The purpose of data protection scheme is to provide: 1. Piracy Protection: i.e. to prevent unauthorised use of data by encrypting the ENC information. 2. Selective Access: i.e. to restrict access to ENC information to only those cells that a customer has been licenced for. 3. Authentication: i.e to provide assurance that the ENC data has come from approved sources
