Description

  The present invention relates to a method in which a program stored in a terminal interprets and executes a script, and particularly records a script execution system, a script execution method, a script execution program, and a script execution program that ensure security when the terminal is lost. The present invention relates to a recording medium.

  In a conventional client-server system, a script is downloaded from a server, and a terminal device corresponding to a client executes the script.

  In order for the user to connect the terminal to the Internet, there is a cumbersome task of setting a connection to the Internet by connecting to a network device such as a router, and then setting an application such as a browser or mail on the terminal device.

  In order to alleviate this, the setting data of the Internet usage environment is recorded on a flexible disk and passed to the user, or the terminal device connected to the network starts a shared script on the server and is preinstalled. The application is automatically configured on the client.

  Further, there is an example in which the script itself is downloaded to a terminal device, and the terminal device executes the script to perform network connection setting or application setting (see Patent Document 1).

  Furthermore, there is an example in which a relay server that relays communication is provided with a script cache to a terminal device that does not have a script execution environment from the server, executes the script, and sends an execution result to the terminal device (Patent Document 2). reference).

  Furthermore, a technique for supplying a program to a terminal through a network, storing the program in a rewritable permanent storage area in the terminal, and starting and operating the program on the terminal by a user operation is widely disclosed and used. Yes. A typical example of such a technique is an i-appli technique disclosed by NTT DoCoMo, Inc.

  There is a script execution system as described below using the above-described technology.

  The script execution system program interprets data describing an instruction sequence to be processed (hereinafter, this data will be described as a script) and sequentially executes the data.

  In this technique, a program downloaded to a terminal is activated by specifying a location for acquiring a script to be executed first. The designation of the script to be executed first may be hard-coded in the execution program, or may be designated when the program to be executed is downloaded.

  The activated program accesses the location where the script is acquired through the network, acquires the script to be executed first from that location, holds it in the memory on the terminal, and interprets the instructions described in the script. The operation starts in the procedure of executing.

  Scripts include screen display scripts and internal processing scripts. At the beginning of the script, a code for identifying whether it is a screen display script or an internal processing script is described. The execution program distinguishes between the screen display script and the internal processing script at the time of reading or processing the script by this identifier.

  In addition, when the execution program reads and executes a script, if it is determined that the script is an internal processing script, only the processing instructions allowed to be described in the internal processing script are processed. Other processing instruction descriptions are ignored.

  On the other hand, when it is determined that the script is a screen display script, only processing instructions allowed to be described in the screen display script are processed, and other processing instructions are ignored. Some commands can be described in both scripts.

  Examples of processing that can be described in the internal processing script include an instruction to save data described in the script in the storage unit in the terminal, and data stored in the storage unit in the terminal. A command to read data stored in a permanent storage area in the terminal and store it in a memory as a variable, four arithmetic operations using a variable stored in the memory, character string processing, and the like.

  Examples of processing that can be described in the screen display script include an instruction for displaying data held in a memory as a variable, an input to be executed next when there is a user input, and an instruction to be executed next. There is a command to determine whether or not the input is requested by checking the user input.

  Thereby, another screen can be displayed or some other internal processing can be performed by a user's input. An example of an instruction that can be described in both scripts includes an instruction that specifies a script to be executed next.

  Regarding execution, the screen display script and the internal processing script can be executed in any order. For example, when a script to be executed next is included in the script as a command, the script is acquired, and the command written therein is interpreted and executed. As described above, the script execution system operates by acquiring scripts one after another and sequentially interpreting and executing instructions described therein.

  In addition, the script can be acquired and executed from what is stored in the terminal, or can be acquired from a server through the network and executed. As for where to specify the location from which the script is acquired, for example, the name of the script held in the terminal starts with “local: //”, and the name of the script existing on the network is “http: //” There are examples such as distinguishing by prescribing that the name starts with “/”.

  In this way, the service provider can provide the requested service to the user by describing the script and holding it in the server, and notifying the user of the address of the script.

  The types of instructions that can be executed are not limited to the above, but the types depend on the execution program and the device included in the mobile terminal.

  Next, an example of a service using this script execution system will be described.

  This service is a system that provides the weather forecast of the location to the owner of the portable terminal.

  The service provider describes, as an internal processing script, an instruction for acquiring position information of the mobile terminal, an instruction for notifying the server of the acquired position information, and an instruction for acquiring a script to be executed next from the server.

  When the user designates and starts the script, the position of the mobile terminal is notified to the service provider's server, and the service provider's server obtains the weather forecast for the area and uses it to display the screen. A script is generated and sent back to the mobile device. The mobile terminal that has received the returned screen display script displays the weather forecast on the screen of the mobile phone by processing the script.

In this way, the service provider can provide a service using the script execution system (Non-patent Document 1 and Non-Patent Document 2).

(First embodiment)
FIG. 1 is a block diagram of a terminal according to the present invention. The configuration in the best mode for carrying out the present invention is a configuration in which a terminal, 100, and server 200 are connected via a network.

  Referring to FIG. 1, a terminal 100 according to the present invention includes a central processing unit 101, a storage device 102, a timing device 103, an input device 104, an output device 105, and a communication device 106.

  The central processing unit 101 is a device having a function of reading an execution program from the execution program storage unit 111 and executing it, and is generally known as a CPU (Central Processing Unit) of a computer.

  The time measuring device 103 is a device capable of starting time measurement when activated by designating time, and notifying other devices of messages when the designated time has passed. For example, when minutes, seconds, etc. are designated, the timing is started, and when the designated time has elapsed, the central processing unit 101 can be notified by interruption or the like that the designated time has elapsed.

  In addition, when a timing stop request is received during startup, the timing can be stopped at that time. In other words, after canceling the timing after starting the timing, even if the specified time has elapsed from the time when the timing was started, this is not notified to the outside.

  The storage device 102 is a device that can store data and programs. The storage device 102 includes an execution program storage unit 111, a script storage unit 112, an initial script name storage unit 113, a final display screen script name storage unit 114, a time measurement storage unit 115, and a data storage unit 118. ing.

  The execution program storage unit 111 stores an execution program to be read and executed by the central processing unit 101. When the central processing unit 101 is activated, the terminal reads the execution program from the execution program storage unit and performs processing. Start.

  The script storage unit 112 is a storage unit that stores a script, and includes an internal processing script storage unit 116 and a screen display script storage unit 117.

  The internal process script storage unit 116 is a part that stores an internal process script, and can store one or a plurality of internal process scripts.

  The screen display script storage unit 117 is a part for storing a screen display script, and can store one or a plurality of screen display scripts.

  The data storage unit 118 is a part that can store various data along with script processing. For example, values described in the internal processing script can be stored in the data storage unit 118. Further, the data stored in the data storage unit 118 can be held on the memory as a variable.

  The final display screen script name storage unit 114 has a function of storing the name of the script. The timekeeping time storage unit 115 is a storage unit for storing timekeeping time, and can store a number such as “100” or “200”, or can store a character “stop”.

  The input device 104 is a device that can accept an input from a user. Examples include a keyboard, a touch screen, and a mouse.

  The communication device 106 is a device that can exchange information with other devices via a network. Examples of wired networks include Ethernet (registered trademark), telephone lines, and optical lines. Examples of wireless networks include a wireless local area network (LAN), a personal handyphone system (PHS), and a mobile phone network.

  FIG. 2 is a configuration diagram of a server in the present invention. Referring to FIG. 2, the server 200 according to the present invention includes a central processing unit 201, a storage device 202, an input device 203, an output device 204, and a communication device 205.

  The storage device 202 includes an execution program storage unit 211 and a script storage unit 212.

  When the server 200 is activated, it reads an execution program from the execution program storage unit 211 and starts processing. The script storage unit 212 can store one or more screen display scripts or internal processing scripts.

  Since the functions of the other devices are the same as those of the device having the same name as the terminal, description thereof will be omitted.

  Next, the operation in the first embodiment according to the present invention will be described.

  First, a description will be given of how the terminal 100 stores a script from the server 200 to the script storage unit 112 of the terminal 100.

  When the terminal 100 is activated, the central processing unit 101 reads an execution program from the execution program storage unit 111 and starts operation.

  First, the initial script name storage unit 113 is referred to. In the initial state, nothing is stored in the initial script name storage unit 113. In this case, the script is acquired from a location hard-coded in the execution program itself.

  In this operation example, assuming that the script 1 existing in the server is specified, the terminal 100 acquires the script 1 from the server 200 through the communication device 106 and starts execution.

  In this script, the script 4 is acquired from the script 2 from the server 200 and stored in the script storage unit 112 in the terminal 100 and the name corresponding to the stored script 2 is stored in the initial script name storage unit 113. Suppose an instruction to do is written.

  When this script is interpreted and executed, scripts 2 to 4 are sequentially acquired from the server 200 and stored in the internal processing script storage unit 116 and the screen display script storage unit 117 in the terminal 100.

  In this way, the script is stored in the terminal 100.

  In this state, when the terminal 100 is once terminated and restarted, the initial script name activation unit 113 stores the name corresponding to the script 2 stored in the terminal 100. The corresponding script is read from 100 and processing is started.

  Thus, since a plurality of scripts can be stored in the terminal 100, it is possible to form a script execution system that executes a service using only the scripts stored in the terminal 100 without communicating with the server 200.

  Next, a description will be given of a procedure in which the scripts are sequentially read and executed, and the security is ensured by the timing instruction in the scripts.

  3 and 4 are flowcharts showing the operation of the terminal 100. FIG.

  Referring to FIG. 3, the execution program first reads a designated script (S300). Next, it is determined whether the read script is a screen display script or an internal processing script (S301). If the script is a screen display script (YES in S301), the script name is stored in the final display screen script name storage unit 114 (S302).

  If the final display screen script name is already stored, it is overwritten.

  Next, the commands described in the script are sequentially acquired and executed. If the next command can be acquired (YES in S303), the command is acquired (S304).

  If this command is a command to read and execute a script next (YES in S305), the processing of the script currently being executed is interrupted, and the designated script is read and started (S300). .

  As described above, when the scripts are sequentially executed, the last screen display script storage unit 114 stores the name of the screen display script processed last.

  If the script being processed is an internal processing script and the command is a clocking start command (YES in S306), the time specified in the command is stored in the timer time storage unit (S307). ), Get the next instruction. Information already stored in the timer time storage unit is overwritten.

  If the script being processed is an internal processing script and is a timing stop command (YES in S308), it immediately requests the timing device 103 to stop timing, and a timer is stored in the timing time storage unit 115. Write a sign indicating stop. As for a sign meaning a time stop, for example, a character string “stop” may be used, or a character string “0” indicating time count 0 may be used.

  As a result of the processing, the timekeeping time storage unit 115 stores the timekeeping time designated by the last timekeeping instruction or a sign indicating timekeeping stop at the stage where the script is executed sequentially. become.

  On the other hand, if the instruction is other, the instruction is processed (S310).

  Then, when the execution program finishes executing the last script (NO in S303), the execution program refers to the time measurement storage unit 115. If the time is stored in the timekeeping time storage unit 115 (YES in S311), the designated time is instructed to the time measuring device 103 to request the start of timekeeping (S312).

  At this time, if a code indicating a stop is stored in the timekeeping time storage unit 115 (NO in S311), nothing is done.

  When the script processing and reading are completed, the execution program waits for user input or notification from the timer (S313).

  When the user input is accepted (NO in S314), the timer is instructed to cancel the timer timing, and the process associated with the user input is acquired by the screen display script (S316), and the process is started. To do.

  When the timer input is accepted (YES in S314), the authentication screen is displayed on the screen and the password input from the user is awaited (S315).

  If the correct password is entered here (YES in S317), the authentication screen is erased, the script name is extracted from the final display screen script name storage unit (S318), and the script is read and executed (S300).

  Since the last used screen display script name is stored in the final display screen script name storage unit 114, the last screen displayed to the user is displayed again to the user.

  On the other hand, if an incorrect password is input (NO in S317), no processing is performed and the next password input is awaited.

  As the method and system configuration used for password input and success / failure determination, any known technique may be used, and since it is widely known, details are not described.

With the configuration and operation as described above, a builder who builds a system using the script execution system simply specifies the time and describes the timekeeping command in the internal processing script. It is possible to provide a system that does not perform processing until input. As a result, it is possible to easily provide a system with a low risk of misuse of the system when the terminal is lost.
(First embodiment)
As an embodiment of the present invention, an example of an internal processing script and an example of a screen display script are shown in FIGS. 5 and 6, respectively. In these examples, the script is written in XML (extensible Markup Language) format.

  When the first element name next to the XML declaration is “script”, it indicates an internal processing script, and when it is “html”, it indicates a screen display script. The portion indicated by (1) in FIG. 5 is a time measuring instruction, and in this example, 300 seconds are indicated. (2) in FIG. 5 represents a process of reading data stored in the terminal 100 from the data storage unit 118 and setting it as a variable. In this example, it is assumed that mail data is read.

  (3) in FIG. 5 designates a script name to be read and processed next. In this example, it is assumed that the screen display script shown in FIG. 6 is designated.

  That is, in this internal processing script, 300 seconds is specified as the timekeeping time, the value in the storage device of the terminal 100 is read as a variable, and the processing moves to the screen display script.

  Also, (4) in FIG. 6 is a command for displaying a title line at the top of the screen. In (5) of FIG. 6, a part directly written as a character string in the <body> element, that is, “From:”, “Subject:”, etc. is displayed as it is on the screen. The part designated as the <output> element designates that data designated by the ref attribute is read and displayed on the screen. The <br/> element designates a line break at that location.

  When the internal processing script and the screen display script are specified as described above, a service for displaying the mail data stored in the terminal can be executed.

If the user's input is not accepted while the mail is being displayed, the authentication screen is displayed on the screen, and the mail content is not displayed on the terminal, thus ensuring security.
(Second Embodiment)
The second embodiment of the present invention is different from the first embodiment as follows.

  In the first embodiment described above, the configuration of the authentication screen is hard-coded in the execution program. In the second embodiment, the authentication screen and the like are also configured by a screen display script, so that customization of the authentication screen can be provided to the system developer.

  The configuration of the second embodiment is different only in that an authentication screen display script storage unit 119 is provided in the script storage unit 112 on the terminal 100 side.

  FIG. 7 shows the configuration on the terminal 100 side in the second embodiment, and only the differences from the previous embodiment are described.

  Referring to FIG. 7, in the terminal configuration in the second embodiment, an authentication screen display script storage unit 119 is newly provided.

  Next, the operation of the second embodiment will be described. In the operation of the second embodiment, the terminal 100 operates according to the flowchart of the operation of the terminal in the second embodiment of the present invention shown in FIGS.

  Here, the same number is attached | subjected to the step which performs the process same as the operation | movement of the terminal in 1st Embodiment, and the same operation | movement shall be performed.

  In the operation of the second embodiment, on the terminal 100 side, an operation for processing a timing start command (S400 to S402 in FIG. 9) and an operation for acquiring an authentication screen display script and executing authentication (FIG. 10). The processing content of S410) is different from that of the first embodiment.

  Specifically, in the second embodiment, the clocking start command stores a clocking time and an authentication screen display script name.

  First, the operation (S400 in FIG. 9) for processing the timing start command will be described.

  The execution program that processes this timing start command acquires a script using the designated authentication screen display script name (S400), and verifies whether the script is a screen display script (S401).

  Then, if the acquired authentication screen display script is a screen display script, it is stored in the authentication screen display script storage unit 119 and then stored in the time measurement storage unit 115 ( S402).

  As described above, regarding the acquisition of the authentication screen script, the type of script is determined, and the authentication screen script and the time count are stored.

  Next, an operation (S410) in a case where the authentication screen display script is acquired and the authentication is executed after receiving the timing notification will be described.

  The operation of the terminal 100 when receiving the timekeeping notification in the second embodiment is to acquire the authentication screen display script from the authentication screen display script storage unit 119 after the elapsed time stored in S402. The authentication is executed, and after the authentication is obtained (S317), the final screen display script is executed to display the final screen (S318).

  In the final display screen script name storage unit 114, the last used screen display script name is stored as in the first embodiment. The displayed display screen is displayed again to the user.

By configuring and operating as described above, it is possible for the developer to customize the authentication screen, and by acquiring the script and verifying that it is a screen display script, it is possible to make a mistake. This prevents an operation in which the internal processing script is stored and the authentication screen is not displayed.
(Second embodiment)
As an embodiment of the present invention, an example of an internal processing script is shown in FIG. 11, and an example of an authentication screen display script is shown in FIG.

  (6) in FIG. 11 is a time measurement command, in which 300 seconds are specified as the time measurement time, and “http://xxx.yyy.com/password.xml” is designated as the acquisition source of the script for displaying the authentication screen.

  The content of the script that can be acquired from the position is the authentication screen script illustrated in FIG.

  Here, when the internal processing script in FIG. 11 acquires the authentication screen script shown in FIG. 12 from the acquisition source, it is determined whether or not it is a screen display script, and it can be confirmed that it is a screen display script. In this case, the authentication screen display script storage unit 119 shown in FIG.

  Further, by storing 300 seconds of the time measured in the internal processing script in FIG. 11, the authentication screen script shown in FIG. 12 is executed 300 seconds after the input from the user is lost. It has become so.

  When this authentication screen script is executed, the text below <body> shown in FIG. 12 is displayed.

  That is, as shown in the authentication screen script of FIG. 12, the words “Specified time ... please input” are written as the words displayed on the screen.

  By changing this wording, the service provider can easily prompt the user to operate the terminal, and in such an authentication screen display script, the characters displayed on the screen can be easily changed. Can be customized.

  Further, by performing authentication while notifying the user, the security of the terminal 100 can be protected.
