Abstract:
Image data is transmitted from a client PC to an image formation apparatus. Upon printing, an external server conducts an authentication process. A certificate indicating that the user has been authenticated is held, with its validity period provided in the image formation apparatus. Within the validity period, the time-consuming authentication process with respect to the external server is skipped. This can reduce the burden of authentication while ensuring security, so that high productivity is guaranteed.
