Metadata is information about computer-generated documents that is often inadvertently transmitted to others. The problems associated with metadata have become more acute over time as word processing and other popular programs have become more receptive to the concept of collaboration. As more people become involved in the preparation of documents, the more the likelihood of inadvertent disclosure. Many computer users are unfamiliar with metadata and the implications of creating and disseminating metadata. The issue is further complicated by the introduction of new programs, such as Microsoft's Office 2007. Teachers of Business Communication and Computer Science have a duty to educate their students to protect themselves from unintentional disclosure of personal information. (Contains 2 figures.)
