Social media lockdown: 4 privacy features you won’t find in your settings
By Caitlin McGarry, TechHiveJan 22, 2014 3:30 am PST
You use a social network—at least one, maybe a few. Everyone does. You probably know all about your preferred network’s privacy settings, enough to make sure that the whole world doesn’t know your business. But if you’re paranoid—aren’t we all?—you can find ways to lock down your privacy that go above and beyond even two-factor authentication.
You have to start with your social networks’ settings, of course. If you don’t bother to limit the visibility of your posts or to make sure you’re not being tagged all over the place (thanks, facial-recognition technology), then there’s no point in proceeding. Facebook has the most convoluted settings of all the social networks, so follow our how-to for complete instructions.
After you confirm that your photos, contact information, and political musings aren’t on display for the world to see, you can take a few extra steps to safeguard your privacy.
Keep an eye on permissions
Every time you download a smartphone app, you allow its developers to see some of your information. Sometimes it’s as basic as your name. Other times it’s your address book, your Facebook or Twitter account information, your location, or your photos.
So how do you know which apps are raiding your contact list or have access to your photos? iOS apps must ask you upon installation for permission to access your contacts, location, Facebook account, and microphone, and you can easily grant or revoke such access from the Privacy section of the iOS Settings.
Android briefly had a hidden feature called App Ops that let you tightly control each app’s permissions, but Google withdrew the feature three weeks after its launch late last year. Nonetheless, in Android versions 4.3 through 4.4.1, the basic App Ops settings can still be accessed via third-party controllers like App Opps 4.3/4.4 from Color Tiger. You can use this app for granular permissions control of a wide range of Android apps (social or otherwise). Just be aware that App Ops is not an official Android feature, and third-party controllers have the potential to break the apps they hook into.
An app developer would like nothing better than to have access to all of your data, and sometimes such an arrangement makes sense. For example, if you want to share your Instagram photos on another social network, it’s logical for that network to request permission to see your camera roll. But that app doesn’t need access to your address book, which is why you should consider using MyPermissions as a central monitoring system to keep track of the permissions you’ve granted.
The service, available as a desktop plug-in and as an app for iOS, Android, and Kindle Fire, monitors any app connected to your Dropbox, Facebook, Google, LinkedIn, and Twitter accounts. If you use one of your social networks to log in to another site or app, MyPermissions will issue a notification.
Keeping your eye on multiple sites at the same time is easy enough, but what about the places you don’t visit or the networks you don’t care to sign up for? How would you know if your name is being bandied about like so much gossip in a small town? You can set up alerts with a fairly new service called Mention, a Google Alerts alternative for social networks.
Set up keyword alerts for your name—or whatever else you want to stay in the loop on—using Mention’s iOS and Android apps, website, or Chrome app, and set up filters for the places you want to watch (for example, Facebook and Twitter but not blogs or forums). As with Google Alerts, you can choose the frequency of alerts. Mention seems particularly useful for public figures or companies, and it offers paid tiers for big brands, but it’s a good way to monitor your social reputation.
You can stick with Google Alerts, but Mention offers a more pleasant user interface, more in-app context about the alert, stats about the frequency of your mentions, and the ability to interact with an alert—you can respond to a tweet without even leaving Mention, if you wish.
Just say no to geotags
We share photos on social networks without a second thought, but even a harmless photo can contain more information than you want it to. When you post an image, nosy folks can easily glean the location from the photo’s geotags, or the information your smartphone attaches to the photos you take.
Researchers at the University of California, Berkeley, and the International Computer Science Institute put together a super-creepy project that shows just how much information you’re sharing when you post on Twitter and Instagram—and those results are based just on your geotagged posts, not on the metadata from your photos. If you share enough images from a few places on a regular basis, stalkers can easily figure out where you spend the most time and use that to their advantage.
To avoid telling the world where you’ll be on a given day, turn off location services when you post on social networks. You can prevent your smartphone from attaching geotags to your photos by changing the camera’s settings.
Of course, if you take your privacy especially seriously, you probably don’t want to use a network that gives your information to its advertisers. New social sites and messaging apps are claiming to offer increased privacy in the form of encryption, secret groups, and use of peer-to-peer protocols to prevent tracking by corporate eyes (or the NSA).
BitTorrent, Sgrouples, Silent Circle, and Wickr are just a few of the bigger names in the secret social space, giving you ways to communicate without putting any of your data on the line.
