The plugin shows the metadata of JPEG images posted to the Internet and stored locally it also integrates with geolocation services and shows thumbnails. To do that we used a Firefox plugin called Exif Viewer 2.00. We tested some popular online services to see how they handle EXIF. However, as you’ll see from our test results, some sites that help people sell stuff strip out metadata to protect users. As far as other online services, stories abound of items in “for sale” posts being stolen, presumably a result of thieves figuring out their location from photo metadata. That really depends on the service - some delete it but others don’t. With social media and photo services, your privacy may be compromised.

While on the run from criminal prosecution for the alleged murder of his neighbor, McAfee was interviewed by Vice, which also published his portrait. One of the most prominent examples of metadata being used in a manner not intended by a photographer is the apprehension of John McAfee in Guatemala in 2012. Moreover, camera vendors might use a proprietary metadata format, partially redundant with EXIF.Įmbedded metadata, at times forgotten or ignored, can present a problem to both authors and the people in photographs. Other popular formats such as PNG and GIF might also contain similar metadata - in particular, Adobe’s XMP-based metadata. EXIF was developed for JPEG and TIFF files. The Exchangeable Image File Format standard was developed by the Japanese Electronics and IT Association (JEITA) and first published in 1995. One of the main metadata collectors is the EXIF block that is added to graphic files. Searching photo metadata is a method of doxxing, which is the practice of gathering real-world data, such as the real name and home address, on a person of interest online. It can be used to track you down, and to find more photos taken by you - and perhaps find some private pics among them.

This kind of photo information is more comprehensive than the likes of “2016 New Year’s party at our place.” Besides more esoteric attributes such as focal length and flash mode, the “note” might contain the model and serial number of the camera, the date of the photo, and, more important, geolocation data - where the picture was taken.

These days, one needn’t scribble comments on a photo your camera, an image-editing app, or the service you use to post your photo will add information for you. An old-school habit, labelling the back of photos, has transitioned into something more appropriate for the digital age.
