1. Don't post pictures showing personal data
Strangers and hackers aren't the only threat; people you know can steal your identity, too.
* Don't post any images with any identifying information whatsoever. No driver's licenses, marriage certificates, leases, or passports. You may think that's obvious, but do an image search and you'll see plenty of newly married couples, proud teen drivers, and world travelers posting high resolution pics of their documents.
* Even if you think your photos are private, more people might be able to see them than you think. On Facebook, friends of friends might be able to see photos tagged of you, if the photo's owner has the setting enabled.
2. Disable location services and geotagging
Cameras are increasingly sophisticated — even the ones on your phones. As you snap pictures, many cameras record information called EXIF data or metadata, including the camera's make & model, settings like speed and aperture, and the time the photo was taken. While much of this is helpful, it's just good for you to know you may be posting this info with a photo. Probably the biggest issue with embedded photo data is geotagging: when a GPS-enabled camera, memory card, or cell phone camera pinpoints your exact location in the metadata — even without your knowledge. Some social networking services strip that data out, but others include it — which mean you've essentially posted your home address online for anyone who knows how to view the geotagging data.
If your device includes this geodata as the default option, you'll need to disable it in your settings. If you're working with a point-and-shoot camera or a DSLR, you can find this through the settings menu on your camera — just look for a menu mentioning "geotagging," "location" or "geodata" and to be sure the feature isn't enabled.
Turn off geotagging on Android and iPhone
To disable geotagging on an Andriod device, open the camera app and be sure the "geo-tag photos" box in the settings menu is unchecked. On an iPhone, hit the settings icon, click on "location services" from the menu, find "Camera" and move the slider from On to Off.
3. Incriminating photos
Employers are increasingly hopping on the web to research potential new hires. Many businesses search the web for information about their prospective or current employees. Now, background checking companies like Social Intelligence Corp. have capitalized on this kind of job vetting. The FTC recently ruled that such companies can store your long-deleted online indiscretions for up to 7 years!
* Resist the urge to post "party photos" on social networks. And yes that means no pics with the red keg cup in hand, even if you were only drinking water.
* Keep the way you'd like to be perceived professionally in mind when choosing a profile picture.
* If friends tag you in an incriminating Facebook photo, untag yourself!
4. Cut out poorly cropped photos
While it's no security risk, there's little reason to choose Facebook profile photo with a stray arm or shoulder in it. If you're looking to meet people online on a dating site or social network, make the effort to choose a profile that features you, without the distraction of half of someone else in the picture. That someone else could distract anyone who looks at your profile — who is it? Where was it taken? Is that your ex? But keeping the focus on you is easy, thanks to free apps.
Improve your photos with these free tools
Photos editing services like Piknik or DrPic, can make cropping a snap. There's no need to use Microsoft Paint to edit a photo — if you need to tinker around with a shot, use one of these free services.
And pick an interesting one — you'll be far more likely to strike up a conversation with a potential match if your photo shows you doing something interesting, like playing the guitar or scuba diving.
5. Avoid webcam profile photos
To get a good shot of yourself, you're better off using any kind of point-and-shoot camera, a DSLR for the best image quality, or even your phone.
For a flattering outdoor photo, avoid the high-noon sun. Instead either take your own photo — or better yet, recruit a friend's help — during the early morning and late afternoon hours.
