When SDMC was first proposed as a standard, the descriptions of how it worked noted that a personal identification, such as a credit card number, would be attached to a file to be downloaded. If that file were to be copied, the SDMC would look for a matching credit card number (i.e., the number of the user who presumably was charged a fee for the original download). If no matching credit card number were found, then the file could not be transferred, thereby protecting the copyright. I've never seen any description of the technical features, nor do I know if this is the total extent of the security provisions. Art
