| 1. A data processing system comprising:
a plurality of data processing devices; and
a storage device to which said plurality of data processing devices are connected,
wherein the data processing device comprises:
setting information storage means for storing setting information necessary for processing data; and
means for sending the setting information stored in the setting information storage means to the storage device, and
the storage device comprises:
classification storage means for storing the setting information sent from the data processing device in association with
a classification group in which the data processing device which sent the setting information is classified according to a
predetermined condition;
means for receiving a transmission request to send the setting information stored in said classification storage means to
one data processing device;
means for recognizing a predetermined condition in said one data processing device when said means receives the transmission
request;
means for selecting a setting information to be sent from the setting information stored in said classification storage means
on the basis of the recognized predetermined condition in said one data processing device, and sending the selected setting
information to said one data processing device;
means for receiving, from an external data processing device, protection function information showing strength of a data protection
function for protecting data to be processed by the data processing device;
means for classifying the external data processing device according to the strength of the data protection function as the
predetermined condition, based on the protection function information received by said means;
means for receiving, from an external data processing device, encrypted setting information produced by encrypting setting
information necessary for processing data in the data processing device;
means for storing the encrypted setting information received by said means;
means for sending the encrypted setting information stored in said means to the data processing device which sent the encrypted
setting information; and
means for prohibiting the encrypted setting information from being sent to a data processing device other than the data processing
device which sent the encrypted setting information.
