Remove metadata from files2/14/2023 ![]() The metadata removal tools that exist today can be divided into four groups: The purpose of metadata removal tools is to minimize the risk of such data leakage. Since metadata is sometimes not clearly visible in authoring applications (depending on the application and its settings), there is a risk that the user will be unaware of its existence or will forget about it and, if the file is shared, private or confidential information will inadvertently be exposed. Metadata may be added to files by users, but some metadata is often automatically added to files by authoring applications or by devices used to produce the files, without user intervention. They can include information such as details on the file authors, file creation and modification dates, geographical location, document revision history, thumbnail images, and comments. Metadata can be found in many types of files such as documents, spreadsheets, presentations, images, and audio files. Metadata removal tool or metadata scrubber is a type of privacy software built to protect the privacy of its users by removing potentially privacy-compromising metadata from files before they are shared with others, e.g., by sending them as e-mail attachments or by posting them on the Web. ![]()
