[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a portable information processing apparatus such as an IC card, and in particular, is carried as a single unit when being carried and is configured to return a predetermined response to a predetermined command given from an external device when accessed. The present invention relates to a type information processing apparatus.
[0002]
[Prior art]
As electronic devices become smaller, the role played by portable information processing devices in the general society has become increasingly important. In particular, IC cards, which can be said to be representative of small portable information processing apparatuses, have been put into practical use in various fields in recent years, and are expected to be widely used in the future. A portable information processing device such as an IC card is usually carried with the body or a vehicle, and accesses from the outside by communicating with a reader / writer device connected to a personal computer or the like as necessary. Is possible.
[0003]
Currently, IC cards that are widely used are of a type with a built-in CPU, and access to the internal memory is possible only through the built-in CPU. For this reason, practically sufficient security is ensured. In general, the exchange between an IC card and an external device is a process in which a command is transmitted from the external device side to the IC card, and a response is transmitted from the IC card to the external device in response to this command. It is executed by repeating. In the IC card, an OS program for generally controlling basic functions as the information processing apparatus and an application program executed under the management of the OS program are prepared. The OS program and the application program are common in that they are programs that execute some processing based on a command given from an external device and return some response.
[0004]
Recently, the storage capacity of a memory built in an IC card has been increased, and an IC card storing a plurality of application programs in addition to an OS program has been widely used. In addition, a usage form in which such an application program can be stored in a writable non-volatile memory such as an EEPROM, and a necessary application program is additionally installed later has been widespread. As described above, when an IC card having a plurality of application programs is given a command to execute some processing, an application selection command is given to the IC card in advance to set a specific application in a ready state. Is executed. In general, an application that is in a ready state by an application selection command is called a “current application”. The application execution command given from the external device side is delivered and executed by the OS program to the application program that is in the ready state as the “current application” at that time.
[0005]
[Problems to be solved by the invention]
As described above, by installing a plurality of application programs in an IC card, one IC card can be used for various purposes. In addition, since a new application program can be additionally installed as necessary, a new application can be added. However, with a conventional IC card, it is difficult to add an additional function to an already installed application program. This is because, when one application program is installed, a program area, a data area, and the like for the application are fixed on the memory, and it becomes difficult to add a routine for a new function. Therefore, in the conventional IC card, when it is necessary to add an additional function to one application, the application program must be replaced with a new program, and a large revision work is required.
[0006]
Accordingly, an object of the present invention is to provide a novel configuration in which a new function can be easily added to a specific application in a portable information processing apparatus storing a plurality of application programs.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described based on the illustrated embodiments. FIG. 1 is a block diagram showing a configuration of a portable information processing apparatus (specifically, an IC card) 100 according to an embodiment of the present invention. The portable information processing apparatus 100 is carried as a single unit when being carried, and is connected to an external apparatus (specifically, a reader / writer apparatus) 200 when accessed. When a predetermined command is given from the external device 200, predetermined processing is performed in the portable information processing device 100, and the result is returned to the external device 200 as a response.
[0014]
The basic components of the portable information processing apparatus 100 are a storage unit 110, an arithmetic processing unit 120, and a transmission / reception unit 130, as shown. Various programs and data are recorded in the storage unit 110. The arithmetic processing unit 120 executes a command given from the external device 200 based on the program in the storage unit 110. Transmission / reception processing with respect to the external device 200 is performed by the transmission / reception means 130. Communication between the transmission / reception means 130 and the external device 200 may be performed by a contact method in which an electrode is physically brought into contact with each other to exchange electric signals, or an electromagnetic signal path is formed to exchange information. You may carry out by a contact system. The command given from the external device 200 is received by the transmission / reception means 130 and executed by the arithmetic processing means 120. After execution of the command, some kind of response is output from the arithmetic processing unit 120 and transmitted to the external device 200 by the transmission / reception unit 130. As described above, the communication between the portable information processing device 100 and the external device 200 is performed by alternately repeating the command transmission from the external device 200 and the response transmission from the portable information processing device 100.
[0015]
As shown in the figure, six areas are provided in the storage unit 110. The first area M1 stores an OS program for overall management of processing operations by the portable information processing apparatus 100. The arithmetic processing unit 120 basically executes various processes under the management of the OS program. A plurality of application programs are stored in the second area M2. In the figure, an example in which five types of application programs A to E are prepared is specifically shown. Normally, each of these application programs is a program used for a different purpose. For example, the program A is a program that performs processing for using the IC card as a hospital medical card, and the program B is a program that performs processing for using the IC card as a credit card. Is a program for performing processing for using this IC card as a library lending card, and so on.
[0016]
Data is stored in the third area M3. This data is data that is used by the OS program and each application program, and there is data that is commonly used by a plurality of programs and data that is unique to each application program. In practice, data specific to a specific application program is generally stored in an area adjacent to the storage area of the application program, but here, for convenience, data used in any application is The following description will be made assuming that the data is stored in the third area M3. The fourth area M4 is an area used as a work area when the arithmetic processing unit 120 performs various arithmetic processes, and the fifth area M5 is an area for storing current application designation information. It is. Here, the “current application” is one application selected from the plurality of application programs A to E stored in the second area M2, and is referred to as “the application currently selected”. become. In principle, the command given from the external device 200 is executed by this “current application” (as long as it is an execution command for a single application, as will be described later). The fifth area M5 can be handled as a part of the fourth area M4. However, since the fifth area M5 is an important component in the present invention, “current application designation information” is stored here. The fifth region M5 is defined as a dedicated region for this purpose.
[0017]
The first area M1 to the fifth area M5 described above are areas that are also used in conventional IC cards. The feature of the present invention is that a sixth area M6 is further provided, in which continuous execution rules R1 to R3 are stored, and a plurality of application programs prepared in the second area M2 are straddled. The point is that multiple routines can be executed. Here, the continuous execution rules R1 to R3 are rules indicating that a plurality of routines straddling a plurality of application programs should be executed in a predetermined order, as will be described in detail later. Can cause a plurality of applications to process a command given from the outside based on this continuous execution rule.
[0018]
In the embodiment shown in FIG. 1, the storage unit 110 is shown as one block. However, in reality, a non-volatile memory such as a ROM or EEPROM and a volatile memory such as a RAM are included in the IC card. Each of the areas M1 to M6 is provided in a plurality of memories as appropriate. In this embodiment, the first area M1 for storing the OS program is provided in the ROM (a part thereof may be provided in the EEPROM so that it can be rewritten). Also, a fourth area M4 used as a work area and a fifth area M5 for storing current application designation information are provided in the RAM. In this IC card, since all the electric power is supplied from the external device 200 side, when the communication with the external device 200 is completed and the external device 200 is disconnected, the contents of the fourth area M4 and the fifth area M5 are All will be lost. On the other hand, the second area M2 for storing application programs, the third area M3 for storing data, and the sixth area M6 for storing continuous execution rules are all provided in the EEPROM. Therefore, these pieces of information are held as they are even after the external device 200 is disconnected. Since the EEPROM can be rewritten or additionally written, any of the application program, data, and continuous execution rule can be corrected or added.
[0019]
The arithmetic processing means 120 is composed of an IC card CPU and has a function of executing the application programs A to E under the management of the OS program. As described above, the command given from the external device 200 is delivered to the arithmetic processing unit 120 via the transmission / reception unit 130. In general, commands can be classified into commands for causing an OS program to execute (hereinafter referred to as OS program execution commands) and commands for causing an application program to execute (hereinafter referred to as application execution commands). The type of command is usually recognized by the command name portion. If the given command is an OS program execution command, the arithmetic processing means 120 executes this based on the OS program in the first area M1, and the given command is an application execution command. If there is, it is executed based on the application program in the second area M2. A plurality of application programs A to E are stored in the second area M2, one of which is designated as the current application by the current application designation information stored in the fifth area M5. The given application execution command is executed by the current application.
[0020]
Thus, in the case of a conventional IC card, the application execution command is a command that is assumed to be executed by the application program currently specified as the current application, and is based on a single application program. It is a command. For example, when the application program A is designated as the current application, it is necessary to give an application execution command that can be interpreted and executed by the application program A from the external device 200. In other words, in a state where the application program A is designated as the current application, only application execution commands that can be interpreted and executed by the application program A can be executed.
[0021]
The basic point of view of the present invention is that even if the application program A is designated as the current application, for example, if processing using a routine in the application program B can be performed, the application is substantially This is based on the technical idea that the function of the program A can be expanded. In this way, if a command can be processed so as to straddle a plurality of applications, a task that cannot be handled by a single application can be processed by a cooperative operation of the plurality of applications.
[0022]
For example, suppose that the application program A is a program that performs processing for using this IC card as a hospital examination card. Here, when the case where this IC card is used as a medical examination card for a hospital using the external device 200 installed in the hospital, naturally, the application program A is designated as the current application, and based on the program A, the medical treatment is performed. Therefore, various processes are executed. Then, it is necessary to carry out the medical accounting process by chance, but it is assumed that the application program A itself does not have a function for totaling medical expenses for one month. In this case, with the conventional IC card, such a totaling process of medical expenses for one month cannot be executed inside the IC card. However, in the IC card according to the present invention, the application program B having such a totaling function is additionally installed, and the routine in the application program B is used for the process of totaling medical expenses for one month. If a continuous execution rule is prepared, it is possible to perform aggregation processing in the IC card. By adopting such a method, it is possible to handle the application program A as if it were expanded.
[0023]
In order to realize such processing, in the present invention, two commands are prepared as commands to be executed by the application program. The first command is a command to be executed by a single application designated as the current application, as in the past, and is referred to as a “single application execution command” here. On the other hand, the second command is a command peculiar to the present invention and is a command to be executed using a routine of an application program other than the application designated as the current application. It will be called "command". In the case of the above-described example, the process of totaling medical expenses for one month is performed by continuously generating an application program A designated as the current application and an application program B different from this (in the middle of processing, a response is generated). This can be realized by giving a “continuous execution command for multiple applications” to be executed.
[0024]
Eventually, three types of commands as shown in FIG. 2 can be given to the IC card according to the present invention. That is, there are three types of commands: “OS program execution command”, “single application execution command”, and “multiple application continuous execution command”.
[0025]
Here, the “OS program execution command” is a command executed by the OS program. For example, as shown in FIG. 2, “application selection command”, “application addition command”, “continuous execution rule addition command” (In fact, various other commands are also prepared). The “application selection command” is a command for designating a current application. For example, a command name (SELECT-APPLICATION PROG-A) and information (PROG-) for designating a specific application, such as “SELECT-APPLICATION PROG-A”. It becomes a command with A). When such an “application selection command” is given, the arithmetic processing means 120 writes “current application designation information” indicating the designated application program as the current application in the fifth area M5 based on the OS program. Execute. As in the above-described example, when the command “SELECT-APPLICATION PROG-A” is given, designation information (for example, “PROG” in the fifth area M5 indicates that “application program A” is the current application. -A ") is written.
[0026]
Note that the “current application designation information” is written into the fifth area M5 not only when an “application selection command” is given, but also when a specific current application is designated by an instruction from the OS program. Is also executed. Specifically, when the OS program is started, a specific application program designated by default is automatically designated as the current application, and “current application designation information” for designating the default application program is the fifth area M5. Is written to.
[0027]
On the other hand, the “application addition command” and “continuous execution rule addition command” are also “OS program execution commands” to be executed by the OS program. The “application addition command” is a command for additionally writing a new application program in the second area M2, and the object code of the program is given from the external device 200 side after the command name. Become. Based on the OS program, the arithmetic processing means 120 executes a process of writing the object code of the given new application into the second area M2 (usually an area composed of EEPROM). The “continuous execution rule addition command” is a command for additionally writing a new continuous execution rule in the sixth area M6, and a code indicating the continuous execution rule follows the command name. It will be given from the 200 side. Based on the OS program, the arithmetic processing means 120 executes a process of writing a code indicating a given new rule into the sixth area M6 (usually an area composed of EEPROM).
[0028]
Heretofore, an example of the “OS program execution command” used in the IC card according to the present embodiment has been described. Usually, various other “OS program execution commands” are prepared, but detailed description thereof is omitted here.
[0029]
On the other hand, the “single application execution command” is a command to be executed by a specific application program designated as the current application, and corresponds to a general application execution command in a conventional IC card. As in the example shown in the figure, predetermined commands are prepared for each application program, such as a program A command, a program B command, a program C command,. The specific commands to be prepared are determined depending on individual application programs. For example, a command for writing specific user data to the third area M3 or a specific user data for the third user M3 A command to read from the area M3, a command to search for specific user data, a command to execute a predetermined operation between given data and the read user data, and return the result as a response is there. Of course, it is also possible to prepare a common command for the programs A and B.
[0030]
In any case, this “execution command for single application” is a command that is executed by a single application program specified as the current application at the time of giving the command, and after execution, some response is external It is returned to the apparatus 200 (some data may be transmitted to the external apparatus 200, or a confirmation indicating that the process has been completed normally may be transmitted). If the application program designated as the current application cannot execute the given command (for example, the program B command is given in the state where the program A is designated as the current application). In the case), a response indicating an error is returned to the external apparatus 200.
[0031]
The “continuous execution command for multiple applications”, which is a feature of the present invention, is a command that cannot be executed only by a single application program designated as the current application at the time when the command is given. This is a command that can be processed by continuously executing other application programs. For example, after executing the process by the program A designated as the current application, a command that completes the process by executing another application program B is a feature of “continuous for multiple applications”. Run command ". If such a command is used, it is possible to handle the application program A as if a new function (the function of the program B) is added as viewed from the external device 200 side.
[0032]
However, in order for the arithmetic processing means 120 to execute such a “continuous execution command for multiple applications”, it is necessary to prepare a continuous execution rule in the sixth area M6 in advance. In other words, when the “multiple application continuous execution command” is given, the arithmetic processing unit 120 spans multiple applications based on the continuous execution rules stored in the sixth area M6. A process of executing a plurality of routines in a predetermined order is performed. Practically, a plurality of continuous execution rules are stored in the sixth area M6, and information specifying which continuous execution rule is used for the “multiple application continuous execution command” To be included. FIG. 1 shows a state where three rules R1, R2, and R3 are stored in the sixth area M6. In this case, the “continuous execution command for multiple applications” is shown in FIG. As shown in the lower column, three types of commands can be used: a command based on the rule R1, a command based on the rule R2, and a command based on the rule R3. If each command includes information indicating any one of the rules R1 to R3 in the command name part and the parameter part, the arithmetic processing unit 120 receives the command, It can be recognized which of the rules R1 to R3 should be processed.
[0033]
FIG. 3 is a block diagram illustrating an example of the rules R1 to R3. Based on such rules, the arithmetic processing means 120 executes the processing of “sequential execution commands for multiple applications” in a predetermined order.
[0034]
For example, the rule R1 is a rule indicating that the program B should be executed after the program A is executed. Usually, the programs A and B are composed of a set of routines for executing a command with some data and parameters. Therefore, in practice, the rule R1 includes a “program A command” to be given to the program A and a “program B command” to be given to the program B. In a conventional IC card, when a “program A command” is given to the arithmetic processing means 120 as an execution command for a single application, after the command is executed by the program A, the result is returned as a response to the external device 200. Will be returned to the side. On the other hand, in the IC card according to the present invention, when a “continuous execution command for multiple applications” based on rule 1 as shown in FIG. 3 is given, a predetermined “program” defined in rule 1 is provided. After the “A command” is delivered to the program A and executed, the predetermined “program B command” defined in the rule 1 is subsequently delivered to the program B and executed, and the result is a response. Is returned to the external device 200 side. That is, the predetermined process by the program A and the predetermined process by the program B are continuously performed, and the result of this continuous process is returned as a response. At this time, the parameter X generated by the execution of the program A is delivered to the program B. Eventually, using the result of the processing of program A, program B is subsequently executed.
[0035]
As in the example described above, the application program A is a program for performing processing for using an IC card as a hospital medical card, and the application program B is a program having a counting processing function for one month. When the medical expenses are aggregated by using a processing routine in the application program B, a process of passing the parameter X from the program A to the program B can be used as in the rule R1. In this case, if a command called “Aggregation command for medical expenses for one month” is defined as a “continuous execution command for multiple applications”, and a rule R1 for executing this command is defined as a continuous execution rule. Good. Specifically, first, the program A is caused to execute a read command for reading the medical cost list for one month, the read medical cost list is taken out as the parameter X, and then the program B is A rule R1 may be determined such that a summing command for summing up the parameters X is executed and the result is a response. Even if the program A originally does not have a function for performing the totaling process of the medical expenses for one month, only the part of the totaling process can be performed by using the routine of the program B. From the side, the program A can be handled as if a new counting function was added.
[0036]
The rule R1 shown in FIG. 3 is a rule for executing the two application programs A and B in order, but it is of course possible to define a rule for sequentially executing three or more application programs. Further, it is not always necessary to define the execution order in units of programs, and a continuous execution rule that defines the execution order for a specific routine in a certain application program may be defined. The rule R2 in FIG. 3 is an example in which an execution rule is defined for each routine in this way. That is, first, a specific routine c1 in the program C is executed (the routine c1 may be executed by giving some parameters as necessary), and the program D is obtained using the parameter X obtained as a result. Subsequently, a specific routine e2 in the program E is executed using the parameter Y obtained as a result, and a specific routine c2 in the program C is executed again using the parameter Z obtained as a result. Then, processing for returning the result as a response is performed.
[0037]
In general, since one application program is a collection of a plurality of routines, the continuous execution rule in the present invention is to execute a plurality of routines across a plurality of application programs in a predetermined order. It can be said that the rule indicates. Therefore, in the present application, the term “routine” is used not only to indicate each routine constituting the program but also to indicate the entire program that is a collection of routines.
[0038]
Note that the continuous execution rule does not necessarily need to be a rule that defines routines to be executed in a certain order at all times, and the routine to be executed subsequently changes based on parameters generated by the execution of one routine. Such rules may be used. In this case, a plurality of candidates are defined as routines to be executed subsequently, and a rule is set that determines which of the plurality of candidates should be selected and executed according to the parameter value. Just keep it. The rule R3 in FIG. 3 is an example of such a rule. In this example, three candidates of a program B, a program D, and a routine b8 in the program B are determined as a routine that follows the program E, and one of the candidates is determined based on the parameter X obtained by executing the program E. One candidate will be executed subsequently. Specifically, in the illustrated example, when the parameter X is positive, the program B is executed, when the parameter X is negative, the program D is executed, and when the parameter X is 0, the program B is executed. This routine b8 is executed.
[0039]
In FIG. 3, the continuous execution rules prepared in the present invention are shown as three examples. Of course, as the continuous execution rules, any rule can be freely defined. In addition, as shown in the upper column of FIG. 2, if a “continuous execution rule addition command” is prepared as one of the “OS program execution commands”, as described above, a new continuous command is created as necessary. Execution rules can be added and stored in the sixth area M6.
[0040]
In some cases, no substantial processing is performed by the application program that is the current application, and only processing by a completely different application program is executed. For example, when the program A is designated as the current application and the “continuous execution command for multiple applications” that is processed only by the routine in the program B is given, the program A does not perform any substantial processing. The substantial process is performed only by the program B without being involved. However, in this case as well, when viewed from the external device 200 side, when a command is given to the application program A that is apparently selected as the current application, it is handled as if a response to this is returned. In other words, the application program A functions as a processing window.
[0041]
From a practical point of view, it is expected that the frequency of using “multiple application continuous execution commands” is lower than the frequency of using “single application execution commands”. From this point of view, every time any command is given from the external device 200, the arithmetic processing means 120 determines whether the given command is a “single application execution command” or “continuous execution command for multiple applications”. It is inefficient to perform the process of recognizing each time. Therefore, in practical use, when the arithmetic processing unit 120 receives a command, the arithmetic processing unit 120 distinguishes between the command whether it is a “single application execution command” or a “multiple application continuous execution command”. For the time being, based on the application program specified as the current application at that time, a process that attempts to execute the given command is performed, and if an error occurs, the given command is It is only necessary to recognize the “continuous execution command” and execute the processing based on the continuous execution rules stored in the sixth area M6.
[0042]
The portable information processing apparatus according to the present invention has been described with respect to an example of an IC card. However, the present invention is not limited to an IC card and can be similarly applied to other portable information processing apparatuses.
[0043]
【The invention's effect】
As described above, according to the present invention, a new function can be easily added to a specific application in a portable information processing apparatus that stores a plurality of application programs.
