Description

BACKGROUND OF THE INVENTION [0001] BACKGROUND OF THE INVENTION This invention relates to connection restriction method for limiting illegal connection terminal in the information processing system. 2. Description of the Related Art Generally, when using an information processing system, for example, an information retrieval system, a user enters a predetermined contract with an information provider (server) as a customer (client). Has become. According to this contract, the model and number of terminals that can use the information search system are specified, and information search using terminals other than those specified is not permitted. [0003] However, in such a system (client-server system),
Even if a client or a person who knows the password can connect to the network with a terminal exceeding the contracted number or a terminal other than the contracted model and search for information, this cannot be detected on the server side. There were challenges. Accordingly, it is an object of the present invention to provide a connection restriction method capable of restricting use of a terminal out of a contract. In order to achieve the above object, the present invention provides an information processing system in which a server device executes information processing corresponding to a request from a client terminal via a network. The terminal includes a storage device storing model information on its own model, and the server-side device stores contract model information indicating the number of contract connections with the terminal corresponding to each model information. Device, the terminal device transmits its own model information to the server device together with a connection request for requesting execution of information processing, and the server device transmits the connection request and model information from the terminal device. when receiving, the model information against the said contract model information, current number of connected <br/> terminal corresponding to the model information whether the contract connected units or less Constant, and executes the processing if compatible, the connection restriction method of a terminal in an information processing system, characterized in that to reject the information if not compatible. According to the present invention, the server-side device obligates the client-side terminal to transmit the model information, but the server-side device uses the received model information to transmit the terminal device of the transmission source. Can be immediately determined as to whether or not the information is illegal, whereby information processing such as connection to a search line can be rejected. This means, for example, that the person requesting a connection to the search line is a party to the contract,
A connection restricting effect is obtained in which information retrieval from the terminal violating the contract is excluded. In addition, it becomes easier to handle and manage the server side when the number of terminals is increased or decreased due to the renewal of the contract. An embodiment of the present invention will be described with reference to the drawings. As shown in FIG. 1, a client-side terminal 10 has a storage device 11 in which information on the model is stored.
It has. On the other hand, the information source device 20 on the server side determines whether or not it is possible to connect to the storage device 21 which stores information such as the model of the terminal based on the contract with the client, the number of connected models and the current number of connected models, and the search line. A connection determination device 22 for determination is provided. The information source device 20 on the server side and the terminal device 10 on the client side are mutually connected by a network 30. [0009] It and exchanges signals with the client side of the terminal and the server-side apparatus will be described with reference to FIGS. 1 and 2 as follows. When the client executes information retrieval using the terminal device 10, first, model information stored in the storage device 11 is read in step (C1) of FIG. In step (C2), a signal for requesting connection to the search line is transmitted to the server-side information source device 20 together with the model information. In the step (S1), the server receives a transmission signal from the client. In step (S2), information relating to the model of the contract with the client, the number of model-connected contracts, and the current number of connected models is read from its own storage device 21, and in step (S3), the connection determination device 22 sends the information to the search line. It is determined whether or not the connection is permitted. In this determination, it is determined whether or not the model information transmitted from the client side does not violate the contract contents, based on various information read from the storage device 21. Since the processing is performed by a logic circuit such as a CPU, the processing is completed in a short time. If the result of the determination is not the same model as the contract model, or if the same model exceeds the number of connected models, the connection NG information is transmitted to the client side.
Do not connect to the search line. However, if the same model as the contract model and the number of contracted connections of the same model is larger than the current number of connected models of the same model, it is within the contracted number frame, so connection OK is sent to the client side to permit connection. In step (S4), "1" is added to the current number of connected storage devices 21 of the client, and a processing request from the client is waited. In step (C3), the client receives the result of the connection request from the server, and terminates its own processing if the connection is unacceptable. In step (S5), the server performs processing for the processing request received from the client, and in step (S6), transmits the processing result to the client.
If the processing request from the client is a disconnection request, “1” is subtracted from the current number of connected models of the storage device 21 of the client in step (S7), and the connection with the client is terminated. FIG. 3 shows a specific example of model information used in this embodiment.
FIG. 4 shows specific examples of the contract model, the number of contracted connections for each model of the client, and the current number of connected models for each model. The number such as “003” is defined and assigned in advance for each model. It is assumed that all of these numbers are encoded so that only a specific person can change them. As described above, according to the present invention, in a data processing system in which a server device executes a data process corresponding to a request from a client terminal via a network, the terminal is self-contained. The server-side device comprises a storage device storing contract model information indicating the number of contracted connections with the terminal corresponding to each of the model information, and The device transmits its model information to the server-side device together with a connection request for requesting execution of information processing, and when the server-side device receives the connection request and the model information from the terminal device, the information collated with the contract model information, current number of connected terminal corresponding to the type information
It is determined whether or not the number is equal to or less than the contracted number of connections, the information processing is executed if conformity, the information processing system is characterized by rejecting the information processing if not suitable, By doing so, for example, it is possible to immediately determine whether the client-side terminal that has requested the server-side device to connect to the search line is proper or illegal, and if the terminal is illegal, the connection is unilateral. Can be rejected. In addition, it is possible to streamline the management task on the server side for the increase / decrease or update of terminals.
