Description

  The present invention relates to activation control of an application program that runs on a mobile terminal.

  Conventionally, various methods for detecting that an application program has been illegally altered have been developed. Japanese Patent Application Laid-Open No. 2004-228561 describes a technique for checking whether an application is illegally changed by a check mechanism built in the application when executing an application program.

Japanese Laid-Open Patent Publication No. 4-149653

  Patent Document 1 aims to ensure the security of an application that operates on a terminal in a closed environment that is not connected to the outside. On the other hand, at present, the network environment is improved, and portable terminals are widely used in addition to personal computers as terminals for executing applications.

  In an environment where a terminal for executing an application is connected to a network, the application may be distributed via the network. At this time, since it is easy to download the application via the network, there is a possibility that it may lead to security damage such as damage caused by a computer virus or unauthorized rewriting of the application program. In particular, since security measures for portable terminals tend to be delayed as compared with general computers such as personal computers and servers, a useful technique that can increase safety is desired.

  SUMMARY An advantage of some aspects of the invention is that it provides a technical technique capable of safely executing an application program that runs on a mobile terminal.

  The application activation control method according to the present invention compares the attribute information acquired from the application program main body with the attribute information of the application program held in advance in the mobile terminal, and permits the activation of the application program if they match. .

  According to the application activation control method according to the present invention, it can be seen that when the application program is illegally rewritten, the attribute information is different from that held in advance. As a result, it is possible to detect that there has been unauthorized rewriting, and thus it is possible to safely start the application program.

  The storage unit 140 includes a storage device such as an HDD, and stores an application program 141, an application activation control unit 142, and application meta information data 143.

  The application program 141 is a program that provides application functions used by the user of the mobile terminal 100. For example, there are programs such as a customer information search program, a product management program, a schedule management program, and an e-mail client program. For convenience of explanation, one or more application programs are collectively referred to as application programs 141, but the number of application programs 141 may be arbitrary.

  The application activation control unit 142 is a functional unit that controls activation of the application program 141. When the user of the mobile terminal 100 tries to start the application program 141, the application start control unit 142 receives the start instruction and determines whether or not the application start program 141 may be started according to the determination criteria described later. . If the determination criteria are not met, the user cannot start the application program 141.

  The application activation control unit 142 includes an AP automatic update check unit 1421, an AP meta information check unit 1422, and a terminal information check unit 1423. These functional units can be configured integrally as a part of the application activation control unit 142, or can be configured as separate program modules linked to the application activation control unit 142. Details of these functional units will be described later with reference to FIG.

  The application meta information data 143 is data describing attribute information of each application program 141. An example of the application meta information data 143 will be described later with reference to FIG.

  FIG. 4 is a diagram illustrating a configuration and data example of the application meta information data 143 held by the mobile terminal 100. The application meta information data 143 is a data file for holding the attribute information of the application program 141 on the portable terminal 100 side, and includes an application ID field 1431, a version field 1432, a size field 1433, an update date / time field 1434, and an application name field 1435. Have

  The application ID field 1431 holds identification information for identifying each application program 141.

  The version field 1432 holds version information of the application program 141 identified by the value of the application ID field 1431.

  The size field 1433 holds a numerical value indicating the file size of the program file of the application program 141 identified by the value of the application ID field 1431.

  The update date / time field 1434 holds the date / time when the program file of the application program 141 identified by the value of the application ID field 1431 was last updated. This field corresponds to the date and time when the application file 210 is uploaded on the server 200.

  The application name field 1435 holds the name of the application program 141 identified by the value of the application ID field 1431.

  FIG. 5 is a diagram showing a configuration and data example of the application meta information database 220 held by the server 200.

  The entity of the application file 210 is the same as the application program 141 executed by the mobile terminal 100, so the fields held in the application meta information database 220 are the same as the application meta information data 143 except for the registration status field 226.

  The registration status field 226 holds a value indicating whether or not the application file 210 identified by the value of the application ID field 221 is registered in the server 200. This field is provided for convenience for the operator of the management terminal 400 to manage the application program. An application whose field is “registered” can be downloaded from the mobile terminal 100, and an application whose field is “deleted” cannot be downloaded.

  When the application program 141 is illegally rewritten on the mobile terminal 100, a difference may occur between information held in the application meta information database 220 and information held in the application meta information data 143. Using this, the application activation control unit 142 of the mobile terminal 100 detects unauthorized rewriting of the application program 141. Details will be described later with reference to FIG.

  The configuration of each device of the network system 1000 has been described above. Next, the operation procedure of each device will be described.

FIG. 6 is a diagram illustrating a procedure for registering an application program from the management terminal 400 to the server 200. Hereinafter, each step of FIG. 6 will be described.
(FIG. 6: Step 1: Management terminal 400 side)
The operator of the management terminal 400 uses the management terminal 400 to upload a program file of an application program to be registered in the server 200 to the server 200. At this time, the application meta information of the application program is also uploaded.
(FIG. 6: Step 1: Server 200 side)
The AP update unit 261 of the server 200 receives the program file and stores it as the application file 210. Further, the AP update unit 261 receives application meta information and stores it in the application meta information database 220. The AP update unit 261 may check whether or not the application program and its meta information are created according to a predetermined rule as necessary. When the registration is completed, the AP update unit 261 changes the value of the registration status field 226 to “registered”. When an old version application is updated to the latest version, the value of the old version registration status field 226 may be changed to “deleted”.

(Figure 6: Step 2: Query registration status)
The management terminal 400 inquires of the server 200 about the registration status of the application program using the value of the application ID field 221 as a key. The search processing unit 262 of the server 200 confirms the registration status based on the value of the registration status field 226 of the application meta information database 220 and returns it to the management terminal 400.
(Figure 6: Step 3: Registration completed)
When the registration of the application program is completed, the AP update unit 261 returns a message to that effect to the management terminal 400. When the management terminal 400 receives the reply, registration of the application program is completed.

FIG. 7 is a diagram illustrating an operation procedure when the application program 141 is activated on the mobile terminal 100. Hereinafter, each step of FIG. 7 will be described.
(FIG. 7: Step 1: mobile terminal 100 side part 1)
The user of the mobile terminal 100 accesses the server 200 using the mobile terminal 100 and requests to download the application file 210 using the value of the application ID 221 as a key. The AP automatic update check unit 1421 transmits the request to the server 200.
(FIG. 7: Step 1: Server 200 side)
The search processing unit 262 of the server 200 searches for the application meta information in the application meta information database 220, specifies the corresponding application meta information and the application file 210, and transmits them to the mobile terminal 100.

(FIG. 7: Step 1: mobile terminal 100 side part 2)
The AP automatic update check unit 1421 of the portable terminal 100 stores the application file 210 and application meta information downloaded from the server 200 in the storage unit 140 as an application program 141 and application meta information data 143, respectively.
(FIG. 7: Step 2: Generate attribute information)
The user of the mobile terminal 100 instructs the mobile terminal 100 to start the application program 141 downloaded from the server 200. At this time, the application activation control unit 142 is notified of the application ID of the application program 141 instructed to be activated via a screen shown in FIG. The AP activation control unit 142 receives the activation instruction. The AP meta information check unit 1422 accesses the application program 141 instructed to start, and generates attribute information of the application program from the program body.

(FIG. 7: Step 2: Generate attribute information: Supplement 1)
The attribute information of the application program 141 generated by the AP meta information check unit 1422 in this step can be obtained directly from the program body itself of the application program 141. For example, the file size of the program file, the update date and time of the program file, and the like correspond to this. As long as other attribute information can be acquired, the file size and the update date / time are not limited.
(FIG. 7: Step 2: Generate attribute information: Supplement 2)
This step has the significance of acquiring the attribute information of the application program 141 at the current time. That is, if the application program 141 is illegally rewritten, it is assumed that the attribute information is different from the attribute information at the time of downloading. We decided to acquire information.

(FIG. 7: Step 3: Match attribute information)
The AP meta information check unit 1422 compares the attribute information generated from the application program 141 main body in step 2 with the attribute information in the application meta information data 143 acquired from the server 200 in advance. Here, it is assumed that the file size acquired in step 2 and the size field 1433 are compared with the update date / time acquired in step 2 and the update date / time field 1434, respectively.
(Figure 7: Step 4: Start permission)
If the result of step 3 indicates that the two match, the AP meta information check unit 1422 permits the application program 141 to be activated. The AP activation control unit 142 activates the application program 141.
(Fig. 7: Step 5: Unable to start)
If the result of step 3 indicates that the two do not match, the AP meta information check unit 1422 does not allow the application program 141 to be activated. The AP activation control unit 142 displays an error message on the screen of the mobile terminal 100 and notifies the user of the mobile terminal 100 that the activation is impossible.

  FIG. 8 is a diagram illustrating an operation screen image for starting the application program 141 provided by the application start control unit 142. Hereinafter, each screen shown in FIG. 8 will be described.

  The user of the mobile terminal 100 causes the mobile terminal 100 to display a list of application programs 141 on the main menu screen via an application list screen, an application search screen, or the like.

  The user of the mobile terminal 100 selects one from the list of application programs 141 and instructs the mobile terminal 100 to start the application program 141.

  The AP meta information check unit 1422 of the application activation control unit 142 executes the processing procedure described with reference to FIG. 7 for the application program 141 instructed to be activated, and determines whether to permit the activation.

<Embodiment 1: Summary>
As described above, in the first embodiment, when receiving an activation instruction for the application program 141, the application activation control unit 142 acquires attribute information from the program main body of the application program 141 and acquires it from the server 200 in advance. The application meta information data 143 is compared. As a result, when the application program 141 on the portable terminal 100 is illegally rewritten, the attribute information is assumed to be different from that described in the application meta information data 143. be able to. In other words, this can be prevented before the application program 141 that has been illegally rewritten is inadvertently activated.

  In the first embodiment, the application activation control unit 142 different from the main body of the application program 141 checks the attribute information. Thereby, it can be considered that security can be improved as compared with the case where the application program 141 itself checks. That is, the application program 141 has many opportunities to be downloaded from the outside, and it can be said that there is a high possibility that the application program 141 is illegally rewritten accordingly. Therefore, in the first embodiment, a check mechanism different from the check mechanism by the main body of the application program 141 is provided. Therefore, it was decided to improve security.

<Embodiment 2>
In the second embodiment of the present invention, in addition to or separately from the operation described in the first embodiment, an operation procedure for checking whether or not the application program 141 is the latest version when the application program 141 is activated. Will be explained. Since the configuration of the network system 1000 and each device is the same as that of the first embodiment, the following description focuses on the differences.

FIG. 9 is a diagram showing an operation procedure for checking whether or not it is the latest version when starting the application program 141 on the mobile terminal 100. Hereinafter, each step of FIG. 9 will be described.
(FIG. 9: Step 1: mobile terminal 100 side)
The user of the mobile terminal 100 instructs the mobile terminal 100 to start the application program 141. At this time, the application activation control unit 142 is notified of the application ID of the application program 141 instructed to be activated via the screen of FIG. The AP activation control unit 142 receives the activation instruction. The AP automatic update check unit 1421 inquires of the server 200 about the value of the latest version of the application program 141 instructed to start, using the value of the application ID 221 as a key.
(FIG. 9: Step 1: Server 200 side)
The search processing unit 262 of the server 200 acquires the value of the version field 222 corresponding to the designated application file 210 from the application meta information database 220. When there are a plurality of records having the same value in the application ID field 221, the value in the version field 222 is changed for the record in which the value in the update date / time field 224 is the latest among the values in the registration status field 226 that are “registered”. get. The search processing unit 262 returns the value to the mobile terminal 100.

(Figure 9: Step 2: Compare version information)
The AP automatic update check unit 1421 of the mobile terminal 100 receives the value of the version field 222 acquired from the server 200 in step 1 and the value of the version field 1432 in the application meta information data 143 stored in the storage unit 140 in advance. Compare
(Figure 9: Step 3: Download the latest version)
If the result of step 2 indicates that the value of the version field 222 held by the server 200 is a newer version, the AP automatic update check unit 1421 downloads the latest version of the application program from the server 200. To do. The download procedure is the same as step 1 in FIG.
(Figure 9: Step 4: Start application)
If the result of step 2 indicates that the value of the version field 222 held by the server 200 is the same as the value of the version field 1432, the AP automatic update check unit 1421 permits the application program 141 to start. To do.

<Embodiment 2: Summary>
As described above, in the second embodiment, when the application activation control unit 142 receives an activation instruction for the application program 141, the application activation control unit 142 acquires the value of the version field 1432 corresponding to the application program 141, and the server 200 holds the value. It is compared with the value of the version field 222 that is present. As a result, when the version of the application program 141 held by the mobile terminal 100 is not the latest version, it can be automatically updated to the latest version, so that it is not necessary to provide a version upgrade mechanism in the application program 141 main body, and development The burden can be reduced.

  In the second embodiment, the method described in the first embodiment can be used in combination. For example, after downloading the latest version of the application program 141, the attribute information may be checked by the same method as in the first embodiment.

<Embodiment 3>
In the third embodiment of the present invention, an example of an operation procedure using the procedure described in the first and second embodiments will be described. In addition, an operation for determining whether to start the application program 141 in consideration of the device state of the mobile terminal 100 is newly provided. Since the configuration of the network system 1000 and each device is the same as that of the first embodiment, the following description focuses on the differences.

FIG. 10 is a diagram illustrating a procedure for starting the application 141 on the mobile terminal 100 in the third embodiment. Hereinafter, each step of FIG. 10 will be described.
(FIG. 10: Steps S1001 to S1002)
The portable terminal 100 activates the application activation control unit 142 and displays the main menu illustrated in FIG. 8 on the screen (S1001). The user of the portable terminal 100 selects an application list from the main menu and selects an application program 141 to be activated (S1002). Here, it is assumed that application A is selected.
(FIG. 10: Step S1003)
The terminal information check unit 1423 checks the remaining battery level of the mobile terminal 100. If the remaining battery level is less than the prescribed remaining level, the activation of the application is not permitted, a message to that effect is displayed on the screen, and the process returns to step S1001. If the remaining battery level is equal to or greater than the specified remaining level, the process proceeds to step S1004.
(FIG. 10: Step S1003: Supplement)
The specified value of the remaining battery level to be checked in this step may be stored in advance in an appropriate storage area in the storage unit 140.

(FIG. 10: Step S1004)
The terminal information check unit 1423 checks whether or not the mobile terminal 100 can communicate with the base station 300. For example, it is checked whether or not the mobile terminal 100 is within a communicable range. If communication is possible, the process proceeds to step S1005, and if communication is not possible, the process proceeds to step S1008.
(FIG. 10: Step S1004: Supplement)
This step has significance as preprocessing for determining whether or not to execute processing for inquiring the server 200 for the latest version of the application program. This is because when the mobile terminal 100 cannot connect to the network, the server 200 cannot be inquired about the latest version.
(FIG. 10: Step S1005)
The application activation control unit 142 executes the procedure described with reference to FIG. 9 of the second embodiment, and inquires the server 200 about the latest version of the application A.

(FIG. 10: Step S1006)
If a newer version than the application A held by the mobile terminal 100 exists in the server 200, the process proceeds to step S1007. If the mobile terminal 100 already holds the latest version, the process proceeds to step S1008.
(FIG. 10: Steps S1007 and S1011)
The application activation control unit 142 executes the procedure described with reference to FIG. 9 of the second embodiment, and downloads the latest version of the application A from the server 200 (S1007). When the download is completed, the application program is activated (S1011).
(FIG. 10: Steps S1007 and S1011: Supplement)
Here, it is assumed that the application downloaded from the server 200 is the latest legal version and has not been illegally rewritten, and the application A is immediately activated without checking the attribute information. Alternatively, after step S1007, the process may return to step S1001 to prompt the user to start application A again.

(FIG. 10: Steps S1008 to S1009)
The application activation control unit 142 executes the procedure described in FIG. 7 of the first embodiment, and checks whether the attribute information of the application A matches the attribute information on the server 200 (S1008). If they match, the process proceeds to step S1011. If they do not match, the process proceeds to step S1010 (S1009).
(FIG. 10: Step S1010)
The application activation control unit 142 displays a message on the screen indicating that the application A cannot be activated because it has been illegally rewritten.
(FIG. 10: Step S1011)
The application activation control unit 142 activates the application A.

<Embodiment 3: Summary>
As described above, in the third embodiment, when the application activation control unit 142 receives an activation instruction for the application program 141, the application activation control unit 142 checks whether the mobile terminal 100 can communicate with the network. Check and omit the latest version check if communication is not possible. As a result, it is possible to avoid a situation in which the version check is executed in an environment where communication is not possible and the user is kept waiting, and the usability of the mobile terminal 100 can be improved.

  In the third embodiment, when the mobile terminal 100 cannot communicate, the attribute information is checked according to the procedure described in the first embodiment. Thereby, even when the application program 141 may not be the latest version, it is possible to detect unauthorized rewriting by checking the attribute information, so that security can be improved. In addition, even when the mobile terminal 100 already holds the latest version of the application program 141, the same procedure can be performed as in the first embodiment to achieve the same effect.

<Embodiment 4>
In the first to third embodiments, the example in which the file size and update date / time of the application program 141 are acquired from the program main body and compared with the application meta information data 143 has been described. In the fourth embodiment of the present invention, an example in which other attribute information is acquired from the program body of the application program 141 and compared with the application meta information data 143 will be described. The following examples can be considered as other attribute information.

(Example of attribute information 1: file hash value)
The application meta-information database 220 of the server 200 and the application meta-information data 143 of the mobile terminal 100 store hash values that can be calculated from the file body of the application program 141 using the size fields (223, 223, 1433) and the update date / time fields (224, 1434) or in place of them. Upon receiving an activation instruction for the application program 141, the AP meta information check unit 1422 calculates the hash value of the program body of the application program 141, and the hash value of the application program 141 held in the application meta information data 143 Compare.

(Example of attribute information 2: embedded key value)
A unique key value that can identify the application is embedded in the program body of each application file 210 and application program 141. The application meta information database 220 of the server 200 and the application meta information data 143 of the mobile terminal 100 have the key values of the size field (223, 1433) and the update date / time field (224, 1434) described in the first to third embodiments. In addition to or in place of these. When the AP meta information check unit 1422 receives an activation instruction for the application program 141, the AP meta information check unit 1422 acquires a key value from the program main body of the application program 141, and the key value of the application program 141 held in the application meta information data 143.
