Description

A METHOD AND A SYSTEM FOR FILTERING SPAM SHORT MESSAGES}

The present invention relates to a method and a system for filtering short text messages, and more particularly, to create an opt-in / opt-out registration list based on a simple operation of a user for a short text message that a user does not want. The present invention relates to a method for filtering short text messages and a system for filtering and transmitting short text messages to the user based on the reception allow / deny registration list.

In general, an electronic message (collectively referred to as an e-mail or a short message) that a sender sends to a user who has nothing to do with it is called a spam message.

Many of today's mobile service providers are experiencing significant workloads due to these spam short messages. In addition, recently, a survey result of the Ministry of Information and Communication has revealed that the user's damage caused by the indiscriminate spam short message is so great that most users of the mobile communication terminal have received such a spam short message.

In order to prevent such spam messages, the SMS spam filtering method according to the prior art uses the Opt-in method in the case of spam sending using a short message service (SMS) application service provider (ASP). In the case of full application, filtering of most spam messages can be performed, but this type of filtering can lead to a downturn in the short message service (SMS) market and provide portal services by opt-in SMS filtering. The resistance of the companies is not small and there is a problem that the definition of spam messages may be obstructed to activate the service using a short message. In addition, in the case of using the short message sender, since the transmission of the short text message is performed in a manner similar to the transmission of the short text message between the general users, the above-described filtering method using the Opt-in method is not possible, Although it is possible to apply the opt-out filtering method, the process for creating the opt-out filtering list is inconvenient, and it can cause damage to the user after the message containing the unhealthy contents is exposed to the user. There is a problem.

As shown in FIG. 1, although Opt-out type registration can be registered through a message manager, when a user receives a short message to a mobile communication terminal through the wireless Internet, The text message should be read first, and after reading the short text message, the user can re-connect to a predetermined filtering system through the wireless Internet and go through several complicated steps to set the filtering of the short text message. In other words, the problem that the spam registration process for the spam short message is complicated is a big problem, and furthermore, the user memorizes the sender number to be filtered in order to set the filtering, and then manually inputs it into the filtering system. There was discomfort.

As shown in FIG. 2, although Opt-out can be registered through the message manager provided by the website, when the user receives a short message to the mobile terminal through the wireless Internet, the user The short text message should be read first, and after reading the short text message, a message blocking function provided by the website will be available only after accessing a website of a mobile communication company that provides a mobile communication service through a wired or wireless Internet network using a computer. I was able to register settings. This method of filtering short text messages has a problem in that the registration procedure is very complicated from the user's point of view, as shown in FIG. In addition, as described above, the user is implemented so that the user can take action on the rejection only after receiving the short message with the unhealthy contents, so that only the filtering by the calling party number is possible and the spam short message with the callback URL is available. There was a problem that the registration can not be registered for.

There is an urgent need for a method that can overcome the problems of the conventional spam short message blocking service and provide a more convenient spam short message blocking service to a mobile communication user to fit a new mobile communication environment.

The method and system for filtering short text messages according to the present invention have been devised to solve the above-described problems, and provide a function of allowing / rejecting opt-in / opt-out for a predetermined short text message. In order to be able to receive a short text message, and to facilitate the convenience of users of the short text message.

In addition, it is an object of the present invention to provide a method and system for filtering short text messages so that a healthy communication culture can be established among users of a mobile communication terminal.

In addition, the method and system for filtering short text messages according to the present invention enables the user to set filtering on the short text message even before the user reads the short text message, thereby preventing users such as minors from harmful environments such as obscene short text messages. Its purpose is to protect.

Short message used throughout the present specification is used for convenience of description, and technically a concept including a simple message service (SMS) or a multimedia message service (MMS) in a narrow sense. If the message includes a predetermined caller information (caller number or caller URL, etc.), it is defined as being included in the short message used in the present specification.

Hereinafter, a method and system for filtering a short message according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

3 is a flowchart illustrating a method of filtering a short message according to the present invention. Hereinafter, referring to FIG. 3, the processes performed for each step in the short message filtering method according to the present invention will be described in detail.

First, in step S310, a single-character message filtering database that records a predetermined reception allow / deny registration list set by the user is maintained. According to the present invention, the reception allow / deny registration list is a list to which the Opt-in / Opt-out filtering is applied simultaneously. As will be appreciated by those skilled in the art, the Opt-in method refers to a positive method of transmitting only a short message satisfying a predetermined filtering condition input by the user to the user, and the Opt-out method refers to a user input. A negative method that blocks only short messages that satisfy a predetermined filtering condition.

4 is a diagram illustrating an example of a reception allow / deny registration list according to the present invention.

The short message filtering database records a list of allow / deny registrations for each user. Referring to FIG. 4, the reception allow / deny registration list may include user information and caller information, and the user information may include a user name, a user identifier (ID), or a mobile communication terminal number of the user. The caller information may include a calling number and a calling universal resource locator (URL). The user identifier is a member identifier provided by the website only when a user accesses a website provided by a mobile carrier that subscribes to a mobile communication service and registers as a member. The user identifier is given to a user who does not register as a member. It may not be. Depending on the implementation, the user information may be transmitted from the member database of each mobile carrier.

Originally, URL is an abbreviation of 'Uniform Resource Locator' and means a format that can consistently express the address of a resource accessible from the Internet. The type of resource may vary depending on the Internet application protocol. These URLs consist of the name of the protocol needed to access the resource, the domain name to identify the particular computer on the Internet, and the pathname hierarchically indicating the location of the computer file, for example 'http: //www.wisegram .com / kor '.

In step S320 of FIG. 3, a short message service (SMS: Short Message Service, or MMS: Multimedia Message Service) including the caller information is received from the caller. The sender may be an individual user or a content provider that provides certain content.

In step S330, the reception allow / deny registration list corresponding to the caller information included in the short message is referred to by referring to the short message filtering database. The sender information corresponding to the sender information included in the short text message is read by searching the reception allow / deny registration list of the short text message filtering database.

In step S340, it is determined whether the caller information is included in the reception allowance / deny registration list according to the search result of step S330. When the caller information is included in the reception allowance registration list, the user is determined. Transmits the received short message to the mobile communication terminal of the terminal, and if the sender information is included in the unsubscribe registration list, stores the spam short message without transmitting the short text message to the user's mobile communication terminal. To the means. In this case, the short message recorded in the spam short message storing means may be implemented to be automatically deleted after a certain period of time, and the user may use the user terminal (personal portable) through a communication network such as a wired / wireless internet network or a mobile communication network. A terminal or a personal computer, etc.) to read or delete the spam short message stored in the spam short message storage means.

5 is a conceptual diagram illustrating a spam short message filtering service according to the present invention. As shown in FIG. 5, the short message message filtering system according to the present invention receives a short message sent from a sender, and receives a call corresponding to the sender information included in the short message by referring to the short text message filtering database. As a result of searching the allow / deny registration list, when it is determined that the caller information is registered in the allow registration list, the short message 540 is allowed to receive and is automatically transmitted to the mobile communication terminal of the user. If it is determined that the sender information is registered in the complaint registration list, the short message 540 is rejected and is automatically stored in the spam short message storage box 550.

In step S350 of FIG. 3, when the caller information is not included in the reception allow / deny registration list as a result of the search in step S330, the sender information of the short message is included in the mobile communication terminal of the user. It sends a short message acknowledgment request. An example of the confirmation request may be "A text message has been received from ***-####. Do you want to confirm? Please press the [Call] button for confirmation." The short message receipt request may include a call back URL or a call back number for access to the spam short message filtering system according to the present invention.

The method of performing step S350 will be described in detail with reference to FIG. 5 as follows. If the sender information of the short message is not included in the allow / deny registration list recorded in the short message filtering database according to a search result, that is, the sender information is not included in the allow / deny register list set by the user. In the case of an unregistered state that is not registered, the acknowledgment request message 510 for the short message is transmitted to the user's mobile communication terminal.

In step S360 of FIG. 3, the mobile terminal of the user receives a response request response of the short message to the short message receipt request. The reception request response of the short message is performed through a user's acknowledgment to the short message receipt confirmation request. Referring to the example described above, as shown in FIG. 5, the user receives the short message by pressing a call button of the mobile communication terminal with respect to the short message reception confirmation request displayed on the screen of the mobile communication terminal. The callback URL or the callback number of the short message filtering system according to the present invention included in the confirmation request can be connected to the short message filtering system.

In step S370, the short text message and the reception permission / deny setting registration message are transmitted to the user's mobile communication terminal in response to the user's reception request response. As shown in FIG. 5, in response to the reception request response of the user, the short message filtering system according to the present invention transmits a short text message and a reception permission / deny setting registration message 520 to the mobile communication terminal of the user. Will be sent.

In step S380, setting registration information corresponding to the reception permission / deny setting registration message is received from the user's mobile communication terminal. As shown in FIG. 5, the user confirms the short message and selects one of the allow and the unsubscribe through the short message and the allow / deny setting registration message 520, and inputs the selection input. Based on the request, the short message filtering system requests that the sender information included in the short message be set to be allowed or denied. That is, the short message filtering system receives the setting request information from the mobile communication terminal of the user. In addition, after checking the short message, the user may not select one of the reception permission and the rejection of the sender information of the short message. Therefore, the short message that the user does not select either the allow or the unsubscribe will be returned to step S350 again if a short message including the same sender information is received later, and the above-described procedure will be performed again. Can be.

In step S390, the received setting registration information is recorded in the short message filtering database. As shown in FIG. 5, a message for confirming that the short message is accepted or rejected is prepared by creating a reception allow / deny registration list related to the received setting registration information and storing it in the short message filtering database. 530 may be transmitted to a user's mobile communication terminal.

As another embodiment of the present invention, the short message filtering system according to the present invention does not immediately transmit a short message sent by a caller to a user who is a user, but transmits it to a mobile communication terminal of a parent of the user who is the user. After confirming the click, a function of registering the reception permit / deny registration list of the youth may also be provided. In order to provide such a function, the juvenile identification procedure may be implemented together.

As another embodiment of the present invention, FIG. 6 illustrates an example of a user interface for performing reception registration / deny setting registration through a user response to a short message receipt request.

Referring to FIG. 6, when a predetermined short message including sender information is received from a sender, the short message filtering system searches for a list of allow / deny registration lists recorded in a filtering database based on the sender information. If the caller information is not included in the reception allow / deny registration list according to a search result, an acknowledgment request message 610 for the short message is transmitted to the user's mobile communication terminal. Accordingly, when the user responds to the acknowledgment request message 610, the short message filtering system transmits the short message and the reception permission / deny setting registration message 620 to the mobile communication terminal of the user. Done. At this time, if the user transmits the setting registration information for registering the short message as a permission to receive, the short message filtering system records the received setting registration information in the short message filtering database and then the user. The reception permission confirmation message 630 is transmitted to the mobile communication terminal. In contrast, when the user transmits setting registration information for registering the short text message as a rejection, the short text message filtering system records the received setting registration information in the short text message filtering database and then the user. The transmission confirmation message 640 is transmitted to the mobile communication terminal. In addition, the user does not register any setting through the received short message and the allow / deny setting registration message 620, and selects spam management 650 to edit a preset allow / deny registration list. The procedure can be performed. In other words, you can delete the preset configuration properties or change the security settings between the safe and unsubscribe properties, or manage spam by selecting Spam Managed Box (660) from the Spam Management (650) menu. It may be implemented to select, view and delete the spam short message stored at 660. In this case, by using the user's mobile communication terminal to be connected to the short message filtering system through a mobile communication network, it may be implemented to perform a user authentication for the user using the number of the mobile communication terminal, For user authentication, the user authentication method disclosed in Korean Patent Laid-Open Publication No. 10-2003-7278 (name of the invention: instant login user authentication and payment method using a heterogeneous communication network and its system) can be used.
