Research on Digital Product Confirmation Identifier and its Application Mode in Copyright Management and Transaction

In recent years, with the rapid development of digital media and big data techniques, ownership management and transactions for digital products (including digital media contents and data resources, etc.) have received increasing attention. As a core element in the process of copyright management and transaction, the confirmation identifier has played a vital role in it. In this paper, by summarizing and analyzing the existing methods of generating and applying various digital product identifiers, for the two different forms of digital products, digital media contents and data resources, we proposed a unified method for generating confirmation identifiers and the confirmation identifier constituting rules, which are suitable for their own characteristics respectively, and put forward the corresponding application model of the confirmation identifier in the digital product copyright management and transaction process, in order to give a better play to the role of the confirmation identifier. And further regulate the copyright and transaction management of digital product through the use of the confirmation identifier.
