A data processing system includes an event information generating apparatus including generation means that receives data collected from a plurality of terminals, generates event information from the data, and transmits the generated event information to a broker device. The event information generating apparatus includes transmission means that transmits, to a data hub node device corresponding to the event information generated by the generation means, among a plurality of data hub node devices that differ for each event information, data corresponding to the event information. The data processing system includes a data processing apparatus including acquisition means that acquires event information corresponding to a specific service from a broker device. The data processing apparatus includes processing means that acquires the data from a data hub node device that stores the data corresponding to the event information, to execute processing using the data.

An information communication apparatus, which aggregates data transmitted from a plurality of terminals and transmits the aggregated data to a reception side. The information communication apparatus includes: a determination means that operates in a first layer for determining an update size of a memory area used to hold the data transmitted from the plurality of terminals on a basis of information related to the data; and a setting means that sets a band of a network path of a second layer necessary for communicating with the reception side on a basis of the update size and an update rate of the data.

A terminal devicetransmits a certificate issue request including a communication ID thereof and a sub ID to a certificate issuing devicevia a NW(a first network). The certificate issuing deviceinquires of a communication ID (identifier) checking devicewhether or not the communication ID included in the certificate issue request is in use or not and inquires of a communication ID/sub ID checking devicewhether or not the communication ID and the sub ID are associated with each other. If both the check results are OK, the certificate issuing devicegenerates a certificate including the ID of the certificate issuing device, the communication ID, the sub ID and a validity period and transmits the certificate to the terminal device. In this way, a certificate with a short validity period can be issued only based on the access to the NWusing the communication ID and the sub ID.

Certificate authenticating method, certificate issuing device, and authentication device

A recipient identifier and communication condition information stored in a recipient-identifier storing unit are encrypted by an identifier-for-disclosure creating unit of a recipient terminal to create an identifier-for-disclosure. An identifier-for-disclosure notifying unit notifies a sender terminal of the identifier-for-disclosure. When a communication request using the identifier-for-disclosure is sent from the recipient terminal, a restoring unit of a relay system extracts the communication condition information from the identifier-for-disclosure. Only when communication conditions included in the communication condition information are satisfied, communication between the recipient terminal and the sender terminal is established.

Email system restoring recipient identifier based on identifier-for-disclosure for establishing communication between sender and recipient

When an alias mail having an alias address X as a destination is received from an originator terminal, an alias mail relay server restores a recipient address R and an alias address generation argument C, generates a reply destination address Y including the generation argument C restores and an originator address S, and replaces the destination and a transmission source with the recipient address R and Y to transfer the alias mail to a recipient terminal. On the other hand, when a reply mail is received from the recipient terminal, a remailer restored the originator address S and the generation argument C from Y, regenerates X from the generation argument C restored and the recipient address R, and replaces a destination and a transmission source with the originator address S and X to transfer the reply mail to the originator terminal.

Mail distribution system, mail distribution method, and mail distribution program

A file transfer system including a relay apparatus is provided in which the relay apparatus includes: an incoming file sending partwhich receives a file identifier I and a downloaded data amount O_R from a receive apparatusand a file storing partwhich stores the file identifier and file data and passes file data according to the file identifier and the downloaded data amount to the incoming file sending part. The file data F(O_R) is sent to the receive apparatus.
