Description

  The present invention relates to an information processing apparatus, an information processing system, an information processing method, and a program that employ a software system that operates in an object-oriented environment that can be applied to communication control processing of an electronic device such as a card reader / writer. .

An information processing system including an information processing apparatus that employs a software system that operates in an object-oriented environment includes, for example, an electronic device such as a card reader / writer and a host device such as an ATM that communicates with the card reader / writer.
IC card (contact IC card) that is used in financial institutions, etc., as a card that realizes cashless and personal authentication, etc., with an integrated circuit chip (IC chip) embedded inside a plastic substrate and an IC terminal on the surface There is also an IC card (non-contact IC card) in which an antenna coil is arranged.
Information is reproduced or recorded on the IC card by a card reader / writer as an electronic device.

The card reader / writer receives a command (command APDU: Application Protocol Data Unit) from the host device and converts the command into a format (command TPDU: Transmission Protocol Data Unit) according to the communication protocol with the IC card.
Then, after converting the voltage, communication speed, etc., the command is transmitted to the IC card. Further, after receiving the response from the IC card, reverse conversion (conversion from response TPDU to response APDU) is performed, and the response is transmitted to the host device.

Communication between the host device and the card reader / writer is generally RS232C or USB (Universal Serial Bus), and communication between the card reader / writer and the IC card is TTL level, USB, and non-contact communication. Etc. are common.
In general, the card reader / writer simply performs a process of converting into TPDU without interpreting the data content of the APDU.

In a host device such as an ATM that communicates with an electronic device such as a card reader / writer, a communication control class library (software system) that operates in an object-oriented environment in order to control communication with the electronic device. May apply.
The target communication control class library encapsulates the communication protocol with the target card reader / writer, and provides an interface for command transmission and response reception for the card reader / writer to function. And

Hereinafter, as an example, a class library developed in Java (registered trademark) which is an object-oriented programming language will be described.
Middleware developed in Java is generally provided in a form of a class library.

A class library developed in the Java language is generally provided by arranging a plurality of classes in a name space and collecting them in one file. This namespace is called a package.
The arrangement of the library in the package is realized in the form of a folder structure (hierarchical structure using folders), and is generally distributed as a compressed file in the form of jar (file format) while maintaining this folder structure. . Note that jar is a form of file compression by the zip method.
An example is shown below.

By the way, the class library is applied as a compressed file called jar. However, the method for acquiring the unique information of the file, for example, version information, is not generalized and is not specifically shown.
However, the following first to fourth methods are conceivable as methods for acquiring the version information of the file.
These methods and their problems are described below.

[First method]
The first method is a method of embedding version information in a manifest file.
In this first method, it is possible to execute a predetermined program and read information embedded in the “manifest file”.
However, this case has the following disadvantages.
Generally, an operating system (OS) searches for a file according to a predetermined search rule.
In the method of acquiring version information by executing an application program, if there are multiple jar files that store the class library for which version confirmation is to be performed, something different from the intended one is loaded, resulting in incorrect information There are concerns about the situation of acquisition.
The method of acquiring version information by executing a method from an application program is only in the category of indirect information acquisition methods, so it is necessary to set environment settings in advance, such as whether there is a jar file as in the previous example. It is necessary to be careful.
In addition, since an operation on a CUI (Character User Interface) is essential, it is easy to make a mistake when inexperienced.

Moreover, according to the first method, there are the following disadvantages.
Class library packages are usually distributed as jar files. As described above, the jar file is a form of zip that is a file compression method.
For this reason, there is a method of reading the version information by once decompressing the jar file, taking out the manifest file, and browsing with a text editor. In this case, dedicated software is required for decompression and browsing. Moreover, the trouble for that arises.

[Second method]
The second method is a method of implementing a method (procedure) for notifying the version.
However, the second method has the following disadvantages.
In the second method, since the method can be executed only through another software module, it is necessary to separately prepare an application program that is another software module.
In the second method, the version confirmation is performed when the user starts to develop the software that uses the software or upgrades the class library, such as when the user knows about the class library or the software development environment for using the class library. Most of the cases are necessary in situations where you do not have enough.
The creation of an application program under such circumstances is a burden on the user and causes time for confirmation.

The second method has the same disadvantage as the first method described above.
Generally, the OS searches for a file according to a predetermined search rule.
In the method of acquiring version information by executing an application program, if there are multiple jar files that store the class library for which version confirmation is to be performed, something different from the intended one is loaded, resulting in incorrect information There are concerns about the situation of acquisition.
The method of acquiring version information by executing a method from an application program is only in the category of indirect information acquisition methods, so it is necessary to set environment settings in advance, such as whether there is a jar file as in the previous example. It is necessary to be careful.

[Third method]
The third method is a method of embedding version information in a binary image.
However, the third method has the following disadvantages.
In software development using the Java language, there is no method for designating an output position in a binary image. Therefore, in the third method, it is necessary to be able to search by providing a keyword or the like.
In the third method, a binary editor is required for browsing.
Also, the jar file is a compressed file, and the original binary image does not remain the original. Therefore, it is meaningless to browse the jar file directly. For this reason, in the third method, a file in which version information is written is browsed once. However, since the file is usually composed of a plurality of original files, which of the files has a version written in it. It is necessary to clarify whether there is another rule.
In the third method, when obfuscation processing is performed, there are cases where readability cannot be ensured.

[Fourth method]
The fourth method is a method of reflecting version information in the file name.
However, according to the fourth method, the renaming of the file is easy without any restrictions on the user and is easy to be confused.

  An object of the present invention is to provide an information processing apparatus, an information processing system, an information processing method, and a program capable of directly and easily acquiring unique information such as file version information.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
In the following embodiments, a card reader / writer will be described as an example of an electronic apparatus device.

  FIG. 1 is a block diagram showing an overview of an information processing system according to an embodiment of the present invention.

  The information processing system 10 includes a host device (host device) 20 as an information processing device, a card reader / writer (electronic device device) 30, and an IC card 40.

In this embodiment, the host device 20 such as an ATM that communicates with an electronic device such as a card reader / writer is used for communication control that operates in an object-oriented environment in order to control communication with the electronic device. A class library (software system) is applied.
The host device 20 stores an application program AP to be provided. The application program AP is a program described in Java (registered trademark), which is one of object-oriented computer languages, and is configured by Java bytecode that can be executed in the Java execution environment.
In the present embodiment, a Java (registered trademark) application execution device that executes a Java (registered trademark) application program described in the Java (registered trademark) language as an example of the program execution device according to the present invention is illustrated in the drawings. Will be described with reference to FIG.

[Configuration and function of host device]
The host device 20 performs communication control with the card reader / writer 30, exchanges various information such as receiving a response corresponding to the transmission of the command, and acquires information from the card reader / writer 30.

FIG. 2 is a diagram conceptually illustrating a configuration example of the host device according to the present embodiment.
2 basically includes a CPU 21, a ROM 22, a RAM 23, a storage unit 24, a display device 25 on which information such as a version (revision) is displayed, and an operation including a keyboard 261 and a mouse 262. The unit 26 is configured.

The CPU 21 executes a Java (registered trademark) virtual machine, an operating system (OS), and an application program.
The RAM 23 is specifically composed of a temporary storage memory such as an SRAM or a DRAM, and is used for temporarily storing data when the CPU 21 performs processing.
Specifically, the ROM 22 is configured by a flash memory, a nonvolatile memory such as a hard disk, and stores data and programs instructed by the CPU 21.

  In this example, an operating system (OS) stored in the storage unit 24 in the figure, middleware MW as software for constructing a Java execution environment, and a Java (registered trademark) language described in an object-oriented programming language A program such as an application described in the above is stored as a part of the software system. Then, when executing these programs, they are expanded on the RAM 23 as so-called computer (electronic computer) software.

The host device 20 having such a configuration is configured with the following features.
As described above, the software system includes an application program for executing processing according to the situation and a plurality of middleware for controlling communication with the card reader / writer 30.
In the host device 20, a plurality of middleware for communication control are collectively formed as a class library, and the class library for communication control is provided with a class for storing software system specific information.

Note that a class library is a program in which a program having a specific function is converted into a single “class” using an object-oriented programming language and a plurality of related classes are collected into one file.
In an object-oriented programming language, a template of an object group having common attributes and methods (data and procedures for manipulating this data) is called a “class”.
Since these “classes” can be used as parts of programs, it is possible to reduce the programming effort by collecting commonly used general-purpose items in a class library.
In the class library, it is possible to prepare a library that provides various functions such as file input / output, mathematical operation, and network.
Class libraries are classified by function in units called “packages”.

In the present embodiment, processing related to a class library for communication control will be described.
In this embodiment, the target communication control class library encapsulates the communication protocol with the target card reader / writer 30, and transmits an interface for performing command transmission and response reception for causing the card reader / writer 30 to function. The main purpose is provision.

In addition, the specific information can be exemplified by version information of a file providing a class library or an exported class library.
In addition to such version information, the unique information provides properties other than the class library version, such as copyright holder, date of creation, comment (internal user only, etc.), test version, etc. simultaneously or individually. It is possible.
In the present embodiment, version information, which is extremely important information when developing a communication control software system, will be described as an example.

Here, a file that provides the class library according to the present embodiment will be described.
FIG. 3 is a diagram for conceptually explaining the file providing the class library according to the present embodiment.

  The file 200 providing the class library is formed in a form including an execution program unit 201 and a class library export unit 202.

The execution program unit 201 has an execution function for outputting version information of a file or a class library to be exported when it is executed (when it is executed upon receiving an execution instruction).
Here, the execution upon receipt of an execution instruction is an icon indicating the file 200 displayed on the display device 25 by the user using the mouse 262 in the Windows (registered trademark) environment in the configuration of FIG. For example, operations such as double-clicking are included.

The class library export unit 202 includes a function for exporting a class library for communication control with the card reader / writer 30.
Here, exporting (or exporting) means providing an interface so that it can be used by other application software.

As an example of a file that provides a class library, a Java jar file is given. When the jar file is classified by purpose, the following three forms exist.
(1) Class library export only (2) Execution program only (3) Execution program + class library export

In the present embodiment, (3) an export program + class library export form is applied.
That is, in this embodiment, in addition to the export of the class library for communication control with the card reader / writer, which is the original purpose, an execution function for outputting version information is provided.

  These specific examples will be described in detail later. In this case, as an example, description will be made in association with a class library developed in Java (registered trademark) which is an object-oriented programming language.

Next, an example of a specific architecture of the main part of the higher-level device 20 will be described.
FIG. 4 is a diagram illustrating a specific architecture of the main part of the host device as the information processing apparatus according to the present embodiment.

The software system (block) 210 stores and executes a program for executing software.
As shown in FIG. 4, for example, the software system 210 includes an application unit 210A, a middleware unit 210B, an operating system (OS) unit 210C that controls the entire system, and a virtual machine (Java VM) 210D.
The software system 210 may include a boot program (BP) 220 that works when the system is started.

FIG. 4 shows an example of a Java execution environment in which a virtual machine (Java VM) is running on the OS, and it absorbs the difference between the interface (I / F) that works at system startup, the OS that controls the entire system, and the OS. A virtual machine (JavaVM) that provides a common platform, a class library that runs on the virtual machine (JavaVM), and an execution application that executes the purpose of use of the device.
Here, the OS, the virtual machine (Java VM), and the class library are operation programs to be updated.

The application unit 210A includes an object-oriented programming language source code generation unit 211, a parallel compiler 212, and an execution format unit 213.
The middleware unit 210B includes a communication control class library 214.
The communication control class library 214 includes a version information class “RevInfo.class”, a command transmission for functioning the card reader / writer 30 and a communication control “DevCtrl.class” for performing main control for receiving a response. Etc. " The class library 214 includes a class CLS that stores version information that is unique information of the software system.
The operating system unit 210C includes a host file unit 215, a utility unit 216, and a resident program unit 217.

The execution environment refers to an environment in which an application program is executed using object-oriented technology. In this embodiment, Java (registered trademark) is used as one of object-oriented technologies.
In the virtual machine 210D, for example, when an execution code (byte code) which is an intermediate language is executed, the virtual machine 210D is finally converted into a machine language code native to hardware and executed.

  The execution file generation of the software system 210 formed in this way will be described.

In the execution file generation process, first, the source code generation unit 211 creates a source code.
Compile the source code created by the compiler 212 with reference to the class library 214.
The execution form part 213 completes the execution file of the parallel application using the compilation result. The completed execution file is given to the OS (operating system) unit 210C.
The virtual machine 210D operates on the OS and interprets and executes the bytecode.

Heretofore, the configuration and function of the host device 20 have been specifically described.
Next, the configuration and function of the card reader / writer 30 will be described.

[Configuration and Function of Card Reader / Writer 30]
The card reader / writer 30 has a communication function with the host device 20 and a communication function with the IC card 40.
FIG. 5 is a diagram illustrating a configuration example of a signal processing system of a card reader / writer as an electronic apparatus device according to the present embodiment.

The card reader / writer 30 includes a CPU 31 that controls the entire card reader / writer 30 in an integrated manner, a ROM 32 that stores operation programs, initial values, parameters, and the like of the card reader / writer 30, a RAM 33 that functions as a working area for the CPU 31, An F (interface) 34 and a card I / F 35 are included.
The card reader / writer 30 is connected to the host device 20 via the host device I / F 34 and is configured to be communicable (wirelessly or wired) with the IC card 40 via the card I / F 35.
The card reader / writer 30 operates based on an information sequence command in accordance with a communication protocol with the host device 20 and has a function of transmitting and receiving an information sequence with the IC card 40 in accordance with the communication protocol.

The host device I / F 34 has a function of converting a signal sent from the host device 20 to the card reader / writer 30 into a TTL level signal and transferring it to the CPU 31.
Further, the signal from the CPU 31 is inversely converted and transferred to the host device 20. Communication between the host device 20 and the card reader / writer 30 is generally USB, RS232C, or the like.

The CPU 31 operates based on a command in an information sequence (command APDU) that conforms to a communication protocol (for example, USB) with the host device 20.
Then, the CPU 31 converts the command APDU into an information string that conforms to a communication protocol (for example, non-contact communication) with the IC card 40, and transmits this to the IC card 40.
That is, the CPU 31 converts the command APDU from the higher-level device 20 into a format (command TPDU) according to the communication protocol with the IC card 40.
The converted command TPDU is transmitted to the IC card 40 through the card I / F 35.

  On the other hand, when receiving a response from the IC card 40, the CPU 31 converts the response TPDU into a response APDU. The converted response APDU is transferred to the host device 20 through the host device I / F 34.

The card I / F 35 converts the command TPDU into a voltage or communication speed corresponding to the IC card 40 and transmits it to the IC card 40.
The card I / F 35 has a function of converting a signal received from the IC card 40 into a TTL level signal and transmitting it to the CPU 31.
Communication between the card reader / writer 30 and the IC card 40 is generally TTL level, non-contact communication, USB, or the like.

  The ROM 32 stores non-volatile data such as programs, while the RAM 33 functions as a working area for the CPU 31 and temporarily stores data.

[Specific execution example of class library]
As described above, in the present embodiment, the target class library encapsulates communication rules with the target card reader / writer, and an interface for performing command transmission and response reception for causing the card reader / writer to function. The main purpose is to provide
In this embodiment, the file providing the class library has an execution function for outputting version information in addition to the export of the card reader / writer communication control class library, which is the original purpose.
Specific examples of these will be described below.
Here, as an example, a description will be given in association with a class library developed in Java (registered trademark) which is an object-oriented programming language.

The Jar file is a file format that does not depend on the platform of the host device, in which a plurality of files constituting a Java (registered trademark) application are combined into one.
A class library developed in the Java language is generally provided by arranging a plurality of classes in a name space and collecting them in one file. This namespace is called a package.
The arrangement of the library in the package is realized in the form of a hierarchical structure using folders, and is generally distributed as a compressed file of the jar format while maintaining this folder structure. Note that jar is a form of file compression by the zip method.
An example is shown below. FIG. 6 is a flowchart showing basic processing for obtaining version information according to the present embodiment.

(Specific examples)
ICT3K5_3R6940Ctrl. jar
+ META-INF
| + MANIFEST. MF
+ Jp
+ Co
+ Nidec_sankyo
+ Crd
+ ICT3K5_3R6940
+ RevInfo. class (→ *)
+ DevCtrl. class
+ ICCardTransmitCtrl. class
+ SAMCardTransmitCtrl. class
+ UpdateFirmwareCtrl. class
+ <Omitted below>

In this example, similarly to the example described above, a plurality of Java class files having the extension “class”, that is, a class library is arranged in a package “jp / co / nidec_sankyo / crd / ICT3K5_3R6940”. This indicates that the files are grouped as a file named “ICT3K5_3R6940Ctrl.jar” (step ST1 in FIG. 6).
It is possible to store a plurality of packages in one jar file.
“MANIFEST.MF” is called a “manifest file”, and only one exists in one jar file.

  As described above, the target Java class library encapsulates the communication protocol with the target card reader, and provides an interface for performing command transmission and response reception for causing the card reader to function. And

In the present embodiment, a “RevInfo class” marked with (*), which is a class for acquiring version information, is created in this class library and added to the class library 214 (step ST2).
A main method is defined in the RevInfo class (step ST3).
And ICT3K5_3R6940Ctrl. When jar is executed (step ST4), this main method is called (step ST5).
Accordingly, the main method outputs version information (step ST6).

  In this jar file, a normal class library is stored in a package in a normal form. Therefore, except for the addition of the version output function, it is completely compatible with the normal version.

This has the following advantages over the normal method.
The version information of the jar file to be used can be acquired without going through other modules such as an application program.
In a Windows environment or the like, it can be executed directly by double-clicking the jar file. Therefore, there is no need to worry about the file search path. In other words, there is no worry of making an error such as obtaining version information of a jar file different from the intended one.
There is no need to use a jar file decompression software, binary editor, text editor or the like.

That is, according to the present embodiment, it is possible to eliminate errors due to indirect version confirmation by incorporating version information in the class library file itself.
Here, “indirect version confirmation” refers to version confirmation via information that is not originally related to the version, such as file update date and time.
In this embodiment, a message box appears when a file is directly clicked, and the version is displayed on the display device 25. This is the most direct version checking means that can be considered now objectively.

In the present embodiment, the card reader / writer has been described as an example of the communication control target. However, the present invention is not limited to the IC card reader / writer that reproduces or records information on the IC card described above, and magnetic information is recorded. It may be a magnetic card reader / writer that reproduces or records information on a magnetic card on which a magnetic stripe is mounted, or may be applied to other electronic device devices such as a card scanner and a card printer.
Also, it is possible to provide information on properties other than the version of the class library, such as the copyright holder and the creation date.
