An information processing apparatus for processing encrypted data input as a byte stream with dynamically changing decryption keys includes the following elements. An encrypted data receiving section receives encrypted data input as a byte stream, identifies a range of data that is decrypted using an identical key as a unit of decryption, extracts information necessary for decryption from the byte stream, and outputs encrypted data sets in which the extracted information is added to segments of the encrypted data. An encrypted data decrypting section sequentially decrypts the encrypted data by queuing the encrypted data sets while distributing the encrypted data sets to generate plaintext data. A plaintext processing section processes the generated plaintext data.

When a transmission history such as a job is displayed, specific information is quickly retrieved from the transmission history by displaying an image included in the transmission history as a thumbnail. An information processing system includes an MFP that includes a function of transmitting image data and a client PC that instructs transmission of the image data to the MFP and the MFP and the client PC are connected to each other through a network. The client PC includes an HDD that stores therein, for each transmission job, a transmission history that includes image data that the client PC instructs the MFP to transmit, a history data creating portion that creates a thumbnail image by converting the image data of the stored transmission history into a thumbnail, and a display data control portion that causes the thumbnail image created by the history data creating portion to be displayed.

The present invention relates to a network system allowing easy communications with another apparatus via NAPT, a communication method, information processing apparatus and method, and a program. A local communication apparatus 11 acquires a service providing packet from an apparatus service providing apparatus 51 via a port 342-1 of a relay apparatus 12, acquires a service providing packet from an apparatus service providing apparatus 52 via a port 342-2 of the relay apparatus 12, calculates a difference value between two pieces of global address information contained in the service providing packets, and predicts that a port 342-3 is the port to be used for the next communication. The present invention can be applied to an instant message service system.

It is made possible to update software appropriately. When additional software is installed, update management data for the additional software is generated. When the update management data for the additional software is attached to the additional software in advance, that data is used. If the update management data is not attached, cycles for confirming the presence of updates and the like are determined based on the nature of the software, and the update management data is thus generated. Then, the generated update management data is set in an update management table. The presence of software updates is checked for based on the cycles for confirming the presence of updates in the update management table.
摘要:
A server computer executes a program including: the step of receiving and storing install information, when a universal printer driver is installed in a client computer; the step of simultaneous broadcast transmission, to search for MFPs on a network; the step of storing MFP information based on responses to the simultaneous broadcast from the MFPs; and the step of storing, when a request for limiting use of MFPs is issued, information of MFPs of which use is limited. When the universal printer driver is activated in the client computer, printing is done by a usable MFP, in accordance with the information of MFPs of which use is limited, stored in the server.

In order to realize NAT traversal communication at low cost and without fail, local communication terminals connected as subordinates of a first router having a UPnP™ function obtain an IP address and a port number, both to be converted by a NAT function of the first router, on the basis of a UPnP™ protocol to register them in a relay server as exchange information for the NAT traversal. Local communication terminals connected as subordinates of a second router without the UPnP™ function specify an IP address to be converted by the NAT function of the second router on the basis of a packet obtained from a STUN server and estimate a port number to be converted by the NAT function of the second router to register them in the relay server as the exchange information for the NAT traversal. The present invention may be applied to a personal computer.
摘要:
An image processing apparatus, a print control method, and a print control program are provided that are capable of printing after changing print setting by an easy operation for a application program in operating. Together with two windows of document creating programs which are operating, a gadget indicating calendar information and a print setting gadget are displayed as gadget programs in an area of the right side of a desktop screen of a PC. When a print setting button of the print setting gadget is selected, the print setting condition corresponding to the selected button and the application program in operating are stored, and when a print request is made from the application program, the setting value of a printer driver is changed for printing.
