![]() That doesn’t mean social media companies don’t find any use for it, however. If you upload pictures to Craigslist, Facebook, Imgur, Instagram, Twitter, or WhatsApp, the Exif data won’t be available to the people who see them. Many other sites that let you display photos to friends or the public remove the Exif data before the images are shown to others. The service also has a setting that will strip out location data automatically when photos are uploaded. Flickr preserves Exif data by default, but users can change their account settings to control whether Exif data is available when others download their photos. If you post photos online, the details vary by site. Both services have a feature that lets you share photos without that information attached. That allows you to search for photos later by date and location. When you store your photos in Google Photos or Apple Photos, the Exif data is preserved. “When I met that person, I kind of educated them, saying, ‘Hey, maybe it’s a privacy concern for you,’ so they can make better decisions moving forward.” “I’m like, ‘I now know where you live, but I don’t really want to know where you live,’” Rajewski says. That matters to individuals-from college students to anyone selling things online-who communicate with people they don’t know well on the internet.Įxif data “can be a gold mine of information” that people don’t realize they’re sharing, says Jonathan Rajewski, a digital forensics expert and vice president at cybersecurity firm Stroz Friedberg, an Aon Company.Ī seller from Craigslist once emailed Rajewski photos of an item he was thinking of buying-with the Exif data still attached. If you email or text a photo, the Exif data will typically travel with it. “If you’re sharing images with people you don’t know or trust, you should be wary of whether or not you’re revealing sensitive information, like location data.” “There are some situations where you need to be careful,” says Bobby Richter, the leader of privacy and security testing at Consumer Reports. One thing we don’t know is whether he realized how much personal information he was posting online. For instance, the photographer shot with an iPhone X and had left the camera settings on auto. He was on a dirt baseball diamond behind a church in a small town in Ohio-a location we won’t name. Call up some GPS data, and you can learn where the boy was playing. As the shutter clicked, the time was 7:15 p.m. We can see that the picture is about a year and a half old the boy’s game took place on June 6, 2018. But download the file and click through some menus, and you can learn a lot. There is no caption, and few visual cues as to where or when the picture was captured. He is partly in shadow, but his face is outlined in sharp silhouette against the sky. The boy stands at home plate in his Little League uniform, bat poised above his shoulder. ![]() ★ Have fun sharing your General Public License v3.There’s a particularly arresting black-and-white image of a boy on Flickr, the photo-sharing site. So this app doesn't only have a stupid name and an equally stupid icon, it is also my (non-stupid) tribute to eggs. And I also happen to be a huge fan of eggs. The icon doesn't depict scrambled eggs either. ★ It doesn't really scramble the Exif data, it deletes it. Scrambled Exif does its job pretty well, but it could fail. ★ Please don't heavily rely on the data being deleted. ★ Scrambled Exif also renames the files (this can be disabled). If you want to know more about Exif, check the Wikipedia. ★ Basically, Exif is used by jpeg, which is the format in which your Android camera saves pictures. If you wish to help to translate this app to your own language, you can do so by translating these two projects using transifex: You can take a look at the code (and contribute if you feel like it) here: ★ READ_EXTERNAL_STORAGE to read the images other apps share with it. ![]() Now just share with the app you intended to share with in the first place. A moment later, the share 'dialog' will reappear. To remove the metadata from a picture, simply share it like you'd normally do and choose Scrambled Exif. If you don't want the big Internet companies (or whomever) to know where your pictures were taken don't forget to remove the metadata from them before you share them. Scrambled Exif (pronounced eggsif) helps you remove the metadata in your pictures before you share them.
