System and method of encrypting a derivative work using a cipher created from its source

A system for ensuring a legal distribution of a derivative work through public channels, comprising:

• a derivative work service server having a non-volatile memory, the derivative work service server being connected to a public network in such a way that it can be accessed by mix artists and consumers;
• and
• a software application stored on the non-volatile memory and freely available for download by the mix artists and the consumers, the software application comprising machine-executable code that permits the mix artists to upload derivative-encrypted works, which are derivative works encrypted using an encryption cipher derived from digital sources used to create the derivative work, and the software application further comprising machine-executable code that permits the consumers to purchase derivative-encrypted works and download the derivative-encrypted works, and decrypt the derivative-encrypted work provided that the consumers are respectively in possession a digital source for each source art work associated with respective digital sources used by the respective mix artists to create the respective derivative-encrypted works purchased by the respective consumers.

A derivative-encrypted work, comprising:

• an encrypted mix created from a derivative work encrypted using an encryption cipher created from encryption keys generated from digital sources used to create the derivative work;
• and
• a header section containing source art work identifiers that identify a source art work associated with each digital source used to encrypt the encrypted mix, as well as a marker associated with each digital source that indicates a start point in source data extracted for each digital source for generating a decryption key to create a decryption cipher to decrypt the encrypted mix.
