Hidden Data & Metadata Frequently Asked Questions
What Are Metadata And Hidden Data?
The word metadata means "data about other data". Metadata is commonly embedded in electronic files and contain various types of information such as the creator name and the organization he belongs to, the creation and modification times, and the device or software used in the creation and processing of the file. This metadata is usually generated automatically by the software or device used to create the file, often without the user is even aware of it.
Hidden data in a file refers to every type of data that is not visible at all when using a standard viewer, or under certain settings, even though it does reside in the file and can be viewed by changing the viewer setting or by using special software to reveal the hidden data. Common hidden data types include comments, document revision history, and presentation notes. Many applications also embed various application specific hidden data.
Strictly speaking, in most applications metadata is one type of hidden data, however, often the two terms are used interchangeably.
Where Does Metadata And Hidden Data Can Be Found?
Virtually every popular file format contains hidden data and metadata, including Microsoft Word, Excel®, and PowerPoint® documents, OpenOffice™ Writer, Calc, Impress, and Draw documents, and PDF documents. Metadata can also be found in various image and media file types such as JPEG, PNG, SVG, AVI, WAV, MP3, and MP4.
What Risks Does Metadata And Hidden Data Pose?
While hidden data and metadata are useful for finding files and reviewing documents, they pose privacy and confidentiality risks when the files are shared. The hidden data often contains private and sensitive information, that if unintentionally exposed can cause the document creator and his organization embarrassment with possible financial and legal implications.
