In addition, when a part is said to "include" a certain component, which means that it may further include other components, except to exclude other components unless otherwise stated.

Before describing an embodiment of the present invention, the meanings of the terms used below are first defined.

"Danger" means the nature of a publication that is unsuitable for disclosure to minors or other protected persons, such as harmful, violent, intimidating, obscene, banned, or adult persons. Therefore, "danger word" means a word having this inappropriate character, and "danger message" means a message containing a dangerous word. Therefore, a message containing abusive or violent or intimidating words received by the guardian may be called a dangerous message.

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

Referring to FIG. 1, the system for providing the assured security service according to an embodiment of the present invention includes a risk message monitoring apparatus 100 and a guardian terminal 200. The dangerous message monitoring apparatus 100 may be configured of the terminal to be protected 110 and the server 120.

The protected terminal 110 is a terminal possessed by the protected party, and may be a text message (for example, an SMS or MMS message) or an instant message (for example, a message of a messenger application), an SNS message, or the like from a third party server (not shown). You can receive e-mails. Subsequently, when it is detected that a dangerous word such as “XXX, get money” is included in the received message, the protected terminal 110 transmits a dangerous message including the dangerous word to the server 120.

The server 120 receives the risk message and transmits it to the guardian terminal 200. The server 120 may search for identification information of the guardian terminal 200 registered in the server 120 in correspondence with the guardian terminal 110 by referring to the information of the guardian terminal 110 that has sent the dangerous message. have. Subsequently, the server 120 may transmit a risk message to the retrieved guardian terminal 200.

The guardian terminal 200 receives the risk message from the server 120 and displays the risk message, thereby providing the guardian with the risk message received by the guardian. Through this, the guardian who has the guardian terminal 200 can check whether a dangerous state of his / her guardian is exposed. For example, knowing that your child has received a threatening message, such as “XXX, Bring money,” so that your child can be aware of the dangers he or she is facing, even if he or she does not speak to you. Opportunities can be provided to take appropriate measures in advance so as not to flow into more serious situations.

In this case, the guardian terminal 110 and the guardian terminal 200 may be installed by the guardian and the guardian assured application, respectively, the risk message monitoring and notification operation as described above by the operation of the assured assured application.

In this case, the network (N) for relaying communication between the guardian terminal 110, the server 120, and the guardian terminal 200 may include a local area network (LAN), a wide area network (WAN), and a value-added communication network. (Value Added Network; VAN), Personal Area Area Network (PAN), mobile radio communication network, Wireless Broadband Internet (Wibro), Mobile WiMAX, High Speed Downlink Packet Access (HSDPA) or satellite network It can be implemented with all kinds of wired / wireless networks.

In addition, the guardian terminal 110 and the guardian terminal 200 may be implemented as a computer, a portable terminal, or a television that can be connected to the server 120 at a remote location through the network N, or can be connected to other terminals and the server 120. have. Here, the computer includes, for example, a laptop, desktop, laptop, etc., which is equipped with a web browser, and the portable terminal is, for example, a wireless communication device that ensures portability and mobility. , Personal Communication System (PCS), Personal Digital Cellular (PDC), Personal Handyphone System (PHS), Personal Digital Assistant (PDA), Global System for Mobile communications (GSM), International Mobile Telecommunication (IMT) -2000, Code CDMA Division Multiple Access (2000), all types of handhelds such as W-Code Division Multiple Access (W-CDMA), Wireless Broadband Internet (Wibro), Smart Phones, and Mobile Worldwide Interoperability for Microwave Access (WiMAX). It may include a (Handheld) based wireless communication device. In addition, the television may include an Internet Protocol Television (IPTV), an Internet Television (Internet Television), a terrestrial TV, a cable TV, or the like.

Hereinafter, with reference to FIG. 2, the internal configuration of the dangerous message monitoring device 100 will be described in detail. The dangerous message monitoring device 100 includes a protected terminal 110 and a server 120, and the components described with reference to FIG. 2 may be selectively employed in the protected terminal 110 or the server 120. .

The access right setting unit 101 sets an access right for the supervised monitoring application so that the supervised monitoring application installed in the supervised terminal 110 can monitor the message received by the supervised terminal 110. The access right may mean an access right for the application state information storage area of the protected terminal 110.

The application state information storage area is an area included in the operating system of the to-be-protected terminal 110 or configured independently of the operating system, and temporarily or permanently stores texts, messages, files, etc. received by various applications arranged under the operating system. Area. The information stored in the application state information storage area may be information that can also be seen by the general user by requesting the general user of the terminal to view the stored information. For example, the information stored in the application status information storage area may be information listed in an application status window that appears according to a user input dragged from the top to the bottom of the smart device. Generally, about an application registered in the application status window. If there is an update status, the push notification may be configured to be sent to the terminal, and the user may check the update status information by reading the application status window. For example, a chat message of A received by the chat application or The SNS message of B received by the SNS application is also stored in the application state information storage area and may be included in the monitored target of the assured user.

The access right setting may be automatically performed at the same time as the installation of the guardian monitoring application, or may be manually performed according to the input of the guardian or guardian. For example, when the guardian inputs the access right setting button of the guardian monitoring application, the access right setting unit 101 may grant the guardian monitoring application access to the application state information storage area of the guardian terminal 110. .

The message receiving unit 102 receives a message from the outside (ie, an external server or an external terminal). The message received by the message receiver 102 may be any one of a text message (eg, SMS, MMS, etc.), an instant message (eg, a chat message of a chat application), an SNS message, and an email. For example, the message receiver 102 may receive a message of a chat application such as KakaoTalk, Line, TickTalk, Nate-On, etc., and a short message of a message application installed in the protected terminal 110.

The message recognition unit 103 recognizes the content of the received message. In detail, the text message may be recognized by referring to the message storage area of the dangerous message monitoring device 100. In addition, in the case of an instant message, it can be recognized by referring to the application state information storage area. In general, in the terminal which is currently spreading, access to the message storage area for storing text messages is set to allow any application installed in the terminal. (For example, among household account books, there is an application that automatically calculates the accounting history by referring to the card transaction text message.) However, individual applications downloaded from the application market store (for example, a chat such as KakaoTalk or Line) In the case of a message received from an application), if the application does not gain access to the server (not shown) of each application, the individual application is set to be inaccessible to the received message. However, in order to gain access to the server of each application, it is difficult to enter into an alliance with the service provider. However, one embodiment of the present invention can recognize instant messages other than text messages by granting access rights to the application state information storage area without obtaining access rights to each chat application server.

The dangerous message determination unit 104 determines whether the received message is a dangerous message. The dangerous message determination unit 104 compares the received message with the dangerous word list, and determines the received message as a dangerous message when the dangerous message is included in the received message. For example, when the word “get money” is included in the risk word list and a message including the word is received, the risk message determination unit 104 may determine that the received message is a risk message.

The dangerous word storage unit 105 stores the above-mentioned dangerous word list. The risk word list is a set of risk words that are classified into a plurality of categories. The plurality of categories may include, for example, ① violence / threatening ② pornography / adults ③ harmful / profanity ④ suicide / deviation ⑤ other harmful words. The risk word storage unit 105 may update and store the risk word list regularly or irregularly. For example, the dangerous word storage unit 105 may update and store the list of dangerous words input by the service manager, or update and store the words recognized as dangerous words among the dangerous messages received by the protected terminal 110. .

The sender information extracting unit 106 extracts the sender information of the dangerous message from the calling identification information of the dangerous message. Specifically, the sender information extracting unit 106 may grasp the contact information (for example, a phone number, an e-mail address, an SNS account address, and a chat application ID) of the dangerous message through the address of the dangerous message. Subsequently, the caller information extracting unit 106 determines whether the caller's contact information is registered in the danger message monitoring apparatus 100, and if registered, the caller information extraction unit 106 stores the caller's name (or nickname) stored in correspondence with the registered caller's contact information. You can find out the name of the sender by searching. On the other hand, when the received message is an instant message and the contact information of the instant message is stored in the application status information storage area, the sender information extracting unit 106 refers to the information of the contact partner, thereby calling the sender's name or contact information. Can be identified.

The risk information transmitter 107 transmits the risk message and the sender's information to the protected terminal 110. The sender's information to be sent includes the sender's name or contact information. Here, the name or contact information of the sender corresponds to personal information, and when transmitted without filtering, there may be a risk of indiscriminate exposure of personal information. Therefore, the risk information transmitter 107 may mask a part of the caller's name or a part of the caller's contact information and transmit the masking process to the guardian terminal 200. For example, at least one “*” may be inserted into a syllable in the center of the caller's name or in the center area of the caller's contact.

If there is a risk message sent by the sender of the dangerous message from which the information is extracted from the sender, the sender adds information extractor 108 may extract and provide information on the other protected. Caller add information extraction unit 108 may be a configuration that is included in the server 120 of the dangerous message monitoring device 100 preferably. The sender abuse information extraction unit 108 transmits the dangerous message sender information (name or contact information) and the dangerous message when the risk message is transmitted from the guardian terminal 110 to the guardian terminal 200. ) Information can be stored correspondingly. Accordingly, the sender abuse information extraction unit 108 may store information of several victims (ie, users of the protected terminal 110) with respect to one perpetrator (that is, dangerous message sender). Therefore, the caller abuse information extraction unit 108 may extract information of other protected persons associated with the caller through the caller information. For example, it can be seen that there are B, C, and D protectees to whom the sender A sends a danger message. The sender abuse information extraction unit 108 may transmit the extracted information of the other protected persons to the guardian terminal 200. Here, some of the names or contacts of other guardians may be masked and transmitted, or may be displayed without being masked by the guardian terminal 200 after being transmitted to the guardian terminal 200 without editing.

Referring to FIG. 3, the guardian terminal 200 corresponding to the risk message monitoring apparatus 100 may include a risk information receiver 201 and a risk information provider 202.

The risk information receiving unit 201 receives the risk information transmitted by the risk message monitoring apparatus 100. That is, the risk information receiving unit 201 may receive the risk message and the sender information of the risk message received from the protected terminal 110.

The risk information provider 202 provides the received risk message and the sender information so that the guardian can see it. Here, the risk information providing unit 202 may provide the contents and statistics of risk information for the protectee. Specifically, the risk information providing unit 202 may include the total number of dangerous messages received by the guardian, the information of the sender (for example, the name of the sender, the contact number, the total number of dangerous messages transmitted by the sender, and the sender of the message). A recent dangerous message was received by the custodian, the information of the dangerous message (e.g., the type of application that received the dangerous message, the time of receipt of the dangerous message, the category of the dangerous word contained in the dangerous message, and the content of the dangerous message). Can be provided.

Referring to FIG. 5, a risk information providing interface displayed on the guardian terminal 200 is illustrated. In the R1 region of the risk information providing interface, the total number of dangerous messages received by the guardian terminal 200 is displayed. Here, the total number of dangerous messages and the number of recently received dangerous messages may be displayed together. In addition, the sender's information is displayed in the R2 area. Here, the sender's name and contact information are masked and provided in some areas, and the total number of received messages for each sender is displayed together. In this case, the risk information providing unit 202 displays the name or contact information of the caller who has been masked from the dangerous message monitoring device 100 or receives the original caller's name or contact information from the danger message device, and then masks it. It can also be displayed. In addition, the R3 area provides information indicating that the dangerous message is a text message such as SMS or MMS or an instant message such as KakaoTalk message, and the received date of the dangerous message and the category of the dangerous word included in the dangerous message are also included. It is provided.

Hereinafter, referring to FIG. 4, the system for providing the assured security service according to an embodiment of the present invention further includes a risk providing unit 301, a risk word purpose determining unit 302, and a caller association determining unit 303. It may also include. The risk providing unit 301 and the risk word purpose determining unit 302 may be implemented to be included in either the risk message monitoring apparatus 100 or the guardian terminal 200.

The risk provider 301 may determine the risk of the sender of the risk message and provide the guardian. The degree of risk represents the degree of danger to the actions of the sender of the danger message to the custodian, and can be calculated by numerical value or color. For example, the risk rating can be expressed as 0 to 10, the value of any of these figures, or the risk rating as yellow, green, or red, and the color of any of these colors. have. The risk may be determined according to at least one of the total number of risk messages sent by the sender, the number of risk words included in the risk message, and the risk level of the risk words included in the risk message. The risk level is a level indicating the seriousness of the dangerous situation of the word, and the words of the risk word list stored in the risk message monitoring device 100 have different risk levels according to at least one of violent, threatening, and harmful. May be specified. For example, words such as “go off”, “dull”, “torai”, “sad”, etc. can be terms that can often be mentioned without the purpose of harm, so they are set to have a low risk rating, “bring money”, “ Words such as "Bamboo" and "Would Tear" can be set to have a high risk rating.

When the risk provider 301 is implemented in the server 120, the risk may be determined based on a risk message sent by one sender to several guardians, and the risk provider 301 is implemented in the guardian terminal 200. If so, the risk may be determined based on the risk message sent by one sender to one protector.

By providing this risk to the guardian, the guardian can predict in advance how dangerous the sender of the risk message is. For example, if the risk is low, the guardian thinks of joking or using a little excessive language between friends, or if the risk is high, the guardian can immediately recognize that the sender's school violence is serious.

The risk word purpose determination unit 302 determines whether the risk word is a word having a characteristic such as violence or intimidation or a joke or a friendliness display, and filters the latter if the latter is a risk message. It may not provide or inform the guardian that the message is of low risk. In general, adolescents use swear words or slang words habitually as a meaningless or as a friendly sign. In this case, if the guardian recognizes the danger message and informs the guardian, the guardian receives an unnecessary message, and the guardian is invaded with the privacy of the unnecessary area. Although the risk providing unit 301 described above provides some functions for improving such a problem, it may not be able to completely filter unnecessary risk messages.

Accordingly, in order to eliminate such unnecessary points, the risk word purpose determination unit 302 may determine the purpose of the risk word through pattern analysis between the received message and the message input by the protected person. For example, after the dangerous message is received by the custodian terminal 110, the custodian inputs a message including the dangerous word within a certain time period, or includes a positive word such as “ㅋㅋ”, “ㅎㅎ”, or “laugh”. In the case of inputting the message, the danger message received by the guardian can be judged as a message of joke or friendliness display. Alternatively, if a message containing a dangerous word having a high risk level is continuously received more than a predetermined number of times, it may be determined that the message is a dangerous message for violence or threatening purposes.

When the risk word purpose determination unit 302 is implemented in the risk message monitoring apparatus 100, a message of a joke or a friendliness display may not be transmitted to the guardian terminal 200.
