DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a software product having processing information to be executed by an arbitrary processing apparatus. It relates to effective technology for providing protection.

[0002]

2. Description of the Related Art In general, a library for storing a plurality of routine processing information necessary for creating a program or executing the program is known. The user can perform efficient work by using the above library when creating or executing a program. Recently, an information processing system in which a plurality of user terminals, a host computer, a server dedicated to managing a library, and the like are connected in a network format has become widespread. According to this information processing system, a single library can be used by a plurality of user terminals, and simplification of the system configuration, cost reduction, and efficient use of the library can be realized. In this case, when the server receives a library use request from the user,
It has a function of reading processing information required by the user from the library and returning it to the user.

Further, there is known a technology in which a plurality of information processing systems are connected by a communication line so that a user terminal of one information processing system can access a library of the other information processing system. If this is the case, the user can use a library at a remote location. However, there is a problem that the contents of the library belonging to one information processing system can be copied to the library of the other information processing system, and the library as a product cannot be sufficiently protected.

On the other hand, in the case of a software product composed of a plurality of mutually related processing information, the following method is employed to protect the software product.

When a software product is sold, a server for registering the software product is specified, and at the same time, a management means for specifying the number of users who can use the software product and managing the number of users is provided. Specifically, the vendor that sells the software product registers the software ID for specifying each software product and the server ID of the server to which the software product is to be registered in the management unit as a pair. Further, the software product registers processing information that is always read at the start of activation and activation information for activating the management unit, and creates an interface for calling the activation information in the processing information.

When using the software product,
The server inevitably reads the processing information, and reads the activation information by an interface created in the processing information. Then, according to the start information, the server ID of the own server and the software ID of the software product
Is notified to the management means, and the management means is activated.

The management means determines whether or not the program ID and the server ID are registered as a pair, and at the same time, detects the number of users accessing the software product at the present time and detects the number of users including the user. Check the number against the number of available users.

Here, the program ID and the server ID
Are registered as a pair, and when the number of users including the number of users is equal to or less than the number of available users, the use request of the user is permitted. This method prevents software products registered in the server of one information processing system from being copied to the server of the other information processing system.

As a method for preventing copying of a library,
Although it is conceivable to apply the software product protection method described above, if the library stores processing information that is not related to each other, that is, is independently activated independently,
There is no processing information that is always started when the library is started to be used, and the management unit cannot be started. As a first method for solving this, it is conceivable to add software that is activated by a command unified in the library (see FIG. 12). In this case, the server first reads the software. Then, the management unit is started according to the software.

As a second method, a method is conceivable in which an area for storing unified information is provided for each piece of processing information of the library, and at the same time activation information of the management means is created for each piece of processing information (see FIG. 13). ). In this case, the server
When any of the processing information is read, the management unit is activated by the activation information created in the processing information. Then, information indicating that the management means has been started is stored in the area. Thus, when the same user requests the use of other processing information, the server can read the processing information by referring to the area without activating the management unit.

[0011]

However, according to the first method described above, when the user directly accesses the library, the management means cannot be activated, and the library cannot be protected. is there.

According to the second method described above, it is necessary to add a name indicating the unified information area to the processing information, and when the same name is used in the user terminal in the user terminal, May destroy this unified information area. Here, it is conceivable to present the name to the user in advance, but in this case, the user has to search for the program used in the user terminal, and the operation is complicated.

[0013] The present invention has been made in view of the above problems, and it is an object of the present invention to provide a technique capable of protecting a library itself without imposing a burden on a user.

[0014]

The present invention has been made as follows to solve the above-mentioned problems. This will be described based on the principle diagram of FIG.

The information processing system according to the present invention comprises a library 2 for storing a plurality of routine processing information 31, a plurality of user terminals 1, a library registration unit 3, and a management unit 4.

The above-mentioned library registration means 3 stores the library 2 and, when a use request of the library 2 is received from an arbitrary user terminal 1, the processing information 31 to be requested.
Has the function of reading out and transmitting it to the user terminal 1.

The management means 4 determines the validity of the library registration means 3 and the library 2 to which the use request is applied,
It has a function of determining whether to permit the use request. More specifically, the library 2 adds start information 30 for starting the management unit 4 and, at the same time, adds call information for calling the start information 30 to each process information 31.

Further, the library registration means 3 may include a library storage section 3a and a read control section 3b. The library storage section 3a stores the library 2 described above.

The read control unit 3b includes a library storage unit 3a
Has a function of reading arbitrary processing information from the processing information, a function of calling the start information 30 based on the call information 32 from the processed information, and a function of issuing a start instruction to the management unit 4 based on the start information 30.

[0020]

In the information processing system according to the present invention, the library 2 is transmitted from any user terminal 1 to the library registration means 3.
Issue a use request for

In the library registration means 3, the user terminal 1
Is determined, and the activation information 30 is called based on the call information 32 stored in the processing information 31.

Next, the library registration unit 3 notifies the management unit 4 of a start command based on the start information 30. In the present invention, a library registration unit 3 in which each library 2 is to be stored is specified, and the management unit 4 determines whether the library registration unit 3 and the library 2 are valid, that is, the library 2 is a library It is determined whether or not it is registered in the means 3. When registered in the library registration unit 3 as specified, the management unit 4 notifies the library registration unit 3 that the use request is permitted. Upon receiving this notification, the library registration unit 3 reads the processing information requested by the user terminal 1 and transmits the processing information to the user terminal 1.

Further, according to the present invention, the library 2 and the library registration means 3 for storing the library 2 are defined.
The number of user terminals that can simultaneously access the library 2 may be defined.

In this case, when the management means 4 receives a start command from the library registration means 3, the library registration means 3 determines whether or not the specified library 2 has been registered, and at the same time, And compares the number of user terminals used in the above with the specified number of user terminals.

The management means 4 registers the library 2 in accordance with the regulation by the library registration means 3 and only when the current number of user terminals is less than the prescribed number of user terminals,
Permit use request.

When transmitting the start command to the management means 4, the read control section 3b sets the start command, registration means identification information for specifying the own library registration means, and the library registered in the own library registration means. 2 may be transmitted. in this case,
The management means 4 includes an identification information registration table 4b, a counter 4c, and a comparison / determination unit 4a.

The above-mentioned identification information registration table 4b includes, for each library identification information for specifying each library 2, registration means identification information for specifying the library registration means 3 in which each library 2 is to be registered, and the number of available users. Is stored.

The counter 4c counts the number of user terminals currently using the individual libraries 2. The comparison / determination unit 4a refers to the identification information registration table 4b based on the library identification information received from the read control unit 3b, reads the registration unit identification information and the number of available users corresponding to the library identification information, and reads the registration unit identification information. The information and the registration unit identification information received from the read control unit 3b are compared. Further, the count value of the counter and the number of available users are compared.

Here, the comparison / determination unit 4a permits the use request when the registration unit identification information matches and the count value of the counter is less than the number of available users. Further, each user terminal 1 may transmit a use request for the library 2 and call information 32 for calling the activation information 30 to the library registration means. In this case, the read control unit 3b can call the start information 30 based on the call information 32 and transmit a start instruction to the management unit 4 based on the start information 30. That is, it is possible to receive the permission of the use request before reading the processing information. In this case, in the start information 30, start history information indicating whether the management unit 4 has been started based on the call information 32 from the user terminal 1 is registered. This allows
When reading the processing information 31 requested by the user terminal 1, the read control unit 3b accesses the activation information 30 based on the call information 32 of the processing information 31, and refers to the activation history information. Thus, the call information 32 from the user terminal 1
If the management means has already been started, the processing information 31 requested by the user terminal 1 is transmitted to the user terminal 1.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Specific embodiments of the present invention will be described below.

[0031]

First Embodiment FIG. 2 is a block diagram showing the overall configuration of an information processing system according to the first embodiment. In the figure, the information processing system connects three user terminals (A) 7a, user terminals (B) 7b, user terminals (C) 7c, a library storage server 5, a library management server 6, and a communication management server 10 to a communication line. 11 are connected.

The library management server 6 stores the library 5
a is installed, and when a use request for processing information is received from an arbitrary user terminal 7, the processing information requested by the user is read from the library 5 a, and is read out from the user terminal 7.
Send to This specific description will be described later. When installing the library 5a, a server ID for specifying the library management server 6 and a library ID for specifying the library 5a are added to the library management server 6.

The library management server 6 determines whether or not an arbitrary library 5a is installed in a predetermined server and, at the same time, limits the number of users who can be used when receiving a use request from a plurality of user terminals 7 at the same time. Is what you do. This specific description will be described later.

The communication management server 10 manages the setting and cancellation of a communication path with another information processing system via a network. That is, when a communication request to a user terminal of another information processing system is received from the user terminal 7 belonging to the information processing system, a communication path setting request to the communication destination information processing system is transmitted to the network. When a communication request is received from another information processing system, the user terminal 7 or the server that is the communication destination is determined,
Set the communication path.

FIG. 3 is a block diagram showing the internal configuration of the library storage server 5 according to the first embodiment. In the figure,
The library storage server 5 includes a read control unit 5b and a library 5a.

The library 5a stores n pieces of processing information (1)
処理 process information (n) and activation information 50 are stored. The processing information (1) to the processing information (n) are programs indicating typical processing to be executed by the processor. Here, the processing information (1) to processing information (n) are independent programs that are not related to each other, and do not have a command for calling other processing information from arbitrary processing information. Further, a call command of the above-mentioned activation information 50 is registered in each processing information (n). This specific description will be described later.

The start information 50 is stored in the library management server 6
Is a function program including an execution instruction for activating the library management server 6 and an activation history of the library management server 6. The library management server start history is normally set to “0”,
This flag is set to “1” when the library management server 6 is started, and is reset to “0” when reading of the processing information is completed. For example, when a request to use two or more pieces of processing information is received from a single user terminal 7 at the same time, the library management server 6 is activated when the first processing information is read. Then, when the use request from the user terminal 7 is permitted, the flag is set to “1”.
Thus, when reading the subsequent processing information, the flag may be referred to, and if "1" is set, it is not necessary to repeatedly start the library management server 6. still,
This flag is reset to “0” when all the processing information requested from the user terminal 7 is read. This specific description will be described later.

First, the reading control unit 5 b
The function has a function of reading out the processing information requested by the user terminal 7 from a, and transmitting this processing information to the user terminal via a communication line. Secondly, it has a function of reading out the start information 50 based on the call command of the processing information and transmitting a start instruction to the library management server 6 based on the start information 50.

In the second function, the read control unit 5
b refers to a flag registered in the activation information 50. If “0” is set in the flag, a start command is issued to the library management server 6 based on the start information 50. On the other hand, if the flag is set to “1”, the activation information is not issued to the library management server 6 and the processing information requested by the user terminal 7 is transmitted to the user terminal 7.

Here, the start information 50 and the processing information (n)
4 is shown in FIG. The processing information and the activation information 50 in the first embodiment are programs in which routine processing is converted into a subroutine and translated into a machine language.

In the figure, the processing information (1) contains "SUB
(1) ", processing information (2) is given" SUB (2) "... processing information (n) is given the name" SUB (n) ", and startup information is given the name" SUB (X) ". Is given.

Each processing information includes "SUB".
(CALL SUB)
(X) ". In the start information 50, a flag indicating the start history of the library management server 6 and an operation command of the library management server 6 are created.

Here, the read control unit 5b is connected to the user terminal 7
Access the processing information (n) requested by the user, and call information, that is, "CALL SUB (X)" from the processing information (n).
Recognize. Then, the call command “CALL S
The activation information 50 is called based on “UB (X)”. The read control unit 5b refers to the flag in “SUB (X)” and, when the value of the flag is “0”, issues a start command to the library management server 6 according to the operation command, the server ID of the library storage server 5, and The library ID of the library 5a is transmitted.

When the permission information of the use request is received from the library management server 6, the flag is set to "
The processing information requested by the user terminal 7 is read from the library 5a and transmitted to the user terminal 7.

Further, when the use of the user terminal is completed, the reading control unit 5b sets the flag of the activation information 50 to “
On the other hand, when a request to use a plurality of pieces of processing information is received from the user terminal, that is, when a use request is received in addition to the processing information, the same operation as described above is performed. However, in this case, since the flag of the activation information is set to “1”, the reading control unit 5b does not activate the library management server 6 and
The processing information requested by the user terminal 7 is transmitted.

FIG. 5 is a block diagram showing the internal configuration of the library management server 6. The library management server 6 according to the first embodiment includes a determination unit 6c, an ID registration table 6
a, and a counter 6b.

When the library 5a is installed in the library storage server 5, the ID registration table 6a registers the library 5a and the library storage server 5 to be installed in a specific number server ID and a library ID, respectively. The number of users who can simultaneously access the library 5a is registered. (See FIG. 6).

The counter 6b counts the number of user terminals using the library 5a. Judgment unit 6
When the library ID of the library 5a requested by the user and the server ID of the library storage server 5 storing the library 5a requested by the user are received from the library storage server 5, c is based on the library ID. Access the ID registration table 6a. Then, the library ID is obtained from the ID registration table 6a.
Is recognized and the number of available users. Here, the determination unit 6c checks the server ID read from the ID registration table 6a against the server ID received from the library storage server 5, and simultaneously determines the number of available users read from the ID registration table 6a and the counter 6b. Is compared with the count value.

When the two server IDs match and the count value is less than the number of available users, the determination section 6c permits the use request. Next, an operation process of the library storage server 5 according to the first embodiment will be described with reference to a flowchart of FIG.

When the library storage server 5 receives a use request for the library 5a from an arbitrary user terminal 7 (step 701), the read control unit 5b determines the processing information to be subjected to the use request (step 701). 702).

Here, the read control unit 5b accesses the processing information (step 703) and sets the calling command (CA
The startup information is called in accordance with the LL command (step 704).

The read control unit 5b refers to the flag registered in the activation information 50, and determines whether or not the value of this flag is "0" (Step 705). When the value of the flag is “0”, a start command to the library management server 6, the server ID of the library storage server 5, and the library Library I of 5a
And D (step 706).

Thereafter, the system waits for a response from the library management server 6, and upon receiving the response from the library management server 6 (step 707), recognizes whether or not the use request from the user terminal 7 has been permitted (step 707). Step 70
8).

Here, when the permission information of the use request is received, the read control unit 5b sets the flag of the activation information from "0" to "1" (step 709).
Next, the reading control unit 5b reads the processing information targeted for the use request from the library 5a and transmits the processing information to the user terminal 7 (Step 710).

If a request to use a plurality of pieces of processing information has been received from the user terminal 7 (step 71).
1) The read control unit 5b determines whether or not the read processing has been completed for all the processing information of the use request target (Step 712).

Here, when the processing information of the use request remains, the above-described processing of step 702 and subsequent steps are repeated. However, in this case, the flag of the call information is "
1 ”, the processing information is read and transmitted without activating the library management server 6. On the other hand, when the reading processing has been completed for all the processing information targeted for the use request, the reading control unit 5b Start information flag "1"
Is reset to "0" (step 713). In step 708, if the use request is not permitted, the process is terminated at this point (a message indicating that the library cannot be used is sent to the user terminal). May be transmitted).

In step 711, when a request to use a single piece of processing information is received from the user terminal 7, the read control unit 5b changes the flag of the activation information from "1" to "0".
Is reset (step 713), and the process ends.

Next, an operation process of the library management server 6 according to the first embodiment will be described with reference to a flowchart of FIG. The library management server 6 receives the library ID and the server ID from the library storage server 5 (Step 801), and the determining unit 6c accesses the ID registration table 6a based on the library ID (Step 802). Then, the server ID and the number of available users corresponding to the library ID are read (step 803).

Here, the determination unit 6c determines the server ID received from the library storage server 5 and the ID registration table 6a.
Then, it is determined whether or not they match (step 804).

If the two server IDs match, the determination unit 6c compares the number of available users read from the ID registration table 6a with the counter value of the counter 6b, and determines that the available It is determined whether it is less than the number. That is, it is determined whether or not the value obtained by incrementing the current count value by one is equal to or less than the number of available users (step 805).

Here, the number of available users is counted by the counter 6b.
If it is larger than the count value, the determination unit 6c notifies the library storage server 5 that the use request is permitted (step 6), and increments the value of the counter 6b by one.

On the other hand, if both server IDs do not match in step 804, and if the number of available users and the counter value are the same in step 805,
The determination unit 6c notifies the library storage server 5 that the use request is not permitted (step 807).

As described above, according to the first embodiment, the user terminal 7
, The library management server 6 can be automatically started by directly accessing the library 5a and reading processing information to be used.

When the user terminal 7 accesses a library of another information processing system and the user terminal 7 attempts to copy the library to the library storage server 5, the determination unit 6c determines the library of the library. Access the ID registration table 6a based on the ID. Then, it is determined whether or not the library ID is registered. The library ID is in the case of unregistered, and notifies the user terminal 7, to kill the replication.

On the other hand, if the library ID is registered in the ID registration table 6a,
The server ID registered as a pair with D is read, and the server ID of the library storage server 5 of the information processing system is read.
And the user terminal 7 is informed of the mismatch, and the copying process is forcibly terminated. As a result, the productivity of the library can be protected.

[0066]

Second Embodiment In the information processing system according to the second embodiment, two types of start information for starting the library management server 6 are created in the start information 50. Then, a call command for one of the activation information is created in each processing information of the library, and a call command for the other activation information is created in a user program to be processed in the user terminal.
Other configurations are the same as those of the first embodiment, and the description is omitted.

FIG. 9 shows a specific example of the user program, the processing information, and the start information in the second embodiment. In the figure, a flag indicating the activation history of the library management server 6 and an operation command of the library management server 6 are created in the activation information “SUB (X)”.

On the other hand, in the activation information “SUB (Y)”, a flag indicating the activation history of the library management server 6 and an operation command of the library management server 6 are created. And
"SUB (1)" for processing information (1), "SUB (2)" for processing information (2) ... "SUB" for processing information (n)
(N) ”, and the two pieces of activation information each have“ S
UB (X) ”and“ SUB (Y) ”. Further, a command “CALL SUB (X)” for calling the activation information “SUB (X)” is created for each piece of processing information.

The user program “MAIN” includes a command “CA” for calling the activation information “SUB (Y)”.
LL SUB (Y) ". Here the user terminal 7
Then, when the user program “MAIN” is executed, the call command “CALL SUB (Y)” is read and transmitted to the library storage server 5.

In the library storage server 5, the read control unit 5b sends the call command “CALL SUB (Y)”
The activation information “SUB (Y)” is called based on (see FIG. 3). Then, according to the operation command of the start information [SUB (Y)], the start command, the library ID of the library 5a, and the server ID of the library storage server 5 can be notified to the library management server 6.

Here, upon receiving from the library management server 6 that the use request is permitted, the read control unit 5b
Sets the flag of the activation information “SUB (X)” and the flag of the activation information “SUB (Y)” from “0” to “1”.

Next, the user terminal 7 continues the execution of the user program and calls the processing information call command “CALL S”.
UB (1) ", and notifies the library storage server 5 of a use request for the processing information (1). In the library storage server 5, the read control unit 5b accesses the processing information (1) and recognizes the call command “CALL SUB (X)”. Then, the read control unit 5b responds to the call command “CALL SUB (X)” by using the activation information “SUB”.
(X) ". Here, referring to the flag, "1"
Or “0”. Here, since the flag is set to "1", the call control unit 5b does not read a lower operation command. That is, the processing information (1) is read out and transmitted to the user terminal 7 without operating the library management server 6.

The operation process of the library storage server 5 according to the second embodiment will be described below with reference to the flowcharts of FIGS. FIG. 10 shows the activation information “SUB
(Y) is a flowchart showing an operation process of the library storage server 5 at the time of startup.

In the figure, the library storage server 5
Is the CA of the activation information "SUB (Y)" from the user terminal 7.
The read control unit 5b receives the LL command (step 1001), and starts information “S” in accordance with the CALL command.
UB (Y) "(step 1002). Here, it is determined whether or not the flag is “0” by referring to the flag of the activation information “SUB (Y)” (step 100).
3).

Here, when the flag is reset to "0", the library ID of the library 5a is set according to the operation command of the start information "SUB (Y)".
And the server ID of the library storage server 5 is transmitted to the library management server 6 (step 1004). Thereafter, it waits for a response from the library management server 6, and when it receives a response from the library management server 6 (step 10).
05), it is determined whether or not the use request of the user terminal 7 is permitted (step 1006). If the use request is permitted, the activation information “SUB (X)” and the activation information “SUB” are determined.
(Y) ": Both flags are set from" 0 "to" 1 "(step 1007). Thereafter, the call control unit 5b waits for the call of the activation information “SUB (X)”.

On the other hand, in step 1003 described above,
If the flag is set to “1”, “SUB
(X) "(step 1008). In step 1006 described above, when the permission of the use request is received, the fact that the use request is not permitted is transmitted to the user terminal 7.

FIG. 11 is a flowchart showing the operation process of the library storage server 5 when the activation information “SUB (X)” is activated. In the figure, when a library storage server 5 receives a use request for a library 5a from an arbitrary user terminal 7 (step 1101), the read control unit 5b
Determines the processing information targeted for the use request (step 1102).

Here, the read control unit 5b accesses the processing information (step 1103), and calls the call command (C
ALL command) and start information "SUB (X)"
Is called (step 1104).

The read control unit 5b sets the start information “SUB
(X) ", it is determined whether or not the value of this flag is" 0 "(step 110).
5). When the value of the flag is “0”, a start command is issued to the library management server 6 in accordance with the operation command of the library management server 6 registered in the start information “SUB (X)”, Server ID
And the library ID of the library 5a are transmitted (step 1106).

Thereafter, the system waits for a response from the library management server 6, and upon receiving a response from the library management server 6 (step 1107), recognizes whether or not the use request from the user terminal 7 has been permitted (step 1107). Step 110
8).

Here, when the permission information of the use request is received, the read control unit 5b starts the activation information “SUB”.
(X) "and the activation information" SUB (Y) "
The value is set from "0" to "1" (step 1109) Next, the read control unit 5b reads the processing information targeted for the use request from the library 5a and transmits it to the user terminal 7 (step 1110).

If a request for using a plurality of pieces of processing information has been received from the user terminal 7 (step 111).
1) The read control unit 5b determines whether or not the read processing has been completed for all the processing information of the use request target (step 1112).

Here, if the processing information of the use request remains, the above-described processing of step 1103 and subsequent steps are repeated. However, in this case, the flag of the call information is "
1 ”, the processing information is read and transmitted without activating the library management server 6. On the other hand, when the reading processing has been completed for all the processing information targeted for the use request, the reading control unit 5b Startup information "SUB (X)"
And the flag of the activation information “SUB (Y)” is changed from “1” to “1”.
In step 1105, if the flag is "1", that is, if the library management server 6 has been activated by the activation information "SUB (Y)", the read control unit 5b , User terminal 7
And reads the requested processing information from the user terminal 7 and transmits it to the user terminal 7.

If the use request is not permitted in the above step 1108, this is transmitted to the user terminal 7 (or the processing of the user terminal 7 may be forcibly terminated).

In step 1111, when a request to use a single piece of processing information is received from the user terminal 7,
The read control unit 5b resets the flags of the activation information “SUB (X)” and the activation information “SUB (Y)” from “1” to “0” (step 1113), and ends the processing.

The operation process of the library management server 6 in the second embodiment is the same as that in the first embodiment, and the description is omitted. As described above, according to the second embodiment, when the library itself is commercialized, its productivity can be protected.

Further, when the user uses the library 5a in the course of executing the program, particularly when the user uses the library 5a after executing a large number of programs,
At the start of use of the library 5a, an ID check and a check of the number of available users are performed. Here, when the use request is not permitted, the user must change the contents of the program or suspend the execution. However, according to the second embodiment, a call command of the start information is created at a higher level of the user program. By doing so, it is possible to check the ID and the number of users before creating or using the program. Thereby, the burden on the user can be reduced, and the work efficiency can be improved.

In this embodiment, the ID check and the number of available users are checked by the library management server 6 which is different from the library storage server 5. Is also good.
Further, when a host computer is connected to the information processing system, the host computer may check the ID and the number of users.

[0089]

According to the present invention, a library product storing a plurality of mutually independent processing information can be protected without imposing a burden on the user.
