and when the target client user name is determined to be the same as the current client user name, determining that the data acquisition client passes the authentication.
In the embodiment of the present invention, because the identity information sent by the data acquisition client is a digital signature encrypted by the data acquisition client through a private key, and the data acquisition server performs configuration of a public key for each data acquisition client in advance, only the data acquisition client configured with the public key can upload data, it is first necessary to decrypt the identity information received by the data acquisition server through the public key set in advance for the client. And then analyzing a current client user name and a client ID contained in the digital signature from the decrypted identity information, determining whether a target client user name corresponding to the client ID in the identity information is the same as the current client user name according to a pre-stored corresponding relationship between the client user name and the client ID, and determining that the data acquisition client passes the authentication when the target client user name is determined to be the same as the current client user name.

The data acquisition client sends the identity information of the data acquisition client, the data to be acquired and the abstract of the data to be acquired to the data acquisition table server after receiving the data acquisition instruction, and whether the abstract of the data acquisition client is the same as the abstract of the data acquisition server or not can be determined based on comparison between the abstract of the data acquisition client and the abstract of the data acquisition server, and the data verification of the data to be acquired is determined to be passed under the condition that the abstract of the data acquisition client is the same as the abstract of the data acquisition server.
As shown in fig. 2, an embodiment of the present invention provides a data acquisition method, which is applied to a data acquisition client, and the method may include the following steps:
step 201: receiving a data acquisition instruction sent by a data acquisition server;

In the embodiment of the invention, in order to ensure the safety of the data acquisition process, an identity authentication link can be set for the data acquisition process so as to verify the identity information of the client. Based on this, after receiving a data acquisition instruction which is sent by the data acquisition server and used for indicating the data which needs to be acquired by the client, the data acquisition server acquires the required data according to the data acquisition instruction, processes the data to be acquired by using a cryptographic hash algorithm, generates an abstract of the data to be acquired, and then sends the identity information, the data to be acquired and the abstract of the data to be acquired to the data acquisition server for identity information authentication. Because the identity of a client is generally verified by inputting a user name and a corresponding password in the conventional data acquisition process, a non-self login situation exists. Therefore, in order to avoid the above situation, the identity information sent by the data acquisition client can be set as a digital signature encrypted by the private key, and the digital signature is encrypted by the private key, so that only the data acquisition client can generate the digital signature and others cannot forge the digital signature, the digital signature can be used as an effective proof of the authenticity of the identity information of the data acquisition client, and meanwhile, the reliability of the data to be acquired can be determined through a data verification feedback result sent by the server. By the method, the data acquisition client does not need to input the corresponding user name and password on the identity authentication interface to verify the identity, and the safety of the data acquisition process can be improved.
In order to determine the data to be collected, in an embodiment of the present invention, after receiving the data collection instruction sent by the data collection server, the method further includes:
analyzing a client data uploading interface number, a server data receiving interface number, data acquisition starting time and data acquisition ending time from a data acquisition instruction;
acquiring data to be acquired between the data acquisition starting time and the data acquisition ending time according to the data acquisition starting time and the data acquisition ending time;
step 204 in the foregoing embodiment is to send the identity information, the data to be collected, and the summary of the data to be collected to the data collection server, which may be specifically implemented in the following manner:
and transmitting the identity information, the data to be collected and the abstract of the data to be collected to an interface corresponding to the server data receiving interface number through an interface corresponding to the client data uploading interface number.
In the embodiment of the invention, the data acquisition instruction is used for indicating the data required to be acquired by the data acquisition client, so that the data acquisition client can firstly analyze the client data uploading interface number, the server data receiving interface number, the data acquisition starting time and the data acquisition ending time from the data acquisition instruction, acquire the data to be acquired between the data acquisition starting time and the data acquisition ending time according to the data acquisition starting time and the data acquisition ending time, and transmit the identity information, the data to be acquired and the abstract of the data to be acquired to the interface corresponding to the server data receiving interface number through the interface corresponding to the client data uploading interface number.
As shown in fig. 3, in order to more clearly illustrate the technical solution and advantages of the present invention, the following detailed description of the data acquisition method provided in the embodiment of the present invention may specifically include the following steps:
step 301: the data acquisition server receives configuration information input from the outside, wherein the configuration information comprises: the data acquisition system comprises a client data uploading interface number, a server data receiving interface number, data acquisition starting time and data acquisition ending time.
For example: assume that externally input configuration information is: content: "1201; 1303, "starttime: "2019-07-0300: 00: 00", endtime: and 2019-07-0400: 00:00, the number of the client data uploading interface is 1201, the number of the server data receiving interface is 1303, and the data acquired by the data acquisition client is data in the time length from 2019-07-0300: 00:00 to 2019-07-0400: 00: 00.
Step 302: and the data acquisition server generates a data acquisition instruction according to the configuration information so that the data acquisition client acquires data between the data acquisition starting time and the data acquisition ending time.
Step 303: and the data acquisition server sends a data acquisition instruction to the data acquisition client so that the data acquisition client acquires the data to be acquired required by the data acquisition instruction.
Step 304: and the data acquisition client receives a data acquisition instruction sent by the data acquisition server.
Specifically, the data acquisition instruction is used for indicating the data required to be acquired by the data acquisition client, so that the data acquisition client can acquire data according to the data acquisition instruction after receiving the data acquisition instruction sent by the data acquisition server, and meanwhile, the data acquisition client cannot upload data at will and can upload data only after receiving the data acquisition instruction sent by the data acquisition server.
Step 305: the data acquisition client analyzes the client data uploading interface number, the server data receiving interface number, the data acquisition starting time and the data acquisition ending time from the data acquisition instruction.
Specifically, the data acquisition client needs to immediately feed back the instruction after receiving the data acquisition instruction, and the data acquisition server determines that the instruction execution fails after 1 minute.
For example, a feedback status code of the data acquisition client can be represented by a code, the data acquisition client feeds back the status code according to a status code specification, and the data acquisition server analyzes the status fed back by the client according to the status code specification; for example, "code": "200", representing "result": "instruction parsing is successful"; "code": "500", representing "result": "instruction resolution failed".
Step 306: and acquiring data to be acquired between the data acquisition starting time and the data acquisition ending time according to the data acquisition starting time and the data acquisition ending time.
Step 307: and the data acquisition client processes the data to be acquired by using a cryptographic hash algorithm to generate an abstract of the data to be acquired.
For example, the data collection client may generate a digest of the data collection client using a cryptographic hash algorithm md5 or SM 3.
Step 308: and the data acquisition client transmits the identity information, the data to be acquired and the abstract of the data to be acquired to the interface corresponding to the server data receiving interface number through the interface corresponding to the client data uploading interface number.
Specifically, the data acquisition client must upload new, modified, and deleted data within a specified time range according to the data instruction requirements. When data is uploaded, the types of the data which are added, modified and deleted are marked through an operation mark in an interface. Where i identifies data representing newly added data, u identifies data representing updated data, and d identifies data representing deleted data. The data body has the limitation of maximum number of data, and the maximum amount of data uploaded in a single time is 100.
For example, the data body data is in a JSON array format, and a single piece of data is also processed in the JSON array format.
Step 309: the data acquisition server receives identity information, data to be acquired and an abstract of the data to be acquired, which are transmitted to an interface corresponding to the server data receiving interface number by the data acquisition client through an interface corresponding to the client data uploading interface number, wherein the identity information is a digital signature encrypted by the data acquisition client through a private key, and the digital signature comprises: the current client user name and the client ID, and the summary of the data to be collected are generated by processing the data to be collected by the data collection client through a password hash algorithm.
Specifically, the data acquisition client may encrypt the identity information through a private key of a public key encryption algorithm RSA or SM2 to obtain a digital signature, and the data acquisition service first verifies the identity of the data acquisition client according to the digital signature and analyzes the data to be acquired after the identity authentication is passed.
Step 310: and the data acquisition server decrypts the identity information through a public key which is set for the client in advance.
Specifically, the data acquisition server can configure the public key of the client through the visual interface, perform authority management on the data liniment client to be acquired, and the client which is not configured with the public key cannot upload data to be acquired.
Step 311: and the data acquisition server analyzes the current client user name and the client ID from the decrypted identity information.
Step 312: and the data acquisition server determines whether a target client user name corresponding to the client ID in the identity information exists in a pre-stored corresponding relationship between the client user name and the client ID.
Step 313: and when the target client user name exists, the data acquisition server determines whether the target client user name is the same as the current client user name.
Step 314: and the data acquisition server determines that the data acquisition client passes the authentication when determining that the target client user name is the same as the current client user name.
Step 315: and the data acquisition server analyzes the data to be acquired sent by the data acquisition client after the data acquisition client passes the authentication.
Step 316: and the data acquisition server side processes the analyzed data to be acquired by utilizing a cipher hash algorithm to generate a data acquisition server side abstract.
Step 317: the data acquisition server determines whether the abstract of the data acquisition server is the same as the abstract sent by the data acquisition client.
Step 318: and the data acquisition server side determines that the data verification of the data to be acquired is passed when determining that the data acquisition server side abstract is the same as the abstract sent by the data acquisition client side.
In particular, in order to prevent the data to be collected from being tampered in the network transmission process. The data acquisition client side can use the cipher hash algorithm md5 or SM3 to generate the digest of the data acquisition client side for the data to be acquired, the data acquisition server side generates the digest of the data acquisition server side through the cipher hash algorithm md5 or SM3, and the two digests are compared, if the two digests are consistent, the data is not tampered, otherwise, the data is tampered.
Step 319: and the data acquisition server stores the data to be acquired when the data verification of the data to be acquired is passed.
