Abstract: A document management device, when receiving information on a document registration user who is a requester for document registration and information on a document registration destination, provides a first page (top page) displayed when the document registration user logs into the document management device with a link (button) for accessing a second page for registering a desired document at the document registration destination. When the document registration user performs an operation of registering the desired document on the second page accessed through the link included in the first page, the desired document is registered at the document registration destination.

Abstract: When a document searcher transmits E-mail including a search condition to a document management system and searches for a document, a document search result can be obtained irrespective of an access right which the document searcher has. In order to solve this problem, the document management system searches a database for the document corresponding to document search information received from the document searcher, and transmits a message requesting a permission for the document searcher to obtain the document to a creator of the searched document.
