It should be understood, however, that the invention is not limited to the disclosed embodiments, but is capable of many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, To fully disclose the scope of the invention to those skilled in the art, and the invention is only defined by the scope of the claims. Like reference numerals refer to like elements throughout the specification.

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

1 is a diagram illustrating a network configuration of a risk detection system according to an embodiment of the present invention.

Referring to FIG. 1, a risk detection system 100 according to an embodiment of the present invention includes a protection target terminal 110, a service server 120, and a guardian terminal 130.

The person 110 to be protected refers to a terminal of a person to be protected such as a youth. The protection target terminal 110 may include a smart phone that supports a text message (SMS, MMS, etc.) and a mobile instant messenger (MMI) as well as an Internet browser.

The protection target terminal 110 determines whether a risk keyword is included in a message input from the outside, and if the risk keyword is included as a result of the determination, transmits the risk information including the risk keyword and the input message to the service To the server (120). A detailed description of the protection target terminal 110 will be described later with reference to FIG.

The service server 120 may receive and store the danger detection information from the protection target terminal 110 and provide the stored risk detection information to the caregiver terminal 130 as a notification service. Accordingly, the guardian can detect the danger of the person to be protected by checking the notification service provided through the guardian terminal 130. Here, for example, the guardian is a parent and the person to be protected may be a child. A detailed description of the service server 120 will be given later with reference to FIG.

The guardian terminal 130 displays a notification service provided from the service server 120 on the screen so that the guardian can detect the risk of the protected person. Also, the guardian terminal 130 may transmit an update request signal to the protection target terminal 130 through the service server 120 according to the input operation of the guardian. Accordingly, the person 130 to be protected can update the stored contents of the local risk keyword database (DB) storing the risk keyword and the local risk exception keyword DB storing the risk exception keyword. The guardian terminal 130 will be described in detail with reference to FIG.

FIG. 2 is a block diagram illustrating a detailed configuration of the protection target terminal 110 of FIG.

1 and 2, the protection target terminal 110 includes a server connection unit 210, a message collection unit 220, a message editing unit 230, a danger message determination unit 240, a local risk keyword DB 245 A local exception message determination unit 250, a local risk exception keyword DB 255, a risk message storage unit 260, a risk message transmission unit 270, and a local update unit 280.

The server connection unit 210 connects the protection target terminal 110 to the service server 120. At this time, the server connection unit 210 can be communicatively connected to the service server 120 through the protection target terminal connection unit (refer to 310 in FIG. 3) of the service server 120.

The server connection unit 210 performs session management so that communication between the protection target terminal 110 and the service server 120 is maintained until the danger detection system 100 according to an embodiment of the present invention is terminated can do.

The message collecting unit 220 collects a message input from the outside. That is, the message collecting unit 220 can collect SMS messages (MMS) inputted through the SMS program, or collect the messages of the mobile messenger inputted through the mobile messenger program. Alternatively, the message collecting unit 220 may collect comments of the SNS inputted through the mobile SNS program.

In other words, the message input from the outside may include at least one of a text message such as SMS, MMS, a message of the mobile messenger, and a comment of the SNS, At least one of which can be collected as a message input from the outside.

Here, the text message of the mobile messenger and the SNS of the text message such as the SMS message and the MMS message can be directly checked at the protection target terminal 110, Can not be confirmed immediately.

Accordingly, in an embodiment of the present invention, a TTS (Text To Sound) program 225 may be utilized for confirming the contents of text messages in the mobile messenger and comments in the SNS. That is, in the case of a message (comment) input through the mobile messenger or the SNS, the message collecting unit 220 collects the text in a state in which the input message is not converted into audio using the TTS program 225 can do.

Here, the TTS program 225 is a program for converting text into speech. The TTS program 225 is a system for notifying a user of various events (touch, menu selection, arrival of a message, etc.) generated by the smartphone by a sound for a visually impaired person using the smartphone, Is a program that is installed as a base.

The message editing unit 230 edits the message collected by the message collecting unit 220 and processes the message into a new character string. It is difficult for the adolescents, which are an example of the protected persons, to include dangerous keywords without editing the messages because the messages include various emoticons, symbols, spaces, and special characters in the messages. This is because if the message contains various emoticons, symbols, spaces, special characters, etc., it is difficult to grasp the exact meaning of the message.

Accordingly, in one embodiment of the present invention, the message editing unit 230 edits the message. For this, the message editing unit 230 removes emoticons, symbols, spaces, and special characters from the collected messages, and then edits the collected messages in a manner that all the syllables of individual countries are pasted, Can be processed.

For example, if the collected message is " The message editing unit 230 removes all symbols, spaces, and special characters such as "*", "!", And "~" from the collected message and then deletes only the syllables of the individual countries And edits the collected message in a manner of attaching it, so that it can be processed and output as a new character string "killer ".

The risk message determiner 240 refers to the local risk keyword database 245 to determine whether the string processed by the message editor 230 includes a danger keyword. Here, it is preferable that the local risk keyword DB 245 stores dangerous keywords that may threaten the safety of a person to be protected (youth) in a database and stores them in advance.

For example, it is assumed that there is a risk keyword such as " kill ", "kill ", etc. in the local risk keyword DB 245, and the character string output from the message editor 230 is" In this case, the risk message determiner 240 refers to the local risk keyword DB 245 and determines whether or not the risk word is included in the string "killer", which is the string output from the message editor 230 . Since the dangerous keyword "kill" is included in the "killer", the risk message determiner 240 determines that the risk word "kill" is a primary risk message.

The risk exception message determiner 250 refers to the local risk exception keyword DB 255 to determine whether the risk exception keyword is included in the string determined to contain the risk keyword. Accordingly, the risk message determiner 240 may determine whether the risk keyword is included in the string, based on whether or not the risk exception keyword is included.

Here, it is preferable that the local risk exception keyword DB (255) stores the risk exception keyword in a database in advance. At this time, the local risk exception keyword DB 255 may include at least one of syllable, letter, word, and sentence attached to the danger keyword before or after the risk keyword or both, and may be stored as the risk exception keyword.

For example, it is assumed that the risk keyword "die" includes a character other than the dangerous keyword such as "delicious die" or "die die", or both. In this case, since the risk word "die" is first found in the risk exception keyword DB 255, the local exception message determiner 250 determines that the danger exception keyword "eat delicious" and " It is checked again whether or not it is included in the new string.

At this time, if a dangerous exception keyword of "delicious die" or "eat dead" is found in the edited new string, the risk exception message determiner 250 regards the risk keyword determined as the primary risk message as a dangerous message . This is because even if a few "risky keywords" are found, the risky keywords can be homonyms that convey a variety of meanings. In other words, since the risk exception message determiner 250 may not be a dangerous message in the context of the entire message, it is a process necessary for more accurate risk message detection. In the case of the previous example, "dying" can be considered a danger message, but if it is "eat delicious", it can be considered not to be a danger message.

The risk message storage 260 stores the original message (collected message), the recipient ID (ID) of the character string (for example, (Name, nickname, phone number, etc.), a receiving channel (e.g., SMS, KakaoTalk, etc. as one of various paths), a receiving time And the danger detection information including the dangerous keyword (including the category) included in the character string.

The risk message transmitting unit 270 transmits the risk detection information to the service server 120 and stores the risk information in the risk message DB (see 320 in FIG. 3) of the service server 120. That is, the risk message transmitting unit 270 may transmit the danger detection information to the service server 120 through the periodical connection of the server connection unit 210. [

The protector can access the service server 120 through the caregiver terminal 130 and check the risk detection information stored in the risk message DB of the service server 120. [ The guardian terminal 130 may include a smart phone, a mobile phone, a tablet PC, a PC, and the like.

The local update unit 280 may update the local risk keyword DB 245 and the local risk exception keyword DB 255 according to an update operation of the parent terminal 130.

Specifically, the guardian terminal 130 may transmit an update request signal for the risk keyword and the risk exception keyword to the protection target terminal 110 according to the input operation of the guardian. At this time, the guardian directly inputs the risk keyword and the risk exception keyword, and transmits the risk keyword and the risk exception keyword together with the update request signal to the protection target terminal 110. Accordingly, the local update unit 280 The risk can be updated by storing the risk keyword and the risk exception keyword in the local risk keyword DB 245 and the local risk exception keyword DB 255. [

In other words, the guardian can directly confirm the keyword stored in the local risk keyword DB 245 and the local risk exception keyword DB 255, and further modify or delete the keyword directly or add a new keyword to the corresponding DB You can register. At this time, the guardian can update through the service server 120, directly access the protection target terminal 110, and update the protection target terminal 110 directly.

Meanwhile, the server connection unit 210 periodically tries to access the service server 120. The reason for attempting connection is to check whether the first program, the risk keyword, and the risk exception keyword are updated. Second, it is checked whether the risk detection system installed in the protection target terminal 110 is operating properly, 120).

In the second case, the server connection unit 210 periodically connects to the service server 120 and records in the service server 120 that the connection is successful. If the server is not connected to the server according to a predetermined period (for example, one week), the risk detection system of the protection target terminal is regarded as not functioning properly, and a notification message is sent to the guardian in this regard. Through this, the system helps to detect the risk of the person being protected (teen) normally and continuously.

3 is a block diagram illustrating a detailed configuration of the service server 120 of FIG.

1 and 3, the service server 120 includes a protection target terminal connection unit 310, a risk message DB 320, a guardian terminal connection unit 330, an update unit 340, a risk keyword DB 350, A risk exception keyword DB 360, and a non-response alarm unit 370. [

The protection target user terminal connection unit 310 connects the service server 120 to the protection target terminal 110. To this end, the protection target terminal connection unit 310 performs a session connection with the server connection unit (see 210 in FIG. 2) of the protection target terminal 110. When the session connection is established, the protection target terminal connection unit 310 maintains the session connection until the connection between the service server 120 and the protection target terminal 110 is terminated.

The risk message DB 320 stores the danger detection information transmitted from the protection target terminal 110 in a database. That is, the risk message DB 320 may receive and store the danger detection information from the danger message transmission unit 270 of the protection target terminal 110.

The parent terminal connection unit 330 connects the service server 120 to the parent terminal 130. To this end, the parent terminal connection unit 330 performs a session connection with the server connection unit (refer to 410 in FIG. 4) of the parent terminal 110. When the session connection is established, the parent terminal connection unit 330 maintains session connection until the connection between the service server 120 and the parent terminal 130 is terminated.

The guardian terminal connection unit 330 can provide the danger information to the guardian terminal 130 as a notification service by referring to the risk message DB 320 while the session connection is maintained. Accordingly, the guardian can preliminarily detect the risk (danger message) of the protected subject (teen) protected by himself / herself by confirming the contents of the danger detection information provided as a notification service to the guardian terminal 130.

The update unit 340 updates the risk keyword DB 350 and the risk exception keyword DB 360 in conjunction with the local update unit of the service server 120 (see 280 in FIG. 2) The local risk keyword DB 245 of the server 120 and the local risk exception keyword DB 255 may be synchronized.

The risk keyword DB 350 stores a danger keyword in a database and can be synchronized with the local risk keyword DB 245 of the service server 120 through the update.

The risk exception keyword DB 360 stores the risk exception keyword in a database and can be synchronized with the local risk exception keyword DB 255 of the service server 120 through the update.

The unacknowledged alarm unit 370 periodically analyzes the data communication state between the protector terminal 130 and the protection target terminal 110 and periodically analyzes the data communication state between the protector terminal 130 and the protection target terminal 110, An unacknowledged alarm message can be transmitted.

That is, the unacknowledged alarm unit 370 periodically analyzes the data communication state between the protector terminal 130 and the protection target terminal 110 and determines that the update has been performed when the data communication is performed, If the response message is not transmitted but data communication is not performed, it is determined that the update has not been executed and the non-response alarm message can be transmitted.

FIG. 4 is a block diagram illustrating a detailed configuration of the guardian terminal 130 of FIG.

1 and 4, the guardian terminal 130 may include a server connection unit 410, an update unit 420, and a non-response alarm confirmation unit 430.

The server connection unit 410 connects the caregiver terminal 130 to the service server 120. To this end, the server connection unit 410 performs a session connection with a parent terminal connection unit (refer to 330 in FIG. 3) of the service server 120. When the session connection is established, the server connection unit 410 maintains session connection until the connection between the guardian terminal 130 and the service server 120 is terminated.

3) or the local update unit (see "280" in Fig. 2) of the protection target terminal 110, An update request signal regarding the risk exception keyword can be transmitted. At this time, the update unit 420 may include the contents to be updated (the risk keyword and the risk exception keyword) in the update request signal.

In response to the update request signal, the protection target terminal 110 may modify or delete the contents stored in the local risk keyword DB 245 and the local risk exception keyword DB 255, or may add and register new contents .

The unacknowledged alarm checking unit 430 may receive the unacknowledged alarm message related to the non-execution of the update from the service server 120 and display the unacknowledged alarm message on the screen of the supervisor terminal 130. [ Accordingly, the guardian can check whether or not the update has been properly performed through the non-response alarm message displayed on the screen of the parent terminal 130.

5 is a diagram illustrating a process for detecting a risk message according to an embodiment of the present invention.

5, when a mobile messenger message "Look at PC desktop" arrives, the message is transmitted to the message collecting unit 220 via the TTS program 225, and the message editing unit 230 extracts, , Special characters, symbols except for Korean / English characters, such as a new string is created only.

The new string is organized as "look at the PC desktop." At this time, the risk message determiner 240 first compares all the risk keywords to find out whether the message is a dangerous message. In the local risk keyword DB 245, there is a risk keyword of "Ciba" (another expression of the word Cipher) and the danger message determiner 240 classifies the collected message into a danger message.

Thereafter, the risk exception message determiner 250 checks whether there is a risk exception keyword including a risk keyword "Ceba " identified as a risk keyword. The risk exception keyword DB 255 includes a risk exception keyword called " Ciba tang "(meaning PC desktop) including" Ciba ". In this way, the risk exception keyword found in the risk exception keyword DB (255) is again found to exist in the new string. The new string is identified by the string "Cibata". Therefore, the message "look at PC desktop" is not a critical message and ends the process. This process can increase the accuracy of risk message detection.

This is because, even if a number of "dangerous keywords" are found, the dangerous keywords may not be dangerous messages if they are identified in the context of the entire message, since they may be homonyms that convey various meanings. Therefore, this process is necessary for more accurate risk message detection. In the above case, it can be regarded as a dangerous message if only "Cuba" is seen, but it is not considered a dangerous message because it can not be called a "dangerous message".

6 is a block diagram illustrating a risk detection system according to another embodiment of the present invention.

6, the protection target terminal 610 includes a server connection unit 611, a search term collection unit 612, a TTS program 613, a search term editing unit 614, a dangerous keyword determination unit 615, A risk word query storage unit 616, a risk exception query determination unit 617, a local risk exception keyword DB 618, a risk query storage unit 619, a dangerous query transmission unit 620, and a local update unit 621 .

The service server 630 includes a protection target terminal connection unit 631, a risk term DB 632, a guardian terminal connection unit 633, an updating unit 634, a risk keyword DB 635, a risk exception keyword DB 636, And may include a non-response alarm unit 637.

The guardian terminal 650 may include a server connection unit 651, an update unit 652, and a non-response alarm confirmation unit 653. [

In the risk detection system of FIG. 6, the process of detecting a dangerous query is basically the same as or similar to the function of detecting a dangerous message. However, the only difference is that the search target terminal 610 collects a search word in the built-in internet browser of the youth smart phone and the internet browser for the user installation, for example. Accordingly, only the components that differ from the risk detection system of FIG. 1, in particular, the components different from the protection target terminal 110 of FIG. 1, will be described in this embodiment.

The search term collection unit 612 may collect search terms input through the Internet built-in browser or the Internet browser application. At this time, the search word collection unit 612 can collect the input search word as text without converting the input search word into an audio through the TTS program 613 in the case of a search word input through the Internet browser application.

The search word editing unit 614 edits a search word collected by the search word collecting unit 612 and processes the search word into a new character string. The search word editing unit 614 removes all the emoticons, symbols, spaces, and special characters from the collected search words, and then edits the searched words in the way that all the syllables of the individual countries are pasted, have.

The risk word determination unit 615 refers to the local risk keyword DB 616 to determine whether the string processed by the query word editing unit 614 includes a risk keyword.

The risk exception query determining unit 617 refers to the local risk exception keyword DB 618 to determine whether the risk exception keyword is included in the string determined to contain the risk keyword. Accordingly, the risk word determination unit 615 may determine whether the risk keyword is included in the string, based on whether or not the risk exception keyword is included.

If the risk word determination unit 615 determines that the risk keyword is included in the risk word storage unit 619, the risk word storage unit 619 stores the original keyword (collected query), the searcher ID (ID) (ID) for identifying a person such as a telephone number by the ID of the youth), a search channel (for example, one of various paths such as Naver and the next), a search time, and a risk keyword Store information.

The risk word transmission unit 620 transmits the risk detection information to the service server 120 and stores the risk detection information in the risk word DB 632 of the service server 120.

7 is a flowchart illustrating a method of detecting a risk according to an embodiment of the present invention. In the present embodiment, the danger detection method may be performed by a risk detection system mounted on the protection target terminal 110 of FIG.

Referring to FIGS. 1, 2 and 7, in step 710, the local risk keyword DB 245 of the risk detection system stores a dangerous keyword that may threaten the safety of the protected object.

Next, in step 720, the message collection unit 220 of the risk detection system collects a message input from the outside.

Next, in step 730, the message editing unit 230 of the risk detection system edits the collected message and processes it into a new character string.

Next, in step 740, the risk message determination unit 240 of the risk detection system refers to the local risk keyword DB 245 to determine whether the processed string includes a risk keyword.

If it is determined in step 760 that the risk keyword is included (step 750, Yes), the risk message storage unit 260 of the risk detection system stores the message, the recipient ID, the sender ID, A reception channel, a reception time, and a danger keyword included in the character string.

Next, in step 770, the risk message transmission unit 270 of the risk detection system transmits the risk detection information to the service server 120 and transmits a risk message DB (" Quot; 320 ").

On the other hand, if it is determined that the dangerous keyword is not included ("No" direction of 750), the present embodiment ends.

8 is a flowchart illustrating a method of detecting a risk according to another embodiment of the present invention. In the present embodiment, the danger detection method may be performed by a risk detection system mounted on the protection target terminal 110 of FIG.

In step 810, the risk detection system stores, in the local risk keyword DB 245 and the local risk exception keyword DB 255, a risk keyword and a risk exception keyword that can threaten the safety of the protected object, respectively.

Next, in step 820, the message collecting unit 220 of the risk detection system collects a message input from the outside.

Next, in step 830, the message editing unit 230 of the risk detection system edits the collected message and processes it into a new character string.

Next, in step 840, the risk message determination unit 240 of the risk detection system refers to the local risk keyword DB 245 to determine whether the processed character string includes a danger keyword.

If the risk keyword is included (Yes in step 850), the risk exception message determination unit 250 of the risk detection system refers to the local risk exception keyword DB 255 in step 860 , It is determined whether or not the risk exception keyword is included in the string determined to contain the risk keyword.

As a result of the determination, if the risk exception keyword is not included (No in 870), the risk message determination unit 240 of the risk detection system determines that the risk word is included in the character string, The danger message storage unit 260 of the risk detection system considers a dangerous keyword included in the character string as a source of the character string, a receiver ID, a sender ID, a reception channel, a reception time, And stores the danger detection information that it contains.

Next, in step 890, the risk message transmission unit 270 of the risk detection system transmits the risk detection information to the service server 120 and transmits a risk message DB (" Quot; 320 ").
