JP4911067B2 - License management system, terminal device, license management method, program, and recording medium - Google Patents

Description

  The present invention relates to a license management system, a terminal device, a server device, a license management method, a program, and a recording medium, and more particularly to a technique that is preferably applied to a system that checks whether software is properly acquired when an application is activated. It is.

  Conventionally, in order to prevent unauthorized copying or unauthorized use of an application, there have been various methods for checking a license when the application is started. These include a method using the MAC address of the network interface card, a method using a special license device that connects to GP-IB and generates a machine-specific license identification number, and accesses the license server every time the application is started from the client that installed the application. And a method for obtaining authentication.

  In the system using the MAC address, the license cannot be inspected when the interface card is replaced. In addition, the method using a special license device has a problem and cost of continuous support of a hardware failure and its special equipment interface, and has a problem in widespread use. In addition, the license server authentication method cannot verify the license when a network failure occurs. The above three methods are troublesome in associating a license with an inquiry when making a manufacturer support inquiry about an application usage method. In addition, there has been a software license that can be used anywhere for a limited time called a trial license. However, to change the IP address, you must replace the regular license with the trial license for a machine that is actually in operation. Was rejected by so many administrators.

  On the other hand, if you issue a license based on the machine's IP address to prevent unauthorized copying or unauthorized use of the software, you can easily verify that the machine address matches the license address when the application starts. It is. Further, since the same IP address cannot be used in the vicinity of the machine, the application by unauthorized copying becomes unusable and is a simple and good method. In recent years, many such license management methods have been seen.

  However, once the license is received, the IP address of the machine cannot be changed, which is a problem in flexible arrangement and operation management of machines and applications. In addition, when it is unavoidable to change the IP address for the convenience of the user, there is a problem that it is impossible to change the address while waiting for the arrival of a new license by performing the troublesome work of declaring the IP address to be acquired in advance to the manufacturer. there were. In this method, licenses can be issued and managed for each machine, but it is necessary to collaborate on business management between user licenses and manufacturer support to determine whether or not it is possible to respond to inquiries from users. The manufacturer only needs to issue a license based on the IP address, but for the convenience of checking the linkage with the database managed by the manufacturer support, a quick issuance on the spot is generally not expected. In any case, it took some time to reissue the license, and during that time the user could not change the machine's address. Further, when a general e-mail is used when notifying the manufacturer of the IP address to be changed, there is a risk of information leakage and the like, which causes a problem in terms of safety.

By the way, in Patent Document 1, it is possible to automate the update of the license management information at the time of device replacement of the management target device, and to reduce the man-hour for software license management and the time for license management when the management target device fails. A software license management method that can reduce system downtime is disclosed. In the software license management method, a hash value returned from the local license management server is created by the management target device creating a hash value for the combination data of the user name, software management serial number, and device specific information of the management target device. Only when the values match, the software continues to operate as if the license was continued. If the device to be managed needs to be replaced due to a failure, the local license management server hashes the new device after the replacement based on the relationship between the device specific information before the device failure and the operating environment information. The value is sent back as software license confirmation information.
JP 2006-113806 A

  The software license management method disclosed in Patent Document 1 is intended for license management in the event of a device failure, and assumes that the IP addresses before and after the device replacement are the same, and the change of the IP address is assumed. Not done. For license management in the event of a device failure, the IP address license method is used at the time of device replacement to match the licenses with the IP addresses before and after device replacement, and thereafter the MAC address method is used. For this reason, when the IP address is also changed, matching cannot be obtained, and conversion to the MAC address becomes impossible. Moreover, it cannot respond to the replacement of both the MAC address and the IP address.

  Therefore, in view of the above-described circumstances, the present invention can flexibly cope with the change of the IP address by the user when managing the software license based on the IP address, improves the usability on the user side, and efficiently on the manufacturer side. The purpose is to provide a license management system and the like that can realize efficient operation management and reduction of information leakage risk.

  In order to achieve such an object, the license management system of the present invention employs a method of issuing and managing software licenses based on the IP address of the terminal, and the user terminal and the manufacturer server are connected to the network. A license checking system for determining whether the user terminal is authorized license software using the license data including the IP address of the terminal as a license issued by a maker when the application is started; A license management means for performing a new license issuance application and a temporary license issuance application to the maker server by changing the IP address of the own terminal by transmitting and receiving an encrypted message. New license issuance application and temporary license In response to issue application, the issuance of a new license and the temporary license to the user terminal, has a license issuing unit which performs the message transceiver encrypted.

  The terminal device of the present invention is a terminal device configured by connecting to a network together with a manufacturer server a license management system that employs a method of issuing and managing software licenses based on the IP address of the terminal, When starting up the application, the license data including the IP address of the terminal itself is used as a license issued by the manufacturer to determine whether it is legitimate license software, and the IP address of the terminal is changed with respect to the manufacturer server. And a license management means for performing a new license issuance application and a temporary license issuance application by transmitting and receiving encrypted messages.

  The server device of the present invention is a server device configured by connecting to a network together with a user terminal a license management system that employs a method of issuing and managing software licenses based on the IP address of the terminal. When the application is started, the license data including the IP address of its own terminal is used as a license issued by the manufacturer to determine whether it is legitimate license software. Issuance of new licenses and temporary licenses from user terminals by sending and receiving encrypted messages and receiving new licenses and temporary licenses by issuing encrypted licenses. Means To.

  The license management method of the present invention employs a method of issuing and managing software licenses based on the IP address of the terminal, and is a license management system in which a user terminal and a manufacturer server are connected to a network. A license checking step for determining whether the license data including the IP address of the own terminal is used as a license issued by the manufacturer at the time of starting the application in the user terminal; And a license management step for sending a new license issue application and a temporary license issue application to the server by changing the IP address of the own terminal by transmitting and receiving encrypted messages. New license issuance request And receiving the temporary license issue application, the issuance of a new license and the temporary license to the user terminal, has a license issuing step of performing the message transmission and reception encrypted.

  The program of the present invention employs a method of issuing and managing software licenses based on the IP address of the terminal, and is used in a license management system in which a user terminal and a manufacturer server are connected to a network. A license check function for determining whether the license data including the IP address of the local terminal is used as a license issued by the maker at the time of application activation on the user terminal, and a maker server The computer implements a license management function for performing new license issuance application and temporary license issuance application by changing the IP address of its own terminal by sending and receiving encrypted messages. Issue license Receiving 請 and temporary license issue application, the issuance of a new license and the temporary license to the user terminal, thereby realizing a license issuing function performed by the message transmitting and receiving encrypted on a computer.

  The recording medium of the present invention is a recording medium characterized by recording the above program and being readable by a computer.

  According to the present invention, when managing a software license based on an IP address, it is possible to flexibly cope with a change of the IP address by the user, improve the usability on the user side, efficient operation management on the manufacturer side, risk of information leakage Can be reduced.

  In the license management system to which the present invention is applied, when checking whether or not the license software is genuine when the application is started, the license file calculated from the unique IP address of the machine and individually encrypted for safety is issued. When the IP address of the machine is changed, a license change application with the manufacturer and license distribution are performed by sending and receiving encrypted messages.

  In other words, in the present invention, an IP address-based license scheme is used, and in order to deal with the above-described problems, the user side determines whether the license is a license that has been issued from the manufacturer as before. There is provided a license management means for performing an inspection means, a process for creating and sending an IP address change application message, a provisional license and a regular license from a manufacturer, and the like. In addition, when the manufacturer receives an IP address change application, the manufacturer has a license issuing means for issuing a temporary license with a predetermined time limit and reissuing a regular license whose IP address has been changed later. Therefore, the user can change the machine IP address immediately without waiting for reissuance of the license whose IP address has been changed by using the temporary license during this period. In addition, the message between the license main body and the user and the manufacturer is encrypted to solve the problem of user information leakage such as license falsification and IP address.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing the configuration of the license management system of this embodiment. The license management system according to the present embodiment includes a target machine 110 of a user 100, a target application 120 used by the user on the machine, a license management unit 130 that is executed when the application is activated in the application, and a license management unit. A message transmission / reception means 140 for sending the created IP address change application message, a network 105 connecting the user target machine 110 and the message transmission / reception means 140, and a message transmission / reception means 160 of the manufacturer 150 for sending / receiving messages from the user Inquiry management means 180 for managing questions relating to applications licensed by the manufacturer, and an IP address change application or temporary label from the user in synchronization with the inquiry management means. A license management issuing means 170 that performs sensing of issue management, and network 155 of the manufacturer, and a Internet 190 that connects the user network and the manufacturer network.

  In FIG. 1, a license management issuance means 170 is connected to an intranet 155, and an encrypted issuance message transmission of a user distribution software license and a license from a user via a message transmission / reception means 160 similarly connected. The encrypted application message regarding the content change is received, and the processed result is shared with the inquiry management unit 180. In the software license for user distribution, the IP address of the target machine 110 on the user 100 is encrypted and stored. Then, when the target application 120 on the target machine 110 is activated, whether or not the license is properly issued, first, the license management unit 130 reads the license file using the manufacturer encryption key stored in the application, and decrypts the license file. It is checked whether or not the IP address stored in the license matches the IP address stored in the license. If they match, the application is started. When a user uses the application and receives support for questions from the manufacturer, the manufacturer can manage the association between the license and the user simply by checking the IP address of the machine on which the application operates and writing it in the inquiry mail. Become.

  If it is desired to change the machine IP address for the convenience of the user, the message transmission / reception means 140 is created after the application form with the change destination IP address is created and encrypted using the IP address change application menu in the license management means 130. To the manufacturer via The manufacturer receives the message by the message transmitting / receiving means 160 and sends it to the license management issuing means 170. The license management issuing means decrypts the message, analyzes the contents of the user application, creates and encrypts a reissued license with contents corresponding to the change destination IP address, and similarly distributes the license by sending a message to the user. Reissuing a regular license requires manual approval, and it often takes some time because the user DB needs to be updated in cooperation with inquiry support.

  Since the user cannot change the machine IP address while waiting for the regular license to be issued, the user makes a provisional license application of the license management means 130. The temporary license application is also sent to the manufacturer as a message in the same manner as the IP address change application. The temporary license is a limited license with a time limit until the regular license issuance, and is normally issued quickly without approval through manual operation, so that the waiting time for changing the IP address is greatly reduced.

  Next, the operation in the license management system of this embodiment will be described in detail. FIG. 2 is a flowchart showing the flow of application license inspection processing in the present embodiment. When the user starts the application, the license is read from the license information in the form of a file or the like in the execution license check (step S200) (step S202). Next, it is determined whether the license is normal or not (step S203 / NO), and the process proceeds to a user license management flow (license reissue) in FIG. 3 described later (step S204). If the license is normal (step S203 / YES), whether the license is normally issued by the manufacturer or the temporary license temporarily issued by the manufacturer by changing the IP address or the like is checked for the regular license (step S205). Or a temporary license check (step S250).

  FIG. 5 shows an example of this license file. The license file example 500 has a license file readable ASCII description part example 510 at the head thereof, followed by a license body encryption part example 520 and a license file signature example (including a license file digest and a maker encryption key) 530. ing.

  Returning to the flow of FIG. 2, both the regular license and temporary license inspection steps are performed using the manufacturer encryption key (steps S212 and S257), and the license files are decrypted by the license decryption (steps S210 and S257). Step S255). Then, the digest is actually calculated from the license file by the license digest calculation (steps S215 and S260). In determining whether the digests match, a comparison is made with a digest embedded in the license file in advance for tampering check (steps S220 and S265). If they match, it indicates that the license was successfully decrypted without falsification.

  Next, the IP address of the machine on which the application runs and the machine IP address of the license described in the license are acquired (step S225). Subsequently, it is determined whether or not the two acquired addresses match (step S230), and if they match, the application is normally started (step S230 / YES, step S235). If the addresses do not match (step S230 / NO), the user has already changed the machine IP address without going through a normal procedure, so it is considered that an IP address change application and a license reissue are necessary, and will be described later with reference to FIG. The process proceeds to the user license management flow (IP address change) (step S232).

  On the other hand, in the case of a temporary license, if the match of the digest of the temporary license matches (step S265 / YES), it is assumed that the temporary license has not been tampered with or illegally used, and the process proceeds to a temporary license content inspection process. In addition, the temporary license may be a license that limits a valid machine address or a license that has only an expiration date without address restriction. If the address is restricted, a license address that can operate anywhere within the 192.215.136 network, such as 192.215.136.255, is possible. As the temporary license content inspection, first, a process of reading an address described in such a temporary license is performed (step S270). Then, a machine address is acquired (step S275).

  Next, the acquired addresses are matched to determine whether the IP address in the temporary license is valid (step S280). Subsequently, the expiration date of the temporary license described in the temporary license file and the set date and time of the machine are read, and it is determined whether the temporary license in the machine is within the expiration date (step S285). If it is within the time limit (step S290 / YES), the application is executed normally as in the case of the regular license (step S235). If the license has expired (step S290 / NO), the temporary license needs to be reacquired, and the process moves to the user license management flow (provisional license issuance) of FIG. 3 described later (step S292).

  FIG. 3 is a flowchart showing a flow of license management processing on the user side in the present embodiment. In this flow, the user side performs any of registration processing accompanying license update, change application for IP address change, provisional license issuance application, and license reissue application. For these processes, the license management means 300 is activated by the user via an application or alone. When activated, any of the license update (step S302), IP address change (step S330), provisional license application (step S340), and license reissue (step S350) for registration of a regular or temporary license is selected by the user menu selection. Is determined.

  In the case of license update (step S302 / YES), message reception processing is performed (step S304). Here, for example, it is only necessary to access a pre-registered user's sendmail or a machine on which a pop server or the like operates, and obtain a message related to the application license based on the subject of the message. An example of this message is shown in FIG. The message example 600 includes only a message header example 610 including To, From, Subject, and the like, and a message body encryption unit example 620, and the contents cannot be read even if an information leakage accident occurs. Here, an example of an S / MIME message is shown.

  Returning to the flow of FIG. 3, after the message is received, the message is decrypted using the manufacturer encryption key (steps S312 and S306). Subsequently, in order to determine whether or not the message itself has been tampered with, the digest of the message itself is calculated to extract the digest embedded in the message (step S308). Further, the license is extracted from the decrypted message (step S310), and the license is decrypted using the manufacturer encryption key (step S313, step S314). Then, the digest of the decrypted license file is calculated (step S316).

  The calculated digest is compared with the digest value in the license file, and if they match, it indicates that the falsification has not been made (step S318). If it has not been tampered with (step S318 / YES), the IP address of the machine is acquired, the machine address written in the license is compared with the actual machine address, and it is determined whether or not the license has been properly licensed (step S318 / YES). Step S322). If it is determined that the license is properly licensed (step S322 / YES), the license information is stored in the license information storage directory predetermined by the application, and the license update process is performed (steps S324 and S326).

  When the IP address is changed (step S330 / YES), a new IP address (transfer destination IP address) is input (step S346), and an IP address application message creation process addressed to the manufacturer is performed (step S342). Also, the existing license information is read from the license information storage directory (step S338), attached to the created IP address application message (step S336), and an IP address change application message is created (step S360). Thereafter, in order to prevent message tampering, a digest of the message is calculated (step S362), and message encryption is performed using the manufacturer encryption key (step S364, step S366). Then, the encrypted message is transmitted as an application message addressed to the manufacturer (step S368).

  In the case of a temporary license application (step S340 / YES), the existing license information is read from the license information storage directory (step S346), and a temporary license application message creation process addressed to the manufacturer is performed (step S342). Then, the old license information read is attached to the created temporary license application message (step S344), and a temporary license issuance application message is created (step S360). After that, as in the case of license update, message digest calculation (step S362), message encryption (step S364, step S366), and application message are transmitted (step S368).

  In the case of license reissue (step S350 / YES), existing license information is read from the license information storage directory (step S356), and a process for creating a license reissue message addressed to the manufacturer is performed (step S352). Then, the old license information read is attached to the created license reissue message (step S354), and a license reissue application message is created (step S360). Thereafter, as in the case of license update or provisional license application, message digest calculation (step S362), message encryption (step S364, step S366), and application message transmission are performed (step S368).

  FIG. 4 is a flowchart showing the flow of processing for license management and license issuance on the maker side in the present embodiment. The message from the user arrives at the message transmission / reception means 160 in FIG. 1. First, the license management issuing means 170 makes an appropriate decision from the message Subject and receives only the message related to the license (step S400). Since all the messages related to the received license are encrypted, the message decryption process is performed using the manufacturer encryption key (steps S402 and S403). Subsequently, the inside of the decrypted message is analyzed (step S404), and an application for changing the IP address (step S406), an application for issuing a temporary license (step S420), or a license for some reason such as an accident or license damage It is determined whether the application is related to reissuance (step S440). This can be easily determined by inserting, for example, a character string for determining change, temporary license, or reissue at the beginning of the message.

  In the case of an application relating to the IP address change (step S406 / YES), first, the user migration destination machine IP address and the old machine IP address described in the message are read to obtain the IP address (step S408). Subsequently, the IP address on the user's old license is obtained from the user DB, and the user information is verified by comparing with the read old machine IP address, and the user customer number, product serial number, etc. are obtained (step S410, Step S411). Then, the product serial number is obtained from the product DB, matched with the previous user-used application product serial number, and product information is verified (steps S412 and S413). Then, a new license corresponding to the new IP address after the change (user migration destination machine IP address) is created, and the user DB is updated (steps S414 and S415).

  The subsequent processing is as follows, similar to the temporary license issuance (step S420) and the license reissue (step S440). In order to prevent falsification, the digest value of the license file description content is calculated to create a license digest (step S460). Next, a license encryption process is performed using the manufacturer encryption key (steps S462 and S463). Subsequently, a message body and a message header are created in the previous license (step S464), and a message digest is created by calculating the digest value of the message body (step S466). Then, after being attached to the rear part of the message, the message is encrypted using the manufacturer encryption key (step S468, step S469), and the message is transmitted to the user (step S470).

  In the case of an application related to provisional license issuance (step S420 / YES), as in the case of IP address change (step S406), user information verification using a user DB and product information acquisition using a product DB are performed (step S406). S422 to step S425).

  In the provisional license issuance, a license is issued so that any machine can be operated within the time limit or an address can be freely set within a certain network. For example, the IP address of the license is set to 255.255.255.255 and ANDed with the real IP address of the user, and each dot notation digit is valid if it is not zero. That is, in this case, any IP address is a valid address. Alternatively, as shown in FIG. 6, the network part of the user's IP address such as 0.0.0.255 is designated as the class C address, and only the host address part is designated as 255. The digit of 0 is ignored, and the AND operation is performed for only the digit of 255, and if it is not 0, it may be determined that the address is valid for the license.

  In such cases, it is effective to describe the date and time to be expired in the license file in order to prevent unauthorized use of the temporary license. The temporary license issuance process is the same as the regular license issuance. However, in the present embodiment, it is assumed that the temporary license is issued quickly. Therefore, the temporary license issuance count is limited for each user and the issuance count is limited. The normal number of times may be determined (steps S426 and S428), and an alert may be sent to the person in charge when a predetermined number of times is exceeded, and the subsequent processing may be performed manually.

  If there is no problem with the number of issues (step S428 / YES), a temporary license is created and the user DB is updated (steps S430 and S431). The subsequent processing is the same as the IP address change (step S406) and license reissue (step S440), and the license digest creation, license encryption using the maker encryption key, message creation, message digest creation, maker encryption Message encryption using the key and message transmission are performed (steps S460 to S470).

  In the case of an application related to license reissue (step S440 / YES), as in the case of temporary license issuance (step S420), user information verification using the user DB, acquisition of product information using the product DB, issuance count The number of times is determined (steps S442 to S448). If there is no problem with the number of issues (step S448 / YES), a license is created and the user DB is updated (steps S450 and S451). The subsequent processing is the same as IP address change (step S406) and provisional license issuance (step S420). License digest creation, license encryption using a maker encryption key, message creation, message digest creation, maker encryption Message encryption using the key and message transmission are performed (steps S460 to S470).

  In the above-described embodiment, a license is issued and managed based on a machine IP address without using a special license device. For this reason, unauthorized use such as simultaneous activation on a plurality of machines is difficult. In addition, when inquiring to the manufacturer support for questions regarding the use of the application, it is only necessary to report the IP address of the machine, and the manufacturer issues a license such as associating whether the application is a legally licensed application. Management becomes easy.

  Further, according to the above-described embodiment, when changing the machine IP address, the user does not wait for the arrival of the regular license by the IP address change application message and the application message for acquiring the temporary license that can be quickly distributed. The machine IP address can be changed, and flexible arrangement and operation management of machines and applications are possible.

  Further, according to the above-described embodiment, the license content change application message with the manufacturer is subjected to two-way encryption and falsification prevention inspection, and the risk of information leakage such as the license content and IP address, and the machine It is safer in terms of attack risk.

  In the present invention, the following modifications are possible in addition to the above-described embodiments. In the above embodiment, the temporary license address specification is described in which the network part of the user machine IP address is set to 0.0. 0 and the host part is set to 255 as the temporary license. As a first modification, a network such as 0.0.0.80 that can freely change the host partial address from 1 to 128 so as to prevent license abuse and to set an IP address within a certain range. A temporary license addressing method using a mask can also be easily implemented.

  In the temporary license in the above embodiment, the host part of the user machine IP address is set to 255 and a temporary license that can freely change the address of the host part can be issued, but there is a problem that the address of the network part cannot be changed. Therefore, as a second modification, it is possible to easily implement a method in which a user designates an IP address to be transferred at the time of application for a temporary license at the time of application, and a temporary license is issued temporarily with the IP address at the time of application instead of a mask address. is there.

  In the above embodiment, both the regular license and the temporary license are issued for each machine, and each license file is a unique license file. As a third modification, multiple IP addresses for licenses on the license file are arranged at a time, and the license file is copied and used on each machine. Operation is easy to implement.

  In the above embodiment, assuming that the user does not have a public key and can not send / receive the mail of the public key encryption method, the message is directly read in the application, the message by encryption, decryption, digest operation, We are conducting license tampering inspection. As a fourth modification, if the user has a public key, secret key, encryption and signed mail transmission / reception environment issued by a third party, a message transmission / reception and license distribution method by S / MIME is possible. is there. In this case, the safety of information is further improved.

  The above-described embodiment is a preferred embodiment of the present invention, and the scope of the present invention is not limited to the above-described embodiment alone, and various modifications are made without departing from the gist of the present invention. Implementation is possible.

  That is, the user terminal and the maker server in the above-described embodiment operate by processing, means, and functions executed by a computer according to program instructions. The program sends a command to each component of the computer, checks the license by the predetermined processing and function as described above, for example, the license management unit 130, and according to the type of license and the acquired information, For each necessary process (IP address change, provisional license application, license reissue, etc.), a process of applying to the manufacturer server by sending and receiving an encrypted message is performed. In addition, the license management issuing unit 170 receives an application message from the user side (license management unit 130), and performs various processes (IP address change, provisional license application, license reissue, etc.) to update the user DB. Then, a process of issuing a license (new license, temporary license, reissue license) to the user terminal by transmitting / receiving an encrypted message is performed. As described above, the processes and means in the above-described embodiment are realized by specific means in which the program and the computer cooperate.

  Then, for example, a computer (CPU) of a user terminal or a manufacturer server is stored in the storage medium via a computer-readable recording medium that records the program code of the software that realizes the functions of the above-described embodiment, that is, the storage medium. The object of the present invention can also be achieved by reading and executing the program code. Further, the program can be loaded and executed directly on a computer through a communication line without going through a recording medium, and the object of the present invention can be achieved similarly.

  In this case, the program code itself read from the storage medium or loaded and executed through the communication line realizes the functions of the above-described embodiment. And the storage medium which memorize | stored the program code comprises this invention.

  Examples of the storage medium for supplying the program code include a floppy (registered trademark) disk, a hard disk, an optical disk, a magneto-optical disk, a CD-ROM, a CD-R, a nonvolatile memory card, a ROM, and a magnetic tape. Can be used.
