Method and system for reporting to a source user before communication begins communication means usable by both the source and a destination user. Operable communication means at each user's information terminal are stored in a list DB 2 in advance for each user. A selection device 1 receives a destination user designation from the source user who is requesting communication, and acquires the usable communication means of the destination user and the source user respectively from the list DB 2. There are also cases in which the selection device 1 acquires communication means usable by the source user from the selection device 1 or a user terminal 4. Next, the selection device 1 creates a candidate list describing communication means which both parties can use, and sends it from a WWW server, for example, to the source user terminal. Before communication begins, the candidate list is displayed at the source user terminal by a WWW browser, for example.

Messaging system and device for enabling users simultaneously and directly to send messages to numerous persons in cases where the users cannot connect directly to a chat system. A message is received by messaging device 1 from access device 2, which is a telephone set for example, and is stored in message database 3 as is without further processing. In addition to the message, messaging device 1 also receives a message destination designation from access device 2. Messaging device 1 reports a storing location for the message on an IRC, a URL for example, by sending a text message to the message destination. The IRC client notifies the user of the text message in real time. A user who views the text message makes a request to provider device 4 to provide the message using acquisition device 8. Provider device 4 accesses the message database, reads the message, and sends it to the acquisition device 8. Thereby, the message sent from access device 2 is reported as is to another user.

The present invention was made in order to provide a technology capable of safely ciphering compressed and encoded image data irrespective of lines or media and carrying out a correct decoding operation without any shifts in the frames of ciphered moving pictures. Further, so as to prevent giving any means of encoding from comparison of image ciphered data and so as to generate totally different ciphered image data from the same data compressed images, a processing is executed not on an ECB mode but on such modes as CBC, CFB, OFB or the like. Moreover, as an initial vector, information different for frames included in a header, that is, time information from the start of an image or a frame sequential number, is used. In this way, even if compressed images within adjacent frames are accidentally the same, totally different ciphered data can be obtained.

A software charging system includes a utilization permitting device for giving permission to use a software storing medium storing ciphered programs or data (software); and an authorization center capable of communicating with the utilization permitting device for setting a utilizable amount, totalling utilization amounts and charging a user. The utilization permitting device includes: a utilization permission processing part having a clock for obtaining date and time data, and having a date and time data storing unit for storing obtained date and time data until obtaining next data and time data; and a utilization amount managing part for calculating a software utilization amount of an end user. A software utilization amount is managed based on the number of days at the utilization permission processing part.

In this way, the tag access control system can improve a success rate of reading data from and writing data in a plurality of IC tags without lowering a moving velocity of articles.
摘要:
A notification is sent to a group of information terminals that conduct simultaneous communication by participating in a channel. The status change notification system includes a database DB and monitoring means 1. The DB is disposed outside the channel. The monitoring means 1 monitors an occurrence of a status change in the DB, and generates a notification of a status change when a status change occurs. At least one of the group of information terminals includes notifying means 3. The notifying means 3 receives a notification of status change from the monitoring means 1. The notifying means sends the notification to other of the group of information terminals to notify of the status change in a broadcasting manner.

A file protection system for protecting a file which is stored in a storage unit includes a storage position deciding unit for deciding a positional-information corresponding to an area in which information of the file is stored in the storage unit and an encryption unit for encrypting the information of the file in accordance with a predetermined algorithm using at least a part of the positional-information decided by the storage position deciding unit. Information obtained by the encryption unit is stored in the area identified by the positional-information in the storage unit. A file protection system is operable when information of a file which was encrypted as described above is read out from a storage unit. The file protection system includes a decryption unit for decrypting the encrypted information of the file which is read out from an area in the storage unit using information corresponding the area, an extracting unit for extracting the positional-information from information obtained by the decryption unit, and a determination unit for determining whether or not the positional-information extracted by the extracting unit is equal to corresponding positional-information which is at least a part of the information corresponding to the area from which the encrypted information of the file is read out. When the determination unit determines that two pieces of positional-information are not equal to each other, it is determined that the information obtained by the decryption unit does not include correct information of the file.
