  • Method and system embedding a non-detectable fingerprint in a digital media file
    Patent number: 8499159
    Abstract: The invention relates to a method and system for embedding in a digital media file user fingerprint which the user cannot detect when using the digital media file. In the method, a user-detectable watermark is first embedded in the digital media file. This watermark can be transformed in a client device to a non-detectable fingerprint of the user by utilizing digital media file-specific information issued by a digital media rights owner when the user has bought a user license. Afterwards the digital media rights owner can read the embedded user fingerprint from the digital media file if it is illegally distributed between other users.
