A service providing system is provided including a service providing device adapted to provide a service through a network and a device adapted to receive the service from the service providing device. The device includes a service request unit that requests the service providing device for a service, and a service implementation unit that implements a function of the device after receiving the service from the service providing device that is requested. The service providing device includes a service provision executing unit that provides the service to the device when the service providing device receives the request from the service request unit, and a function judging unit that judges whether the device is equipped with a function to receive the service provided by the service provision executing unit based on equipped function information that indicates functions for which the device is equipped.

A print data creation apparatus for creating print data in band units may comprise an obtaining device, a decompressed data creation device, a band determination device, a deletion device, a data range storage device, a data range specifying device, and a print data creation device. The obtaining device obtains compressed data of one or more image objects. The decompressed data creation device creates decompressed data by decompressing the compressed data of the one or more image objects in partial units. The band determination device determines, for each decompressed data created by the decompressed data creation device, to which band the decompressed data is necessary. The deletion device deletes the decompressed data that the band has been determined by the band determination device. The data range storage device stores, based on information determined by the band determination device, for each band, an association of the band and a data range of the compressed data that is necessary for creating print data corresponding to the band. The data range specifying device specifies, based on information stored in the data range storage device, a data range of compressed data associated with a band of which print data is to be created. The print data creation device creates print data from compressed data within the data range specified by the data range specifying device.

A communication system includes a server and at least one client. The server includes a first communication unit that performs first communication with each client based on a first protocol, a second communication unit that performs second communication with each client based on a second protocol, an information receiving unit that receives first information with the first communication unit, an information extracting unit that extracts second information, a judging unit that judges whether the second communication is feasible based on the first and second information, and a command sending unit that sends a command for issuing a request for establishing the second communication when the second communication is feasible. Each client includes an information sending unit that sends the first information, a command receiving unit that receives the command, and a request sending unit that issues the request to the first communication unit in response to the command.

A network device is provided. The network device includes a communicating unit, which is adapted to communicate with an information processing device via a network to make an operational setting for encrypted communication to be established between the network device and the information processing device, a searching packet receiving unit to receive a searching packet to search for network devices transmitted from the information processing device, a judging unit to judge status of the operational setting for the encrypted communication, a reply packet generating unit to generate a reply packet including information regarding the result of the judgment made by the judging unit in response to the searching packet which is received by the searching packet receiving unit, and a reply packet transmitting unit to transmits the reply packet generated by the reply packet generating unit to the information processing device via the network.
摘要:
There is provided a communication system in which a network device and an information processing device are communicatably connected to each other through a network. The network device comprises a certificate providing unit to transmit an electronic certificate to the information processing device through the network; and a printing unit configured to print an image of a public key corresponding to the electronic certificate. The information processing device comprises: a certificate reception unit to receive the electronic certificate from the certificate providing unit through the network; an image output unit to generate and output an image of the public key described in the received electronic certificate; and an installation unit configured to install the electronic certificate onto the information processing device in response to a fact that the generated image of the public key is output by the image output unit and a command for installation of an electronic certificate is received.
摘要:
An apparatus for use in implementing encrypted communications using a digital certificate is disclosed. The apparatus is configured to include a memory storing therein the digital certificate; and a selective-transmit controller, upon receipt of a request from a requester for the encrypted communications using the digital certificate, determining whether or not the digital certificate is valid, transmitting the digital certificate to the requestor if the digital certificate is valid, and not transmitting the digital certificate to the requester if the digital certificate is not valid.

There is provided a management apparatus, which comprises a transmission condition judgment unit which refers to a target digital certificate and judges whether a predetermined transmission condition is satisfied based on a period of validity written in the target digital certificate, a mail generating unit which generates an e-mail provided with link information to a web page where updating operation on the target digital certificate is acceptable if the predetermined transmission condition is judged as satisfied by the transmission condition judgment unit, a destination setting unit which sets an destination e-mail address of the e-mail generated by the mail generating unit, and a mail transmission unit which transmits the e-mail generated by the mail generating unit to the destination e-mail address set by the destination setting unit.
摘要:
A network communication system which can shorten processing time by selecting an adequate encryption method based on an encryption processing speed is provided. In the communication process, the client device determines whether the server device is in the same LAN or in WAN and whether the watermark such as “Confidential” is added to data. Then, based on these determination results, the client device extracts encryption methods from common key methods usable, and makes a list of encryption method candidates. The server device selects a common key method to be used to encrypt communication data from the notified list based on the communication speed and the encryption strength. The client device encrypts the communication data using the agreed common key method, and sends the encrypted data to the server device. Then, the server device decrypts the received encrypted data using the relevant common key method.
