Referring to fig. 2, in an embodiment, the method for identifying a terminal device includes the following steps:
step S10, when network data sent by a terminal device are received, data characteristics corresponding to the network data are obtained, wherein the data characteristics comprise application types and/or application names corresponding to application programs for sending the network data;
in this embodiment, the terminal is a device identifying device, configured to identify different terminal devices, and display device information of the identified terminal devices. Generally, the 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 connected 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 constantly 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 feature includes an application type and/or an application name corresponding to the application program that transmits the network data. Specifically, an application program in the terminal device sends out network data to realize data transmission with other terminals, the application type can include the type of the application program, for example, HTTP application, network streaming media, and the like, and the application name includes the name of the application program, for example, a browser, a mobile phone 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 performs the step of acquiring the data feature corresponding to the network data when the network data sent by the terminal device is received.
Alternatively, the data transmission of part of the terminal devices does not need to pass through the device identification means, whereby the network configuration can be changed so that the network data sent by the terminal devices can reach the device identification means. 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 set in the device identification device, the terminal device sends the network data to the device identification device through the local area network interface, and then forwards the network data to the cloud server through the wide area network interface by the device identification device to realize data transmission, and similarly, when receiving response data fed back by the cloud server, the device identification device can also forward the response data to the terminal device. Or the terminal equipment sends the network data to the equipment identification device through the wide area network interface, and the equipment identification device forwards the network data to the target terminal through the local area network interface to realize data transmission.
Step S20, obtaining the equipment type corresponding to the data characteristic;
in this embodiment, the local database stores a plurality of device types and pre-stored data features corresponding to the plurality of device types, so as to count initial device asset information. After the data characteristics corresponding to the network data are acquired, a pre-stored data characteristic matched with the data characteristics can be searched in a local database, and the equipment type corresponding to the pre-stored data characteristic is used as the equipment type corresponding to the acquired data characteristic, wherein the equipment type can comprise a PC (personal computer), a smart phone and the like. For example, in the case of data features: when the HTTP application and the browser are applied, if the type of the pre-stored equipment corresponding to the pre-stored data feature comprising the data feature is PC, the type of the equipment corresponding to the data feature is PC, namely the terminal equipment is PC.
Optionally, calculating a corresponding characteristic value according to the data characteristic, searching a pre-stored characteristic value matched with the characteristic value in the local database, and taking a pre-stored equipment type corresponding to the pre-stored characteristic value as the equipment type corresponding to the data characteristic. The eigenvalues may be calculated by means of cyclic redundancy check (CRC, cyclic Redundancy Check), MD5 Message-Digest Algorithm (MD 5 Message-Digest Algorithm), etc. 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 is indicated that the device is not present in the device asset, so the feature data may be deleted, skipping the identification of the terminal device. And the matching degree of the identified terminal equipment and the actual equipment asset is higher through the screening of the equipment types.
And step S30, generating equipment identification information according to the equipment 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, and achieve 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 of the device, a device type, a creation time point, and an update time point to supervise the terminal device through the device identification information.
In the technical scheme disclosed in the embodiment, the corresponding equipment type is acquired through the network data sent by the terminal equipment, and then the equipment identification information is generated according to the equipment type, so that the purpose of identifying the terminal equipment is realized, the identification equipment is not required to actively scan and actively identify, but is passively identified according to the access flow sent by the terminal equipment, so that the problem that the response of the terminal equipment cannot be acquired is avoided, and the accuracy of equipment identification is improved.
In another embodiment, as shown in fig. 3, based on the embodiment shown in fig. 2, step S20 includes:
step S21, obtaining a characteristic value corresponding to the data characteristic;
in this embodiment, the feature value corresponding to the data feature may be calculated according to cyclic redundancy check (CRC, cyclic Redundancy Check). The cyclic redundancy check is a channel coding technology for generating short fixed bit check codes according to data such as network data packets or computer files, and is mainly used for detecting or checking errors possibly occurring after data transmission or storage. It uses the principle of division and remainder to make error detection.
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, cyclic redundancy check is performed on the application type to obtain a first check value so as to extract important features in the application type, and cyclic redundancy check is performed on the application name to obtain a second check value so as to extract important features in the application name. And comprehensively calculating a CRC check value, namely a third check value, of the first check value and the second check value 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, obtaining a pre-stored characteristic value matched with the characteristic value;
step S23, obtaining the matched pre-stored equipment type associated with the pre-stored characteristic value;
and step S24, taking the obtained pre-stored equipment type as the equipment 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 strategy is configured in a local database in advance, that is, a plurality of pre-stored characteristic values and pre-stored equipment types associated with the pre-stored characteristic values are pre-stored, so that the pre-stored characteristic values matched with the characteristic values are searched in the local database, and the pre-stored equipment types associated with the pre-stored characteristic values are used as equipment types corresponding to the characteristic values.
Alternatively, when configuring the identification policy, a plurality of preset application types and preset application names may be manually acquired, and a device having the plurality of preset application types and preset application names may be used as an initial device asset. And equally, performing cyclic redundancy check on the preset application type and the preset application name to calculate a preset characteristic value of the cyclic redundancy check, taking the preset characteristic value and the equipment type of the terminal equipment with the preset application type and the preset application name as an identification strategy, and pre-storing the identification strategy in a local database.
Alternatively, if there is no pre-stored characteristic value matching the characteristic value, this indicates that the device is not present in the device asset, and therefore the characteristic data may be deleted, bypassing 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 can be searched according to the hash address, so that the searching efficiency is improved, and the identification speed of the terminal equipment is improved. 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 obtained at a position corresponding to the hash address in a 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 can not be obtained according to the hash address. It should be noted that, when the pre-stored feature value is pre-stored in the local database, the method may be performed in a hash storage manner, first, a hash address corresponding to the pre-stored feature value is calculated through a hash function, and the pre-stored feature value is stored in a storage area corresponding to the hash address, so that the pre-stored feature value is conveniently searched for according to the hash address.
Optionally, the pre-stored device type is stored in a hash table. Specifically, the pre-stored equipment type is stored in the hash address corresponding to the pre-stored characteristic value, so that the pre-stored equipment type can be directly obtained according to the hash address corresponding to the characteristic value.
In the technical scheme disclosed in the embodiment, the characteristic value corresponding to the data characteristic is obtained, the equipment type corresponding to the data characteristic is searched according to the characteristic value, and the characteristic data is matched through the characteristic value calculated by the CRC, 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, step S30 includes:
step S31, obtaining the network address of the terminal equipment according to the network data;
in the present embodiment, when device identification information is generated according to the device type, the network address of the terminal device is acquired according to the network data. Since the network data is sent by the terminal device, the data packet of the network data can obtain the identity information such as the IP address of the terminal device, and the identity information is used for distinguishing different terminal devices.
And step S32, generating the equipment identification information according to the network address and the equipment type.
In this embodiment, after the network address is acquired, the device identification information is generated according to the network address and the device type. The device identification information includes information such as network address and device type for the user to make statistics of the device asset.
Alternatively, when the device identification information is generated according to the network address and the device type, whether pre-stored device identification information matched with the network address exists in a device information database or not may be detected, wherein a plurality of pre-stored device identification information is pre-stored in the device information database. When the pre-stored network address in the pre-stored equipment identification information is consistent with the network address, the pre-stored equipment identification information is judged to be matched with the network address, and the information of the equipment is stored in an equipment information database. When the pre-stored network address in the pre-stored equipment identification information is inconsistent with the network address, the pre-stored equipment identification information is not matched with the network address, the information of the equipment is not stored in the equipment information database,
alternatively, 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. When the pre-stored equipment identification information matched with the network address exists, the pre-stored equipment identification information needs to be updated, and the updated pre-stored equipment identification information is used as equipment identification information.
Optionally, when generating the new device identification information, the current time point is acquired, and the new device identification information is generated according to the network address, the device type and the current time point. Wherein the current time point is taken as a creation time point and an update time point in the device identification information.
Optionally, when updating the pre-stored equipment identification information, updating the updating time point in the pre-stored equipment identification information according to the current time point, and updating the equipment type in the pre-stored equipment identification information according to the equipment type, so as to realize updating of the equipment information.
In the technical scheme disclosed in the embodiment, the network address corresponding to the terminal equipment is acquired according to the network data, and the equipment identification information is generated according to the network address and the equipment type, so that the purposes of identifying the terminal equipment in the equipment asset and generating the corresponding equipment information are realized, and the follow-up statistics of the equipment asset by a user is facilitated.

step S40, obtaining an updating time point corresponding to the equipment identification information;
and S50, deleting the equipment identification information when the time interval between the updated time point and the current time point is larger than a preset interval.

When the time interval between the updated time point and the current time point is larger than the preset interval, the terminal equipment corresponding to the equipment identification information is indicated to be abandoned or cleaned, and the equipment identification information can be deleted to monitor equipment assets.
Optionally, the device identification information is stored in the device information database, and the device identification apparatus may continuously acquire data of the device information database, and display the acquired device identification information on a front-end interface of the device identification apparatus, so as to allow a user to view and count.
Optionally, after the device identification information corresponding to the terminal device is generated, the device identification information is stored in a structure. A structure is a collection of data that is made up of a series of data of the same type or different types. By storing the device identification information by way of the structure, the operation can be simplified, facilitating subsequent searching of the device identification information, for example, the content of a single structure may include: device network address, device type, creation time point, update time point.
