Your TV Is Spying On You (www.ludlowinstitute.org)
submitted 1 day ago* (last edited 1 day ago) by Pro@programming.dev to c/technology@lemmy.world
 

You sit down to relax, put on your favorite show, and settle in for a night of binge-watching. But while you’re watching your TV… your TV is watching you.

Smart TVs take constant snapshots of everything you watch. Sometimes hundreds of snapshots a second.

Welcome to the future of "entertainment."

I watch TV through my computer using Jellyfin. Am I at danger?

[–] DFX4509B_2@lemmy.org 10 points 6 hours ago (3 children)

Mine ain't, I'm using an ancient dumb TV.

[–] Raiderkev@lemmy.world 2 points 3 hours ago (1 children)

I'm not, but I've disconnected the Internet from it. It can try all it wants to send the data to the mother ship.

[–] Lifter@discuss.tchncs.de 2 points 3 hours ago

Soon they may come with cellular capacity. Cars and e-bikes already do.

You gotta Faraday cage it!

[–] Ledericas@lemm.ee 1 points 3 hours ago

even better we dont use tv anymore, just a PC.

[–] camelbeard@lemmy.world 0 points 3 hours ago

99% of what we watch is from streaming (Netflix, YouTube, etc). A dumb tv with a Chromecast probably isn't any better.

[–] bstix@feddit.dk 11 points 11 hours ago (2 children)

Sometimes hundreds of snapshots a second.

That's a pretty neat FPS for a tv.

[–] camelbeard@lemmy.world 2 points 2 hours ago

The article states that's what the privacy policy sais samsung can sample every 500ms and LG every 10ms. It doesn't really mean they are, but it's definitely possible. A very basic way of detecting content is to take a 1000 pixels evenly spaced out over the screen and store the color values. That gives you something you can match against a database. You don't need to process a 4K screenshot for this.

[–] beveradb@sh.itjust.works 9 points 9 hours ago* (last edited 3 hours ago) (1 children)

Yeah I'm calling bullshit on that quote, I'd like to see proof of any smart TV having beefy enough hardware to record anything at 100fps+, and even then what would be the point? Nothing played back on the screen will even have a frame rate and 60fps... I'm sure this is a lazy article mistake

EDIT: I take it back, I talked it out with Gemini and understand the logic and realistic implementation now, it's a dedicated part of the SoC design. Still hate the fact that this is a thing, we just need to spread the word about not connecting your actual TV to the internet at all ever.

[–] Breezy@lemmy.world 1 points 3 hours ago

If they were recording so much couldnt tv makers be held liable for recording another companies property.

[–] aceshigh@lemmy.world 7 points 11 hours ago

I just don’t own a tv. Getting rid of my entertainment and gaming systems and most of social media was my answer to internal peace. I don’t have streaming either.

[–] DarrinBrunner@lemmy.world 5 points 11 hours ago

I guess I'll stick with my 2012 Toshiba 55" dumb TV.

[–] FG_3479@lemmy.world 9 points 13 hours ago (1 children)

The built-in OS on smart TVs almost always sucks. The built-in OS on our LG is slower, has less apps, and has less support for HDR and higher resolutions than our Fire stick.

Just don't use it and instead plug in a Fire stick, turn off its tracking, then sideload apps like BeeTV and HDO Box.

I know Amazon has a bad rep from a privacy standpoint but the Fire stick is super cheap compared to its competition and lets you turn off the tracking in one page of the settings menu.

[–] hootmcgoot@lemm.ee 4 points 10 hours ago* (last edited 10 hours ago) (1 children)

The article says the TVs still capture input and do recognition from external sources so using an external device is not helping.

Edit: Unless your tv is not connected to the internet.

[–] orb360@lemmy.ca 6 points 6 hours ago

The TV can still connect via weave, Amazon sidewalk, or other mesh networks through your neighbors doorbell or thermostat or whatever... Even if you never connect it, it could still report. Have to open it up and destroy the antennas.

[–] SaharaMaleikuhm@feddit.org 33 points 18 hours ago (4 children)

No, it's not. It has not connected to the internet.

[–] CriticalMiss@lemmy.world 10 points 14 hours ago (1 children)

Some TVs will sneakily connect to open APs to try and phone home. It is nasty but it does happen. You can only be worry free if you yank out the radio module. Some TVs make it easier than others (My LG TV made it as easy as opening the back of the TV and disconnecting, YMMV)

[–] Valmond@lemmy.world 1 points 11 hours ago

My TV isn't a "smart" tv.

[–] outhouseperilous@lemmy.dbzer0.com 4 points 13 hours ago (1 children)

Well, so, about that.

A lot of TV's will form mesh nets with same brand-or even across brands-, until they find one that is connected. I've even heard reports of one with a sim card¹.

¹in a 'smoke filled room'² ²okay it was a van. A smoke filled van. And she was on some other stuff too.

[–] ayyy@sh.itjust.works 3 points 12 hours ago (1 children)

Where can I read about these mesh networks?

Think there was an article in... I think wired a couple years back.

[–] Joelk111@lemmy.world 5 points 17 hours ago* (last edited 14 hours ago) (1 children)

My thoughts exactly. My Xbox is spying on me instead.

Yup same, running a shield

[–] AA5B@lemmy.world 10 points 18 hours ago (1 children)

Jokes on them: I watch videos on my tablet. There’s no way that’s spying on me, right? Right?

[–] eleitl@lemm.ee 1 points 5 hours ago

Not if your tablet runs an open source operating system without tracking. Like GrapheneOS or LineageOS, which both can be set up entirely without Google services, or sandboxing apps.

[–] kieron115@startrek.website 3 points 14 hours ago* (last edited 14 hours ago)

On my Sony Bravia running Android you can just disable the Samba app from running same as you'd disable any app in Android.

[–] atlien51@lemm.ee 14 points 23 hours ago (5 children)

What 4K TV can I buy that doesn’t do this guys help? Or should I stick to monitors???

[–] Steve@communick.news 3 points 11 hours ago (1 children)

Look for Signage Displays. They're basically TVs with different software.

[–] atlien51@lemm.ee 2 points 10 hours ago

Never heard of those before. Thanks

[–] Manalith@midwest.social 11 points 18 hours ago (1 children)

Sceptre still makes TVs that are just that, no underlying smart OS

[–] atlien51@lemm.ee 4 points 18 hours ago
[–] pool_spray_098@lemmy.world 21 points 21 hours ago (6 children)

I mean... Just don't hook the TV up to the internet. Don't join your WiFi network on the TV.

Kind of a simple solution.

Doesn't work anymore. They do dark mesh networks.

[–] atlien51@lemm.ee 12 points 20 hours ago (2 children)

No it’s not! I had a goddamn Sony tv and it wouldn’t let me change certain settings unless I connected it to the internet! They try to force your hand!

[–] kipo@lemm.ee 3 points 17 hours ago

Do you remember the model number? I would like to research this.

Until the cost of a sim card w/service is less than the revenue they generate from it. Which I fear is scarily close.

Spy all you want Agent Hisense of the Roku org, I've got you in a black box. Your communications have been cut! You'll never report back to HQ now!

[–] nonentity@sh.itjust.works 38 points 1 day ago (2 children)

I’ve never allowed my TV to have an active route to the internet since I bought it in 2019, it’s exclusively fed over HDMI by gaming consoles and an Apple TV.

The thing is, HDMI 1.4 added HEC, so what’s to prevent media players from serving as an Ethernet switch and providing an internet connection to TVs.

[–] tfowinder@lemmy.ml 6 points 21 hours ago (2 children)

HEC feature enables IP-based applications over HDMI and provides a bidirectional Ethernet communication at 100 Mbit/s

I think the bandwidth is too slow for HD/4K Streams.

I am sure the 100 Mbit/s must also be theoretical maximum, i would be impressed if practical cables supports even half the orignal specs

[–] WhyJiffie@sh.itjust.works 15 points 21 hours ago (1 children)

for streaming, yeah, for tracking its plenty

[–] cole@lemdro.id 4 points 11 hours ago

100Mbit/s is plenty for streaming even 8k

Does anyone know if there's a domain blocklist for smart TV telemetry? If so, I could easily put it into my DNS server, like I already do for ads.

I'd like to continue using my streaming apps without resorting to yet another device. I have an HTPC that runs KODI but I think it'd be a pain to replace all of my streaming apps.

[–] laserlizard@lemmy.dbzer0.com 10 points 13 hours ago* (last edited 13 hours ago) (1 children)

A couple I'm aware of:

But like flightyhobler suggested, if you keep an eye on your DNS logs with Pi-hole or managed services like AdGuard DNS and NextDNS you'll get a better idea of what's still getting through.

[–] alucard@sopuli.xyz 1 points 12 hours ago

Thank you for posting this! You saved me a search

[–] flightyhobler@lemmy.world 16 points 1 day ago

Turn the TV on and keep an eye on the logs. Many of the common blocklist already block that kind of telemetry.

[–] AlternatePersonMan@lemmy.world 130 points 1 day ago (2 children)

It's almost like we should have strong data privacy laws so companies can't spy on everything we do...

[–] Jakule17@lemmy.world 2 points 15 hours ago

European liberals are trying to weaken gdpr
