Description

  The present invention relates to a storage medium, a software management system, and an installation program.

  Generally, software is stored in a read-only storage medium such as a CD-ROM or a write-once storage medium such as a CD-R that can be written only once, and is provided to a user. In recent years, software provided to users has taken measures to prevent unauthorized copying and unauthorized use. For example, in order to prevent unauthorized copying of software, a technique for providing software using a dedicated CD and a dedicated program with a security function added to a CD-R has been proposed.

  Alternatively, a software management system that manages software using a management server connected via a network to a computer on which the software is executed has been proposed in order to prevent unauthorized use of the software (for example, Patent Documents). 1). In this case, the software management system operates with the resident software on the management server and the resident software on the computer.

JP 2004-62561 A

  In the software management system of Patent Document 1, it is necessary to operate management resident software or the like on the server 30 for managing permission or the like for starting up the software. Therefore, there is a cost for preventing unauthorized use of the software. May increase. In addition, in the method using a dedicated CD, an inexpensive commercially available CD-R cannot be used as it is, so that the cost for preventing unauthorized copying of software increases.

  An object of the present invention is to prevent unauthorized use of software stored in a write-once storage medium at a low cost.

  The write-once storage medium stores a data file to be installed, an installation program for installing the data file in the computer, and an identification file for individually identifying the storage medium. For example, when a data file is newly installed in a computer, the installation program causes the computer to execute a first determination process, a second determination process, and a new installation process.

  The first determination process is executed before installing the data file on the installation target computer, and determines whether the identification file exists on the installation target computer. The second determination process is executed when the result of the first determination process indicates that the identification file does not exist, whether or not the predetermined server is accessed via the network and the identification file is registered in the predetermined server. Determine whether. The new installation process is executed when the result of the second determination process indicates that the identification file has not been registered, and the data file is installed on the computer to be installed and the identification file is registered on a predetermined server.

  According to the present invention, unauthorized use of software stored in a write-once storage medium can be prevented at low cost.

It is a figure which shows an example of CD-R, a computer, and a server in case the new installation process shown in FIG. 2 is implemented. It is a figure which shows an example of CD-R, a computer, and a server in case the reinstallation process shown in FIG. 2 is implemented. It is a figure which shows an example of CD-R, a computer, and a server in case the installation cancellation process shown in FIG. 2 is implemented. It is a figure which shows the modification of the process shown in FIG.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 shows an embodiment of the present invention. The software management system of this embodiment includes a CD-R 10 that is a storage medium readable by the computer 20 and a server 30 connected to the network NET.

  The CD-R 10 is a write-once storage medium that can be written only once. For example, the software provider writes the data file 12, the installation program 14, and the identification file 16 on the CD-R 10. That is, the CD-R 10 stores a data file 12 to be installed, an installation program 14, and an identification file 16.

  The data file 12 is, for example, encrypted data, and is software provided to the user via the CD-R 10. The installation program 14 is, for example, a program that causes the computer 20 to execute processing for installing the data file 12 on the computer 20. Details of the processing of the installation program 14 will be described later with reference to FIG.

  The identification file 16 is an identification file for individually identifying the CD-R 10 in which the data file 12 is stored. For example, the file name of the identification file 16 is different for each CD-R 10 in which the data file 12 is stored. In this case, since the CD-R 10 is identified by the file name of the identification file 16, the contents of the identification file 16 may be empty. The identification file 16 is confused with, for example, the data file 12 and the installation program 14 in order to prevent detection by a third party other than the software provider.

  The computer 20 is a computer to be installed, for example, and has a CD drive 22 for reading data stored in the CD-R 10. The computer 20 can be connected to a network NET. The server 30 is, for example, a computer on the software provider side, and has a database 32 in which the identification file 16 is registered. For example, the database 32 is accessed via the network NET to the computer 20 on which the installation program 14 is executed.

  FIG. 2 shows an example of processing of the installation program 14 shown in FIG. Processing S100-S160 is implemented by computer 20 shown in Drawing 1 mentioned above, for example. For example, when the CD-R 10 is inserted into the CD drive 22 of the computer 20, the installation program 14 stored in the CD-R 10 is activated, and the process S100 is performed. That is, the installation program 14 causes the computer 20 to execute processes S100 to S160.

  In the process S100, the computer 20 determines whether or not the installation target computer 20 has the identification file 16 having the same file name as the identification file 16 of the CD-R 10 inserted into the CD drive 22. When the identification file 16 having the same file name as the identification file 16 of the CD-R 10 does not exist in the computer 20 (No in step S100), the operation of the computer 20 proceeds to step S110.

  On the other hand, when the identification file 16 having the same file name as the identification file 16 of the CD-R 10 exists in the computer 20 (Yes in the process S100), the computer 20 performs a reinstallation process in the process S140. That is, the process S100 is a process that is executed before the data file 12 is installed in the computer 20 to be installed, and determines whether or not the installation of the data file 12 is a reinstallation.

  In process S <b> 110, the computer 20 accesses the database 32 of the server 30. For example, an access destination URL (Uniform Resource Locator) is specified by the installation program 14. In addition, when the access to the database 32 of the server 30 fails in the process S110, the computer 20 displays, for example, on the display (not shown) of the computer 20 that the connection to the server 30 has failed, and the installation program The process 14 is finished.

  In process S <b> 120, the computer 20 determines whether or not the identification file 16 of the CD-R 10 inserted into the CD drive 22 is registered in the database 32 of the server 30. When the identification file 16 of the CD-R 10 is not registered in the database 32 (No in step S120), the computer 20 performs a new installation process in step S130. On the other hand, when the identification file 16 of the CD-R 10 is already registered in the database 32 (Yes in process S120), the computer 20 performs an installation stop process in process S150. That is, the process S120 is a process that is executed when the determination result of the process S100 indicates that the identification file 16 does not exist, and determines the unauthorized use of the data file 12 stored in the CD-R 10.

  In the new installation process of process S130, the computer 20 copies the data file 12 and the identification file 16 stored in the CD-R 10 to the computer 20. For example, the data file 12 is copied to a designated folder designated by the installation program 14. Note that the designated folder may be designated by the user via the installation program 14. For example, the identification file 16 is copied to a location different from the designated folder in order to prevent detection by a third party other than the software provider.

  Then, the computer 20 decrypts the data file 12 and newly installs the data file 12 in the computer 20. Further, in the new installation process, the computer 20 registers the identification file 16 stored in the CD-R 10 in the database 32 of the server 30. As a result, the identification file 16 of the CD-R 10 storing the data file 12 on which the installation process has been performed is registered in the database 32 of the server 30.

  That is, the process S130 is executed when the determination result of the process S120 indicates that the identification file 16 is not registered, and the data file 12 is installed in the installation target computer 20 and the identification file 16 is registered in the database 32 of the server 30. It is processing to do. After the identification file 16 is registered in the database 32 of the server 30, the operation of the computer 20 proceeds to processing S160.

  In process S160, the computer 20 deletes unnecessary files in the designated folder. The unnecessary file is, for example, a file temporarily generated by the installation process, and is a file that is not necessary for the operation of the software set to be usable by the installation of the data file 12. Note that the identification file 16 copied to the computer 20 is a file necessary for re-installation (a file searched in the process S100) and is not deleted.

  In the re-installation process of process S140, since the identification file 16 to be registered is already registered in the database 32 of the server 30, the process of registering the identification file 16 stored in the CD-R 10 in the database 32 is not performed. . Other processes of the reinstallation process are almost the same as the new installation process of process S130. That is, the process S140 is a process that is executed when the determination result of the process S100 indicates the presence of the identification file 16 and reinstalls the data file 12 in the computer 20 to be installed. In the reinstallation process, since the identification file 16 has already been copied to the computer 20, the process of copying the identification file 16 stored in the CD-R 10 to the computer 20 may be omitted. After the re-installation process ends, the operation of the computer 20 proceeds to process S160.

  In the installation cancellation process of process S150, the computer 20 ends the process of the installation program 14 without installing the data file 12 in the computer 20. For example, the computer 20 displays on the display (not shown) that the installation process is to be stopped, and ends the process of the installation program 14. As described above, in this embodiment, since the installation cancellation process is executed when the determination result of the process S120 indicates that the identification file 16 has been registered, unauthorized installation of the data file 12 stored in the CD-R 10 is prevented. it can. As a result, in this embodiment, unauthorized use of software can be prevented.

  Further, in this embodiment, since it is not necessary to operate management resident software or the like on the server 30, it is possible to suppress an increase in cost for preventing unauthorized use of software. Furthermore, in this embodiment, the data file 12, the installation program 14, and the identification file 16 need only be stored in the CD-R 10, and an inexpensive commercially available CD-R 10 can be used as it is. Therefore, in this embodiment, unauthorized use of software can be prevented at low cost.

  FIG. 3 shows an example of the CD-R 10, the computer 20, and the server 30 when the new installation process shown in FIG. The file name FILE1 indicates the file name of the identification file 16A of the CD-R 10A. File names FILE2 and FILE3 indicate file names of the identification file 16 in the CD-R 10 different from the CD-R 10A. For example, the file name FILE2 indicates the file name of the identification file 16B of the CD-R 10B shown in FIG.

  The CD-R 10A stores an identification file 16A with a file name FILE1. Further, the computer 20 does not have the identification file 16A having the file name FILE1. In the database 32 of the server 30, the identification file 16 with the file name FILE2 and the identification file 16 with the file name FILE3 are already registered. That is, the identification file 16A with the file name FILE1 is not registered in the database 32. In this case, for example, when the CD-R 10A is inserted into the CD drive 22 of the computer 20, the above-described new installation process shown in FIG. 2 is performed, and the data file 12 stored in the CD-R 10A is stored in the computer 20 Newly installed.

  FIG. 4 shows an example of the CD-R 10, the computer 20, and the server 30 when the reinstallation process shown in FIG. The meanings of the file names FILE1, FILE2, and FILE3 are the same as those in FIG. FIG. 4 corresponds to the state after the new installation process is performed in FIG. 3 described above.

  For example, the computer 20 already has an identification file 16A with the file name FILE1. In the database 32 of the server 30, the identification file 16A with the file name FILE1, the identification file 16 with the file name FILE2, and the identification file 16 with the file name FILE3 are already registered.

  Therefore, for example, when the CD-R 10A is inserted into the CD drive 22 of the computer 20, since the identification file 16A of the CD-R 10A already exists in the computer 20, the reinstallation process shown in FIG. 2 described above is performed. . Note that the computer 20 on which the reinstallation process is performed does not need to access the database 32 of the server 30, and therefore may not be connected to the network NET.

  FIG. 5 shows an example of the CD-R 10, the computer 20, and the server 30 when the installation cancellation process shown in FIG. The meanings of the file names FILE1, FILE2, and FILE3 are the same as those in FIG. For example, the file name FILE2 indicates the file name of the identification file 16B of the CD-R 10B.

  The CD-R 10B stores an identification file 16B having a file name FILE2. Further, the computer 20 does not have the identification file 16B having the file name FILE2. In the database 32 of the server 30, the identification file 16 with the file name FILE2 and the identification file 16 with the file name FILE3 are already registered. Therefore, for example, when the CD-R 10B is inserted into the CD drive 22 of the computer 20, since the identification file 16B that does not exist in the computer 20 is already registered in the database 32, the above-described installation cancellation process shown in FIG. To be implemented.

  That is, the computer 20 on which the installation program 14 is operating determines that the CD-R 10B is an unauthorized CD-R, and the installation program 14 does not install the data file 12 stored in the CD-R 10B on the computer 20. Terminate the process. Here, for example, when the data file 12 stored in the CD-R 10B is an illegally copied data file 12, the CD-R 10B is an unauthorized CD-R. Alternatively, for example, when one CD-R 10B is used for a plurality of computers 20 in order to install the data file 12 on a plurality of computers 20, the CD-R 10B used for the second and subsequent computers is illegal. CD-R.

  As described above, in this embodiment, the CD-R 10 includes the data file 12 to be installed, the installation program 14 for installing the data file 12 in the computer 20, and the identification file 16 for individually identifying the CD-R 10. Is memorized. If the identification file 16 that does not exist in the computer 20 is already registered in the server 30, the computer 20 that operates based on the installation program 14 does not install the data file 12 in the computer 20. Therefore, in this embodiment, unauthorized use of software stored in a write-once storage medium can be prevented at a low cost.

  In the above-described embodiment, the example in which the data file 12, the installation program 14, and the identification file 16 are stored in the CD-R 10 has been described. The present invention is not limited to such an embodiment. For example, the data file 12, the installation program 14, and the identification file 16 may be stored on a DVD-R. Alternatively, the data file 12, the installation program 14, and the identification file 16 may be stored in a write-once storage medium different from the CD-R and DVD-R. In this case, the computer 20 has a drive corresponding to each storage medium. Also in this case, the same effect as the above-described embodiment can be obtained.

  In the above-described embodiment, the example in which the encrypted data file 12 is stored in the CD-R 10 has been described. The present invention is not limited to such an embodiment. For example, the data file 12 may be stored in the CD-R 10 without being encrypted. Also in this case, the same effect as the above-described embodiment can be obtained.

  In the above-described embodiment, the example in which the server 30 includes the database 32 has been described. The present invention is not limited to such an embodiment. For example, the server 30 may have a registration folder (area) to which the identification file 16 is copied instead of the database 32. In this case, the computer 20 registers the identification file 16 in the server 30 by copying the identification file 16 of the CD-R 10 used for installation to the registration folder of the server 30. Also in this case, the same effect as the above-described embodiment can be obtained.

  In the above-described embodiment, the example in which the identification file 16 is registered in the server 30 before the unnecessary file deletion (processing S160 in FIG. 2) described in FIG. The present invention is not limited to such an embodiment. For example, the identification file 16 may be registered in the server 30 after the unnecessary file is deleted. In this case, the post-process of the process S160 shown in FIG. 2 is performed in the new installation process (process S130 in FIG. 2) and the re-install process (process S140 in FIG. 2), respectively. Also in this case, the same effect as the above-described embodiment can be obtained.

  Furthermore, as shown in FIG. 6, the identification file 16 may be registered in the server 30 before the installation process is performed. FIG. 6 shows a modification of the process shown in FIG. In the process illustrated in FIG. 6, processes S132 and S142 are performed instead of the processes S130, S140, and S160 illustrated in FIG. Other processes are the same as those in FIG.

  The process S132 is a process that is executed when the determination result of the process S120 indicates that the identification file 16 is not registered, and the identification file 16 is registered in the database 32 of the server 30. After the identification file 16 is registered in the database 32 of the server 30, the operation of the computer 20 proceeds to processing S142. The installation process of the process S142 corresponds to the process S140 and the process S160 illustrated in FIG. For example, in process S142, the data file 12 is installed in the computer 20, and unnecessary files other than the identification file 16 are deleted. Also in this case, the same effect as the above-described embodiment can be obtained.

  As mentioned above, although this invention was demonstrated in detail, said embodiment and its modification are only examples of this invention, and this invention is not limited to this. Obviously, modifications can be made without departing from the scope of the present invention.

  The present invention can be used for a storage medium, a software management system, and an installation program.
