Abstract
A method and apparatus for enabling a licensed end user to record digital data as described is particularly useful to the music industry as it enables them to make audio data available over the internet but to retain control of the uses to which that audio data can be put. Thus, upon completing a financial transaction to pay for the required audio tracks, the end user is enabled to download and decrypt encrypted music tracks and to play them on the end user's personal computer. The end user can also be allowed to burn a CD including the downloaded music tracks. However, the end user is only enabled to decrypt and record the music tracks onto the CD if the music tracks are recorded together with copy protection.
