[0001] CALLING NUMBER TAMPER-PROOF BASED CALL BLOCKING CONTROL DEVICE AND METHOD [0002]

Embodiments of the present invention relate to techniques for techniques for blocking calls to illegally modulated outgoing phone numbers by the calling party.

Recently, the convenience of life has been increased due to the development of information and communication technology, but new types of criminal act that are abusing these advanced information and communication technologies and damaging people are increasing.

Especially, recently, since personal information is frequently exposed, a person who has spammed an unauthorized person by using the telephone number of each individual included in the personal information exposed, illegally advices illegal loans, (eg, phishing) are emerging as major social issues.

Generally, a criminal act using this illegal spam phone is performed by modifying the telephone number assigned to the calling telephone at the calling party to an arbitrary calling telephone number, and then making a telephone call to the receiving party. Even if the calling party's telephone number information is reported to a police station or the like, the originating telephone number is an arbitrarily modulated telephone number, and it is often impossible to accurately identify the calling party.

In addition, if a recipient sees the caller's phone number displayed on his or her phone and suspects that the phone number is a spam number, the incoming call may be refused, but as described above, recent illegal spam calls may include an originating phone number as a normal phone number It is difficult for the receiver to judge whether the telephone number is the telephone number of the spam phone by referring only to the caller telephone number displayed on the telephone of the receiver.

Therefore, in order to prevent damage caused by such an illegal spam phone, it is determined whether or not the calling telephone number of the call originated by the calling party is a deliberately modulated telephone number, and thereafter, it is suspected that the calling telephone number is an illegally modulated telephone number It is necessary to study the technique that can block the incoming call to the receiving side.

The embodiments of the present invention compare a calling telephone number of a call originated from a calling terminal with a unique charging number assigned to the calling terminal and block the call when it is determined that the calling telephone number is illegally modulated, Thereby preventing the receiving user from being exposed to the illegal spam phone indiscriminately.

The call blocking controller based on caller ID prevention according to an embodiment of the present invention is characterized in that when a call is originated from a calling terminal, information on a calling phone number of a call originated by the calling terminal is transmitted from the calling- An accounting number information receiving unit for receiving information on a unique billing number allocated in advance from the communication company server to the calling line number information receiving unit and the communication line used by the calling side terminal so as to charge the telephone charge; A number judging unit for judging whether or not the originating telephone number and the unique charging number coincide with each other; and, if it is determined that the originating telephone number matches the unique charging number, A call blocking control that does not perform blocking for the call to be forwarded It includes.

In addition, the call blocking control based on call origination number modification prevention according to an embodiment of the present invention is a call blocking control method in which, when a call is originated from a calling terminal, Receiving from the communication company server information on a unique charging number which is preliminarily assigned to charge a telephone charge for a communication line used by the calling terminal; The method comprising the steps of: determining whether the unique billing number matches the unique billing number, and if the calling telephone number and the unique billing number match, determining that the call originated by the calling terminal is normally forwarded to the called terminal And does not perform blocking.

The embodiments of the present invention compare a calling telephone number of a call originated from a calling terminal with a unique charging number assigned to the calling terminal and block the call when it is determined that the calling telephone number is illegally modulated, It is possible to prevent the receiving side user from being exposed to the illegal spam phone indiscriminately.

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

1 is a block diagram illustrating a call blocking control apparatus based on call origination number modulation according to an embodiment of the present invention.

Referring to FIG. 1, a call blocking number control apparatus 110 based on call origination number modification prevention according to an embodiment of the present invention includes an originating telephone number information receiving unit 111, a billing number information receiving unit 112, a number determining unit 113 And a call blocking control unit 114. [

First, when a call is originated from the calling terminal 130 to a predetermined called terminal, the calling telephone number information receiver 111 receives the call originated from the calling terminal 130 from the calling party switching center 140 to which the call is delivered And receives information on the telephone number.

The billing number information receiving unit 112 can bill the communication line used by the calling terminal 130 from the communication company server 150 of the communication company providing the communication service for the calling terminal 130 Information on a unique billing number assigned in advance.

Here, the billing number is a unique number allocated by the communication company to charge a telephone charge for each subscriber using the communication service, and the general billing number is the same as the telephone number assigned to the subscriber.

However, such a billing number may be different from a telephone number assigned to each subscriber. For example, in a mobile communication system, '011', '017', '016', '018', '019' When a subscriber who is using a starting mobile communication telephone number is assigned a new type of telephone number starting with '010' while changing the mobile communication terminal, a new type of telephone number is assigned to the corresponding subscriber as a billing number, The subscriber may be configured to be able to charge the telephone charge for the subscriber, but even though the subscriber has been assigned a new type of telephone number starting with '010' in the mobile communication company, 017 ',' 016 ',' 018 ',' 019 ', and the like, which are used in the past, may be used as they are.

The format of such a billing number is the same as that of the telephone number, but the calling party can arbitrarily modulate his / her originating telephone number, while such a billing number is used by the carrier to charge the subscriber based on whether the service is used in the communication line of the subscriber Since the number is unique to the subscriber, the caller can not arbitrarily modulate the billing number.

In this way, the billing number information receiving unit 112 receives information on the unique billing number, which is previously assigned to the communication company server 150 so as to charge the telephone line for the communication line used by the calling-side terminal 130 , The number determination unit 113 determines whether or not the originating telephone number and the unique identification number match each other.

If it is determined that the originating telephone number matches the unique charging number, the call blocking controller 114 interrupts the call so that the call originated by the originating terminal 130 can normally be delivered to the called terminal Do not perform.

For example, if the calling telephone number of the call originated by the calling terminal 130 received from the calling side switching center 140 is '031-123-1234', and the calling terminal 130 ) Is '031-123-1234', it is a very common case that the originating telephone number and the unique charging number coincide with each other, The call blocking controller 114 does not block the call originated by the calling terminal 130 but does not block the call to the calling terminal 130, So that the call can be normally performed.

On the other hand, when the originating phone number and the unique charging number do not match, it is an exceptional case, and therefore, it can be a basis for judging that the calling party has modulated the originating phone number.

However, if it is determined that the originating telephone number and the unique charging number do not coincide with each other, the calling telephone number is unconditionally modulated, and if the call blocking controller 114 blocks the call, The call can be blocked until the subscriber's telephone number and the billing number are set to be different from each other, so that a good user can be harmed.

Accordingly, the call blocking controller 110 based on the caller ID prevention according to the exemplary embodiment of the present invention can prevent the originating phone number from being unmodified based on whether the origination phone number matches the unique charging number Further comprising a step of determining whether the calling telephone number is a true telephone number by performing an additional verification process if the calling telephone number and the unique charging number do not coincide with each other .

In this regard, the call blocking controller 110 based on the calling number-modulation prevention according to an embodiment of the present invention may further include a band database 115. [

In the band database 115, a plurality of predetermined numerical digits composed of three digits are stored in categories of a wire telephone number band, a mobile communication telephone number band, and an Internet telephone number band.

For example, as shown in Table 1 below, the plurality of predetermined numeric strings may be stored in the band database 115 separately for each category.

In this case, according to an embodiment of the present invention, the call blocking controller 114 may include a number extractor 116, a band determiner 117, and a call blocking unit 118.

If it is determined that the calling telephone number and the unique charging number do not match with each other, the number extracting unit 116 extracts a first numeric string located in the first three digits from the digits constituting the calling telephone number, And extracts the second numerical string located in the first three digits from the digits constituting the unique billing number.

The band determination unit 117 refers to the band database 115 to determine whether the first numeric string and the second numeric string are included in the telephone number band of the same category in the band database 115. [

When the first numeric string and the second numeric string are determined not to belong to the same category of telephone number bands, the call blocking unit 118 blocks the call originated by the calling terminal 130.

For example, assume that information is stored in the band database 115 as shown in Table 1, the calling telephone number is '031-123-1234', and the unique charging number is '010-111-2222'.

At this time, since the calling telephone number and the unique charging number do not match, the call blocking controller 114 may determine that the calling telephone number is a modulated telephone number and block the call. However, If the call is blocked only because the originating telephone number and the unique billing number do not coincide with each other, the good user may be harmed. Therefore, in order to prevent such a problem, the number extracting unit 116 first extracts, 031 'which is the first three digits located in the first three digits from the number' 031-123-1234 ', and' 031 'which is located in the first three digits from' 010-111-2222 ' It is possible to extract '010' which is a 2-digit string.

Then, the band determination unit 117 refers to the band database 115 and determines that the first numeric string '031' and the second numeric string '010' are identical to each other on the band database 115 It can be judged whether or not it belongs to the band.

In this embodiment, since the first numeric string belongs to the wire telephone number band and the second numeric string belongs to the mobile communication telephone number band, the band judgment unit 117 judges that the first numeric string and the second numeric string The call blocking unit 118 may determine that the calling party's telephone number belongs to different telephone number bands and that the calling party telephone number ' 031-123-1234 'is a modulated telephone number, and can block the call originated by the calling terminal 130.

That is, the call blocking control unit 114 does not block the call unconditionally because the calling telephone number and the unique charging number do not coincide with each other, but the calling telephone number is the charging number even though the unique charging number is the mobile communication charging number Since it is extremely unusual when the band of the wire telephone number is used, it is determined that the outgoing telephone number is highly likely to be modulated, and the blocking of the call originated by the calling terminal 130 is performed, Can be prevented in advance.

Generally, as shown in Table 1, the ordinary fixed telephone number band, the mobile communication telephone number band, and the Internet telephone number band are all composed of three digits. However, in the fixed telephone number band, the fixed telephone number having the area code of Seoul is two digits whose telephone number starts with '02'.

As shown in Table 1, the band database 115 stores '02' as '02X' as indicated by '02X' in that there is an exceptional case where Seoul is an area code in the wire telephone number band. Information may be stored so as to cover all the numbers from '0' to '9'.

Therefore, if the originating telephone number or the unique identification number is '02-1234-1234', the number extracting unit 116 extracts the first three digits from the '02 -1234-1234' '021' can be extracted as the first numeric string or the second numeric string, and the band determination unit 117 determines that '021' matches the numeric string '02X' on the band database 115 It can be determined that the '021' belongs to the category of the wired telephone number band.

According to an embodiment of the present invention, the call blocking control unit 114 may further include a band identification unit 119 and a wire number determination unit 120.

If it is determined in advance by the band determination unit 117 that the first numeric string and the second numeric string belong to the same telephone number band of the same category, Check the telephone number band of the category to which the numeric string belongs.

When it is confirmed that the telephone number band of the category to which the second numeric string belongs is the wired telephone number band on the band database 115, the wire number determination unit 120 determines that the first numeric string and the second numeric string are It is possible to judge whether or not they match.

At this time, the call blocking unit 118 may block the call originated by the calling terminal 130 if it is determined that the first and second digits do not match with each other.

For example, assuming that the calling telephone number is '031-1234-1234' and the unique charging number is '032-1111-2222', the first numeric string extracted by the numeric extractor 116 is '031' , And the second numeric string may be '032'.

Since the first numeric string and the second numeric string belong to the same telephone number band called a wire telephone number band on the band database 115 shown in Table 1, the band determination unit 117 determines that the first numeric string and It can be determined that the second numeric string is a numeric string belonging to a telephone number band of the same category.

If the band determination unit 117 determines that the first number string and the second number string are numeric strings belonging to a telephone number band of the same category, The telephone number band of the category to which the second numeric string '032' belongs can be confirmed.

At this time, since '032' belongs to the category of the wire telephone number band on the band database 115 shown in Table 1, the wire number determination unit 120 determines whether the first numeric string and the second string match each other Can be determined.

At this time, since the first numeric string and the second numeric string do not coincide with each other, the call interception unit 118 determines that the calling telephone number '031-1234-1234' is likely to be the dialed telephone number modulated Thereby blocking the call originated by the originating terminal 130, thereby preventing damage to the called user in advance.

However, if the first numeric string and the second numeric string coincide with each other, the call interception unit 118 determines that the area code for the originated telephone number is unique even if the originated telephone number and the unique identification number do not coincide with each other It is determined that the possibility of modulation is low with respect to the originated telephone number, so that the call is not normally blocked for the call originated by the originating terminal 130, and the call is normally transmitted to the receiver .

According to an embodiment of the present invention, the call blocking controller 114 may further include an identification number receiver 121 and a mobile communication number determiner 122.

The identification number receiving unit 121 receives from the communication company server 150 the calling terminal 130 the telephone number band of the category to which the second numeric string belongs in the band database 115, (Mobile Identification Number) of the calling terminal 130 allocated to support the mobile communication service.

The mobile communication number determination unit 122 determines whether or not the originating telephone number matches the actual telephone number of the originating terminal 130 based on the mobile station identification number of the originating terminal 130. [

At this time, if it is determined that the outgoing phone number does not match the actual phone number of the calling terminal 130, the call blocking unit 118 may block the call transmitted by the calling terminal 130 have.

For example, assuming that the calling telephone number is '010-1234-1234' and the unique charging number is '011-111-2222', the first numeric string extracted by the numeric extractor 116 is '010' , And the second numeric string may be '011'.

Since the first number sequence and the second number sequence belong to the same telephone number band called the mobile communication telephone number band on the band database 115 shown in Table 1, the band determination unit 117 determines that the first number And the second numeric string can be determined as a numeric string belonging to the telephone number band of the same category.

If the band determination unit 117 determines that the first number string and the second number string are numeric strings belonging to a telephone number band of the same category, The telephone number band of the category to which the second numeric string '011' belongs can be confirmed.

In this case, since the '011' belongs to the category of the mobile communication telephone number band on the band database 115 shown in Table 1, the identification number receiving unit 121 receives from the communication company server 150 to the originating terminal 130 And information on the mobile station identification number of the calling terminal 130 allocated to support the communication service.

Here, the mobile station identification number is a 34-bit number that digitally displays a 10-digit telephone number assigned to a mobile station (mobile phone terminal).

When the information on the mobile station identification number for the originating terminal 130 is received from the communication company server 150 in this way, the mobile communication number determination unit 122 determines whether the mobile station identification number And determine whether the outgoing telephone number matches the actual telephone number for the calling terminal 130. [

If the actual telephone number of the calling terminal 130 is '010-2111-2222' based on the information of the mobile station identification number of the calling terminal 130 received from the communication company server 150, The communication number determination unit 122 may determine that the calling telephone number '010-1234-1234' does not match the actual telephone number of the calling terminal 130.

At this time, the call blocking unit 118 determines that the calling telephone number '010-1234-1234' does not match the actual telephone number '010-2111-2222' of the calling terminal 130, It is possible to prevent the user of the called party from being harmed by performing blocking of the call transmitted by the calling terminal 130. [

However, if the actual telephone numbers of the calling terminal 130, which can be verified based on the calling telephone number and the mobile station identification number of the calling terminal 130, are identical to each other, Even if the telephone number and the unique billing number do not coincide with each other, it is determined that the calling telephone number is the true originating telephone number of the calling party and the call is not blocked for the call made by the calling terminal 130, So that it can be transmitted normally. Therefore, the call blocking controller 110 based on the caller ID prevention according to an embodiment of the present invention uses the actual phone number assigned to the user of the calling terminal 130 in the communication company and a different billing number In the case where the user of the calling terminal 130 is normally managed, blocking is not performed for the call so that damage to the good user can be prevented from occurring.

According to an embodiment of the present invention, the call blocking controller 114 may further include an IP (Internet Protocol) address information receiver 123 and a connection area determiner 124.

The IP address information receiving unit 123 receives from the communication company server 150 the calling party's terminal 130 the telephone number band of the category to which the second numeric column belongs in the band database 115, Lt; RTI ID = 0.0 > IP < / RTI >

The access area determination unit 124 determines the Internet access area of the calling terminal 130 based on the information about the IP address assigned to the calling terminal 130 and then determines whether the Internet access area of the calling terminal 130 It is judged whether or not it is within the selected area.

At this time, the call blocking unit 118 may block the call originated by the calling terminal 130 if it is determined that the Internet access area of the calling terminal 130 is out of the predetermined area.

For example, if the calling telephone number is '070-1234-1234' and the unique charging number is '070-1111-2222', the first numeric string extracted by the numeric extractor 116 is '070' , And the second numeric string may be '070'.

Since the first numeric string and the second numeric string belong to the same telephone number band as the Internet telephone number band on the band database 115 shown in Table 1, the band determination unit 117 determines that the first numeric string and It can be determined that the second numeric string is a numeric string belonging to a telephone number band of the same category.

If the band determination unit 117 determines that the first number string and the second number string are numeric strings belonging to a telephone number band of the same category, The telephone number band of the category to which the second numeric string '070' belongs can be confirmed.

In this case, since the '070' belongs to the category of the Internet telephone number band on the band database 115 shown in Table 1, the identification number receiving unit 121 is allocated from the communication company server 150 to the calling terminal 130 Information about the IP address can be received.

When the information on the IP address assigned to the source terminal 130 is received from the communication company server 150 in this way, the access area judgment unit 124 judges whether the information about the IP address allocated to the source terminal 130 It is possible to determine whether the Internet access area of the calling terminal 130 is within a predetermined area after confirming the Internet access area of the calling terminal 130 based on the received information.

In recent years, when information on a plurality of IP addresses and information on a connection area for corresponding IP addresses are stored in a predetermined database and only the IP address of a specific terminal is confirmed based on the information, Techniques that can be verified are widely available.

Using the Internet access area determination method based on the IP address, the access area determination unit 124 determines whether or not the IP address assigned to the calling terminal 130 is an IP address assigned to the calling terminal 130 It is possible to determine whether the Internet access area of the calling terminal 130 is within the predetermined area after checking the Internet access area of the calling terminal 130 based on the information about the Internet access area of the calling terminal 130. [

If it is determined that the selected area is the Republic of Korea and the Internet access area based on the IP address of the originating terminal 130 is a country other than the Republic of Korea, It is determined that the outgoing call of the calling terminal is an illegal call and the call of the calling terminal 130 is intercepted.

However, if it is determined that the Internet access area of the calling terminal 130 is within the Republic of Korea, the call interception unit 118 may determine that the calling telephone number does not match the calling telephone number It is determined that the call is a true originating telephone number of the originating terminal 130, so that the call can be normally transmitted to the receiver without blocking the call originated by the originating terminal 130.

As a result, the call blocking control device 110 based on the caller ID prevention according to the embodiment of the present invention can prevent the calling party's phone number of the call originated from the calling terminal 130, If the number is compared and it is determined that the outgoing phone number is illegally altered, the call is blocked so that the receiving user can be prevented from being exposed to the illegal spam phone indiscriminately.

FIG. 2 is a flowchart illustrating a call blocking control method based on call origination number tampering according to an embodiment of the present invention. Referring to FIG.

In step S210, when a call is originated from the originating terminal, information on the originating terminal number of the call originated by the originating terminal is received from the originating exchange receiving the call.

In step S220, information on a unique billing number assigned in advance so as to be chargeable for the telephone charge is received from the communication company server on the communication line used by the calling-side terminal.

In step S230, it is determined whether or not the calling telephone number and the unique charging number match each other.

In step S240, if it is determined that the originating telephone number matches the unique charging number, the call is not blocked for the call so that the call originated by the originating terminal can normally be delivered to the destination terminal.

According to an embodiment of the present invention, in the call blocking control based on the calling number modulation prevention method, a plurality of selected three-digit sequence numbers are transmitted to a wired telephone number band, And maintaining the bandwidth database stored in the Internet phone number band.

If it is determined that the originating telephone number and the unique charging number do not coincide with each other after step S230, the call blocking control based on the calling number anti-tampering based on the number Extracting a first numeric string located in a first digit and a second numeric string located in the first three digits from numerals constituting the unique numeric code, The method comprising the steps of: determining whether two digit strings belong to a telephone band band of the same category on the band database; and if it is determined that the first digit string and the second digit string do not belong to a telephone band of the same category, And a step of blocking the call originated by the calling terminal.

If it is determined that the first number string and the second number string belong to a telephone number band having the same category, the call blocking control based on the calling number modulation prevention method may include a step of, If it is determined that the telephone number band of the category to which the second numeric string belongs is the wired telephone number band on the band database, Determining whether the first numeric string and the second numeric string match each other; and if it is determined that the first numeric string and the second string of digits do not match, blocking the call originated by the originating terminal The method comprising the steps of:
