Usually, image editing programs offer the option to delete or not save these metadata when saving the images. There are certainly many tools and ways to remove the metadata. There are a lot of online services that remove metadata, but you should be careful about this, as it is often unclear what the services do with the information. But you may also not want to share the other meta information with others. If the GPS recording setting is not enabled, it will hopefully not be written to the image.
To counteract copyright piracy, additional steps need to be taken. It is very easy to manipulate the corresponding attributes. Profiles can also be created automatically for multiple images. If a photo is taken at home, the address could easily be found out. There is a lot of technical information about the recording itself and its storage.īut I now know that took a photo with his HTC One M8 on at 10:52, right here: For example, I use Exiftool, with which the following information can be read out: Tag There are a lot of programs that can read such metadata. My friend who brought me to this topic, kindly provided me with a photo taken by him. I don't want to go into more details here, but I wanted to introduce Exif briefly because it is probably the best known. The following table of the german Wikipedia gives a good overview of the various attributes: Tag-ID hex.Įxif is by far not the only standard used to store metadata. The presentation and storage of this data is standardised with Exif. The header of the image (JPEG or TIFF) also stores information on various recording parameters. The Exif standardĮxif stands for Exchangeable Iimage File Fformat. These data are added to the image by the camera (or mobile phone) independently and often without the photographer's knowledge. This starts with the time of recording, goes through the camera model to GPS information, if it has been saved. In the context of metadata for images, additional information is stored in addition to the actual image information (the color values of the individual pixels).

In this article I would like to point out which information can be stored in images and how to prevent this.
Pictures can tell you more about someone than he wants to. But not everyone knows what further information can be found in these pictures. Also here on Steemit many own pictures and photos are uploaded.
