摘要:
A method and apparatus for protecting regions of an electronic document are provided. According to the method, the entire electronic document is protected. The selection of a region within the electronic document is received along with identity of one or more users authorized to freely edit the selected region. The identified users are authorized to freely edit only the selected region of the electronic document. A request is then received to edit a region of the electronic document from a current user. In response to the request, a determination is made as to whether the current user is authorized to edit the region. If the user is not authorized to edit the region, the request is denied.
