Abstract: A system and a method initiate a data transmission from a first computer to at least a second computer or approve access to the data on a first computer by a second computer. The computers are interconnected through a network connection. The first computer is protected against access through the network connection by a firewall. Another communication connection, which the first computer does not use for transmitting data, is provided for initiating the access authorization to the first computer or the data transmission from the first computer to at least the second computer. A printing machine is provided with the system.

Abstract: A method for the remote maintenance of devices that include a computer by way of a remote maintenance computer. At least one protocol is used to exchange data between the local computer and the remote maintenance computer. The protocol adaptation level is provided which, prior to a data transfer process, evaluates the protocol for exchanging data between the computer and the remote maintenance computer in terms of the compatibility of the protocol with the upcoming data transfer process. If necessary, the protocol is adapted.

Abstract: A method for transmitting operating data of machines in the graphics industry is performed via a communications network that is accessible to the public and the operating data is transmitted to at least one management computer that can be reached via the public communications network. The operating data from the machine in the graphics industry is stored in encrypted form in at least one computer assigned to the machine, and the encrypted operating data is transmitted to the management computer via the communications network that is accessible to the public and is stored on the management computer.

Abstract: A method for improving the operation of machines or appliances having an associated machine computer and being connected to at least one further computer over a communication network, includes transmitting operating data and/or order data from the machine computer to the further computer through the communication network and storing the operating data and/or order data in the further computer. The further computer compares the performance of at least one machine with the performance of further machines, and the further computer calculates improved settings for at least one of the machines on the basis of the performance comparison and provides the settings for the purpose of setting the machine.

Abstract: A method for carrying out maintenance or service operations on machines, includes transmitting data for a maintenance or service requirement by the computer of the machine over a publicly accessible communications network to a management computer. The management computer checks the status of the machine through the computer of the machine for permissible authorizations. The corresponding service or maintenance operations are carried out on the basis of the authorization of the machine detected by the management computer. The service or maintenance requirement can also be reported by the computer of the machine over the publicly accessible communications network to the management computer, and the management computer can create a checklist for processing the required service and maintenance measures, on the basis of at least one error message received, and can transmit it to the computer of the machine. A system is also provided for carrying out the method.

Abstract: An electronic system provides secure and authorized access to data or a user interface on at least one first computer for operating machines from at least one second computer. The data or the user interface on the first computer can be accessed exclusively from the second computer, in that the second computer has an authorization device which stores the access data for personnel with access authorization, and in that access to the data or the user interface on the first computer is preceded by a display apparatus connected to the first computer showing a display which reveals the identified personnel with access authorization from the second computer.
