A derivative work is encrypted using master keys generated from source data extracted from digital sources used to create the derivative work. A software application permits a mix artist to encrypt and stream a derivative work to a worldwide web server, where it is made available to consumers. A software application permits the consumers to acquire and decrypt an encrypted derivative work if the consumer has possession of a corresponding digital source for each of the digital sources used to encrypt the derivative work.

System and method of generating encryption/decryption keys and encrypting/decrypting a derivative work

A derivative work is encrypted using a cipher created from digital sources used to create the derivative work. A software application made available for download permits a mix artist to generate a derivative-encrypted work from a derivative work that the mix artist has created using one or more of the digital sources. The derivative-encrypted work is streamed to a worldwide web server, where it is made available for download by consumers for a fee. The software application is also available for download by the consumers and permits the consumers to purchase and download any available derivative-encrypted work. However, the derivative-encrypted works can only be decrypted if the consumer has possession of a digital source for each of the source art works associated with the digital sources used to create the derivative work.

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

A method and system for detecting change to a record in a file stored on an electronic token involves storing a change detection code (CDC) so that a change detection applet can calculate a current CDC for corresponding record(s), and compare the current CDC with the stored CDC to determine if data has changed. Any changes to records are registered by a registering element that provides a service feature, back-up of the file and/or synchronizes the file with other files stored remotely. One use of the method is to back-up phonebook records on USIM/SIM cards.
