Later, built-in microphones and cameras added features such as voice commands, hand gestures, and facial recognition, allowing you to control your viewing without so much as picking up the remote.

If a hacker gains access to your connected TV by exploiting a vulnerability, they could use those built-in cameras and microphones to spy on you and your conversations, while you sit transfixed on your couch. And if they hack your smart TV, they can use your Wi-Fi network to gain access to other devices on your home network, such as desktops, laptops, baby monitors, and even your "smart" appliances.

That made me laugh, and reminded me of the early-1990s Goodtimes Virus spoof. If a hacker gains access to your TV, they won't out themselves by doing something as obvious and stupid as that.

> Why do I mention the possibility of your smart TV getting hacked? According to a Wikileaks article from 2017, the CIA was doing exactly that to some Samsung models. That vulnerability has been patched, but you can be sure there are ongoing efforts in this realm.

> But the larger threat to your privacy comes from within. Smart TV sets use a surveillance technique called Automatic Content Recognition (ACR) to figure out what you're watching. By "watching what you watch," whether it's on streaming services like Netflix, cable, satellite or broadcast TV channels, even DVDs or video games, ACR can identify the content by comparing snippets of onscreen data with a database of known recorded works. If you've ever used Shazam on your phone to identify a song, you can see show this would work on your TV.

If it can determine what kind of shows you watch, it may be used to recommend similar content. But it exists primarily to collect your viewing data and sell it to data brokers. Your viewing profile is bundled with your IP address, from which your approximate location and socioeconomic status can be determined. You can then be targeted with ads on your TV, smartphone, and desktop computer for products that fit your profile.
> 
> A study done by Northeastern University found that many smart TVs sent the ACR data to Amazon, Facebook, and Google. ACR viewing data was also sent to Netflix, even if the service was not present or activated on a set. Targeted ads are common on the Internet. You visit a website selling shoes, and you see ads for shoes. The same is happening as you "surf" the content on your TV screen.

> In 2017, Vizio was fined $2 million by the FTC for selling this data without disclosing the surveillance to customers. Such disclosures are now mandatory. The "permissions" are granted (on an opt-out basis) by the user during setup, and the option to disable data collection is available in the TV settings. But each manufacturer calls it something different, and it can be hard to find the privacy settings. Samsung calls it Viewing Information Services, on Vizio sets it's Viewing Data. LG calls it Live Plus, and Sony has Samba Interactive.

> Consumer Reports has instructions for turning off ACR on most major TV brands, including Hisense, Insignia, LG, Philips, Samsung, Sharp, Sony, TCL, Toshiba and Vizio.

> You should also check the privacy settings on any streaming services you use. Here's how to find those settings for Netflix, Hulu, Amazon Prime, Youtube, Roku. You'll want to check for things like deleting your watch history, ad tracking/personalization options, Data Monitoring settings, and turning off interest-based ads.

> What About Those Cameras and Microphones?
> 
> Built-in cameras can be used to enable hand gestures to control your TV. LG sets with embedded cameras have supported hand gestures for a decade. Sony's Bravia Cam allows you to use hand signals to pause, adjust volume or turn off the TV. But it will also scold you if you're too close to the screen. Microphones and speech recognition tech allows you to change the channel or search for a show.

> As I mentioned earlier, a determined hacker with knowledge of a remotely exploitable vulnerability could use your TV set as a way to watch you. Even if you're not concerned about hackers, do you really need to control your TV by pointing or grunting?
> 
> Check the settings to see if these features can be disabled on your TV. Or if you can find the camera on the face of your smart TV, a piece of black tape can be used to cover it.
> 
> In closing, here are a few more tips to boost the privacy and security of your smart TV:
> 
>  
> Find out what kinds of data your specific model is collecting, what is done with that data, and how you can limit that. This information should be in your manual, or on the vendor's website. Search online for your TV's model number and the word “privacy.”
> Don’t rely on factory settings. Explore the privacy settings on your set, and change any default passwords if you can.
> Check the manufacturer's website to see if there are any updates or security patches that can be applied.
