Description

Technical Field

[0001] The embodiments of the present invention relate to the field of communication security technology, and in particular, to a positioning method, device, equipment and medium for a GOIP remote control end. Background Art

[0002] With the continuous development of information security technology, GOIP (Global System for Mobile Over Internet Protocol) has gradually become the main implementation method of abnormal calls. Therefore, accurate detection and positioning of GOIP devices and their remote control ends are of great significance for improving communication security.

[0003] Currently, existing GOIP detection methods mainly include identification based on black IMEI (International Mobile Equipment Identity) features and aggregated detection based on LAC (Location Area Code) and CI (Cell Identity). Among them, identification based on black IMEI features mainly finds out the IMEI number segments according to the IMEI numbers of historically discovered GOIP devices, and then searches for new GOIP devices using these IMEI number segments and the mobile phone numbers associated with these new GOIP devices. The aggregated detection based on LAC and CI mainly realizes the detection of GOIP devices with fixed positions on the same day by establishing a corresponding baseline of the number of daily active numbers for each LAC-CI.

[0004] The inventors found in the process of implementing the present invention that the existing technology can usually only detect the positions of GOIP devices, but cannot locate the remote control ends of GOIP devices, so it is impossible to substantially strike such GOIP users and effectively ensure communication security.

[0027] Embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although some embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be construed as limited to the embodiments set forth herein. On the contrary, these embodiments are provided to more thoroughly and completely understand the present invention. It should be understood that the drawings and embodiments of the present invention are only for exemplary purposes and are not used to limit the protection scope of the present invention.

[0028] Figure 1 It is a flowchart of a positioning method for a GOIP remote control end provided in an embodiment of the present invention. The embodiment of the present invention is applicable to the situation of detecting the location of the GOIP remote control end by using signaling call detail record data and domain name Internet access log data; this method can be executed by a positioning device of the GOIP remote control end, and this device can be composed of hardware and / or software and is generally integrated in an electronic device. Typically, it can be integrated in a computer device or a server. As Figure 1 shown, the method specifically includes the following steps:

[0029] S110. Obtain signaling call detail record data for a preset time period, and obtain at least one abnormal base station identifier and the base station longitude and latitude information corresponding to each abnormal base station identifier according to the signaling call detail record data and a preset abnormal base station screening condition.

[0030] Among them, the preset time period can be a preset time length. For example, the preset time period can be one day, one week or one month. The signaling call detail record data can be relevant data generated by each calling number during a call. For example, the local number, the opposite number, the call start time, the call duration, the base station identifier corresponding to the call, the LAC (Location Area Code) where the call is located, and the CI (Cell Identity) where the call is located, etc.

[0031] In this embodiment, first, based on the signaling call detail record data of a preset time period, numbers that meet the preset abnormal number conditions can be screened out. For example, numbers with a fixed LAC and CI where the call is located and the number of calls on the same day exceeding a certain quantity; or numbers with the number of calls on the same day exceeding a certain quantity and the regional distribution of the counterpart numbers being very scattered. Then, based on the screened numbers and the preset abnormal base station screening conditions, the abnormal base station identifier can be determined, that is, the base station identifier where the GOIP device may be located. At the same time, in the signaling call detail record data, the LAC where the call corresponding to the abnormal base station identifier is located and the CI data of the call location can be obtained, and based on this LAC and CI data, the longitude and latitude information of the base station corresponding to the abnormal base station identifier can be obtained. Thus, the accurate positioning of the GOIP device can be achieved.

[0032] Among them, the preset abnormal base station screening conditions can be conditions for determining an abnormal base station according to abnormal numbers set in advance. For example, the preset base station screening conditions can be that within the same time period, there are more than a certain quantity (for example, 100) of abnormal numbers making calls under a base station.

[0033] S120. Obtain the domain name Internet access log data of a preset time period, and obtain at least one accessed domain name and the Internet Protocol (IP) access chain corresponding to each accessed domain name in the domain name Internet access log data.

[0034] Among them, the domain name Internet access log data can include the domain name access data of the Internet access device. For example, the domain name Internet access log data can include contents such as device IMEI, device Internet Protocol (IP), accessed domain name, access chain, log generation time, etc.

[0035] In this embodiment, the accessed domain name each time the user accesses the Internet and the IP access chain corresponding to the accessed domain name can be obtained from the domain name Internet access log data. Among them, the IP access chain can include the local IP address initiating the network access and the remote IP address of the accessed software or web page.

[0036] S130. When it is detected that the target accessed domain name successfully matches at least one domain name in the preset domain name library, according to the IP access chain corresponding to the target accessed domain name, obtain the target local IP address and at least one remote IP address corresponding to the target accessed domain name.

[0037] Among them, the preset domain name database can be a set of domain names of remotely controlled software (for example, Sunlogin remote control software) set in advance.

[0038] It should be noted that due to the characteristics of the GOIP device itself, that is, by pre-establishing a SIP (Session Initiation Protocol) server and the GOIP device, an operator can connect to the GOIP device through the network to achieve remote calls with the separation of the person and the card. During this process, the users of the GOIP device usually log in to the remote control software at the remote control end and control the GOIP device to make calls, answer calls and other actions through the remote control software.

[0039] Therefore, by pre-obtaining the domain name of the remote control software to construct a preset domain name library, and comparing each accessed domain name in the domain name access log data with each domain name in the preset domain name library, the device IP with the access behavior of the remote control software can be obtained. Then, multiple IP access chains corresponding to the device IP can be obtained from the domain name access log data. Furthermore, by splitting each IP access chain, the corresponding target local IP address and multiple remote IP addresses can be obtained.

[0040] Optionally, obtaining the target local IP address and at least one remote IP address corresponding to the target accessed domain name according to the IP access chain corresponding to the target accessed domain name may include: using a preset character to split the IP access chain corresponding to the target accessed domain name to obtain the target local IP address and at least one remote IP address corresponding to the target accessed domain name.

[0041] Among them, the preset character may be the "-" character. It should be noted that in the IP access chain field data, the starting IP address and the accessed IP address are connected by the "-" character. Therefore, the IP access chain field can be split by the "-" character to obtain the local IP address and the remote IP address.

[0042] S140. Obtain the longitude and latitude information corresponding to each of the remote IP addresses, and when it is detected that the longitude and latitude information corresponding to the target remote IP address satisfies the preset similarity detection condition with the base station longitude and latitude information corresponding to at least one abnormal base station identifier, determine the location of the GOIP remote control end of the Global System for Mobile Communications (GSM) according to the target local IP address.

[0043] Among them, the preset similarity detection condition may be a condition preset for determining whether two longitude and latitude information are similar. For example, the preset similarity detection condition may be that both the longitude difference and the latitude difference are less than a preset difference.

[0044] In this embodiment, the remote IP addresses corresponding to the target local IP address can be resolved to obtain the longitude and latitude information corresponding to each remote IP address. Then, it can be respectively determined whether the longitude and latitude information corresponding to each remote IP address satisfies a preset similarity detection condition with the base station longitude and latitude information corresponding to each abnormal base station identifier. If it is detected that the longitude and latitude information corresponding to a remote IP address satisfies the preset similarity detection condition with the base station longitude and latitude information corresponding to one or more abnormal base station identifiers, the target local IP address corresponding to the remote IP address can be resolved to obtain the longitude and latitude information corresponding to the target local IP address, that is, the location information of the GOIP remote control end.

[0045] In this embodiment, by detecting the GOIP remote control end based on the two dimensions of traffic behavior and Internet access behavior, accurate detection of the GOIP remote control end can be achieved; in addition, based on the domain name Internet access log data, accurate positioning of the GOIP remote control end can be realized, so as to assist in effectively combating the GOIP users and improving communication security.

[0046] In an alternative implementation manner of this embodiment, detecting that the longitude and latitude information corresponding to the target remote IP address satisfies the preset similarity detection condition with the base station longitude and latitude information corresponding to at least one abnormal base station identifier may include: calculating the position similarity between the longitude and latitude information corresponding to the target remote IP address and the base station longitude and latitude information corresponding to each of the abnormal base station identifiers through a preset similarity calculation method; if it is detected that the position similarity between the longitude and latitude information corresponding to the target remote IP address and the base station longitude and latitude information corresponding to at least one abnormal base station identifier is greater than a preset position similarity threshold, it is determined that the longitude and latitude information corresponding to the target remote IP address satisfies the preset similarity detection condition with the base station longitude and latitude information corresponding to at least one abnormal base station identifier.

[0047] Among them, the preset similarity calculation method may be the Pearson correlation coefficient method. Specifically, for the longitude and latitude information X corresponding to the target remote IP address and the base station longitude and latitude information Y corresponding to an abnormal base station identifier, the correlation coefficient between the two can be represented by dividing the covariance cov(X,Y) of the two by the product of their respective standard deviations (σX,σY). For the Pearson correlation coefficient method, the closer the correlation coefficient is to 1 or -1, the stronger the correlation between the two; the closer the correlation coefficient is to 0, the weaker the correlation between the two.

[0048] In this embodiment, after calculating the location similarity between the longitude and latitude information corresponding to the target remote IP address and the longitude and latitude information of the base station corresponding to each abnormal base station identifier, if it is determined that the location similarity between the longitude and latitude information of the base station corresponding to one or more abnormal base station identifiers and the longitude and latitude information corresponding to the target remote IP address is greater than a preset location similarity threshold (for example, 0.8), it can be determined that the preset similarity detection condition is satisfied.

[0049] In another alternative implementation manner of this embodiment, determining the location of the global mobile Internet protocol system GOIP remote control end according to the target local IP address may include: obtaining the log-on time and log-off time corresponding to the target local IP address in the partial domain name Internet access log data corresponding to the target local IP address; obtaining the daily Internet access time interval corresponding to the target local IP address according to the log-on time and log-off time corresponding to the target local IP address;

[0050] If it is detected that the daily Internet access time interval corresponding to the target local IP address is within a preset working period and the corresponding daily Internet access duration is greater than a preset duration threshold, then obtain the number of remote IP addresses corresponding to the target local IP address; if it is detected that the number of remote IP addresses corresponding to the target local IP address is greater than a preset IP address number threshold, then determine the target local IP address as the IP address of the GOIP remote control end, and resolve the IP address of the GOIP remote control end to obtain the longitude and latitude information of the GOIP remote control end.

[0051] In this embodiment, after determining that the preset similarity detection condition is satisfied between the longitude and latitude information corresponding to the target remote IP address and the longitude and latitude information of the base station corresponding to at least one abnormal base station identifier, it is also possible to further determine the target local IP address to determine whether it is the IP address corresponding to the GOIP remote control end.

[0052] Specifically, the log-on time and log-off time corresponding to the target local IP address can be obtained in the partial domain name Internet access log data corresponding to the target local IP address; then, the log-on time and log-off time can be aggregated by day to obtain the daily Internet access time interval.

[0053] Then, it is determined whether the daily Internet access time interval corresponding to the target local IP address is within the preset working period, and whether the daily Internet access duration corresponding to the daily Internet access time interval is greater than the preset duration threshold. It should be noted that since GOIP users usually operate during the working period, therefore, based on the daily Internet access time interval corresponding to the target local IP address, it can be determined whether it is the IP address corresponding to the GOIP remote control end. For example, if the daily Internet access time interval corresponding to the target local IP address is 9:00 - 17:00, the preset working period is 8:30 - 17:30, and the preset duration threshold is 6 hours, then this daily Internet access time interval is both within the preset working period and the corresponding daily Internet access duration is greater than the preset duration threshold. Therefore, the number of remote IP addresses corresponding to this target local IP address can be obtained for further judgment.

[0054] It should be noted that since GOIP users usually remotely control multiple GOIP devices, therefore, based on the number of remote IP addresses corresponding to the target local IP address, it can be further determined whether the target local IP address is the IP address corresponding to the GOIP remote control end. Specifically, after obtaining the number of remote IP addresses corresponding to the target local IP address, if it is determined that the number of remote IP addresses corresponding to the target local IP address is greater than the preset IP address number threshold, it means that the number of controlled devices controlled by the remote control end corresponding to the target local IP address is abnormal. At this time, it can be finally determined that the target local IP address is the IP address corresponding to the GOIP remote control end.

[0055] Through the above settings, the probability of misjudging the GOIP remote control end can be reduced, and the positioning accuracy of the location of the GOIP remote control end can be improved.

[0056] In another optional implementation manner of this embodiment, after parsing the IP address of the GOIP remote control end to obtain the longitude and latitude information of the GOIP remote control end, it may further include: obtaining the abnormal International Mobile Equipment Identity (IMEI) codes matched by each remote IP address corresponding to the IP address of the GOIP remote control end, and the local numbers and call location information matched by each of the abnormal IMEI codes; outputting and displaying each of the abnormal IMEI codes, the local numbers and call location information matched by each of the abnormal IMEI codes, and the longitude and latitude information of the GOIP remote control end.

[0057] In this embodiment, after determining the longitude and latitude information of the GOIP remote control end, it is also possible to obtain the abnormal International Mobile Equipment Identity (IMEI) codes corresponding to the respective remote IP addresses, the local numbers corresponding to the respective abnormal IMEIs, and the call location information from the partial domain name Internet access log data corresponding to the IP address of the GOIP remote control end, and output and display the information obtained above.

[0058] The technical solution provided by the embodiment of the present invention is based on signaling call detail record data for a preset time period and preset abnormal base station screening conditions to obtain multiple abnormal base station identifiers and corresponding base station longitude and latitude information; obtain domain name Internet access log data for a preset time period, and obtain at least one accessed domain name and the Internet Protocol (IP) access chain corresponding to each accessed domain name in the domain name Internet access log data; when it is detected that the target accessed domain name successfully matches at least one domain name in the preset domain name library, obtain the corresponding target local IP address and at least one remote IP address according to the IP access chain corresponding to the target accessed domain name; obtain the longitude and latitude information corresponding to each remote IP address, and when it is detected that the longitude and latitude information corresponding to the target remote IP address satisfies the preset similarity detection condition with the base station longitude and latitude information corresponding to at least one abnormal base station identifier, determine the location of the Global System for Mobile Communications Internet Protocol (GOIP) remote control end according to the target local IP address. By combining signaling call detail record data and domain name Internet access log data to detect the location of the GOIP remote control end, it is possible to accurately locate the GOIP device while accurately locating the GOIP remote control end.

[0059] Figure 2A FIG. is a flowchart of a method for locating a GOIP remote control end provided in another embodiment of the present invention. This embodiment further refines the above technical solution, and the technical solution in this embodiment can be combined with one or more of the above embodiments. Specifically, referring to Figure 2A , the method specifically includes the following steps:

[0060] S210. Obtain signaling call detail record data for a preset time period, and screen at least one abnormal number from each of the local numbers according to a preset abnormal number screening condition.

[0061] Among them, the signaling call detail record data may include the local number, call start time, call duration, and call location information; the call location information may include the Location Area Code (LAC) where the call is located and the Cell Identity (CI) where the call is located. The preset abnormal number screening condition may be a condition preset for determining whether a telephone number is an abnormal number; for example, the daily call frequency is greater than 100, or the call location information remains unchanged for a period of time. In this embodiment, the numbers that meet the conditions can be screened from the signaling call detail record data according to the preset abnormal number screening condition as abnormal numbers.

[0062] In an alternative implementation of this embodiment, screening at least one abnormal number from each of the local numbers according to a preset abnormal number screening condition may include:

[0063] During a first preset time period, if the number of different call location information corresponding to a certain local number is detected to be less than a preset number threshold, then the detected local number is determined as a first candidate abnormal number; during the first preset time period, if the call frequency corresponding to a certain first candidate abnormal number and the same call location information is detected to be greater than a preset frequency threshold, then the detected first candidate abnormal number is determined as a second candidate abnormal number;

[0064] During the first preset time period, if it is detected that the number type of the counterpart number corresponding to a certain second candidate abnormal number is a mobile phone number and the dispersion degree of the corresponding counterpart number is greater than a preset dispersion threshold, then the detected second candidate abnormal number is determined as a third candidate abnormal number; within a preset time period, if the number of counterpart numbers whose call times with a certain third candidate abnormal number are greater than a preset call times threshold is detected to be less than a preset number threshold, then the detected third candidate abnormal number is determined as an abnormal number.

[0065] Among them, the signaling call record data may further include the counterpart number. The first preset time period may be a time interval within a preset time period; for example, if the preset time period is one week, then the first preset time period may be one day.

[0066] In this embodiment, when screening abnormal numbers, the number of different call location information of each local number within the first preset time period may be counted first. If it is detected that the number corresponding to a certain local number is less than the preset number threshold, it means that the call location of this local number is basically fixed. At this time, this local number can be determined as a first candidate abnormal number. Then, for each of the screened first candidate abnormal numbers, it is further determined whether the call frequency under the same call location information within the first preset time period is greater than the preset frequency threshold. If so, this first candidate abnormal number can be determined as a second candidate abnormal number.

[0067] Further, for each of the selected second candidate abnormal numbers, the number type of its corresponding peer number and the dispersion degree of the peer number can be obtained, and it is determined whether the number type of the peer number is a mobile phone number, and whether the dispersion degree of the peer number is greater than a preset dispersion degree threshold. If it is determined that a certain second candidate abnormal number satisfies both of the above two conditions, then this second candidate abnormal number can be determined as a third candidate abnormal number. Finally, for each of the selected third candidate abnormal numbers, within a preset time period, first count the number of peer numbers whose call times with the same peer number are greater than a preset call time threshold, and then when it is detected that the number of peer numbers satisfying this condition is greater than a preset number threshold, then this third candidate abnormal number can be determined as an abnormal number.

[0068] The advantages of the above settings are as follows: the probability of misidentifying abnormal numbers can be reduced, and the detection accuracy of abnormal numbers can be improved.

[0069] S220. According to the call start time and call duration corresponding to each of the abnormal numbers, determine at least one abnormal base station identifier from the base station identifiers corresponding to the call location information of each of the abnormal numbers.

[0070] In this embodiment, according to the call start time and call duration corresponding to each abnormal number, the call time interval corresponding to each abnormal number can be obtained. When it is detected that within the same call time interval, there are multiple abnormal numbers making calls under the base station corresponding to the same base station identifier, then this base station identifier can be determined as an abnormal base station identifier.

[0071] In another alternative embodiment of this embodiment, determining at least one abnormal base station identifier from the base station identifiers corresponding to the call location information of each of the abnormal numbers according to the call start time and call duration corresponding to each of the abnormal numbers may include: according to the call start time and call duration corresponding to each of the abnormal numbers, obtain the call time period corresponding to each of the abnormal numbers, and determine the base station identifier corresponding to the call location information of each of the abnormal numbers as a candidate base station identifier; within a second preset time period, if according to the call time periods corresponding to each of the abnormal numbers, it is detected that the number of abnormal numbers corresponding to a certain candidate base station identifier is greater than a preset abnormal number threshold, then the detected candidate base station identifier is determined as an abnormal base station identifier.

[0072] Among them, the call time period corresponding to the abnormal number may include the call start time and call end time corresponding to the abnormal number. The second preset time period may be a time interval within a preset time period, for example, one hour.

[0073] In this embodiment, when the number of abnormal numbers corresponding to a certain candidate base station identifier is detected to be greater than the preset abnormal number threshold within the second preset time period, that is, there are multiple abnormal numbers making calls under the base station corresponding to the same base station identifier within the same time period, the detected candidate base station identifier can be determined as an abnormal base station identifier.

[0074] S230. Analyze the call location information corresponding to each of the abnormal base station identifiers to obtain the longitude and latitude information of the base stations corresponding to each of the abnormal base station identifiers.

[0075] In this embodiment, after obtaining the abnormal base station identifier, the longitude and latitude information of the base station corresponding to the abnormal base station identifier can be determined according to the call location area code (LAC) and call identity (CI) in the call location information corresponding to the abnormal base station identifier. Among them, based on the LAC and CI, the accurate determination of the uniquely corresponding base station can be realized, and then according to the base station deployment information, the longitude and latitude information corresponding to the base station can be obtained.

[0076] S240. Obtain the domain name Internet access log data for a preset time period, and obtain at least one accessed domain name and the Internet protocol (IP) access chain corresponding to each accessed domain name from the domain name Internet access log data.

[0077] S250. When it is detected that the target accessed domain name successfully matches at least one domain name in the preset domain name library, obtain the target local IP address and at least one remote IP address corresponding to the target accessed domain name according to the IP access chain corresponding to the target accessed domain name.

[0078] S260. Obtain the longitude and latitude information corresponding to each of the remote IP addresses, and when it is detected that the longitude and latitude information corresponding to the target remote IP address satisfies the preset similarity detection condition with the longitude and latitude information of the base stations corresponding to at least one abnormal base station identifier, determine the location of the global system for mobile communications Internet protocol (GSM IP) remote control end according to the target local IP address.

[0079] The technical solution provided by the embodiment of the present invention screens at least one abnormal number from each local number according to the preset abnormal number screening conditions; and determines at least one abnormal base station identifier among the base station identifiers corresponding to the call location information of each abnormal number according to the call start time and call duration corresponding to each abnormal number; further analyzes the call location information corresponding to each abnormal base station identifier to obtain the longitude and latitude information of the base stations corresponding to each abnormal base station identifier; by detecting and positioning the GOIP device based on the call behavior, the accurate detection and positioning of the GOIP device can be realized; in addition, by detecting and positioning the GOIP remote control end from two dimensions of call behavior and Internet access behavior, the accurate and efficient detection and positioning of the GOIP remote control end can be realized.

[0080] In a specific implementation manner of this embodiment, the process of the positioning method for the GOIP remote control end can be as Figure 2B shown. Specifically, first, signaling call detail record data is obtained, and abnormal numbers are screened based on preset abnormal number screening conditions; then, based on the screened abnormal numbers and preset abnormal base station screening conditions, research and judgment of abnormal base stations are carried out to obtain abnormal base station identifiers and the longitude and latitude information of the base stations corresponding to the abnormal base station identifiers.

[0081] At the same time, domain name Internet access log data is obtained, and the device IP addresses of the domains accessing the remote control software are screened from the domain name Internet access log data; then, the IP access chains corresponding to the screened device IP addresses are obtained, and each obtained IP access chain is segmented to obtain the remote IP addresses.

[0082] Then, position information correlation judgment is carried out on the longitude and latitude information of the base stations corresponding to each abnormal base station identifier and the longitude and latitude information corresponding to each remote IP address, and the positions of the GOIP device and the GOIP remote control end are output according to the correlation judgment result. Specifically, if it is detected that the longitude and latitude information corresponding to a certain remote IP address satisfies the preset similarity detection condition with the longitude and latitude information of the base stations corresponding to at least one abnormal base station identifier, the longitude and latitude information corresponding to the detected remote IP address can be determined as the position information of the GOIP device, and the local IP address corresponding to the detected remote IP address can be obtained, and the longitude and latitude information corresponding to the local IP address can be determined as the position information of the GOIP remote control end.
