internet
Connect it to a Linux PC for optimal privacy.
Again, Samsung and LG is sniffing the HDMI port… So especially if you use another device like an Apple TV or Android or HTPC running Linux, only then Samsung & LG will record this data and sent back to HQ.
If you use a PC, there is no need to connect the TV to your WiFi, which means it won’t send any data.
Correct. Assuming your TV doesn’t connect to open wifi access points.
And assuming you never want to use any of the smart features or apps.
Like those things aren’t capable of the same shit?
anythings capable of it, but the companies behind the (premium) boxes have less of an incentive. While theyre all capable, its a matter if you have trust in them. At least for the Shield TV for example, go download a shield tv rom if you really don’t trust Nvidia. If you are paranoid that they all can do it, than any smart device can do it because its connected to the internet.
For example, it might record if people are browsing for baby products or other personal items.
Don’t mind baby products and dildos or whatever.
They could see bank activity and even login credentials when someone is temporarily displaying their own passwords.
This basically ignores all security measures regarding everything. Sensitive communication, company secrets and so on.
That’s fucking seriously huge. What the fuck?!
Jokes on them tho, they lack common understanding.
I watch a video about someone modding a shitbox and they think i can afford this new spyker sports car or any other 80k e car.
Obviously that shit is a swing and a miss. You want to give me advertising that suits me? Start by advertising stickers about cars because that’s something i could afford…not something i would buy tho.
Hmmm
