Abstract [en]

Watermarking embeds a signature in digital documents such as video and can be used for discarding illegal copying. Individual watermarking means that every customer receives an individual document that can be traced back to the customer if he is a pirate. Multicast is a way to distribute the same digital object to many users without the need to send one specific copy to each user. To combine distribution of individually watermarked documents with multicast might at first glance seem to be impossible. During the last years some methods have been developed to achieve that type of scalable distribution of individually watermarked documents. Some of these methods use special overlay networks to embed the signature and other use cryptography to produce the watermarks.
