While acceptance of digital watermarking as a technology to protect digital media is constantly increasing, integrated applications are still comparatively rare. Two reasons are the challenge of secure key handling due to the symmetric nature of digital watermarking and the often high demand regarding computational power to embed a watermarking into a media file. We introduce a possible solution to this problem, the digital watermarking container. It splits the watermarking process in a preprocessing and a rendering stage. The watermarking key is only necessary at the first stage. At the second stage an arbitrary bit sequence with a fixed length can be embedded at a small fraction of the computational demands of a common embedding process. The second stage can be repeated multiple times to create a large number of individual copies at high speed.
