Many multimedia documents are produced and distributed widely for many applications.
And those many multimedia documents are spread fast through the Internet. But there have
been illegal behaviors that many unauthorized users transform multimedia and use illegally
so, legal issues for copyrighted multimedia arise as a necessary consequence. In this paper,
we propose a procedure for secure watermarking using authentication key when a multimedia
document is used by authorized user in the Internet or distributed information systems. Before
a client requests using a multimedia document from the application server, the user acquires
authentication key from the authentication server. And then the application inserts a
watermark into the multimedia document comparing the client's authentication key with that
of authentication server. And the authentication key is inserted into the multimedia as a
digital watermark. The proposed digital watermarking algorithm can be used for inserting
authentication number like serial number of the multimedia. So, the owner of the multimedia
document can get copyright based on authentication server. Using the digital watermark with
authentication number of a multimedia document the owner of the document can assert
copyright ownership.
