We all love sharing photos, whether it’s a snap of your lovely breakfast or a great image of the setting sun. Perhaps you share those photos on Flickr, or maybe even Instagram, Twitter, and even Facebook.

But how much information are you giving away when you share snaps online? What can malicious users (such as identity thieves) learn from your photographs and do with that information?

Here’s everything you need to know about your photos and online privacy.

1. Who’s In the Photo

Photographs contain a wealth of information. A considerable amount can be read from just a few minutes examination. Take a simple portrait of a friend or loved one, for example. They might be wearing a watch, holding a newspaper, eating a sandwich, whatever.

But in that single moment, a viewer might learn:

  • The subject’s approximate age.
  • The type of clothes they wear.
  • What time the photo was taken (the watch).
  • The date of the photo (based on the newspaper date or headline).
  • What flavor sandwich the subject enjoys.
  • Potentially, the subject’s political views.

Individually, these pieces of information are quite useless. But there is possibly enough in this photo to target a loved relative: they can be recognized in the street by their photo and clothes; perhaps spotted in the supermarket buying a sandwich filling; their likely whereabouts determined by the time on their watch.

That’s all from just one photo.

2. What’s In the Photo

Meanwhile, a still life snap can reveal your own habits.

Perhaps you’ve snapped your breakfast. Maybe it was something very low in carbs; that immediately tells the identity thief that there’s a strong chance you’re on a diet. Do you need to use a specialist shop to pick up some foods?

On the other hand, if you took a photo of a prized possession, such as a guitar or a new smartphone, then you may have just made yourself a potential target for someone looking for gear they can easily steal and pawn.

You wouldn’t expect your friends to steal from you, or target you for identity theft, but if you’re sharing those photos online, can you be sure only your friends are viewing the photos? We’ll come to that a bit later.

3. Where Was the Photo Snapped

Unfortunately, it’s easy for unwanted viewers of your photos to ascertain where the picture was taken. A photo of a location might tell an identity scammer where you are at a particular date or time.

Taking photos of the lake during sunset? You’re in a remote location, with your attention focused on your camera. The personal risks here are obvious.

There’s also the problem of your home’s security while you’re out. If a series of similar photos taken over a range of dates are published, are you advertising the fact that your home is empty? Does your property have adequate security? This is one way thieves know you’re on vacation and away from home 7 Ways Thieves Can Tell When You're on Vacation (And How to Protect Yourself) 7 Ways Thieves Can Tell When You're on Vacation (And How to Protect Yourself) Vacations can leave your household security at risk.

4. The Photo’s EXIF Metadata

There is a very good chance that you have no idea what EXIF metadata is. Now is the time to change that. See our article on what EXIF metadata is in photos What EXIF Photo Data Is, How to Find It & How to Understand It What EXIF Photo Data Is, How to Find It & How to Understand It Pretty much every digital camera available today records EXIF data within each image you take. The data is useful for improving your photography and can also be quite interesting, especially if you're a geek. Read More .

Just as this article has descriptive tags attached to it, so photos have their own tags. These are grouped as metadata, known as EXIF, and contain a whole host of information. Everything from the make and model of the camera, to the ISO rating, exposure time, aperture size, and more are stored as EXIF metadata.

However, other data is also recorded. The date when the photo was taken is recorded, as is the location. If the EXIF data isn’t stripped by your preferred sharing service, this information can be easily decoded using a tool like pic2map.

Dedicated websites can display the location of photos based on their EXIF data.

Removing EXIF Metadata From Photos

If you share your photos online, you need to do it securely. Start off by choosing a service that strips EXIF metadata—Facebook and Instagram do this with all photos. You should also be using a service that enables you to restrict your account to approved contacts. Again, Facebook and Instagram provide this facility, as does Twitter.

As for Flickr, it is possible to restrict EXIF data from being viewed via your account’s privacy settings. Note that this cannot be done on an individual photo basis; instead, you’re limited to disabling or enabling public EXIF data across your entire account. Note that you can manually remove EXIF data before uploading 3 Ways To Remove EXIF MetaData From Photos (And Why You Might Want To) 3 Ways To Remove EXIF MetaData From Photos (And Why You Might Want To) Did you know that most cameras embed hidden information, called metadata, into every photograph taken? And when you share those images, say by uploading them to a social network, that hidden information often stays embedded? Read More .

Meanwhile if you’re sharing snaps from your smartphone over a messaging service like Snapchat, can you be certain that the recipients aren’t archiving the photos you send? If you cannot trust the recipient with the photo, don’t send. The same goes for any other method of sending photos

Check Privacy Settings and Privacy Policies

Concerned about how much information you’re sharing in your photos? By now you should be giving serious thought to the privacy settings on your social accounts How to Secure Your Social Network Privacy for the New Year How to Secure Your Social Network Privacy for the New Year People are starting to wake up to the threat an unsecure social media account poses to their online privacy and security. It's time you secured your accounts. Read More .

But as well as reviewing these, check the privacy policies on those sites as well. It’s one thing to prevent a photo from being shared; it’s another entirely to let it be used only to find that the website is using your image in promotional material (which it can do without asking). All of a sudden, your day-to-day life is being shared with the world!

As with any online activity, you need to ensure that what you share doesn’t impact on your personal safety. To recap, here’s what you might be giving away:

  • Who is in the photo
  • What is in the photo
  • Where the photo was snapped
  • The photo’s EXIF metadata

If you’re concerned about any of these things, take the time to revise your settings. This might mean putting a pause on uploading photos for a while; it might even mean disabling your photo sharing account until you’re certain your photos are accessible to the right people.

In extreme cases, you may even want to try a social media detox How to Do a Social Media Detox (and Why You Should Right Away) How to Do a Social Media Detox (and Why You Should Right Away) A social media detox might sound like a punishment; but if it does, there's a really good chance you need one. Here are the signs you need a detox and how to do it. Read More to get away from the temptation to always be uploading your photos for everyone to see.

    So the bottom line is one should not post pictures online because a determined, as well as ill-intentioned, miscreant can determine one's entire life's history from them. If one has the irresistible urge to share one's pictures, one should do it in person.

    BTW - I do not upload any images. I do not have the urgent need to brag about the places I've been and with whom. By the same token, I do not feel the need to vicariously share other people's escapades. The vast majority of pictures have a meaning only to the people involved in the picture. To others, they're just photographs. Sometimes they may be nice photographs, but lacking context.

      "Lacking context", like your comment. Ok so you don't share images online, could we encourage you to do the same with your opinions too? (You obviously have no issue with boring us with your profession of a monk like existence and lack of intellectual curiosity).
