The operation is started by an instruction from the operation control unit 106, and subsequent processing operations of the application execution unit 107 are continued or terminated by an instruction from the confirmation reception unit 111. The confirmation accepting unit 111 corresponds to the input unit 18 and provides the execution confirming unit 110 with an instruction to continue or terminate the application processing operation. The other functional blocks are the same as the functional blocks of the above-described first embodiment, and thus the same functional blocks will be denoted by the same reference characters and detailed description thereof will be omitted.

Next, the operation of the information terminal device 10 will be described. Note that the operation of the information terminal device 10 is the same as the flowchart described with reference to FIGS. 4, 5, and 8 in the above-described first embodiment.
The operation of the execution process indicated by reference numeral 16 is different. Therefore, in the second embodiment, only the operation of the information terminal device 10 in the execution process of step S16 in FIG. 4 will be described, and the other operations will not be described in detail.

First, in order to simplify the description of the operation of the information terminal device 10, an example of instruction data received by the information terminal device 10 will be described. FIG. 11 is an example of a format of the instruction data 200 received by the information terminal device 10.
This is data described in the ML format. In this format example, the information terminal device 10 displays a message to the user and then downloads the data held in the server 1 to send a data addition instruction to the address book of the information terminal device 10. Instruction data 20 to be executed
0 is shown.

The format includes a tag name surrounded by “<” and “>”, as in the first embodiment.
It can be divided into values enclosed by “<tag name>” and “</ tag name>”. The format includes five data blocks 205 to 209 by dividing the data into portions surrounded by “<tag name>” and “</ tag name>” based on the same tag name. . Data block 20
5 is a data block having a value “AddressBook” surrounded by a tag name “descriptorType”. The data block 206 includes the tag name “des
value in the address book
It is a data block having "add a business". The data block 207 is a data block having a value “AddToAddressBook” surrounded by a tag name “command”. The data block 208 is a data block having a value “item name, fax number, telephone number” surrounded by the tag name “parameters”. The data block 209 includes the tag name “signature
re ”surrounded by“ sZsiuHJmx40HwJ6 ”
JZzxkiwsq2 ”.

In step S14 of FIG. 4, the analysis unit 105 divides the format of the instruction data 200 into data blocks in the same manner as in the first embodiment, and And the value is analyzed, and the result is stored in the analysis result storage unit 108. Also,
In step S15, the operation control unit 106 determines the tag name “descripti” described in the data block 206.
The value “add ABC trading company to address book” enclosed by “on” is determined as an extracted message, and the extracted message data is stored in message storage unit 109.

Next, the information terminal device 10 according to the second embodiment performs an operation different from that of the first embodiment.
The execution process shown in step S16 of FIG. 4 will be described. FIG. 12 is a subroutine in which the information terminal device 10 shows a detailed operation of step S16 in FIG. Less than,
The execution process of the information terminal device 10 will be described with reference to FIG.

In FIG. 12, the operation control unit 106 calls the execution confirmation unit 110 and displays the execution confirmation screen on the display unit 1.
9 is displayed (step S161). This execution confirmation screen is used to confirm whether the application can be executed.
This is a screen to be displayed to the user.
When the extracted message is stored in the message storage unit 109 at 53, a part of the extracted message is replaced with the extracted message and displayed. FIG. 13 is a diagram showing an example of the execution confirmation screen displayed in step S161. In the example of the instruction data 200 described above, since “Add ABC Trading to the address book” is stored as an extraction message, a part of the execution confirmation screen is extracted from the extraction message EM.
Replaced by "Add ABC Trading to Address Book". In other words, execute the process of "Add ABC Trading to Address Book" as the above execution confirmation screen. Is it OK? Is displayed to urge the user to select either “Yes” or “No”. On the other hand, if a default message is stored in the message storage unit 109 in step S154, a default message set in advance is displayed on the execution confirmation screen. In other words, "Execute the" launch application "process as the above-mentioned execution confirmation screen. Is it OK? Is displayed to urge the user to select either “Yes” or “No”. Then, the process proceeds to the next step.

Next, the execution confirmation unit 110 checks the confirmation reception unit 1
Waiting for the execution confirmation instruction input from the user via 11,
It is determined whether to execute the corresponding application (step S162). Then, the above step S162
When the instruction to execute the corresponding application is input (when “Yes” is selected by the user on the execution confirmation screen in FIG. 13), the process proceeds to the next step S163
Proceed to.

Next, the application execution unit 107
The application corresponding to the instruction data 200 is activated and executed (step S163). In the case of the example of the instruction data 200 in FIG. 11 described above, the application execution unit 107 is described in the data block 207 based on the value “AddressBook” surrounded by the tag name “descriptorType” described in the data block 205. A value “AddToAddressBook” surrounded by a tag name “command” is started as a corresponding application, and an instruction to add data to an address book is executed. As the data to be added, the tag name “parapet” described in the data block 208 is used.
tag names and values ("ABC Trading" for "item name" and "06 for" fax number ")
"-1234-5679" and "06-1234-5678" for "telephone number" are given as data, respectively. Then, the information terminal device 10 ends the flow.

On the other hand, when an instruction not to execute the corresponding application is input in step S162 (when “No” is selected by the user on the execution confirmation screen in FIG. 13), the information terminal device 10 The flow ends without executing the application.

As described above, the information terminal device 10 adds, to the instruction data 200 transmitted from the server 1, an anchor character string or the like of a hypertext which is a link source of the instruction data 200 stored in the server 1. Regardless of the description content, the user can visually recognize the processing instruction content of the instruction data 200 on the display unit 19 and determine whether or not the processing can be executed.
00 can be omitted.

In the information terminal device 10, only highly-reliable instruction data can be executed based on a digital signature based on a known public key cryptosystem. For example, the instruction data 200 shown in FIG.
In the data block 209, the tag name “signature
re ”surrounded by“ sZsiuHJmx40HwJ6 ”
JZzxkiwsq2 "is described. This value is
This corresponds to an electronic signature based on the public key cryptosystem of the present invention.
This electronic signature is created using a secret key known only to a person who is qualified to create the instruction data 200. The information terminal device 10 corresponds to FIG.
Before the processing of step S13 of the above, the electronic signature is confirmed,
This electronic signature is verified with the public key corresponding to the secret key. Then, the information terminal device 10 advances the subsequent processing only for the instruction data 200 whose reliability has been confirmed by the verification of the electronic signature, and suspends the subsequent processing for the instruction data 200 whose reliability cannot be confirmed. Then, a predetermined warning message is displayed to the user. Therefore, if a malicious third party falsifies the message or the processing instruction content of the instruction data 200 to a false one, the processing is not executed.
In other words, the instruction data 20 in which the electronic signature is described
For 0, it can be expected that the message describing the processing instruction content is reliable information described by a qualified person.

In the above-described second embodiment, the operation in which the user determines whether or not to execute the process by inputting the message describing the processing content of the instruction data 200 to the user is performed. 10 may automatically determine whether the application can be executed. FIG.
Corresponds to step S1 in FIG. 4 described above when the information terminal device 10 automatically determines whether or not to execute an application.
6 is a subroutine showing a detailed operation of FIG.

In FIG. 14, the execution confirmation unit 110 determines the anchor character string of the link source hypertext of the instruction data 200 stored in the server 1 and the above-described step S1.
It is determined whether or not the extracted message stored in 53 matches the character string (step S165). If the execution confirmation unit 110 determines that the anchor character string matches the character string of the extracted message in step S165, the process proceeds to the next step S166. On the other hand, when the execution confirmation unit 110 determines in step S165 that the anchor character string does not match the character string of the extracted message, the process proceeds to the next step S167.

Next, if the execution confirmation unit 110 determines in step S165 that the anchor character string matches the character string of the extracted message, the application execution unit 1
07 starts and executes the application corresponding to the instruction data 200 (step S166). On the other hand, when the execution confirmation unit 110 determines that the anchor character string does not match the character string of the extracted message in step S165, the information terminal device 10 issues a predetermined warning message to the user without executing the corresponding application. The flow is displayed on the display unit 19 (step S167), and the flow ends.

As described above, by utilizing the fact that the user has selected the anchor character string of the hypertext of the link source of the server 1, when the anchor character string matches the extracted message, the application corresponding to the user , The execution of the application can be automatically determined.
Further, if a malicious person freely writes a false character string on the anchor, the anchor character string does not match the extracted message, and the application corresponding to the instruction data is executed by the information terminal device. Never. It goes without saying that an information terminal device can be implemented that executes a processing instruction only when the semantics have substantially the same meaning, rather than strictly matching character strings.

In the second embodiment, the instruction text in the XML format incorporates the explanation text indicating the processing contents, but the processing instruction information itself in the instruction data is
It is also possible to use a program code such as JAVA® language.
