Referring to fig. 2, in an embodiment, the method for identifying the terminal device includes the following steps:
step S10, when receiving network data sent by a terminal device, obtaining data characteristics corresponding to the network data, wherein the data characteristics include an application type and/or an application name corresponding to an application program sending the network data;
in this embodiment, the terminal in this embodiment is an apparatus identification device, and is configured to identify different terminal apparatuses and display apparatus information of the identified terminal apparatuses. Generally, a terminal device is not a completely isolated terminal, and needs to perform data interaction with other devices frequently to transfer various data information. The terminal equipment is accessed to the equipment identification device through the setting of the network interface, and the network data is transmitted with other equipment through the identification device, so that the equipment identification device can regularly receive the network data sent by the terminal equipment. And when receiving the network data sent by the terminal equipment, acquiring the data characteristics corresponding to the network data.
Optionally, the data characteristics include an application type and/or an application name corresponding to an application program that transmits the network data. Specifically, an application program in the terminal device sends out network data to implement data transmission with other terminals, the application type may include a type of the application program, such as an HTTP application, a network streaming media, and the like, and the application name includes a name of the application program, such as a browser, a mobile video player, and the like.
Optionally, the device identification function of the device identification apparatus is started in advance, so that the device identification apparatus executes a step of acquiring a data feature corresponding to the network data when receiving the network data sent by the terminal device.
Alternatively, the data transmission of part of the terminal equipment does not need to pass through the equipment identification device, so that the network configuration can be changed, and the network data sent by the terminal equipment can reach the equipment identification device. For example, as shown in fig. 6, fig. 6 is a schematic diagram of a transmission manner of network data, a local area network interface and a wide area network interface are arranged in the device identification apparatus, the terminal device sends the network data to the device identification apparatus through the local area network interface, and then forwards the network data to the cloud server through the device identification apparatus through the wide area network interface, so as to implement data transmission. Or the terminal equipment sends the network data to the equipment identification device through the wide area network interface, and then the network data is forwarded to the target terminal through the equipment identification device through the local area network interface, so that the data transmission is realized.
Step S20, acquiring the device type corresponding to the data characteristics;
in this embodiment, the local database stores a plurality of device types and pre-stored data characteristics corresponding to the plurality of device types, so as to count initial device asset information. After the data features corresponding to the network data are obtained, pre-stored data features matched with the data features can be searched in a local database, and the device types corresponding to the pre-stored data features are used as the device types corresponding to the obtained data features, wherein the device types can include PCs, smart phones and the like. For example, in the case of data characteristics: when the HTTP applies and the browser, if the pre-stored device type corresponding to the pre-stored data feature including the data feature is a PC, it indicates that the device type corresponding to the data feature is a PC, that is, the terminal device is a PC.
Optionally, the corresponding characteristic value is calculated according to the data characteristic, a pre-stored characteristic value matched with the characteristic value in the local database is searched, and a pre-stored device type corresponding to the pre-stored characteristic value is used as the device type corresponding to the data characteristic. The characteristic value can be calculated by means of Cyclic Redundancy Check (CRC), MD5 information Digest Algorithm (MD5 Message-Digest Algorithm), and the like. The local database stores a plurality of pre-stored characteristic values and pre-stored equipment types associated with the pre-stored characteristic values.
Alternatively, when the device type corresponding to the data feature does not exist in the local database, it indicates that the device does not exist in the device asset, and therefore the feature data may be deleted, skipping the identification of the terminal device. Through the screening of the device types, the matching degree of the identified terminal device and the actual device assets is higher.
Step S30, generating device identification information according to the device type.
In this embodiment, when the device type corresponding to the data feature is obtained, it indicates that the terminal device exists in the device asset, so that other identity information in the received network data may be obtained, so as to generate device identification information according to the other identity information and the device type, thereby achieving the purpose of identifying the device asset. The device identification information is used for recording the identity of the terminal device and distinguishing the terminal device from other terminal devices. The device identification information may include at least one of a network address, a device type, a creation time point, and an update time point of the device to supervise the terminal device by the device identification information.
In the technical scheme disclosed in this embodiment, the corresponding device type is acquired through the network data sent by the terminal device, and then the device identification information is generated according to the device type, so that the purpose of identifying the terminal device is achieved, and the device is passively identified according to the access flow sent by the terminal device without active scanning and active identification, so that the problem that the response of the terminal device cannot be acquired is avoided, and the accuracy of device identification is improved.
In another embodiment, as shown in fig. 3, on the basis of the embodiment shown in fig. 2, the step S20 includes:
step S21, acquiring a characteristic value corresponding to the data characteristic;
in this embodiment, the characteristic value corresponding to the data characteristic may be calculated according to a Cyclic Redundancy Check (CRC). Cyclic redundancy check is a channel coding technique that generates a short fixed bit check code from data, such as network packets or computer files, and is mainly used to detect or check errors that may occur after data transmission or storage. It uses the principle of division and remainder to detect the error.
Alternatively, when the data feature includes both the application type and the application name, the check value of the CRC thereof may be calculated for the application type and the application name, respectively. Specifically, the application type is subjected to cyclic redundancy check to obtain a first check value so as to extract the important features in the application type, and the application name is subjected to cyclic redundancy check to obtain a second check value so as to extract the important features in the application name. And then, comprehensively calculating the CRC check value of the first check value and the second check value, namely a third check value, so as to extract important features in the first check value and the second check value, and taking the third check value as a feature value corresponding to the data feature.
Step S22, acquiring a pre-stored characteristic value matched with the characteristic value;
step S23, obtaining the pre-stored device type associated with the matched pre-stored characteristic value;
and step S24, taking the obtained pre-stored device type as the device type corresponding to the characteristic value.
In this embodiment, after the feature value corresponding to the data feature is obtained, the device type corresponding to the feature value is searched in the local database. Specifically, an identification policy is configured in the local database in advance, that is, a plurality of pre-stored characteristic values and pre-stored device types associated with the pre-stored characteristic values are stored in advance, so that the pre-stored characteristic values matched with the characteristic values are searched in the local database, and the pre-stored device types associated with the pre-stored characteristic values are used as the device types corresponding to the characteristic values.
Optionally, when configuring the identification policy, the multiple preset application types and preset application names may be manually obtained, and the device with the multiple preset application types and preset application names may be used as the initial device asset. Similarly, performing cyclic redundancy check on the preset application type and the preset application name to calculate a preset characteristic value thereof, and using the preset characteristic value and the device type of the terminal device with the preset application type and the preset application name as an identification strategy and prestoring the identification strategy in a local database.
Optionally, when there is no pre-stored feature value matching the feature value, it indicates that the device is not present in the device asset, and therefore the feature data may be deleted, skipping the identification of the terminal device.
Optionally, whether a pre-stored characteristic value matched with the characteristic value exists in the local database or not is searched, and the search can be performed according to the hash address, so that the search efficiency is improved, and the identification speed of the terminal device is increased. Specifically, a hash address corresponding to the feature value is calculated through a hash (hash) function, and then a pre-stored feature value matched with the feature value is acquired from a position corresponding to the hash address in the memory. If the pre-stored characteristic value matched with the characteristic value exists, the pre-stored characteristic value can be obtained according to the Hash address, and if the pre-stored characteristic value matched with the characteristic value does not exist, the pre-stored characteristic value cannot be obtained according to the Hash address. It should be noted that, when the pre-stored characteristic value is pre-stored in the local database, the pre-stored characteristic value may be stored in a hash storage manner, and first, a hash address corresponding to the pre-stored characteristic value is calculated through a hash function, and the pre-stored characteristic value is stored in a storage area corresponding to the hash address, so as to search the pre-stored characteristic value according to the hash address in the following.
Optionally, the pre-stored device types are stored in a hash table. Specifically, the pre-stored device type is stored in the hash address corresponding to the pre-stored characteristic value, so that the pre-stored device type can be directly obtained subsequently according to the hash address corresponding to the characteristic value.
In the technical scheme disclosed in this embodiment, the feature value corresponding to the data feature is obtained, the device type corresponding to the data feature is searched according to the feature value, and the feature value calculated through the CRC is used to match the feature data, so that the matching efficiency is higher.
In yet another embodiment, as shown in fig. 4, on the basis of the embodiment shown in any one of fig. 2 to 3, the step S30 includes:
step S31, acquiring the network address of the terminal device according to the network data;
in the present embodiment, when generating the device identification information according to the device type, the network address of the terminal device is acquired from the network data. Since the network data is sent by the terminal device, the identity information such as the IP address of the terminal device can be obtained from the data packet of the network data, so as to distinguish different terminal devices.
Step S32, generating the device identification information according to the network address and the device type.
In this embodiment, after the network address is obtained, device identification information is generated according to the network address and the device type. The equipment identification information comprises information such as network addresses and equipment types, and is used for users to count equipment assets.
Optionally, when the device identification information is generated according to the network address and the device type, it may be further detected whether pre-stored device identification information matching the network address exists in a device information database, where a plurality of pieces of pre-stored device identification information are pre-stored in the device information database. And when the prestored network address in the prestored equipment identification information is consistent with the network address, judging that the prestored equipment identification information is matched with the network address, wherein the information of the equipment is stored in an equipment information database. When the pre-stored network address in the pre-stored device identification information is not consistent with the network address, the pre-stored device identification information is judged not to be matched with the network address, the information of the device is not stored in the device information database,
optionally, when there is no pre-stored device identification information matching the network address, new device identification information needs to be generated and added to the device information database. And when the pre-stored equipment identification information matched with the network address exists, updating the pre-stored equipment identification information, and taking the updated pre-stored equipment identification information as the equipment identification information.
