摘要：The invention relates to a method for protecting content comprising embedded copy protection data stored on an information carrier. In order to avoid that a user illegally circumvents a copy protection mechanism such as a watermark protecting said content to get an illegal access to said content, a method comprising the following steps is proposed: reading content from or writing content to the information carrier in response to an access command, storing said content in a memory, continuing to read content from or to write content to the information carrier and accumulating said content in said memory until enough content is stored therein to extract and evaluate said copy protection data.
