Like reference numerals are used for like elements in describing each drawing.

Hereinafter, embodiments according to the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a schematic block diagram of a system for blocking execution of a pirated mobile app according to an embodiment of the present invention. Referring to FIG.

Referring to FIG. 1, a system 100 according to an embodiment of the present invention includes a server 110 and a terminal device 120.

The server 110 is a server for managing a market where a mobile app can be purchased / sold. The terminal device 120 can be moved by being carried by a user, and can be installed / Equipment. As an example, the terminal device 120 may be a smart device such as a smart phone, a tablet PC, or the like.

In detail, the server 110 includes a communication unit 111, a registration unit 112, and a control unit 113, and the terminal device 120 includes a communication unit 121 and a control unit 122.

The server-side communication unit 111 communicates with the terminal-side communication unit 121 (this communication can be performed through a covert channel), and each of the controllers 113 and 122 communicates with the communication units 111 and 121 And controls the operation of the other server 110 and the terminal device 120 as a whole. Then, the registration unit 112 registers information related to determination of whether or not the mobile app is normally purchased, which will be described below.

In addition, FIG. 2 is a diagram showing a general flow of a procedure for registering copyright information for blocking the execution of a pirated mobile app in the server 110 according to an embodiment of the present invention. FIG. FIG. 2 is a diagram illustrating an overall flow of a method for blocking execution of a pirated mobile app according to an exemplary embodiment.

Hereinafter, the function of each component and the process performed for each step will be described in detail with reference to FIG. 1 to FIG.

First, referring to FIG. 1 and FIG. 2, a procedure for registering copyright information for blocking the execution of a pirated mobile app on the server 110 will be described below.

In step S202, the terminal device 120 transmits a purchase request message for a specific mobile app (via the communication unit 121).

The server 110 receiving the purchase request message transmits the mobile application requested to be purchased through the communication unit 111 to the terminal device 120 in step S204 and transmits the purchase request message to the terminal device 120 (Hereinafter, referred to as "user information of the terminal apparatus" for convenience of explanation) in the registering unit 112. [ Accordingly, the terminal device 120 obtains the mobile application from the outside.

The mobile app to be transmitted to the terminal device 120 is a mobile app in which copyright information (for example, watermark or forensic mark) is not inserted. Hereinafter, for convenience of explanation, a mobile app in which copyright information is not inserted will be referred to as "original mobile app ".

Next, in step S208, the terminal device 120 receiving the original mobile app via the communication unit 121 inserts the new copyright information into the original mobile app. Hereinafter, for the sake of convenience of explanation, a case where the copyright information is inserted in the original mobile app will be referred to as "mobile app ".

Then, in step S210, the terminal device 120 transmits the inserted copyright information to the server 110 via the communication unit 121. [ In this case, the user information of the terminal device can be transmitted to the server 110 together. Although not shown in FIG. 2, the terminal device 120 can perform the operation of installing and executing the mobile application through the control unit 122. [0050] FIG.

Subsequently, in step S212, the server 110 registers the inserted copyright information in the registration unit 112. [ In this case, the server 110 confirms that the inserted copyright information is the copyright information for the normally purchased mobile app, using the user information of the terminal device transmitted together with the inserted copyright information, And the inserted copyright information can be registered in the registering unit 112 by matching.

Accordingly, the copyright information inserted in the normally purchased mobile app is registered in the registration unit 112 of the server 110. [ Hereinafter, for convenience of explanation, the copyright information that is inserted in the originally purchased original mobile app and normally registered in the registration unit 112 will be referred to as "first copyright information ".

On the other hand, when the terminal device 120 acquires the illegally copied original mobile app from the outside, steps S208 and S210 are performed in the same manner. However, in this case, the original mobile app is inserted with copyright information different from the first copyright information. Then, the server 110 determines whether the user information of the terminal device that is normally purchased (i.e., the user information of the terminal device registered in the registration unit 112) and the user information of the terminal device received through step S210 It is confirmed that they are different from each other, and the other copyright information transmitted together is not registered in the registration unit 112. [ Hereinafter, for convenience of explanation, the copyright information inserted in the illegally copied original mobile app will be referred to as "second copyright information ".

Next, with reference to FIG. 1 and FIG. 3, a method for blocking execution of a pirated mobile app according to an embodiment of the present invention will be described in detail.

In step S302, a request to execute a mobile app is generated in the terminal device 120. [ In this case, the copyright information is inserted in the mobile application in which the execution request is generated, the inserted copyright information may be first copyright information corresponding to the mobile app normally purchased, or the second copyright Information.

Thereafter, in step S304, the terminal device 120 compares the position of the terminal device 120 (hereinafter referred to as "current position") with the reference position at the time when the execution request is issued via the control section 122 do.

According to one embodiment of the present invention, the reference position is a position at which the mobile app is installed in the terminal device 120, a position at which the mobile app is most recently executed, (N is an integer equal to or greater than 2), and a detailed description thereof will be given later.

If the current position and the reference position are separated by a predetermined distance or more, a series of steps for execution control of the illegal copy mobile app described below are performed. Conversely, if the current location and the reference location are not more than a predetermined distance, a series of steps for controlling execution of the pirated mobile app are not performed. In other words, the server 110 and the terminal device 120 can determine whether the mobile app is normally purchased and control execution of the mobile app only when the current location and the reference location are separated by a predetermined distance or more And the like. According to an embodiment of the present invention, the predetermined distance may be determined based on a life pattern of a user who normally purchases the mobile app, and a detailed description thereof will be described later.

In detail, if it is determined that the current position and the reference position are separated by a predetermined distance or more, the terminal apparatus 120 transmits the copyright information inserted in the mobile app via the communication unit 122 to the server 110 ).

Then, in step S308, the server 110 confirms whether the inserted copyright information is registered in the registration unit 112. Then, In other words, the server 110 determines whether the inserted copyright information is first copyright information corresponding to the mobile app normally purchased, or second copyright information corresponding to the illegally copied mobile app.

Thereafter, in step S310, the server 110 transmits the execution control message of the mobile app to the terminal device 120 based on the determination result in step S308.

More specifically, if the inserted copyright information corresponds to the first copyright information (i.e., if it is determined that the mobile app is normally purchased), in step S310, the server 110 permits the execution of the mobile app (Hereinafter referred to as "first execution control message") to the terminal device 120. [ Conversely, if the inserted copyright information corresponds to the second copyright information (i.e., if the mobile app has been confirmed to be pirated), the server 110 in step S310 executes an execution for blocking execution of the mobile app (Hereinafter referred to as "second execution control message") to the terminal device 120. [

Finally, in step S312, the terminal device 120 controls the execution of the mobile app based on the execution control message received through the control unit 122. [

In detail, when the first execution control message is received, the terminal device 120 permits execution of the mobile application, and when the second execution control message is received, the terminal device 120 blocks execution of the mobile application.

In other words, the system 100 according to the embodiment of the present invention determines that the mobile app is normally purchased when the current position at the time when the execution event of the mobile app occurs is not more than a predetermined distance from the reference position And does not perform a series of steps for controlling execution of the illegally copied mobile app. When the current position at the time when the execution event of the mobile application is generated is separated from the reference position by a predetermined distance or more, the system 100 according to the embodiment of the present invention does not regard the corresponding mobile app as a normal purchase And performs a series of steps for controlling the execution of the illegally copied mobile app. The control procedure described above reflects the pattern of the user executing the mobile application.

More specifically, in general, the user of the terminal device 120 performs daily life within a certain radius, so that the mobile app is executed within a certain radius (life radius). Accordingly, if the normal purchaser of the mobile app executes the statistics of the locations where the mobile apps purchased by the mobile application are executed, the corresponding locations are within a predetermined range. Therefore, if the position at the time when the execution request of the mobile application is generated is not far away from the reference position, for example, the position at which the corresponding mobile app was most recently executed (that is, within the predetermined range) It is very likely that the app is executed by the normal purchaser. In this case, a series of procedures for judging whether or not the mobile app is illegally copied (steps S306 to S312) are unnecessary procedures. Accordingly, in this case, the system 100 according to the present invention does not perform the steps S306 to S312, thereby preventing unnecessary procedures from being performed. To this end, the predetermined distance may be statistically determined based on the life pattern of the normal purchaser.

However, it is common that illegal copy mobile apps are installed and executed by a third party having no relation with the above-mentioned normal purchaser, and their life radius is likely to be different from the life radius of the normal purchaser. Therefore, if the location at the time when the execution request of the mobile application is generated is far away from the reference position, for example, the position at which the corresponding mobile app was most recently executed (i.e., located outside the predetermined range) The system 100 in accordance with the present invention may perform a series of procedures for determining whether a mobile app is illegal or illegal (Steps S306 through S312).

As described above, the system 100 according to the present invention performs hijacking or sniffing because the server 110 and the terminal device 120 interlock with each other to determine whether the mobile app is illegally copied and to control execution of the mobile app. It is possible to judge whether the mobile app is illegally copied and to control execution of the mobile app safely.

In addition, the system 100 according to the present invention selectively performs determination and execution control of illegal copying of a mobile app based on a mobile app execution pattern of a normal purchaser, and can reduce unnecessary signaling and determination procedures .

In addition, embodiments of the present invention may be implemented in the form of program instructions that can be executed through various computer means and recorded on a computer readable medium. The computer-readable medium may include program instructions, data files, data structures, and the like, alone or in combination. The program instructions recorded on the medium may be those specially designed and constructed for the present invention or may be available to those skilled in the art of computer software. Examples of computer-readable media include magnetic media such as hard disks, floppy disks, and magnetic tape; optical media such as CD-ROMs and DVDs; magnetic media such as floppy disks; Examples of program instructions, such as magneto-optical and ROM, RAM, flash memory and the like, can be executed by a computer using an interpreter or the like, as well as machine code, Includes a high-level language code. The hardware devices described above may be configured to operate as one or more software modules to perform operations of one embodiment of the present invention, and vice versa.
