Abstract:

With the development of internet, copyright protection of digital products is facing a historic challenge, the solution to which plays a crucial role in the development of copyright industry. To effectively protect the product copyright in digital network environment, we design a digital product copyright protection scheme. Every digital product gets a Digital Copyright Identifier (DCI) on the digital product copyright register platform, which can identify their copyright. Extracting DCI codes from the products by a specific watermark detection algorithm can get the copyright of the digital producst, which helps verify the copyright authenticity of the products and lay a foundation for detection, tracking, forensics, and preserving digital products’ copyright.

Key words: DCI code;digital product;copyright protection
