Abstract: Systems and methods for enabling a user to obtain rights in a legitimate copy of a digital content unit without downloading the copy from a digital content store are provided. The systems and methods provide an encrypted copy of a digital content unit to a first user and transcript the encrypted copy to generate the legitimate copy to a second user. The encrypted copy is encrypted with a first encrypt key that may be associated with the first user and the legitimate copy is encrypted with a second encrypt key that may be associated with the second user.
