Metadata
Metadata is information about something digital, rather than its contents. That can include details about the size of a file or document, who created it, and when, or in the case of digital photos, where the image was taken and information about the device that took the photo. Metadata may not identify the contents of a file, but can be useful in determining the sourcing of where a document came from or who authored it. Metadata can also refer to information about an exchange, such as who made a call or sent a text message, but not the contents of the call or the message themselves.
