Description

Spam protection system and method and spam authentication device therefor {SYSTEM AND METHOD FOR BLOCKING SPAM CALL AND SPAM AUTHENTICATION APPARATUS THEREFOR}

The present invention relates to spam call blocking, and more particularly, to a spam blocking system and method for providing a spam call blocking service for a wired communication terminal and a spam authentication device therefor.

With the development of communication technology, the spread of mobile communication terminals has increased, and thus, more rapid communication and transmission of various multimedia contents by using mobile communication terminals are possible. However, behind the development of the communication technology, spam calls for advertising or promotion for unspecified communication subscribers have been greatly increased, causing a lot of damage to communication subscribers.

For example, a spam call to advertise various products, especially loans, can be faked as a regular phone to deceive that it's a spam call, or to make the phone ring once and then hang up in the same way you make a call. In other words, it is damaging in a way that stimulates the curiosity of the subscriber and causes the subscriber to call again.

On the other hand, in recent years, with the expansion of the high-speed Internet infrastructure facilities to enable high-speed data communication, Internet telephony services using the Internet network are widely used. Unlike ordinary landline telephones using PSTN-Public Switched Telephone Networks, Internet telephones do not incur charges in sections within the Internet network, so the cost of calls is so low that their use increases rapidly in homes and offices. There is a trend. In other words, the use of landline telephones has gradually decreased due to the spread of mobile communication services.

As the use of Internet phones increases, spam calls increase. As described above, the Internet phone is not only low in cost but also available abroad at the same cost as in Korea, and there are an increasing number of cases of illegal phone fraud such as voice phishing using Internet phone in China. In addition, the Internet phone uses an identification number, for example, "070", so that general communication subscribers confuse the phone number of the spam phone with the identification number of the Internet phone and become more defenseless against the spam phone.

Various attempts have been made to block such spam calls. Representatively, Korean Patent No. 10-869243 outputs an incoming bell only when the incoming call is maintained for a certain time by delaying the incoming call for a predetermined time when a call is made to an outgoing number not registered in the phone book of the telephone. Or, if a call is received from an outgoing number that is not registered in the phone book, register the outgoing number in the spam management memory temporarily, and then instruct the other party to call back. I'm proposing.

In addition, Korean Laid-Open Patent No. 10-2003-30516, when a telephone call is made, determines whether the registered call reception number and the calling number are the same, and if it is the same, checks whether the reception time is the second reception rejection time. It is proposed a method of blocking the call of the calling number only when.

However, the conventional spam blocking method is a method of using a phone book stored in a telephone, which is useful for communication subscribers who call only a limited number of people, and is not useful for communication subscribers who call with an unspecified number. not. It is practically impossible to store in the phonebook all of the unspecified numbers that are likely to make a call. In particular, it is expected that the number of telephone numbers will increase exponentially due to the spread of Internet telephones and the spread of mobile communication terminals. However, it is inconvenient for a user to register many telephone numbers in the telephone directory to prevent spam. In addition, the first method of the conventional anti-spam method is to guide the other party to call again to prevent spam, when a direct person such as voice phishing to make a spam call is still exposed unprotected.

The present invention was devised to solve the above problems, and uses a Calling IDentification (CID) service in a communication network without the user having to register a spam telephone number in advance with a wired communication terminal such as an Internet telephone. Accordingly, an object of the present invention is to provide a spam blocking system for providing a spam blocking service to a wired communication terminal, a method thereof, and an apparatus therefor.

Referring to FIG. 1, the spam blocking system according to the present embodiment includes a calling terminal 110, a called terminal 120, a communication network 130, and a spam authentication center 150. The communication network 130 may be one or a combination of a public telephone network, an internet network, or a mobile communication network.

The calling terminal 110 and the called terminal 120 are terminals capable of a voice or video call, and are connected through the communication network 130 to make a voice call or a video call. The calling terminal 110 and the called terminal 120 include a display device for displaying the status information of the terminal and the video of the other party during a video call, and an input device for receiving a signal for operating the terminal from the user. Since the basic components of these terminals are well-known components, description thereof will be omitted.

Referring to FIG. 1, when an outgoing call originated from the calling terminal 110 is received by the called terminal 120 through the communication network 130, the called terminal 120 extracts the calling party's telephone number from the calling call and communicates with the communication network 130. Spam authentication request to the spam authentication center 150 through the (). The spam authentication center 150 checks whether the sender's telephone number requested for spam authentication is registered as a spam number, and transmits the result of the spam authentication to the destination terminal 120 so that it is displayed on the display device.

In detail, as illustrated in FIG. 1, the spam authentication center 150 includes a spam authentication request receiver 151, a spam authentication processor 153, a spam authentication result transmitter 154, and a spam number DB 152. do.

First, the spam number DB 152 stores spam reported spam telephone numbers. The spam certification center 150 is connected to the illegal spam response center (www.spamcop.or.kr), the Korea Information Security Agency's illegal spam response center, and the spam report center of each wired / wireless communication company to collect spam phone numbers reported as spam numbers. To store the spam number DB (152).

The spam authentication request receiving unit 151 receives a spam authentication request message including a caller's telephone number extracted from the incoming call from the called terminal 120 receiving the incoming call, and sends the caller's telephone number to the spam authentication processor 153. To pass).

When the spam authentication request message is received through the spam authentication request receiver 151, the spam authentication processing unit 153 inquires from the spam number DB 152 whether the sender's phone number for which the spam authentication is requested is registered as a spam number. And transmits the result to the spam authentication result transmission unit 154.

The spam authentication result transmission unit 154 receives the spam number registration inquiry result for the caller's telephone number from the spam authentication processing unit 153, and uses the received spam number registration inquiry result as the spam authentication result as the communication network 130. Through the transmission to the destination terminal 120. Preferably, the spam authentication result transmitter 154 transmits the voice message and the text message to the called terminal 120 as a spam authentication result. The voice message is a guide message as to whether the caller's telephone number is registered as a spam number, and the text message is a guide message to be displayed on the display device of the called terminal 120.

The communication unit 121 extracts the caller's phone number from the incoming call and delivers it to the spam management unit 123 when the incoming call is received.

When the spam manager 123 receives the caller's phone number from the communication unit 121, the spam manager 123 transmits a spam authentication request message including the caller's phone number to perform a spam authentication process on the received caller's phone number. Is transmitted to the spam authentication center 150).

In addition, when the spam authentication result message for the spam authentication request message is transmitted from the spam authentication center 150, the spam management unit 123 receives the spam authentication result message through the communication unit 121 and then through the display device and the speaker. The spam authentication result for the caller's phone number is output.

Preferably, the spam management unit 123 outputs a text message through the display device, and outputs a voice guidance message through the speaker. For example, it outputs a voice and text message such as "Call now 010-111-1111 is a spam call."

In addition, the spam manager 123 may output the spam authentication result through the display device and the speaker, and determine whether to accept the call from the caller's telephone number from the user. The spam manager 123 may output a spam authentication result as a voice and text message, and may additionally inquire whether to answer a call and receive a response by touch input or key button input. But you don't have to confirm whether you accept the call.

Preferably, the spam management unit 123 rings the incoming bell when the spam authentication result is received from the spam authentication center 150 without receiving the incoming bell until the spam authentication result is received when the incoming call is received. This is to exclude the possibility that the called party can receive the spam call by ringing before the spam authentication is completed.

When the call processing unit 125 receives a hook off signal from the user or receives a call acceptance signal for the caller's telephone number from the spam management unit 123, the call processing unit 125 transmits the calling terminal 110 through the communication unit 121. Transmit a call response signal to form a call path with the calling terminal (110). The call processing unit 125 outputs the caller's voice received from the caller terminal 110 through the speaker, receives the caller's voice from the microphone, and transmits the caller's voice to the caller terminal 110.

2 is a flowchart illustrating a spam call blocking method in the spam blocking system of FIG. 1.

Referring to FIG. 2, the calling terminal 110 transmits a call to the called terminal 120 and the transmitted call is transmitted to the called terminal 120 through the communication network 130 (S201). The communication unit 121 of the called terminal 120 receiving the outgoing call extracts the caller's telephone number from the outgoing call (S203), and the spam manager 123 of the called terminal 120 includes the extracted caller's telephone number. The spam authentication request message is transmitted to the spam authentication center 150 through the communication network 130 (S205). At this time, the spam management unit 123 of the called terminal 120 does not ring the incoming call until the spam authentication result is received.

The spam authentication center 150 receiving the spam authentication request message checks whether the caller's phone number is registered as a spam number in the spam number DB 152 using the caller's phone number included in the spam authentication request message. (S207). In detail, the spam authentication request receiving unit 151 of the spam authentication center 150 receives the spam authentication request message, extracts a sender's telephone number from the spam authentication request message, and delivers it to the spam authentication processing unit 153. The spam authentication processing unit 153 checks whether the caller's telephone number is registered in the spam number DB 152 as a spam number.

The spam authentication result transmitting unit 154 of the spam authentication center 150 receives the spam authentication result for the caller's telephone number from the spam authentication processing unit 153 and receives the spam authentication result through the communication network 130. 120) (S209). Preferably, the spam authentication result comprises a voice prompt message and a text message as to whether the caller's telephone number is a spam number, and the spam authentication result is transmitted through a data channel.

The spam manager 123 of the called terminal 120 receives the spam authentication result transmitted from the spam authentication center 150 through the communication unit 121, and outputs the received spam authentication result (S211). Preferably, the spam manager 123 outputs the voice guidance message received as a spam authentication result through the speaker, the text message to the display device, and outputs the incoming bell. The spam authentication result is, for example, a message such as "Call is now spam." In addition, the spam management unit 123 outputs the spam authentication result and notifies the user that the incoming call rings.

Subsequently, the spam management unit 123 of the called terminal 120 confirms whether the user accepts the call of the caller's telephone number (S213), and when the user accepts the call, a hook off, for example, the user picks up the receiver, etc. off) when receiving the signal, the spam management unit 123 transmits the signal according to the call processing unit 125, the call processing unit 125 of the destination terminal 120 is a call to the calling terminal 110 of the caller's telephone number The call is started by forming a furnace (S215).

When the call processing unit 125 of the called terminal 120 receives a hook on signal such as a user hanging up the handset, or receives a signal regarding the user's rejection of the call from the spam management unit 123, End the call (S217). The spam management unit 123 of the called terminal 120 outputs a spam authentication result and at the same time guides whether or not to accept the corresponding call and transmits a signal related to this to the call processing unit 125 to reject the call. To end the call. For example, the spam manager 123 outputs a voice message and / or a text message of “Please press 1 when rejecting a call” as a guide on whether to accept a call, and receives a key input signal.

As described above, when the incoming terminal 120 does not need to separately register a spam number in the phone book, the incoming caller's telephone number of the incoming call is spammed to the spam authentication center 150 through the communication network 130 before ringing the incoming bell. Check whether it is a number and print a guide message accordingly so that the user can recognize the illegal spam call in advance and do not answer the call.

3 is a diagram showing the configuration of a spam blocking system according to another embodiment of the present invention.

The spam blocking system of this embodiment with reference to FIG. 3 adds a spam report processor 311 and a personal rejection number DB 313 to the spam authentication center 310. In FIG. 3, the same reference numerals are attached to the same components as those in FIG. 1, and description thereof is omitted.

As described with reference to FIGS. 1 and 2, after an incoming call is received from the calling terminal 110 to the called terminal 320, the spam authentication center 310 performs a spam authentication process on the calling telephone number. As a result of the spam authentication processing, when it is determined that the caller's telephone number is not a spam number and the called party starts a call with the calling terminal 110 and ends the call, the spam report processing unit 311 of the spam authentication center 310 performs a communication network ( The spam report logic for the call ended the call to the destination terminal 320 through 110.

The spam report processing unit 311 receives an inquiry message, for example, a voice message and a text message, via the communication network 110 to inquire whether the call is a spam call or whether the call is not a spam call but is a phone that you want to reject personally. 320, and receives a response message from the called terminal 320.

The spam report processing unit 311 registers the caller's telephone number in the spam number DB 152 or the personal rejection number DB 313 based on the response message received from the called terminal 320. When the spam report processing unit 311 receives a response message for the spam number from the called terminal 320, the spam call number registered in the spam number DB 152, the response to the personal rejection from the called terminal 320 Upon receiving the message, the caller registered telephone number is registered in the personal rejection number DB 313.

In addition, the spam report processing unit 311 registers the number of spam reports for the caller's phone number that is reported as spam and registered in the spam number DB 152 together with the spam number DB 152, and the number of spam reports is a predetermined number or more. If the other phone number of the subscriber using the caller's phone number is retrieved and registered in the spam number DB (152). To this end, the spam report processing unit 311 performs a procedure of confirming subscriber information in association with a customer information system of each communication service provider.

The personal rejection number DB 313 classifies and stores the caller's telephone number registered as the personal rejection number by the spam report processing unit 311 based on the information of the called party who has registered the caller's telephone number as the personal rejection number.

Meanwhile, the spam authentication processing unit 153 receives an incoming call at the called terminal 320, and the spam authentication request for the caller's telephone number of the called call is received from the spam manager 321 of the called terminal 320. ), The spam number DB 152 checks whether the caller's phone number is a spam number, and also checks the personal reject number DB 313 whether the caller's phone number is a personal rejection number.

The spam authentication result transmission unit 311 transmits the spam authentication result processed by the spam authentication processing unit 153 to the destination terminal 320 through the communication network 130, wherein the spam authentication processing unit 153 processes the When the spam authentication result for the caller's phone number is confirmed as the personal rejection number, the spam authentication result indicating the personal rejection message is transmitted to the called terminal 320. When the caller's phone number is a spam number, the caller's phone number has been described with reference to FIGS. 1 and 2.

On the other hand, the spam management unit 321 of the terminating terminal 320, when the incoming call is received from the originating terminal 110, the spam authentication request message for the caller's telephone number of the incoming call through the communication network 130 before ringing the incoming bell If the sender phone number is a spam number, it is processed as described with reference to Figs. 1 and 2, and the caller phone number is registered as a personal rejection number. 310, a message indicating the personal rejection number is received and output to the user.

4 is a flowchart illustrating a spam report method in the spam blocking system of FIG. 3.

Referring to FIG. 4, as described with reference to FIG. 2, after the call is received from the calling terminal 110 to the called terminal 320, a spam authentication process is performed, so that the caller's telephone number of the received call is not a spam number. If confirmed, the user of the called terminal 320 initiates a call to make a call with the caller of the calling terminal 110 and ends the call (S401).

When the call is terminated, the spam report processing unit 311 of the spam authentication center 310 transmits a blocking inquiry message for the caller's telephone number to the called terminal 320 through the data channel of the communication network 130 ( S403). The blocking inquiry message is a message for inquiring whether the caller's telephone number is a spam number or a personal rejection number, and may include a voice message and a text message.

The spam manager 321 of the called terminal 320 receives the blocking query message through the communication unit 121 and outputs the blocking query message. The voice message is output through the speaker and the text message is displayed on the display device.

The spam management unit 321 of the called terminal 320 receives the user's response to the blocking inquiry message, and checks whether the response is a spam blocking response to the caller's telephone number (S405). The spam blocking response message is transmitted to the spam authentication center 310 (S409).

On the other hand, the spam management unit 321 of the terminating terminal 320, if the user's response to the blocking query message is not a spam block response checks whether it is a personal block response (S407), if the personal block response, the spam authentication The personal cutoff response message is transmitted to the center 310 (S409).

As described above, the spam report processing unit 311 of the spam authentication center 310 that has received a response to the blocking inquiry message from the called terminal 320 registers the caller's telephone number as a spam number according to the received response message. By registering as a personal rejection number of the user of the called terminal 320 to block the call by the caller's telephone number to the called terminal 320 (S411).

On the other hand, the spam management unit 321 of the terminating terminal 320, if there is no response from the user to the blocking query message transmits a non-response message to the spam authentication center 310 (S413).

As such, the user of the called terminal 320 confirms that it is not a spam call and receives a call, but if the call is a spam call, the user can report a spam call by a simple key input after the call is terminated. You will not answer the call. In addition, the user of the receiving terminal 320 is registered as a personal rejection number with a simple key input, even if the call is not a spam call, but personally refused to receive the call after receiving a call from the same caller's phone number It allows you to confirm that a call has been received from the rejected number, preventing you from making unwanted phone calls.

Conventionally, although the communication terminal has a reception rejection function, the function of the communication terminal is complicated and it is very difficult to find a desired function, so that users who are not good at the operation of the communication terminal cannot easily use the reception rejection function. After the phone call is finished, you can follow the instructions to reject the call with a simple keystroke.

Referring to FIG. 5, the calling terminal 110 transmits a call to the called terminal 320 and the sent call is transmitted to the called terminal 320 through the communication network 130 (S501). The communication unit 121 of the called terminal 320 receiving the outgoing call extracts the caller's telephone number from the outgoing call (S503), and the spam manager 323 of the called terminal 320 includes the extracted caller's telephone number. The spam authentication request message is transmitted to the spam authentication center 310 through the communication network 130 (S505). At this time, the spam management unit 323 of the called terminal 320 does not ring the called ring until the spam authentication result is received.

Upon receiving the spam authentication request message, the spam authentication center 310 checks whether the caller phone number is registered as a spam number in the spam number DB 152 using the caller phone number included in the spam authentication request message. (S507). In detail, the spam authentication request receiving unit 151 of the spam authentication center 310 receives the spam authentication request message, extracts a caller's phone number from the spam authentication request message, and delivers it to the spam authentication processing unit 153. The spam authentication processing unit 153 checks whether the caller's telephone number is registered in the spam number DB 152 as a spam number.

If the caller's telephone number is not registered as a spam number, the spam authentication processing unit 153 of the spam authentication center 310 rejects the individual whose caller's telephone number is registered by the user of the called terminal 320. It is checked in the personal rejection number DB 313 whether it is a number (S509).

The spam authentication result transmitting unit 154 of the spam authentication center 310 receives the spam authentication result message through the communication network 130 based on the result of the verification of the spam authentication processing unit 153 in steps S507 and S509. (S511). Preferably, the spam verification result comprises a voice prompt message and a text message as to whether the caller's telephone number is a spam number or a personal rejection number, and the spam verification result is transmitted via a data channel.

The spam management unit 321 of the called terminal 320 receives the spam authentication result transmitted from the spam authentication center 310 through the communication unit 121, and outputs the received spam authentication result (S513).
