Based on the hardware structure, the embodiment of the terminal equipment identification method is provided.
Due to the fact that information formats of terminal equipment manufacturers are different and the like, host name information of the terminal equipment is directly extracted at present to carry out equipment identification, identified equipment information formats are not uniform, equipment information is not visually represented, and a user cannot easily confirm the terminal equipment according to the equipment information in the identification mode of the current terminal equipment.
Based on the above problems, the terminal device identification method in the embodiment of the present invention is proposed, and the terminal device identification method in the embodiment of the present invention relies on a correct device address library, where the correct device address library includes a mapping relationship between device address information and device information, and the device information is standardized in the correct device address library according to a predetermined rule, and the standardized device information has a uniform format and an intuitive information expression manner, so that a user can quickly confirm the terminal device. Specifically, the method comprises the following steps:
referring to fig. 2, in a first embodiment of the terminal device identification method of the present invention, the terminal device identification method includes:
step S11, when receiving the terminal device identification request, acquiring device feature information of the terminal device.
The terminal device identification method in this embodiment is applied to a terminal device identification device (the type of the terminal device identification device is not limited, that is, the terminal device identification device may be a router to which the terminal device accesses, and the terminal device identification device may also be a server communicatively connected to the router).
In this embodiment, a server is taken as an example for explanation, the server receives a terminal device identification request, and a triggering manner of the terminal device identification request is not specifically limited, that is, the terminal device identification request may be actively triggered by a user, for example, the server outputs terminal device identification prompt information, and the user clicks the identification prompt information to trigger the terminal device identification request; in addition, the terminal device identification request may also be triggered automatically by the server, for example, the triggering condition for the terminal device identification request preset in the server is as follows: when the terminal equipment is accessed to the server, the server automatically triggers the terminal equipment identification request when detecting that the terminal equipment is accessed.
After receiving the terminal device identification request, the server acquires device feature information carried in the terminal device identification request, that is, the server acquires a communication message reported by the terminal device, and the server parses the communication message (such as a hypertext transfer protocol (HTTP) message) reported by the terminal device to acquire the device feature information of the terminal device.
The device characteristic information in this embodiment refers to information that can reflect the characteristics of the terminal device, and the device characteristic information may be understood as information that is entered by each device manufacturer in the process of producing the terminal device, for example, the device characteristic information includes but is not limited to: device Address information (also called a MAC Address, also called a lan Address, MAC Address information, Media Access Control Address, the device Address information is an Ethernet Address or a Physical Address, the device Address information is an Address for confirming a location of the terminal device), a host Name (Hostname) of the terminal device, user agent (user agent) information, device feature field information (also called OP60, the device feature field information is a field with identification, the device feature field information is for identifying a brand, a model, a type, etc.), DNS (DNS, Domain Name System device Domain Name) information associated with the terminal device, and the like.
It is understood that the device characteristic information refers to original device information, for example, the device characteristic information is: a1660 (equipment model); the device information is general device information subjected to standardization processing, for example, device characteristic information a1660, and the corresponding standardized device information is: apple 7 (equipment model).
Step S12, comparing the device address information in the device feature information with the pre-stored address information in the correct device address library.
A correct device address library is preset in the server, and a mapping relationship between address information and device information is prestored in the correct device address library, for example, the device address information is a456xxxx123, and the corresponding device information includes: equipment brand: millet, equipment type: ma4, device type: an intelligent air conditioner; after the identification information in the correct equipment address library is subjected to standardization processing, a user can intuitively know the equipment brand, the equipment model, the equipment type and the like of the terminal equipment; the correct device address library in the embodiment of the present invention may be stored in the cloud, or may be stored locally in the server, for example, in an extended memory of the server, the correct device address library is stored in the extended memory, or in a storage device added in the local area network, for example, the correct device address library is stored in the storage device.
The server compares the equipment address information in the equipment characteristic information with each pre-stored address information in a correct equipment address base, namely, a regular expression is arranged in the server, the server compares the equipment address information in the equipment characteristic information with each pre-stored address information in the correct equipment address base according to the regular expression to obtain target address information matched with the equipment address information, and the server obtains the equipment information corresponding to the target address information to finally determine the identification result of the terminal equipment.
Step S13, if the correct device address library has target address information matching the device address information, acquiring device information corresponding to the target address information.
If the target address information matched with the equipment address information exists in the correct equipment address library, namely the equipment address information and the equipment information of the terminal equipment are stored in the correct equipment address library, the server acquires the equipment information corresponding to the target address information in the correct equipment address library.
And step S14, outputting the device information as the identification result of the terminal device.
The server takes the equipment information as the identification result of the terminal equipment and outputs the identification result so as to facilitate the user to check. In the device identification method in this embodiment, the server only processes the device address information in the device feature information, which reduces the analysis processing amount of the device feature information to improve the efficiency of device identification, and meanwhile, compared with the prior art in which the device information is identified according to the device identifier, in this embodiment, the device information identified by the correct device address library is more accurate because the user cannot modify the device address information.
Further, referring to fig. 3, a second embodiment of the terminal device identification method of the present invention is proposed on the basis of the first embodiment of the present invention.
This embodiment is after step S12 in the first embodiment, and the difference between this embodiment and the first embodiment of the present invention is:
step S21, if the correct device address library does not have the target address information matching the device address information, comparing the device characteristic information with preset characteristic information in a preset cache library.
Step S22, if there is target feature information matching the device feature information in the preset cache library, acquiring device information corresponding to the target feature information.
And step S23, outputting the device information as the identification result of the terminal device.
In this embodiment, if target address information matching the device address information does not exist in the correct device address library, the server performs device identification through the preset cache library, and the server compares the device address information with preset feature information in the preset cache library (the preset cache library refers to a preset database for storing a mapping relationship between the device feature information and the device information).
And if the target characteristic information matched with the equipment characteristic information exists in the preset cache library, the server acquires the equipment information corresponding to the target characteristic information, and the server takes the equipment information as the identification result of the terminal equipment and outputs the identification result.
In this embodiment, when the target address information matching the device address information does not exist in the correct device address library, the server performs device identification through the preset cache library, and compared with device identification performed by using the correct device address library, the amount of information in the preset cache library is the latest device information, and the amount of information in the preset cache library is small, so that the comparison time of the device characteristic information can be reduced, and the real-time performance of device identification is improved.
It can be understood that, because the device information has a plurality of types, the server may set different types of cache libraries to realize fast query of the device information, for example, the preset cache library in this embodiment includes a preset device information cache library and a device identifier cache library; the server carries out the step of equipment information identification through a preset equipment information cache library and an equipment identification cache library, and the method comprises the following steps:
a1, if the correct device address library does not have the target address information matched with the device address information, comparing the device characteristic information with the preset characteristic information in the device information cache library;
a2, if target characteristic information matched with the device characteristic information exists in the device information cache library, acquiring device information corresponding to the target characteristic information, and outputting the device information as an identification result of the terminal device;
a3, if there is no target characteristic information matching with the device characteristic information in the device information cache library, comparing the device identification information in the device characteristic information with the preset identification information in the device identification cache library;
step a4, if target identification information matching with the device identification information exists in the device identification cache library, acquiring device information corresponding to the target identification information, and outputting the device information as the recognition result of the terminal device.
That is, if the correct device address library does not have the target address information matching the device address information, the server compares the device characteristic information with preset characteristic information in a device information cache library (the device information cache library is a preset database for storing the mapping relationship between the device characteristic information and the device information, that is, the device characteristic information contained in the device information cache library includes device address information, device trademark information, device model information, device type information and the like); and if the target characteristic information matched with the equipment characteristic information exists in the equipment information cache library, the server acquires the equipment information corresponding to the target characteristic information, and the server outputs the equipment information as the identification result of the terminal equipment.
If the target characteristic information matched with the equipment characteristic information does not exist in the equipment information cache library, the server compares the equipment identification information in the equipment characteristic information with preset identification information in an equipment identification cache library (the equipment identification cache library is a preset database for storing the mapping relation between the equipment identification information and the equipment information, the equipment identification information contained in the equipment identification cache library comprises equipment address information, equipment host name information, equipment user agent information, equipment user information, equipment characteristic field information and the like), if the target identification information matched with the equipment identification information exists in the equipment identification cache library, the server acquires the equipment information corresponding to the target identification information, and the server outputs the equipment information as the identification result of the terminal equipment.
In this embodiment, the server compares the device information cache library and the device identifier cache library in sequence, and identifies the device information of the terminal device, so that the device information identification is more real-time and accurate. It can be understood that the server may simultaneously use the device information cache library and the device identification cache library to identify the device, and the device information obtained first is used as the device information of the terminal device, or the two device information databases may be used in sequence according to a predetermined time sequence to identify the device.
In addition, in the device information cache library and the device identifier cache library in this embodiment, device feature information of different dimensions is recorded in the device information cache library and the device identifier cache library, respectively, and the server can perform device identification according to the device feature information of different dimensions by setting the device information cache library and the device identifier cache library, so that even if the device features of the terminal device are incomplete, effective device identification can be performed.
Further, referring to fig. 4, on the basis of the above-mentioned embodiment of the present invention, a third embodiment of the terminal device identification method of the present invention is proposed.
This embodiment is a step subsequent to step S21 in the second embodiment, and differs from the above embodiment in that:
step S31, if there is no target feature information matching the device feature information in the preset cache library, inputting the device feature information into a preset recognition engine.
If the target address information matched with the equipment address information does not exist in the preset cache library, the server inputs the equipment characteristic information into a preset identification engine (the preset identification engine refers to a preset equipment information identification algorithm, the preset identification engine is obtained by training through equipment characteristic sample information, and the equipment characteristic sample information comprises the equipment characteristic information and a label representing the equipment information), the server inputs the equipment characteristic information into the preset identification engine, and the preset identification engine is used for obtaining the equipment information of the terminal equipment.
Step S32, processing the device feature information by a preset recognition engine, obtaining device information corresponding to the device feature information, and outputting the device information as a recognition result of the terminal device.
The server processes the device characteristic information through a preset identification engine, obtains device information corresponding to the device characteristic information, and outputs the device information as an identification result of the terminal device. In the embodiment, the equipment information is identified through the preset identification engine, the comprehensiveness of equipment identification is improved, and even if the server does not identify the terminal equipment in the earlier stage, the server can also automatically identify the equipment through the preset identification engine.
Specifically, the preset recognition engine in this embodiment includes a preset device identifier recognition engine (the device identifier recognition engine refers to a device recognition model obtained through device host name information training in advance) and a feature field recognition engine (the feature field recognition engine refers to a device recognition model obtained through device feature field information recognition in advance); the method for identifying the equipment information by the server through the preset equipment identification engine and the characteristic field identification engine comprises the following steps:
b1, if the target characteristic information matched with the equipment characteristic information does not exist in the preset cache library, inputting the equipment characteristic information into the equipment identification recognition engine; processing the device characteristic information through the device identification recognition engine to obtain device information corresponding to the device characteristic information, and outputting the device information as a recognition result of the terminal device;
b2, if the device information output by the device identification recognition engine is not received in a preset first time interval, inputting the device characteristic information into the characteristic field recognition engine; and processing the equipment characteristic information through the characteristic field identification engine to obtain equipment information corresponding to the equipment characteristic information, and outputting the equipment information as an identification result of the terminal equipment.
Namely, the server processes the device feature information through the device identifier recognition engine, obtains device information corresponding to the device feature information, and outputs the device information as a recognition result of the terminal device.
If the preset first time interval (which may be set according to a specific scenario, for example, set to 30s) is not received, the server processes the device feature information through the feature field recognition engine to obtain device information corresponding to the device feature information, and the server outputs the device information as a recognition result of the terminal device.
In the embodiment, the equipment identification is performed through the plurality of identification engines, so that the accuracy of the equipment identification can be ensured, and the identification engines can be simpler.
Further, on the basis of the above-mentioned embodiment of the present invention, a fourth embodiment of the terminal device identification method of the present invention is provided.
This embodiment is the third embodiment step S32: the present embodiment differs from the above embodiments in that, through the steps after the preset recognition engine processes the device feature information:
if the preset second time interval does not receive the equipment information fed back by the preset identification engine, sending the equipment characteristic information to an equipment identification interface;
respectively matching the equipment characteristic information through regular rule sets in the equipment identification interface to obtain a matching result of each regular rule set;
if at least two regular rule sets are successfully matched, acquiring equipment information in each matching result and the reliability weight of the equipment information;
and fusing according to the credibility weight of each piece of equipment information to obtain and output the accessed equipment information of the terminal equipment.
Specifically, if the preset second time interval (which may be set according to a specific scenario, for example, the preset second time interval is set to 1 minute) is not received by the server, that is, the preset recognition engine may not recognize the device information corresponding to the device feature information, at this time, the server sends the device feature information to the device recognition interface; the server respectively matches partial or all information in the equipment characteristic information through the equipment identification interface to respectively obtain the matching result of each regular rule set;
and if only one regular rule set is successfully matched, the server acquires the equipment information in the matching result, and the server takes the equipment information as the equipment information of the accessed terminal equipment and outputs the equipment information.
If at least two regular rule sets are successfully matched, the server fuses according to the credibility weight of each piece of equipment information to obtain and output the accessed equipment information of the terminal equipment, namely, values of the same equipment information obtained in different matching modes are possibly different, for example, equipment brands obtained by matching of different regular rule sets are different, selection is needed to be made from the equipment information.
Specifically, the device information includes multiple fields, and in order to fuse the matching results according to the reliability weight of each matching result to obtain the device information of the terminal device, the server searches for a target field value of each field of the device information, where the target field value is a value of a target field included in a target matching result, and the target matching result is a matching result with the highest reliability weight among all matching results including the target field.
In the embodiment of the invention, the field with the highest credibility weight is respectively obtained from each matching result to form the identification result of the terminal equipment. The higher the reliability weight is, the higher the accuracy of the corresponding field is, and the recognition precision can be effectively improved by adopting the embodiment.
Further, referring to fig. 5, a fifth embodiment of the terminal device identification method of the present invention is proposed on the basis of the above-mentioned embodiment of the present invention.
This embodiment is a step after step S11 in the first embodiment, and is different from the above-described embodiments in that:
step S51, if the correct device address library does not have the target address information matching the device address information, inputting the device feature information into an offline device information statistics library.
If the correct equipment address library does not have target address information matched with the equipment address information, the server adds the accessed equipment characteristic information of the terminal equipment to an offline equipment information statistical library, and the server extracts the equipment address information in the equipment characteristic information.
Step S52, counting the occurrence frequency of each device address information in the offline device information counting library, acquiring high-frequency address information with the occurrence frequency larger than a preset threshold value, and identifying the high-frequency address information to acquire device information corresponding to the high-frequency address information.
The server counts the occurrence frequency of address information of each device in an offline device information statistics library, specifically: the server inquires an offline equipment information statistical library, judges whether the same equipment address information exists in the offline equipment information statistical library or not, and adds one to the occurrence frequency of the equipment address information in the offline equipment information statistical library if the same equipment address information exists in the offline equipment information statistical library; if the same equipment address information does not exist in the offline equipment information statistical library, the server marks the occurrence frequency of the equipment address information in the equipment characteristic information as one time.
It can be understood that, in this embodiment, the statistical duration of the occurrence frequency of the device address information in the device information statistical library under the statistical line can be flexibly set according to a specific scene, for example, the server sets the statistical duration to 7 days, the server counts the occurrence frequency of the device address information in the device information statistical library under the statistical line within 7 days, and the occurrence frequency is updated in real time, for example, the 7 days counted by the server means that the current time is 7 days ahead with the current time as a terminal, the current time is 11 and 22 days in 2019, and the statistical period is from 11 and 22 days in 2019 to 11 and 16 days in 2019; if the current time is 11/23 days in 2019, the statistical period is from 11/23 days in 2019 to 11/17 days in 2019, that is, the server automatically updates the occurrence frequency of the device address information and discards the occurrence frequency which is not in the time period.
The server acquires high-frequency address information of which the occurrence frequency is greater than a preset threshold (the preset threshold refers to a critical value identified by the device feature information, if the occurrence frequency of the device address information is greater than the preset threshold, the server identifies the device feature information to which the device address information belongs, if the occurrence frequency of the device address information is less than or equal to the preset threshold, the server continues to count, the preset threshold in the embodiment can be flexibly set according to a specific scene, for example, the preset threshold is set to be 10), and the server identifies the high-frequency address information to acquire the device information corresponding to the high-frequency address information. Determining the device information through the high-frequency address information may be performed through a preset identification engine, a device identification interface, and the like, which is not described in detail in this embodiment.
And step S53, storing the high-frequency address information and the device information into a correct device address library in a correlated manner so as to update the correct device address library.
