Description

SIP spam blocking system and method using reputation information in internet network {SYSTEM AND METHOD FOR BLOCKING SPAM IN INTERNET USING REPUTATION SYSTEM}

The present invention utilizes reputation information of senders when providing SIP (Session Initiation Protocol) -based multimedia application services in the Internet network to protect subscribers from SIP spam. It relates to a SIP spam blocking system and method used.

The present invention is derived from the research conducted as part of the information and communication standard development support project of the Ministry of Information and Communication [Task management number: 2007-P10-41, Task name: IP application service public safety technology standard development].

Spam is damaging to many service users by sending unwanted messages and unwanted messages to many recipients. Internet telephony spam can cause time and effort to deliver, identify and delete spam, occupy the storage space of Internet telephony terminals, and financial / mental damage due to illegal and deceptive spam. In addition, the Internet telephony service provider may cause damage such as occupancy of network resources and inhibition of service activation.

In particular, the SIP protocol can be used in various applications such as VoIP service, messenger service, and all such applications are a good environment for spam, so it is important to study how to classify and block spam in the SIP protocol.

The simplest method of blocking spam is to add distinguishing information to distinguish whether a SIP request received from a SIP service receiving device is spam in a SIP INVITE message that starts a SIP protocol.

In general, however, spammers are practically impossible because they do not want to indicate that they are spam when initiating SIP communication.

As such, there is no method for blocking spam in a service using the SIP protocol.

The present invention blocks SIP spam by using reputation information on the SIP protocol which is widely used for IP multimedia services in Internet-based IPv4 or IPv6 networks.

According to a first aspect of the present invention, a system for blocking SIP spam in an Internet network, wherein when a SIP message is received from any caller terminal in connection with a plurality of caller terminals, a reputation score for the caller terminal is requested. An outgoing router for transmitting a SIP message to which the provided reputation score is added; and a reputation information storage for storing a reputation score for a plurality of callers provided from terminals in the Internet network, and based on a request of the originating router. A reputation management apparatus for retrieving a reputation score for the arbitrary calling party terminal from the reputation information store and providing the reputation score to the originating router, receiving a SIP message added with the reputation score from the originating router, and receiving a reputation score in the SIP message and The number of spam messages to SIP through comparisons between preset reputation scores. It includes the own terminal.

According to a second aspect of the present invention, a SIP spam blocking method in an Internet network is installed in the Internet network and includes a reputation information storage having a reputation score for a plurality of callers provided from terminals in the Internet network. A method for preventing SIP spam using a device, the method comprising: receiving a SIP message from an originating terminal at an originating router, requesting a reputation score for the arbitrary originating apparatus from the originating router, and requesting the originating router. Retrieving a reputation score for the caller terminal from the reputation information store and providing the reputation score to the calling router; transmitting a SIP message to which the reputation score provided by the reputation management device is added to the receiver terminal; Between the reputation score in the SIP message and a preset reputation score in the receiver terminal By comparing comprises the step of processing the SIP spam messages.

The present invention establishes a reputation management apparatus in the central part of the Internet, collects reputation scores for SIP callers from Internet users, and defines reputation scores for SIP callers based on the collected information. By adding a reputation integer, the next SIP request recipient can view the reputation score and block the SIP request, protecting the subscriber from SIP spam.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. In addition, in describing the present invention, when it is determined that the detailed description of the related known configuration or function may obscure the gist of the present invention, the detailed description thereof will be omitted.

According to a preferred embodiment of the present invention, a reputation management apparatus is established in the central part of the Internet to collect reputation information on SIP callers from Internet users, and the reputation scores are defined on SIP callers based on the collected information. This section describes the system and operation of the next SIP request receiver to view the reputation information and block the SIP request by adding the reputation integer defined in the message.

1 is an Internet network structure diagram for blocking SIP spam to which a reputation management apparatus is applied according to an exemplary embodiment of the present invention, and is based on the Internet 100 that can operate in both an IPv4 network or an IPv6 network.

In order to prevent the network manager 101 managing the Internet 100 from exploiting SIP-based IP application multimedia services that are being serviced in its network from spam to protect its network, a SIP-based spam blocking system is used. In the present invention, the network manager 101 establishes the reputation management apparatus 102 and then uses the same to block the SIP-based spam to manage the Internet 100 network.

In the SIP-based Internet 100 network according to the present invention as described above, a caller terminal 103 of a caller who can be a spammer, and an outgoing ESE (Edge Service Entity, hereinafter referred to as 'ESE') that services a caller function 104 ), A receiver E 106 of the receiver, and a receiving ESE 107 that enables Internet services to the receiver terminal 106. The originating ESE 104 functions as a connection router to enable Internet service and includes a local reputation information store 105 in which a list of local reputation information is stored.

When the originating ESE 104 is connected to a plurality of caller terminals 103 and receives a SIP message from any caller terminal 103, the originating ESE 104 requests the reputation management device 102 to request reputation information for any caller terminal 103. Then, the SIP message to which the reputation information provided from the reputation management apparatus 102 is added is transmitted to the receiver terminal 106.

The reputation management apparatus 102 stores reputation information for a plurality of callers provided from terminals in the Internet 100 network, and, based on a request of the originating ESE 103, for any caller terminal 103. The reputation information is retrieved and provided to the calling ESE 103.

The receiver terminal 106 receives a SIP message with reputation information added from the originating ESE 104 and processes the SIP message by comparing the reputation information in the SIP message with preset reputation information.

The functions of the flatbed management apparatus 102, the originating ESE 104, the receiving ESE 107, the calling party terminal 103, and the receiving terminal 106 will be described with reference to FIG.

2 is a diagram illustrating a functional structure of the flat plate management apparatus 102, the originating ESE 104, the receiving ESE 107, the sender terminal 103 and the receiver terminal 106 according to an embodiment of the present invention.

As shown in FIG. 2, the flat plate management apparatus 102 includes a flat plate information storage 201 that stores flat plate information about a plurality of callers, a flat plate collection managing unit 202 which maintains a flat plate information store 201, Overall management of the network related to the reputation management apparatus 102 such as setting a policy for adjusting specific reputation information or deleting and managing unused reputation information as a function for managing the Internet 100 network using the reputation management unit 102. And a reputation policy setting unit 203 and an ESE reputation information management unit 204 which perform a function.

The reputation collection management unit 202 updates the reputation information store 201 using the reputation information of the sender as the reputation information about the sender is received from the terminals of the Internet 100 network.

The reputation policy setting unit 203 provides the network manager 101 with a function for setting a policy for adjusting or deleting specific reputation information stored in the reputation information store.

The ESE reputation information 204 stores reputation information held by each originating ESE 104 in the Internet 100 network. The ESE reputation information 204 stores arbitrary reputation information as any reputation information in the reputation information store 201 is changed. Use to change the originating ESE 104 holding any reputation information in the Internet 100 network and the local reputation information store 105 in it.

The originating ESE 104 is a reputation information management 213 that maintains and manages the local reputation information store 105 that is being serviced, a network reputation information request 212 that requests reputation information from the reputation management apparatus 102, There is a function to add reputation information 214 to add reputation information to a SIP message, such as a SIP INVITE packet.

The receiver terminal 106 may define the reputation information of the sender for the SIP INVITE message received by the user (recipient) of the reputation information notification unit 223 for displaying the reputation information on the screen, and the receiver. Automatically receives the SIP INVITE message with reputation information below a certain level from the reputation input unit 224 and the receiver terminal 106, which provides an interface for generating reputation information for the sender after communicating with the sender. SIP rejection policy unit 221 for setting the rejection-related policy to be rejected, and rejection SIP information storage 222 that stores the contents of the SIP INVITE automatically rejected.

In the network structure having the above configuration, when there is no reputation information in the SIP INVITE message, the process of transmitting the reputation information to the receiver terminal 106 by adding the reputation information to the SIP INVITE message will be described with reference to FIG. 3. do.

First, as shown in FIG. 3, when the sender terminal 103 transmits a SIP INVITE packet to the receiver terminal 106 to start communication using SIP (S300), the originating ESE 104 sends a SIP INVITE message. It is determined whether the reputation information exists, and if the reputation information does not exist, request the sender reputation information to the reputation management apparatus 102 (S302). The reputation management apparatus 102 detects the sender reputation information in the reputation store 201 and transmits it to the originating ESE 104 (S304).

The originating ESE 104 stores the received reputation information in the local reputation information store 211 and adds the reputation information to the SIP INVITE message received from the caller terminal 103 (S306). The INVITE message is transmitted to the receiver terminal 106 (S308). The receiver terminal 106 displays reputation information on the screen of the receiver terminal 106 when processing the SIP INVITE message (S310).

On the other hand, when the sender reputation information exists in the local reputation information store 211 of the originating ESE 104, as shown in Figure 4, the originating ESE receiving the SIP INVITE packet from the sender terminal 103 (S311) 104 retrieves the reputation information of the sender from the local reputation information store 211 and adds it to the SIP INVITE packet (S312), and the SIP INVITE packet to which the reputation information is added is transmitted to the receiver terminal 106 (S313). do. The receiver terminal 106 displays the reputation information included in the SIP INVITE packet on the screen when processing the SIP INVITE packet (S314).

A process of inputting and transmitting reputation information from the receiver terminal 106 to the Internet 100 network will be described with reference to FIG. 5.

As shown in FIG. 5, when a user inputs the reputation information to newly define the reputation information of the sender for the received SIP INVITE using the reputation input 224 function in the receiver terminal 106 (S320). The input reputation information is transmitted to the reputation management apparatus 102 (S322). The reputation collection management function 202 of the reputation management apparatus 102 updates the reputation information of the sender stored in the reputation information store 201 by recalculating the reputation information, that is, the received reputation information (S324).

If the reputation management apparatus 102 searches for the ESE reputation information 204, if there is an originating ESE 104 having the reputation information (the reputation information corresponding to the sender in the received reputation information), the originating ESE is present. The recalculated reputation information is forwarded to S104 (S326) to update the local reputation information store 211 in the originating ESE 104 (S328).

Here, the reputation information may be information such as a number format or a rejection or permission.

Meanwhile, the process of rejecting the SIP INVITE message based on the SIP blocking policy 221 by the receiver terminal 106 will be described with reference to FIG. 6.

As shown in FIG. 6, the receiver sets a reputation level for rejecting a SIP message using the SIP blocking policy 221 function in the receiver terminal 106 (S330).

When the sender terminal 103 sends the SIP INVITE packet (S332), the calling ESE 104 adds the reputation information of the sender to the SIP INVITE message (S334), and then adds the SIP INVITE packet including the reputation information to the receiver terminal 106. (S336). The receiver terminal 106 compares the reputation information set in the SIP INVITE packet with the reputation level previously set, and if the reputation level of the received SIP INVITE packet is lower (S338), the receiver terminal 106 sends a rejection message to the sender terminal 103 as a SIP response message. It transmits (S340).

As such, the receiver terminal 103 may stop spam because it does not respond when all the received spam messages are received.

The structure of the IPv4 and IPv6 packet to which reputation information is added is demonstrated with reference to FIG.

In general, reputation information is added only to a SIP INVITE message and may be added to the header or body of a packet.

However, most preferably, the reputation information is added to the IP header, and when the Internet 100 in which the present invention operates is IPv4, the reputation information is added to the Options 403 of the IPv4 header, as shown in FIG. 7A. can do. The new number is assigned to Number 406 of Options 403 to know that there is reputation information in the network, and it can be ignored for networks that do not know reputation information. The structure of adding reputation information to the Options 403 in the originating ESE 104 fills in the values of 404, 405, 406, 407, and 408 in FIG. 7A, where Flag 404 means that Options 403 will be used. Is 1 and Class (405) is used as 0 for control, and Number (406) is defined as a new number to distinguish it as reputation information, and Option Length (407) is the length of reputation score 408, which can be expressed from 0 to 65535. Set to 2 to make it work. The reputation score 408 is then a score represented by 0-65535.

When the reputation information is added by the originating ESE 104, an option 403 is added. The length of the IP packet header 401 and the part of the header checksum 402 need to be modified.

As shown in FIG. 7B, the Internet 100 in which the present invention operates may add a reputation score at the originating ESE 104 to the Destination Options Header 451 in the case of IPv6. The SIP INVITE packet is added to the IPv6 header just before the TCP header when the reputation score is added to the Destination Options Header 451 in the packet in TCP. So when you add a reputation score to the Destination Options Header (451), it fills in the values of 452, 453, 454, and 455. Next Header (452) adds the Destination Options Header (452) just before the TCP header, so TCP can be displayed. 006 will be entered, Length (453) will be 5, and it will be a new delimiter to mark reputation score in Option Type (454). Option Length (455) will be 2, which is the same value as Option Length (407) of IPv4, and reputation score 456 is the same as the reputation score 408 of IPv4 to become the reputation score of the SIP INVITE packet.

A process of blocking spam using the reputation system in the originating ESE 104 will be described with reference to FIG. 8.

As shown in FIG. 8, when the originating ESE 104 receives the SIP INVITE message from the local terminal that can be identified from the originating address (S500), whether the reputation information for the originating address exists in the local reputation information store 211. Determine (S502).

As a result of the determination in S502, when there is no reputation information, the originating ESE 104 transmits a message requesting caller reputation information to the reputation management apparatus 102 (S504), and waits for a predetermined time (S506).

If the originating ESE 104 does not receive a response from the reputation management apparatus 102 after a certain time has elapsed, the SIP INVITE message without the reputation information added is transmitted to the receiver terminal 106 (S508), otherwise After updating the local reputation information store 211 using the reputation information provided from the management device 102 (S512), the received reputation information is added to the SIP INVITE message and then transmitted to the receiver terminal 106 (S514). ).

On the other hand, if it is determined in S502 that the reputation information exists, the originating ESE 104 extracts the reputation information from the local reputation information store 211 and adds it to the SIP INVITE message and transmits it to the receiver terminal 106 (S514).

If there is no utilization of any reputation information stored in the local reputation information store 211 for a preset time or when a request for deleting the reputation information is received from the reputation management device 102, the originating ESE 104 sends a request to the local reputation information store 211. The reputation information is deleted (S516 and S518).

A process for blocking spam in the reputation management apparatus 102 will be described with reference to FIG. 9.

As shown in FIG. 9, the flat panel management apparatus 102 holds network-wide flat panel information, which may exist permanently according to the management of the network operator. The other information held by the reputation management device 102 also includes information on which reputation information the originating ESE holds, that is, ESE reputation information. This information is automatically destroyed after a certain amount of time. However, the automatic extinction time for each information in the ESE reputation information 204 should match in terms of operation management between the originating ESE 104 and the reputation management apparatus 102.

If there is a request (S600) for caller reputation information in any originating ESE 104, the reputation management apparatus 102 determines whether caller reputation information exists in the reputation information store 201 (S602), and the determination result of S602. If the sender reputation information exists, it is provided to the arbitrary originating ESE 104 (S604), and then the optional ESE reputation information is updated through the ESE reputation information management unit 204 (S606).

On the other hand, as a result of the determination in S602, when there is no caller reputation information, the reputation management apparatus 102 transmits a default value to the reputation information (S608).

When caller reputation information is received from an arbitrary receiver terminal 106 (S610), the reputation management apparatus 102 recalculates and stores the received reputation information in its own reputation information store 201 (S612).

Then, the ESE reputation information management unit 204 of the reputation management apparatus 102 updates the ESE reputation information based on the received caller reputation information when the received caller reputation information exists in the ESE reputation information managed by the user (S614). And transmits the modified reputation information to the originating ESE 104 (S616) to update the local reputation information store 211 of the originating ESE 104.

Meanwhile, when there is a request for deleting specific reputation information (S618) according to a network reputation information operator or an operation policy, the reputation management apparatus 102 deletes specific reputation information from the reputation information store 201 (S620), and the ESE reputation. If the specific reputation information exists in the information, the request is made to delete the specific reputation information from the originating ESE 104 (S624) to update the local reputation information store 211 of the originating ESE 104.

Then, the reputation management apparatus 102 deletes the specific reputation information in the ESE reputation information (S626).

On the other hand, if there is a request to change the specific reputation information according to the network plate information operator or operation policy S618 to S626 and the process does not delete the reputation information only delete.

A process of blocking spam at the receiver terminal 106 will be described with reference to FIG. 10.

As shown in FIG. 10, when the receiver terminal 106 receives the SIP INVITE packet (S700), it is determined whether reputation information exists in the SIP INVITE packet (S702).

As a result of the determination in S702, when the reputation information exists, the receiver terminal 106 compares the value of the reputation information with a predetermined value (S704).

As a result of the comparison of S704, when the reputation information value is smaller than the preset policy value, the receiver terminal 106 stores the rejected SIP INVITE message in the rejected SIP information store 222 (S706) and then rejects the SIP INVITE. The rejection response message (603 message) is transmitted to the caller terminal 103 (S708), otherwise, the SIP INVITE message is processed after displaying the reputation information on the screen (S710 S712).

On the other hand, if the reputation information does not exist, the receiver terminal 106 performs the S712.

In addition, when the user inputs the reputation information for the specific caller (S714), the input reputation information is provided to the reputation management device 104 (S716). If the reputation information is positive (S718), and if the reputation information is negative, the reputation information input according to the user policy is set in the SIP blocking policy unit 221 (S720). Here, the negative reputation information means that the user defines a policy in the receiver terminal 106. The value specified as a value indicating that the policy value does not receive a SIP INVITE message from the beginning for the reputation information below a specific value. to be. Thus, the rejection related information of the SIP INVITE having a low reputation information value is stored in the user's SIP rejection information store 222. The reason for storing the rejected communication contents is to allow the user to recover the wrong rejected communication later and receive the SIP INVITE later.

If the user receives a request for rejection / rejection of content (S722), the content of the reception / rejection is collected (S724) and the content of the reception / rejection is displayed on the user screen (S726). In addition, the user may reset the SIP blocking policy unit 221 (S728).

According to the present invention, by establishing a reputation management device 102 in the center of the Internet 100 to collect reputation information for the SIP caller from the Internet users, and to define the reputation score for the SIP caller based on the collected information, By adding a reputation integer defined in future messages for SIP requests, the next SIP request recipient can view the reputation information and block the SIP request, effectively blocking the SIP spam request.

It has been described so far limited to one embodiment of the present invention, it is obvious that the technology of the present invention can be easily modified by those skilled in the art. Such modified embodiments should be included in the technical spirit described in the claims of the present invention.
