detailed description

In order to better understand the above technical solutions, the technical solutions of the embodiments of the present specification will be described in detail through the accompanying drawings and specific embodiments. It should be understood that the embodiments of the present specification and the specific features in the embodiments are the technical solutions of the embodiments of the present specification. The detailed description is not a limitation on the technical solutions of the present specification. In the case of no conflict, the embodiments of the present specification and the technical features in the embodiments can be combined with each other.

Please refer to FIG. 1, which is a schematic diagram of an application scenario of Internet transaction positioning according to an embodiment of the present specification. The transaction terminal 100 is located on the user side and communicates with the server 200 on the network side. The transaction processing client 101 in the transaction terminal 100 may be an APP or website that implements services based on the Internet, provides a transaction operation interface for users, and provides transaction information of Internet transactions to the network side for processing; the Internet in the server 200 The transaction positioning device 201 is configured to locate an Internet transaction involved in the transaction processing client 101.

The transaction terminal 100 may be a smart terminal such as a smart phone, a notebook computer, a tablet computer, and an all-in-one computer. For Internet transactions completed on a transaction terminal with a positioning function such as a smart phone or tablet and the positioning function is turned on, the trading area of the Internet transaction can be obtained through satellite positioning signals received by the smart phone or tablet. The embodiments of the present specification perform positioning for Internet transactions completed on a transaction terminal such as a notebook or an all-in-one without a positioning function, or on a transaction terminal such as a smart phone or a tablet that has a positioning function but the positioning function is turned off.

In a first aspect, an embodiment of the present specification provides a method for positioning an Internet transaction. FIG. 2 is a flowchart of the Internet transaction positioning method, and the Internet transaction positioning method includes steps S201 to S203.

S201. Extract the IP address of the terminal to be located from the transaction information of the transaction to be located. The terminal to be located is a transaction terminal that performs the transaction to be located.

For each Internet transaction, the transaction terminal that conducts the Internet transaction will generate corresponding transaction information and provide the transaction information to the network side for processing. The transaction information includes, but is not limited to, the time of the transaction, the amount of the transaction, Store information for transactions, the IP address of the transaction terminal, satellite positioning signals received by the transaction terminal, the identity of the transaction terminal, the base station information connected to the transaction terminal, and the WIFI information connected to the transaction terminal.

It should be noted that, for Internet transactions in different transaction scenarios, the corresponding transaction information is also different. For example, for the aforementioned Internet transactions completed on a transaction terminal that does not have a positioning function, such as a notebook or an all-in-one, or on a transaction terminal that has a positioning function but has a positioning function turned off, such as a smart phone or tablet, the corresponding transaction information does not include Satellite positioning signals received by transaction terminals; For Internet transactions in small shops, the corresponding transaction information does not include the store information for the transaction; For Internet transactions using GPRS networking, the corresponding transaction information does not include the transaction WIFI information connected to the terminal; for Internet transactions using WIFI networking, the corresponding transaction information does not include the base station information connected to the transaction terminal.

However, Internet transactions must be conducted in a networked state, and transaction terminals that conduct Internet transactions have unique identifications. Therefore, the transaction information of each Internet transaction includes the IP address of the transaction terminal and the identity of the transaction terminal. In the embodiment of the present specification, the IP address of the transaction terminal that performs the transaction to be located is extracted from the transaction information of the transaction to be located, and the transaction to be located is performed according to the IP address of the transaction terminal that is to be located. Positioning. For ease of description, a transaction terminal that performs the transaction to be located is defined as the terminal to be located.

S202. Determine whether the IP address of the terminal to be located belongs to a stable IP address segment, where the stable IP address segment is an IP distributed in a fixed area determined according to multiple first Internet transactions within a first preset historical time period. An address segment, and the stable IP address segment is an address segment corresponding to the first M bits of the IP address of the transaction terminal involved in the plurality of first Internet transactions, where M is a positive integer.

All IP addresses will be initially allocated according to administrative regions such as provinces, municipal cities, county cities or districts, and each province, municipal city, county city or district will be the area where each IP address is distributed. However, after the initial allocation of all IP addresses, the allocation scheme may not be strictly enforced due to various reasons, and there are dynamic changes in some IP address distribution areas. Therefore, the accuracy of the existing positioning results through GeoIP not tall.

A large number of Internet transactions have occurred before the transaction to be located. Most of the transaction information of the Internet transactions that have occurred include the store information of the transaction, the satellite positioning signals received by the transaction terminal, the base station information connected to the transaction terminal, or the transaction terminal. Positioning information such as connected WIFI information that can be accurately located. The IP address distribution obtained based on these positioning information is more accurate than positioning through GeoIP. Therefore, the embodiment of the present specification determines the stable IP address segment and the fixed area where the stable IP address segment is distributed according to the multiple first Internet transactions.

FIG. 3 is a flowchart of determining a fixed area of the stable IP address segment distribution according to an embodiment of the present specification. The determining of the fixed area of the stable IP address segment distribution includes steps S301 to S305.

S301. Extract the Dolby first Internet transaction from all Internet transactions in the first preset historical time period, and the transaction information of the first Internet transaction includes an IP of a transaction terminal that performs the first Internet transaction. An address and a satellite positioning signal received by a transaction terminal conducting the first Internet transaction.

The first preset historical time period can be divided as follows: since the time attribute is a continuous value, time can be discretized, that is, the time is segmented. For example, the first preset historical time period is segmented according to natural days. Is a certain day or a certain day; if segmented according to the natural month, the first preset historical time period is a certain month or a certain number of months. The longer the first preset historical time period is set, the larger the total amount of the first Internet transaction extracted, and the more accurately the fixed area of the stable IP address segment distribution determined according to the multiple first Internet transactions is. However, the data processing speed becomes slower accordingly, and the length of the first preset historical time period may be specifically set according to actual requirements.

In an optional implementation manner, the first preset historical time period is a historical time period corresponding to the first preset historical time and the time when the transaction to be located is performed, and the first preset historical time is Any time before the time when the transaction to be located is performed. By setting the first preset historical time period to a historical time period corresponding to the time from the first preset historical time to the time when the transaction to be located is performed, the plurality of first Internet transactions obtained are latest That is, the fixed area of the stable IP address segment distribution is determined according to the latest Internet transaction that has occurred. It is equivalent to update the fixed area of the first stable IP address segment distribution each time an Internet transaction is located, so that the IP address distribution can be updated in real time, which further improves the accuracy of positioning the transaction to be located.

The selection of the first Internet transaction may be the Internet where the transaction information includes the store information of the transaction, the satellite positioning signal received by the transaction terminal, the base station information connected by the transaction terminal, or the WIFI information connected by the transaction terminal, which can perform accurate positioning. transaction. Considering that the satellite positioning signals are the most abundant in the transaction information of all Internet transactions, the transaction information of the first Internet transaction extracted in the embodiments of this specification includes the IP address of the transaction terminal that conducted the first Internet transaction and the first Internet transaction Satellite positioning signals received by transaction terminals for Internet transactions. Further, the satellite positioning signal may be a GPS signal, a GLONASS signal, a GALILEO signal, or a Beidou satellite signal.

Considering the inconsistency between the transaction area and the satellite positioning location, the transaction information of the first Internet transaction may further include a transaction time and a positioning time, and the absolute value of the difference between the transaction time and the positioning time is less than a preset time difference The transaction time is a time when the first Internet transaction is performed, and the positioning time is a time when a transaction terminal that performs the first Internet transaction receives a satellite positioning signal. By setting the absolute value of the difference between the transaction time and the positioning time to be smaller than the preset time difference, it is possible to filter out Internet transactions where the transaction area and the satellite positioning location are inconsistent, and further improve the positioning of the transaction to be located. accuracy. The preset time difference may be set according to actual experience, which is not limited in the embodiment of the present specification.

S302. Obtain a unique area of the IP address distribution of the transaction terminal that performs each first Internet transaction according to the satellite positioning signal received by the transaction terminal that performs each first Internet transaction.

After extracting the plurality of first Internet transactions, according to the satellite positioning principle and the satellite positioning signal received by the transaction terminal that conducts each first Internet transaction, the transaction area where each of the first Internet transactions is performed will be obtained. The transaction area of each first Internet transaction is described as the only area in which the IP addresses of the transaction terminals performing each first Internet transaction are distributed.

S303. According to the unique area of the IP address distribution of the transaction terminal where each first Internet transaction is performed, obtain each area of each IP address segment to be determined and the proportion of each area. The IP address segment to be determined is An address segment corresponding to the first M bits of the IP address of the transaction terminal of each first Internet transaction.

The value of M can be set according to factors such as the administrative level of the area to be positioned, the accuracy of the positioning, and the coverage of the positioning. The embodiment of the present specification takes as an example the positioning of the city-level city of the transaction to be located. When the value of M is 24, the positioning accuracy and coverage obtained are relatively high. Of course, in other embodiments, if a higher-level administrative region such as a province to which the transaction to be located is located, the value of M may be smaller; if a county-level urban area to which the transaction to be located is located is lower, etc. Level administrative area, the value of M can be larger.

After the value of M is determined, the first M bits of the IP address of the transaction terminal for each first Internet transaction are obtained, and the same first M bits correspond to an IP address segment to be determined. According to the unique area of the IP address distribution of the transaction terminal performing each first Internet transaction, each area of each IP address segment distribution to be determined and the proportion of each area are calculated.

Taking the value of M as 24 and extracting five first Internet transactions from the first preset historical time period as an example, if the IP addresses of the transaction terminals corresponding to the five first Internet transactions are 223.85.221.198, 223.85.221.101, 223.85.221.20, 223.85.221.30, and 182.132.23.97. The only areas where the aforementioned five IP addresses are distributed are Chengdu, Chengdu, Chengdu, Mianyang, and Deyang. The IP address segment to be determined is 223.85 .221 and the IP address segment to be determined is 182.132.23. The IP address segment to be judged 223.85.221 is distributed in Chengdu and Mianyang, and Chengdu accounts for 75% and Mianyang City accounts for 25%; the IP address segment to be judged 182.132.23 is distributed in Deyang, And Deyang City accounts for 100%.

S304: Determine whether the highest proportion of the proportions of the regions corresponding to the IP address segment to be judged is greater than the first preset percentage.

After obtaining the proportion of each region corresponding to the IP address segment to be determined, the highest proportion of the proportion of each region is compared with the first preset percentage. If an IP address segment to be judged does not change after the initial allocation, ideally there is only one distribution area, and the corresponding maximum ratio is 100%. Considering the data collection error, the IP address of the transaction terminal that conducts the first Internet transaction may be a roaming IP address or a proxy IP address, etc., in the embodiment of this specification, when the maximum ratio is greater than the first preset percentage , Determining the IP address segment to be determined as the stable IP address segment. The first preset percentage may be set according to actual conditions such as a data collection error, a roaming IP address, or a proxy IP address, which is not limited in the embodiments of this specification.

If the highest percentage is greater than the first preset percentage, step S305 is executed to determine that the IP address segment to be determined is the stable IP address segment, and the area corresponding to the highest percentage is determined to be the A fixed area where stable IP address segments are distributed.

Taking the first preset percentage as 70% as an example, the highest proportion 75% corresponding to the IP address segment 223.85.221 to be determined is greater than the first preset percentage 70%, so the IP address segment to be determined 223.85.221 is the stable IP address segment, and the region corresponding to the highest proportion of 75% is Chengdu, which is a fixed area where the stable IP address segment 223.85.221 is distributed; the IP address segment to be determined corresponds to 182.132.23. The highest percentage is 100% greater than the first preset percentage of 70%, so the IP address segment to be determined 182.132.23 is the stable IP address segment, and the area corresponding to the highest percentage 100% is Deyang. A fixed area with a stable IP address segment 182.132.23.

After determining the stable IP address segment, the IP address of the terminal to be located is compared with each stable IP address segment to determine whether the IP address of the terminal to be located belongs to a stable IP address segment, that is, the pending Whether the first M bits of the IP address of the bit terminal are the same as the stable IP address segment. Still taking the aforementioned stable IP address segment 223.85.221 and the stable IP address segment 182.132.23 as examples, if the IP address of the terminal to be located is 223.85.221.35, the IP address of the terminal to be located is 223.85. 221.35 belongs to the stable IP address segment 223.85.221.

If the IP address of the terminal to be located belongs to the stable IP address segment, step S203 is executed to determine a fixed area where the stable IP address segment is distributed as a transaction area where the to-be-positioned transaction is performed.

The stable IP address segment is distributed in the fixed area, which indicates that all IP addresses included in the stable IP address segment are distributed in the fixed area. Therefore, if the IP address of the terminal to be located belongs to the stable IP address segment, the IP address of the terminal to be located is also distributed in the fixed area, that is, the fixed area is a transaction for performing the transaction to be located. region.

In the embodiment of the present specification, since the stable IP address segment is an IP address segment distributed in the fixed area determined according to the multiple first Internet transactions, the transaction area where the first Internet transaction is performed is usually based on satellites. Positioning signals, store information for transactions, or base station information connected to transaction terminals are obtained. When the area of an IP address distribution dynamically changes relative to the initial allocation, the dynamic change is through satellite positioning signals, store information for transactions, or transaction terminals. The information of the connected base stations can be reflected in the multiple first Internet transactions. Therefore, the IP address distribution determined according to the multiple first Internet transactions is more accurate than the initial allocation. The fixed area is determined as the transaction area where the transaction to be located is more accurate, and the accuracy of positioning the transaction to be located is improved.

As mentioned earlier, the transaction information of Internet transactions includes, but is not limited to, the time of the transaction, the amount of the transaction, the store information of the transaction, the IP address of the transaction terminal, the satellite positioning signal received by the transaction terminal, the identity of the transaction terminal, Information about the base station connected to the transaction terminal and WIFI information connected to the transaction terminal, etc., the information of the store where the transaction is performed, the IP address of the transaction terminal, the satellite positioning signal received by the transaction terminal, the identity of the transaction terminal, The base station information connected to the transaction terminal and the WIFI information connected to the transaction terminal are positioning information that can be located. Therefore, in addition to locating the to-be-positioned transaction based only on the IP address of the to-be-positioned transaction terminal, the to-be-positioned transaction may also be combined with the information of the store where the transaction is performed, the satellite positioning signal received by the The identity of the transaction terminal, the base station information connected to the transaction terminal, and the WIFI information connected to the transaction terminal locate the transaction to be located. In an optional implementation manner, the Internet transaction positioning method provided by the embodiment of the present specification further includes steps S204 and S205.

S204. Determine, according to a preset priority order of various types of positioning information, whether there is positioning information in the transaction information of the to-be-positioned transaction that has a higher priority than the IP address of the terminal to be located.

The positioning information includes at least one of information about the store where the transaction is performed, the IP address of the transaction terminal, the satellite positioning signal received by the transaction terminal, the identity of the transaction terminal, the base station information connected to the transaction terminal, and the WIFI information connected to the transaction terminal. According to the accuracy of positioning using various types of positioning information, the priority order of the various types of positioning information is set. For example, if the accuracy of locating using the information of the transaction store is higher than the accuracy of locating using the IP address of the transaction terminal, set the priority of the information of the transaction store to be higher than the IP address of the transaction terminal; The accuracy of locating the store information combined with the base station information connected to the transaction terminal is higher than the location accuracy of the store information used for the transaction. The priority of the store information combined with the base station information connected with the transaction terminal is set to Higher than the information of the store where the transaction took place.

If there is no positioning information in the transaction information of the to-be-positioned transaction that has a higher priority than the IP address of the terminal to be located, step S201 is executed to extract the terminal-to-be-positioned from the transaction information of the to-be-positioned transaction. IP address; otherwise, execute step S205, extract the highest priority positioning information from the transaction information of the transaction to be positioned, and determine the transaction area where the transaction to be positioned is performed according to the highest priority positioning information.

Positioning the to-be-positioned transaction according to the IP address of the transaction terminal of the to-be-positioned transaction, refer to the foregoing steps S201 to S203, and determine the transaction area where the to-be-positioned transaction is performed according to the highest priority positioning information, depending on the priority Depending on the highest level of positioning information. For example, if the positioning information with the highest priority is information of a store where a transaction is performed, determining the location of the store where the transaction to be located is a transaction area where the transaction to be located is performed; If the positioning information is information of the base station connected to the transaction terminal, the position of the base station connected to the transaction terminal that performs the transaction to be located is determined as the transaction area where the transaction to be located is performed; if the positioning information with the highest priority is a transaction The WIFI information connected to the terminal determines the WIFI position connected to the transaction terminal that performs the transaction to be located as the transaction area where the transaction to be located is performed.

In the foregoing embodiments of the present specification, the IP address of the terminal to be located may not belong to any stable IP address segment. In view of this situation, the embodiments of the present specification locate the transaction to be located in combination with the last transaction area of the terminal to be located. In an optional implementation manner, the Internet transaction positioning method provided by the embodiment of the present specification further includes steps S206 to S208.

If the IP address of the terminal to be located does not belong to the stable IP address segment, step S206 is performed to determine whether the IP address of the terminal to be located belongs to an unstable IP address segment, where the unstable IP address segment is The IP address segments distributed in more than two areas determined according to the multiple first Internet transactions, and the unstable IP address segments correspond to the first M bits of the IP addresses of the transaction terminals involved in the multiple first Internet transactions Address segment.

For a specific determination manner of the unstable IP address segment, refer to FIG. 3. If the maximum ratio is not greater than the first preset percentage, step S306 is performed to determine that the IP address segment to be determined is the unstable IP address. An address segment, and determine an area that satisfies a preset condition among the regions of the distribution of the IP address segments to be determined as two or more regions of the unstable IP address segment distribution.

The preset condition includes that the proportion is higher than the second preset percentage and / or the area corresponding to the highest proportion belongs to the same higher administrative area, and the second preset percentage is smaller than the first preset percentage. Taking the first preset percentage as 90% as an example, the highest percentage 75% corresponding to the IP address segment 223.85.221 is less than the first preset percentage 90%, so the IP address segment to be determined 223.85.221 is the unstable IP address segment. If the preset condition includes a proportion higher than the second preset percentage and the area corresponding to the highest percentage belongs to the same higher administrative area, the second preset percentage is 20%, because Chengdu's proportion It is 75% and Mianyang City is 25%, both of which are higher than the second preset percentage. Chengdu and Mianyang both belong to Sichuan Province. Therefore, Chengdu and Mianyang are determined as the unstable IP address segment 223.85. .221 area of distribution.

After determining the unstable IP address segment, the IP address of the terminal to be located is compared with each unstable IP address segment to determine whether the IP address of the terminal to be located belongs to an unstable IP address segment, that is, to determine Whether the first M bits of the IP address of the terminal to be located are the same as the unstable IP address segment. Still using the aforementioned unstable IP address segment 223.85.221 as an example, if the IP address of the terminal to be located is 223.85.221.35, the IP address of the terminal to be located 223.85.221.35 belongs to the unstable IP address segment 223.85. 221.

If the IP address of the terminal to be located belongs to the one unstable IP address segment, step S207 is executed to determine whether two or more areas distributed by the unstable IP address segment include the last transaction area of the terminal to be located.

FIG. 4 is a flowchart of obtaining a last transaction area of the terminal to be located according to an embodiment of the present specification. The obtaining the last transaction area of the terminal to be located includes steps S401 to S404.

S401. Extract multiple second Internet transactions from all Internet transactions in a second preset historical time period, where the second preset historical time period is from the second preset historical time to the time when the transaction to be located is performed Corresponding historical time period, the transaction information of the second Internet transaction includes an identity of a transaction terminal performing the second Internet transaction, a satellite positioning signal received by the transaction terminal performing the second Internet transaction, and performing the first Second Internet transaction time.

The second preset historical time is any time before the time when the transaction to be located is performed, and the length of the second preset historical time period can be set according to actual needs, as long as a sufficient number of the extracted Second internet transaction. Similar to the selection of the first Internet transaction, the second Internet transaction may also include transaction store information, satellite positioning signals received by the transaction terminal, base station information connected by the transaction terminal, or WIFI information connected by the transaction terminal, etc. Internet transactions that allow accurate positioning of positioning information. Considering that the satellite positioning signals are the most abundant in the transaction information of all Internet transactions, the transaction information of the second Internet transaction extracted in the embodiments of this specification includes the identity of the transaction terminal that conducted the second Internet transaction, and the second Internet transaction. The satellite positioning signal received by the transaction terminal of the Internet transaction and the time when the second Internet transaction is performed.

S402. Determine each of the second terminal based on the identity of the transaction terminal that performed each second Internet transaction, the time when each second Internet transaction was performed, and the satellite positioning signal received by the transaction terminal that performed each second Internet transaction. The last transaction area of the transaction terminal corresponding to the identity.

After extracting the plurality of second Internet transactions, according to the satellite positioning principle and the satellite positioning signal received by the transaction terminal that conducts each second Internet transaction, the transaction area where each second Internet transaction is performed will be obtained. The transaction area of each second Internet transaction is described as the only area in which the IP addresses of the transaction terminals performing each second Internet transaction are distributed. The final transaction area of each transaction terminal involved in the plurality of second Internet transactions is obtained by combining the identity of the transaction terminal performing each of the second Internet transactions and the time of performing each second Internet transaction. That is, the last transaction area corresponding to each identity involved in the multiple second Internet transactions.

S403. Extract the identity of the terminal to be located from the transaction information of the transaction to be located.

The identity of the terminal to be located is a credential that can prove the identity of the terminal to be located. Taking the smartphone to be located as an example, the identity of the terminal to be located may be the serial number of the smartphone. Extracting the identity of the terminal to be located may be performed when extracting the IP address of the terminal to be located, or may be performed after extracting the IP address of the terminal to be located, which is not limited in this embodiment of the present specification.

S404. Determine the last transaction area of the terminal to be located according to the identity of the terminal to be located and the last transaction area of the transaction terminal corresponding to each identity.

Compare the identity of the terminal to be located with all the identities involved in the multiple second internet transactions, and find the identity of the terminal to be located among all the identities involved in the multiple second internet transactions Identification to obtain the last transaction area of the terminal to be located.

Taking the IP address 223.85.221.35 of the terminal to be located as an example of the unstable IP address segment 223.85.221, it is determined whether the area where the unstable IP address segment 223.85.221 is distributed includes the last of the terminal to be located.
