Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a smart phone,

The present invention relates to a method for blocking a spam texting message that a smartphone user does not want, and more particularly, to a method for blocking a spam texting message that a smartphone user can not block, When the modified spam texting message is received, it is corrected using words and phrases according to Korean spelling by using the character recognition technology, and the special characters, symbols, and numeric alphabets that can not form a syllable are removed, do. Then, when the syllable is compared with the spam word and the spam phrase registered in the spam DB, or the syllable is compared with the word or phrase registered as spam, And not to receive the message.

In general, when a mobile user sends an unwanted text message to an unspecified number of people, it is called a spam character and has been used since 2002 as a method of advertising marketing. Especially, illegal loan, game, gambling, and adult text messages continued to increase due to lack of special enforcement by 2009, but since 2010, they have been cracking down on the four major spam reduction policies of the Korea Information Security Agency It is still a reality that is not eradicated.

Especially recently, it is not the purpose of simply sending a text message to lure a recipient into a lending or game gambling, but a smile character with a URL link address that tricks smartphone users into installing illegal software on their smartphones. Smartphone users are unaware of this, and users are directly affected by money.

In order to block spam, your smartphone is provided with a function called spam blocking by default, and you can register and block spam numbers and spam phrases. However, even if you register spam numbers and spam words or phrases, If it changes a bit, it is not blocked by spam. Especially, it is impossible to block spam characters that are visually recognizable but not spelling by mixing special characters, alphabets, symbols, numbers, etc. rather than characters using only normal Korean words. In order to prevent harmful users from being harmed by such spam characters, spam prevention technologies that can respond more intelligently are needed instead of a formal method of blocking simple number blocking phrases.

In the present invention, a smart-phone user installs a character recognition spam-blocking system on a smart phone without receiving an unwanted spam message every time and deletes it, or registers it in a spam number or continuously registers a spam phrase. The present invention provides a method for blocking similar spam text messages transformed by registration.

A method for blocking reception of a spam message by a smartphone user includes the steps of registering a message in a mobile phone memory by a character recognition agent before storing the message in a message box when the smart phone receives a text message transmitted from the base station, Extracting characters such as special characters, alphabets, symbols, and numbers from the message registered in the memory after the step; comparing the extracted special characters, alphabetic characters, symbols, and numbers with the character recognition DB to obtain a normal Korean consonant A step of reconstructing a word and a phrase according to a spelling and a step of combining a secondary message by removing the remaining special characters, alphabetic characters, symbols, and numbers that are left unconverted after the step, Processing the same words and phrases as spam as compared with the DB, If there is no word or phrase, the first syllable of the word or phrase registered in the spam database is sequentially compared with the content of the secondary message. If the first syllable exists, the second syllable and the third syllable are sequentially compared A step of processing the text message as spam if all words, phrases and syllables registered in the spam DB match; and, if the user has received the unblocked spam characters after the step, The type of the reported text message is analyzed, and the user can again UPDATE the user's smartphone.

In the present invention, when a smartphone user blocks an unsolicited spam text message, it installs a character recognition spam text message blocking system in a smart phone without additionally registering a spam number or a spam phrase in the spam DB, All modified spam messages can be blocked. In addition, when the new variant spam letter is entered into the letterbox without being spam blocked, the user is given a function to report the spam, collected from the central server of the control center and analyzed, and then the character recognition DB and the spam DB By updating, you can block similar new spam characters from being received again. If a lot of spam characters are blocked through this series of processes, the effect of suppressing the number of spam characters can be reduced.

The present invention will now be described in detail with reference to the accompanying drawings.

1 is a diagram illustrating a character receiving structure of a smart phone, in which a mobile communication base station sends a text message (1) and a character receiving agent (2) installed in the corresponding smart phone receives a character. The received characters are stored in the message box 3.

FIG. 2 is a flowchart showing a spam blocking process of a smartphone. When a mobile phone number is registered in a spam blocking setting of a smartphone or a spam phrase is registered, the corresponding number and the corresponding phrase are stored in the smartphone spam DB 5. Thereafter, the mobile communication base station sends out the text message (1) and the character receiving agent (2) installed in the smart phone receives the character. The agent compares the sender's phone number and message content of the received text message with the smartphone spam DB 5 and stores the same telephone number or the same phrase in the spam box 4 if there is the same telephone number, And stores it in box (3). In this case, if the sender's phone number of the spam message is changed, or if the received text message content is not the same and is received by being transformed by using special characters, alphabets, symbols, or floating, then the character receiving agent 2 transmits the smart phone spam DB 5), and stores the message in the message box. Users wishing to not receive such spam characters should continuously add spam numbers and spam phrases to the smartphone spam database (5). However, it does not block all of the recent spam messages that are received as spam sent to other numbers or transformed into visually recognizable visual phrases that do not fit the spelling.

FIG. 3 is a service structure diagram of a smartphone equipped with a character recognition spam screening system. When a text message 1 is sent from a base station of a mobile communication company, a character recognition agent 6 installed in a first stage smartphone receives a text message, Extracts alphabetic characters, special characters, symbols, numbers, and the like from the message stored in the memory of the second stage and compares the extracted characters with the character recognition DB 8 to convert them into Korean characters, vowels, alphabets, and numbers corresponding to the respective characters Step 3 Combine secondary messages by removing unrecognized alphabetic characters, special characters, symbols, and numbers. The contents of the completed second message are compared with the spam DB 5 to check whether the same word or phrase exists and sequentially comparing each first syllable of the word or phrase registered in the spam DB with the syllable of the contents of the secondary message If the first syllable exists, the second and third syllables are compared in order, and if there is a word or phrase composed of the same syllable, the fifth-level original message is stored in the spam box (4). Step 6 If you do not have the same word or phrase in Step 4 above, save it in the message box

4 is a block diagram of a character recognition DB and a spam DB. If the character is used in combination with a Hangul consonant or a vowel, the character recognition DB may not match the spelling, but the viewer may have a meaning corresponding to the actual spelling corresponding to each visual character Characters. The visual characters include alphabets, special characters, symbols, and numbers, and their actual meaning has the meaning of consonants, vowels, numbers, and alphabetic characters in Korean.

FIG. 5 shows a structure of a spam letter notification and DB update by a user. In step 6 of FIG. 3, spam is not blocked and stored in a message box. After the message is spammed by a user, the corresponding message can be reported to the control center as spam. Is stored in the spam reception DB server of the control center. After analyzing the type of new spam characters received in this way, they are reflected in the character recognition DB server and the spam block database server, and UPDATE is reflected in the character recognition DB and spam blocking database of the user's smart phone.

Spammers who send spam do not consistently send the same characters to prevent spam from being tricked, and their content is being intelligently transformed. The present invention can block spam characters more effectively with an evolving spam blocking system capable of responding to the message content that is transformed into a spam blocking system using a character recognition technology.

If the present invention is adopted as a basic spam blocking function through consultation with a manufacturer of a smartphone or a mobile communication company, it can provide a comparative advantage over the simple spam blocking function of other smart phones, And it will be helpful to reduce the transmission of illegal spam messages, which is a social problem.
