A server distributes, to a mobile device, a catalog of available digital content and receives, from the mobile device, a request to download multiple digital content files based on the catalog. The server sends, to the mobile device, the multiple digital content files, where the each of the multiple digital content files includes access restrictions to prevent unauthorized rendering. The server receives, from the mobile device, a request to render one of the multiple digital content files on the mobile device and determines whether rendering of the one of the multiple digital content files on the mobile device is authorized. The server sends, to the mobile device, information to enable rendering of the one of the multiple digital content files if the mobile device is authorized and applies charges, to a user account associated with the mobile device, based on the sending the information to enable the rendering. |
