And a communication control unit 24 that controls communication with the ISP 4. The CPU 21, the main memory 22, the storage device 23, and the communication control unit 24 are connected to each other via the internal bus 210.

  The storage device 23 includes a distribution software holding unit 231 that holds software distributed from the ASP 3 and a screen information holding unit 232 that holds screen information transmitted from the user terminal 1 via the network 100. .

  4 and 5 are sequence charts showing the operation of the remote desktop system according to one embodiment of the present invention, and FIG. 6 is a diagram showing an initial setting screen of the user terminal 1 of FIG. The operation of the remote desktop system according to the embodiment of the present invention will be described with reference to FIGS. The operations of the user terminal 1 and the Internet cafe terminal 2 shown in FIGS. 4 and 5 are realized by the CPUs 11 and 21 executing the distribution software held in the control programs 12a and 22a and the distribution software holding units 131 and 231. The

  In the user terminal 1, a service application is made in advance to the Internet cafe terminal 2 [or Internet cafe server device (not shown)] (see a1 in FIG. 4).

  The Internet cafe terminal 2 instructs the ASP 3 to register data of user information applied from the user terminal 1 and to distribute server software (see a2 in FIG. 4). The ASP 3 performs the registration of user data to the server farm that has its own registration, and distributes the server software to the user terminal 1 (see a3 in FIG. 4).

  When the content of the application completion notification is confirmed (see a4 in FIG. 4), the user terminal 1 is distributed to the user terminal that the user wants to use as a remote desktop (in this case, the same terminal). When the server software is installed, necessary information such as an IP (Internet Protocol) address and an authentication password is registered on the initial setting screen (see FIG. 6) (see a5 in FIG. 4). ).

  The Internet cafe terminal 2 performs a test communication with the information registered at the time of service application to the user terminal 1 (see a6 in FIG. 4), and the initial setting is completed when it is confirmed that the test screen communication has been performed. It becomes.

  The user uses the Internet cafe terminal 2 at the Internet cafe outside the office, accesses the user terminal 1 that has been initially set via the network 100, and notifies the start of the remote desktop session (see b1 in FIG. 5).

  The user terminal 1 approves the start of the remote desktop session and notifies the Internet cafe terminal 2 of the start of the remote desktop session for transmitting the desktop screen (screen information) (see b2 in FIG. 5). The Internet cafe terminal 2 starts mutual communication with the user terminal 1 by notifying the user terminal 1 of the start approval of the remote desktop session (see b3 in FIG. 5).

  In this mutual communication, the Internet cafe terminal 2 receives screen information sent from the user terminal 1 and projects an image on the screen of the own terminal. The user can visually determine the information projected on the screen of the Internet cafe terminal 2 and operate the mouse and keyboard.

  Processing information by the mouse or keyboard is sent from the Internet cafe terminal 2 to the user terminal 1 via the network 100, and is processed inside the user terminal 1 based on the received processing information (see b5 in FIG. 5) and output. Start sending image information. This operation is continued while the user continues to receive services. While in service, these communications need to be encrypted.

  The ISP 4 basically performs an operation for the Internet cafe terminal 2 to connect to the network 100, but also performs a monitoring service for the remote desktop terminals (the user terminal 1 and the Internet cafe terminal 2) (see b6 in FIG. 5).

  When the user wants to end the service, the Internet cafe terminal 2 transmits a remote desktop session end notification to the user terminal 1 (see b7 in FIG. 5). Upon receiving an instruction to end the remote desktop session, the user terminal 1 ends the remote desktop session and notifies the Internet cafe terminal 2 of the end of the remote desktop session (see b8 in FIG. 5). When the Internet cafe terminal 2 receives the end notification of the remote desktop session, the Internet cafe terminal 2 ends the remote desktop session (see b9 in FIG. 5).

  As described above, according to the present embodiment, it is possible to easily perform operations such as access to the company's server and revision and reference of stored data on the PC outside the internet cafe.

  In addition, in this embodiment, since it is convenient to always draw out and create in-house information from a terminal placed on the go, there is an effect that a business user can be taken into the Internet cafe market.

  Furthermore, in this embodiment, the necessity of carrying a mobile PC with confidential information by a business user is reduced, and if an information leakage incident occurs, it leads to the loss of trust in the company, so that an effect in terms of security can be achieved. .

  The present invention can be provided to Internet cafe operators, hot spot operators, and the like. In addition, the present invention can apply the alliance to a wider range of fields by coordinating with ASP / ISP when performing application monitoring, system monitoring service for network management and security, etc. It is possible to develop into a larger business.
