All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The terminology used in the embodiments of the present application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used in the examples of this application and the appended claims, the singular forms "a", "an", and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.
It should be understood that the term "and/or" as used herein is merely one type of associative relationship that describes an associated object, meaning that three types of relationships may exist, e.g., A and/or B, may mean: a exists alone, A and B exist simultaneously, and B exists alone. In addition, the character "/" herein generally indicates that the former and latter related objects are in an "or" relationship.
Referring to fig. 1, a schematic view of an application scenario provided in the embodiment of the present application is shown. In fig. 1, 1 server 101 and 3 image forming apparatuses 102 are shown, and the server 101 and the image forming apparatuses 102 communicate with each other via a network.
In this application scenario, the communication mode between the server 101 and the image forming apparatus 102 may be wired communication or wireless communication, wherein the wireless communication may be a Near Field Communication (NFC) network such as a Wi-Fi hotspot network, a Wi-Fi P2P network, a bluetooth network, a zigbee network or a Near Field Communication (NFC) network; or a third-generation wireless telephone technology (3G) network, a fourth-generation mobile communication technology (4G) network, a fifth-generation mobile communication technology (5G) network, a future-evolution Public Land Mobile Network (PLMN), the internet, or the like. This is not particularly limited by the examples of the present application.
It should be noted that the application scenario shown in fig. 1 is only an exemplary description, and should not be taken as a limitation to the scope of the present application. For example, the image forming apparatus may be replaced with another communication apparatus such as a television, a refrigerator, or the like, which is not limited herein. The image forming apparatus may be a copying machine, a facsimile machine, a multifunction image forming and copying apparatus, an electrostatic printing apparatus, or the like, in addition to the printer.
In practical applications, cluster management software may be deployed in the server, and the cluster management software collects information of the image forming apparatuses, which may include image forming apparatus information and/or consumable information, through the network. For example, the current state of the image forming apparatus, the serial number of the image forming apparatus, the IP address of the image forming apparatus, the firmware version of the image forming apparatus; consumable serial number, consumable remaining amount, number of printed pages, etc.
However, in the prior art, the server collects the information of the image forming apparatus only through a single channel, and this method is easily intercepted and tampered by a third party with a malicious means, so that the cluster management center cannot obtain the real information of the image forming apparatus. Here, the single channel may be understood as meaning that the server and the image forming apparatus establish only one network connection channel through which communication is performed.
Based on this, the embodiment of the application provides an information collection method, a communication device, a server, a system and a storage medium, so as to be beneficial to solving the problems that information is transmitted in a single-channel form in a network and is easily intercepted and tampered by a third party in a malicious way in the prior art. The details will be described below.
Referring to fig. 2, a schematic diagram of a dual channel communication scenario provided in the embodiment of the present application is shown. As shown in fig. 2, in the embodiment of the present application, the server and the image forming apparatus establish a first communication connection and a second communication connection, respectively, that is, the server and the image forming apparatus can perform information interaction through the first communication connection and the second communication connection, respectively. The data transmitted through the first communication connection and the second communication connection are mutually verified, so that the accuracy of the data collected by the server can be ensured.
In some possible implementations, the first communication connection and the second communication connection belong to different communication modes. For example, the first communication connection is a wired network or a Wi-Fi network; the second communication connection is a mobile communication network, such as a 2G, 3G, 4G or 5G network, and is not limited herein. Of course, those skilled in the art may also configure other network modes according to practical application scenarios, and this is not limited in this application embodiment.
In some possible implementations, the wired network or Wi-Fi network is used to transmit traffic data; the mobile communication network is used for transmitting the check data corresponding to the service data.
It should be noted that the application scenario shown in fig. 2 is only an exemplary description, and should not be taken as a limitation to the scope of the present application. For example, the image forming apparatus may be other communication apparatus.
Referring to fig. 3, a schematic flow chart of an information collection method provided in the embodiment of the present application is shown. The method can be applied to the application scenario shown in fig. 2, as shown in fig. 3, which mainly includes the following steps.
Step S301: the communication device transmits first data to the server through the first communication connection.
Specifically, the first data is service data. Taking the communication device as an image forming device as an example, the first data may correspond to image forming device information and/or consumable information. For example, the current state of the image forming apparatus, the serial number of the image forming apparatus, the IP address of the image forming apparatus, the firmware version of the image forming apparatus; consumable serial number, consumable remaining amount, number of printed pages, etc.
In some possible implementations, the first communication connection is a wired network or a Wi-Fi network. Of course, those skilled in the art may also use other communication modes to establish the first communication connection, and the embodiment of the present application is not limited thereto.
Step S302: the communication device sends second data to the server via a second communication connection.
Specifically, the second data is check data corresponding to the service data, the second data is associated with the first data, and the second data is used for checking the first data. That is, the server may receive the first data and the second data at the same time, and then perform mutual verification through the first data and the second data, which may ensure accuracy of the collected data.
In some possible implementations, the second communication connection may be a mobile communication network. Of course, those skilled in the art may also use other communication modes to establish the second communication connection, and the embodiment of the present application is not limited thereto.
In some possible implementations, the first communication connection and the second communication connection belong to different communication modes. For example, the first communication connection is a Wi-Fi network and the second communication connection is a mobile communication network. It can be understood that by adopting the configuration mode, a third party can be prevented from adopting a malicious means to intercept the first data and the second data at the same time, and the communication safety is improved.
In some possible implementations, the first communication connection may also be a mobile communication network, and the second communication connection is a Wi-Fi network, which is not limited herein.
In practical applications, the second data may be generated according to a preset first algorithm based on the first data.
Specifically, the first algorithm may be at least one of an encryption and decryption algorithm, a hash calculation, and an MD5 algorithm, which is not specifically limited by the embodiment of the present application.
In order to facilitate a better understanding of the technical solution for those skilled in the art, the following three ways are used to describe the process of acquiring the second data.
Firstly, encrypting the first data through a preset secret key and/or an encryption algorithm to obtain second data.
And secondly, carrying out hash operation on the first data to obtain a first hash value, wherein the first hash value is the second data.
Thirdly, carrying out hash operation on the first data to obtain a first hash value; and encrypting the first hash value through a preset secret key and/or an encryption algorithm to obtain second data.
Of course, the skilled person may also configure the second data in other manners, such as performing the MD5 algorithm on the first data to obtain an MD5 value as the second data, and of course, the second data may also be generated according to a plurality of algorithms in the above-mentioned first algorithm based on the first data, which is not limited in particular by the embodiment of the present application.
Step S303: and the server verifies the first data and the second data.
Specifically, after the server receives the first data and the second data through the first connection and the second connection, the server may check the first data and the second data to verify whether the first data and the second data are matched.
In specific implementation, third data can be obtained according to a preset second algorithm based on the second data, and the first data is verified through the third data; and/or obtaining fourth data according to a preset third algorithm based on the first data, and verifying the second data through the fourth data.
It can be understood that the verification process of the first data and the second data matches the generation mode of the second data. That is, the second algorithm and the third algorithm according to the embodiments of the present application are matched to the first algorithm.
For example, if the second data is obtained by "encrypting the first data by using a preset key and/or an encryption algorithm to obtain the second data" in the first manner, the corresponding verification process is as follows: decrypting the second data through a preset secret key and/or an encryption algorithm; and verifying the first data through the decrypted data. If the decrypted data is consistent with the first data and indicates that the data is not tampered, the verification is passed; otherwise, the check fails.
Or, encrypting the first data through a preset key and/or an encryption algorithm; and verifying the second data through the encrypted data. If the encrypted data is consistent with the second data, the data is not tampered, and the verification is passed; otherwise, the check fails.
If the second data is obtained by performing hash operation on the first data in the second manner to obtain a first hash value, where the first hash value is obtained as the second data, the corresponding verification process is as follows: performing hash operation on the first data to obtain a second hash value; and checking the second hash value through the first hash value. If the first hash value is consistent with the second hash value, the data is not tampered, and the verification is passed; otherwise, the check fails.
If the second data adopts the third mode, performing hash operation on the first data to obtain a first hash value; encrypting the first hash value through a preset secret key and/or an encryption algorithm to obtain second data, wherein the corresponding verification process is as follows: decrypting the second data through a preset secret key and/or an encryption algorithm to obtain a first hash value; performing hash operation on the first data to obtain a second hash value; and checking the second hash value through the first hash value. If the first hash value is consistent with the second hash value, the data is not tampered, and the verification is passed; otherwise, the check fails.
Step S304: and if the verification is passed, storing the first data.
It can be understood that if the verification is passed and the data is not tampered, the first data is stored, and the data collection is completed; otherwise, the first data is discarded.
In the embodiment of the application, data collection is performed in a double-channel mutual verification mode, and the integrity and accuracy of collected data are guaranteed.
In order to facilitate understanding of the technical solutions provided in the embodiments of the present application, the following describes an information collection method provided in the embodiments of the present application, taking an image forming apparatus as an example.
Referring to fig. 4, a schematic structural diagram of an image forming apparatus according to an embodiment of the present disclosure is shown.
