Image server and method of controlling same
View Patent ↗An image registration server stores encryption keys of respective ones of a plurality of client terminals. Image data is encrypted by the image registration server using the encryption key corresponding to the client terminal to which the image data is applied. The encrypted image data is applied to the client terminal via a server. The client terminal has a decryption key stored within so that only a client terminal that is duly authorized can decrypt encrypted image data. Other client terminals that are not duly authorized cannot decode the image data. This makes it possible to prevent unlawful use of image data even if the image data has been intercepted.

a reading unit for reading data representing the printing history output from the image printing units;
a format conversion unit for converting the data representing the printing history read by said reading unit to data having a predetermined format; and
an aggregating unit for aggregating, for each of the plurality of printing units, the data which represents printing history and the format of which has been converted by said format conversion unit.
