In late 2012, John McAfee, the infamous founder of McAfee anti-virus software, was on the run from so many people – the government, thugs, the media, and the world at large. Let’s say he lives a pretty interesting life. But somehow, a reporter for Vice managed to find him, because the unknown man decided to post a photo online.
A curious reporter from The Next Web decided to browse the photo’s metadata (it’s not that difficult) and suddenly he learned that the photo was taken with an iPhone 4s on December 3, 2012 at exactly 12 :26:00 pm. Oh and he also has exact latitude and longitude coordinates. All he has to do now is import them into any map app and he has a map of the location.
The photo caused McAfee (left) to be caught.
Suddenly the whole world knew where John McAfee was. Suffice it to say that the rest of McAfee’s life was also full of adventure. Wired described McAfee’s exceptional life in a short Kindle e-book, and it’s definitely worth a read.
The point is this can happen to anyone, and you don’t have to run away to appreciate a little privacy in your life. You can share a beautiful beach photo on Flickr or Instagram without anyone knowing exactly where you are, not even your boss.
Have a plot? Let’s see how we can do that on iPhone and Android.
1. Turn off geotagging
Prevention is the best medicine. Most of us leave geotagging by default, and it can be helpful to remember exactly where you took the photo. But it is also something that follows you around. If you take the picture at your home and then upload it online, anyone smart enough to snoop will know where it was taken (and, by extension, now know where you live).
Hot Tip: Learn more about EXIF data and how to read it across different desktop and mobile platforms.
On iPhone
To prevent the camera from recording the geolocation for each photo, go to Setting -> Privacy -> Location service And off Camera select.
On Android
Thanks to the many different versions of Android and different manufacturers using their own different camera apps, the process on Android is not streamlined.
However, it is similar. Unlike iOS, location tracking is the job of the camera app, not the system. So the setting to turn it off is somewhere in Setting menu of the camera application. If you use Google Camera, it will prompt you to enable location saving when you first launch it. You can also disable it from Setting -> Save location.
2. Delete EXIF data on iPhone
Download the app called Koredoko and get started. Start the application and you will have to enable the free extension for it to be able to read the EXIF data.
Tap the menu button in the lower left corner and you’ll see all the photos in your camera roll listed here. Next to each file is a I icon.
Click it to see all the EXIF metadata for the image including geotags. Now tap Share at the top right then tap Save without metadata.
The app will save a new version of the photo without any kind of redundant personal data.
3. Delete EXIF data on Android
Photo Editor is a powerful photo editing software and it’s really useful Shipment mode where you can delete EXIF data for multiple files at once. It works and it works fast.
Launch the app, tap ShipmentLater +, and go to your photo archive. It is usually in DCIM -> Camera folder. Click on the photo you want to extract data from and press Finished.
Back from Shipment click on the page Mission and choose Format from the pop-up list.
A detailed task list will now display. locate EXIF options and choose To move. Click OK, wait a few seconds and the application will notify you that the conversion is complete.
The application makes a second copy of the file without any metadata. By default, images are stored in output folder but you can freely change the location from the task list.
private happiness
Now that the device data and personal location from the photos have been deleted, you can freely share your photos on social networks like Flickr and Instagram without having to worry about it.
