[0067] The features and exemplary embodiments of various aspects of the present application will be described in detail below. In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present application, rather than to limit the present application. For those skilled in the art, the present application can be implemented without the need for some of these specific details. The following description of the embodiments is only to provide a better understanding of the present application by illustrating the examples of the present application.

Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0070] It should be noted that in the embodiments of the present application, certain software, components, models and other existing solutions in the industry may be mentioned, and they should be regarded as exemplary. Their purpose is only to illustrate the feasibility of implementing the technical solution of the present application, but it does not mean that the applicant has or will necessarily use the solution.

[0071] The important data generated by the user when logging in to the server and handling business needs to be sent to the target terminal for storage.

[0072] In the exemplary technology, the server determines the target terminal to which the important data is to be sent. However, due to the important data of different users generated on the server, the server needs to send different important data to the corresponding target terminal. Different target terminals are located in different areas. The server adapts the corresponding data transmission link for different important data, so that the data can be sent to the corresponding target terminal based on the adapted data transmission link.

[0073] The inventors of the present application discovered that the server needs to provide different services to users, and the server is under great pressure to work. The server adapts the data to the data sending link, which increases the workload of the server and leads to poor operational stability of the server.

[0074] The inventor of the present application therefore conceived of automatically identifying the current data reporting mode of the server by the client, so that the client can automatically identify the data sending link adapted for the decrypted data to be sent based on the data reporting mode, without the need for the server to identify and adapt the data sending link, thereby reducing the workload of the server and improving the operating stability of the server.

[0075] Reference Figure 1 , Figure 1 This is a schematic diagram of the scenario of the data transmission method of this application. Figure 1 , the server 100 can be a virtual server corresponding to the cloud or private cloud. The server 100 is provided with a virtual client 110 and a data distribution device 120. The virtual client 100 user stores data, and the data distribution device 120 is used for distributed distribution of data, that is, to distribute the data of different users to the corresponding local client 300. The user logs in to the server 100 and can generate data in the server 100. The data needs to be reported to the target terminal 200 corresponding to the user's location. The server 100 is connected to multiple clients 200. The client 200 is a local client. The client 200 corresponds to a user, who can be an individual user or a user in a group. The server 100 encrypts the data to be sent to obtain encrypted data. The server 100 generates a first descriptor parameter describing the data reporting mode based on its own data reporting mode, and then sends the first descriptor parameter and the encrypted data to the client 100 corresponding to the user. The client 100 determines the current data reporting mode of the server 100 based on the first descriptor parameter, and decrypts the encrypted data to obtain decrypted data. The client 100 then determines the target data sending link and the target terminal based on the current data reporting mode, and the client 100 then sends the decrypted data to the target terminal 300 according to the target data sending link.

[0076] The following combination Figure 1 , the data transmission method of the present application is described in detail.

[0077] Reference Figure 2 , Figure 2 FIG. 1 is a flow chart of a first embodiment of a data transmission method of the present application, which is applied to a client. The data transmission method includes:

[0078] Step S201, receiving encrypted data and a first descriptor parameter sent by a server, where the first descriptor parameter is used to describe a data reporting mode of the server.

[0079] In this embodiment, the execution subject is the client, and the client is a local client configured by the server for the user. The local client is, for example, a computer, a network device, a switch, etc.

[0080] After the user login account generates data on the server side, the data needs to be sent to the target terminal for review or storage. The data can be different types of report data such as financial institution accounts, fund settlement data, replacement resource quotas, and repayments of replacement resources. The server side configures corresponding clients for different users, and the data distribution device in the server side distributes the data generated by different users to the clients corresponding to the users, so that the clients send the data to the target terminal according to the adapted data transmission link. The following is a detailed description of this embodiment using a client sending data to a target terminal.

[0081] After the user logs in to the server, he performs business processing, so that the server generates the data to be sent, which includes account, balance, transaction details and other data. The server encrypts the data to be sent to obtain encrypted data. The server is equipped with different data reporting modes, and different data reporting modes correspond to different data sending links. For example, if the data reporting mode is mode A, the client needs to send data to the target terminal based on a dedicated line. If the data reporting mode is mode B, the client can send data to the target terminal based on the Internet. If the data reporting mode is mode C. The client needs a specified external network to send data to the target terminal. The server obtains the current data reporting mode and generates a descriptor parameter based on the characteristic parameters of the current data reporting mode. The descriptor parameter is defined as the first descriptor parameter. Exemplarily, the current data reporting mode can be determined by the account logged in by the user on the server, the attributes of the data table of the data to be sent, the parameters of the reporting network specified by the account, and the IP address of the client corresponding to the user. The account, the attributes of the data table, the parameters of the reporting network, and the IP address are used as characteristic parameters of the current data reporting network. A characteristic vector is constructed based on each characteristic parameter, and the characteristic vector can be the first descriptor parameter. It can be understood that the first descriptor parameter is used for the data reporting mode of the server.

[0082] The server obtains the first descriptor parameter corresponding to the current data reporting mode, and sends the first descriptor parameter and the encrypted data to the corresponding client, that is, the client receives the encrypted data and the first descriptor parameter sent by the server.

[0083] Step S202: determine the distance between the first descriptor parameter and each stored second descriptor parameter, and use the data reporting mode associated with the second descriptor parameter corresponding to the smallest distance as the current data reporting mode of the server.

[0084] The client stores characteristic parameters of multiple data reporting modes of the server, and can determine the second descriptor parameters of each data reporting mode based on the characteristic parameters, and store each second descriptor parameter in association with the corresponding data reporting mode. The generation process of the second descriptor parameter is consistent with that of the first descriptor parameter, and specifically refers to the generation process of the first descriptor parameter, which will not be repeated here.

[0085] After obtaining the first descriptor parameter, the client determines the distance between the first descriptor parameter and each second descriptor parameter. Exemplarily, the first descriptor parameter and the second descriptor parameter are both vector features, and the Euclidean distance between the first descriptor parameter and the second descriptor parameter is calculated.

[0086] After the client calculates the distance between the first descriptor parameter and each second descriptor parameter, it determines the minimum distance among the distances. The first description parameter and the second description parameter corresponding to the minimum distance are the most matched. The device can then use the data reporting mode associated with the second descriptor parameter corresponding to the minimum distance as the current data reporting mode of the server.

[0087] Step S203, determining the target data transmission link and the target terminal corresponding to the current data reporting mode, and decrypting the encrypted data to obtain decrypted data.

[0088] The client stores the data reporting mode sent by the server, the data sending link and the association relationship between the target terminal. After determining the current data reporting mode of the server, the device obtains the association relationship corresponding to the current data reporting mode. Based on the association relationship, the data sending link and the target terminal corresponding to the current data reporting mode can be determined. The data reporting link is defined as the target data reporting link.

[0089] After the client obtains the encrypted data, it decrypts the encrypted data. Exemplarily, the server stores an encryption key and a decryption key, and the server sends the decryption key to the client. The client decrypts the encrypted data based on the decryption key to obtain the decrypted data.

[0090] Step S204: sending the decrypted data to the target terminal according to the target data sending link.

[0091] After the client determines the target data transmission link and the target terminal, it sends the decrypted data to the target terminal according to the target data transmission link.

[0092] In this embodiment, the encrypted data sent by the server and the first descriptor parameter of the characteristic parameter characterizing the data reporting mode of the server are received, the distance between the first descriptor parameter and each stored second descriptor parameter is determined, the data reporting mode associated with the second descriptor parameter corresponding to the smallest distance is determined as the current data reporting mode of the server, the target data transmission link and the target terminal corresponding to the current data reporting mode are determined, and the encrypted data is decrypted to obtain the decrypted data, so that the decrypted data is sent to the target terminal according to the target data transmission link. In this embodiment, the client automatically identifies the current data reporting mode of the server, so that the client automatically identifies the data transmission link adapted to the decrypted data to be sent based on the data reporting mode, and the server does not need to identify and adapt the data transmission link, which reduces the workload of the server and improves the operation stability of the server.

[0093] Reference Figure 3 , Figure 3 This is a flow chart of the second embodiment of the data transmission method of the present application. Based on the first embodiment, before step S201, it also includes:

[0094] Step S301, obtaining characteristic parameters corresponding to each data reporting mode of the server, and constructing each characteristic point of the data reporting mode at different scales according to the characteristic parameters of the data reporting mode.

[0095] In this embodiment, the client obtains the characteristic parameters of the data reporting mode from the server, and constructs multiple characteristic points of the data reporting mode without passing the scale in the dimension space. The scale control refers to the space formed by the convolution of a two-dimensional Gaussian function of varying scale and the original image (Gaussian blur). Exemplarily, the client constructs a pyramid of Gaussian differences, or uses a box filter and an integral image to implement it. The box filter is used for the second-order partial derivative of the Gaussian to accelerate the construction of the scale space. The image is smoothed by Gaussian kernels of different scales to obtain images of different scales, thereby constructing a pyramid of scale space. Exemplarily, an integral image is constructed based on the characteristic parameters, and a scale space is constructed by the integral image, so that the scale space is used to obtain the characteristic points of the characteristic parameters at different scales.

[0096] Step S302: determining key points among the characteristic points of the data reporting pattern according to a preset matrix.

[0097] After obtaining each feature point, key points are determined in each feature point based on a preset matrix.

[0098] Exemplarily, the preset matrix is, for example, a Hessian matrix, and the determinant of the Hessian matrix is ​​used to perform extreme value detection on feature points in the neighborhood, and feature points that are extreme values ​​are key points.

[0099] Step S303: configure at least one main direction for the key point, and determine the descriptor parameter of the corresponding data reporting mode according to the at least one main direction as the second descriptor parameter associated with the data reporting mode.

[0100] After determining the key point, the client configures at least one main direction for the key point. Exemplarily, the client calculates the wavelet response parameters in the surrounding area of ​​the key point in the integral image. The wavelet response parameters can reflect the gradient information of the local area and can help determine the main direction of the key point. The client determines the reference direction of the key point in the neighborhood based on the wavelet response parameters, and constructs a direction histogram of the key point through the reference direction. The peak of the direction histogram represents the main direction of the neighborhood gradient at the key point.

[0101] After determining at least one main direction, a descriptor parameter of the data reporting mode is determined based on the at least one main direction as a second descriptor parameter associated with the data reporting mode. The second descriptor parameter is a high-dimensional vector, which contains information such as gradient information of the area around the key point and wavelet response parameters. In addition, an integral image can be used to accelerate the calculation of the second descriptor parameter, that is, the normalization process can ensure that the high-dimensional vector has a unit length, thereby enhancing the robustness of the descriptor parameter.

[0102] It should be noted that the generation process of the first description parameter and the generation process of the second descriptor parameter on the server are the same, and will not be described in detail here.

[0103] Step S304: store the data reporting mode in association with the corresponding second descriptor parameter.

[0104] After determining the second descriptor parameter associated with the data reporting mode, the device associates and stores each data reporting mode with the corresponding second descriptor parameter.

[0105] In this embodiment, the client obtains the characteristic parameters corresponding to each data reporting mode of the server, and constructs each characteristic point of the data reporting mode at different scales based on the characteristic parameters of the data reporting mode, determines the key points in each characteristic point based on a preset matrix, and then configures at least one main direction for the key points, so as to accurately obtain the second descriptor parameters associated with the data reporting mode based on at least one main direction.

[0106] Reference Figure 4 , Figure 4This is a flowchart of a third embodiment of the data transmission method of the present application. Based on the first or second embodiment, step S203 includes:

[0107] Step S401, obtaining a first decryption key corresponding to the current data reporting mode.

[0108] Step S402: decrypt the encrypted data according to the first decryption key to obtain decrypted data.

[0109] In this embodiment, the data reporting mode of the server is different, and the encryption method for the sent data is different to enhance the security of the data.

[0110] In one example, the server sends the identifier of the data reporting mode and the associated decryption key to the client. After determining the current data reporting mode of the server, the client determines the identifier of the current data reporting mode as the first identifier, and the device obtains the decryption key associated with the first identifier, thereby decrypting the encrypted data based on the first decryption key to obtain the decrypted data.

[0111] In another example, the data reporting mode of the server has different encryption times for the data to be sent, that is, the server will perform multiple rounds of encryption on the data to be sent. Each data reporting mode has a different number of encryption rounds for the data, and the encryption key of the data reporting mode is different, and the encryption order of the encryption key is also different. For example, the server stores five encryption keys a, b, c, d and e. When the data reporting mode is mode A, the data is encrypted using encryption keys a, b, and c, and the data is first encrypted with a, and then the encrypted data is encrypted again with c, and finally the encrypted data is encrypted by b to obtain the encrypted data; when the data reporting mode is mode B, the data is encrypted using encryption keys d, b, and c, and the data is first encrypted with d, and then the encrypted data is encrypted again with c, and finally the encrypted data is encrypted by b to obtain the encrypted data. The encryption key can also be used as a decryption key to decrypt data, but the encryption order of the encryption key is opposite to the decryption key of the decryption key. For example, encryption key a is used to encrypt data first, but a is used to decrypt, so a is the last to decrypt data. The server sends the identifier of the data reporting mode, each encryption key, and the encryption order of the encryption key to the client. After determining the current data reporting mode of the server, the client obtains the first identifier of the current data reporting mode, obtains each different encryption key associated with the first identifier as the first decryption key and the encryption order, and determines the decryption order of the first decryption key by the encryption order, so as to decrypt the encrypted data in sequence according to the decryption order of each first decryption key to obtain the decryption key. Exemplarily, the current data mode is mode A, the encryption keys are a, b, c, and the encryption order is a, c, b, then each first decryption key is a, b, c, and the decryption order is b, c, a, first use b to decrypt the encrypted data, then use c to decrypt the data decrypted once again, and finally use a to decrypt the data decrypted twice to obtain the decrypted data.

[0112] In this embodiment, the client obtains the first decryption key corresponding to the current data reporting mode, and decrypts the encrypted data based on the first decryption key to obtain accurate decrypted data.

[0113] Reference Figure 5 , Figure 5 This is a flowchart of a fourth embodiment of the data transmission method of the present application. Based on the first or second embodiment, step S203 includes:

[0114] Step S501: obtain the second identifier of the client, and determine the number of the group to which the second identifier belongs.

[0115] In this embodiment, the server performs group encryption based on the client. Exemplarily, the device groups each client, and each group of clients is assigned an encryption key. The data generated by the user corresponding to the client on the server is encrypted using the encryption key of the group to which the client belongs. The server groups the client's identifier, and the server sends the group number and the client's identifier to the client for associated storage. The client obtains the second identifier of the client and determines the number of the group to which the second identifier belongs.

[0116] Step S502: Acquire a decryption key associated with the serial number as a second decryption key, and decrypt the encrypted data according to the second decryption key to obtain decrypted data.

[0117] After the client obtains the number, it can obtain the decryption key associated with the number as the second decryption key, so as to obtain the decrypted data by decrypting the encrypted data based on the second decryption key.

[0118] In this embodiment, the client obtains the decryption key associated with the number based on the number of the group to which its second identification belongs, and decrypts the encrypted data to obtain the decrypted data.

[0119] Reference Figure 6 , Figure 6 This is a flowchart of the fifth embodiment of the data transmission method of the present application, which is applied to the server. The data transmission method includes:

[0120] Step S601, determine the client corresponding to the data to be sent, and obtain characteristic parameters of the current data reporting mode of the server.

[0121] Step S602: determine the first descriptor parameter corresponding to the characteristic parameter, and encrypt the data to be sent to obtain encrypted data.

[0124] Step S603: Send the first descriptor parameter and the encrypted data to the client, so that the client determines the data transmission link of the to-be-transmitted data based on the stored second descriptor parameters and the first descriptor parameters.

[0125] The server obtains the first descriptor parameter corresponding to the current data reporting mode, and sends the first descriptor parameter and the encrypted data to the corresponding client, that is, the client receives the encrypted data and the first descriptor parameter sent by the server.

[0126] The client stores characteristic parameters of multiple data reporting modes of the server, and can determine the second descriptor parameters of each data reporting mode based on the characteristic parameters, and store each second descriptor parameter in association with the corresponding data reporting mode. The generation process of the second descriptor parameter is consistent with that of the first descriptor parameter, and specifically refers to the generation process of the first descriptor parameter, which will not be repeated here.

[0127] After obtaining the first descriptor parameter, the client determines the distance between the first descriptor parameter and each second descriptor parameter. Exemplarily, the first descriptor parameter and the second descriptor parameter are both vector features, and the Euclidean distance between the first descriptor parameter and the second descriptor parameter is calculated.

[0128] After the client calculates the distance between the first descriptor parameter and each second descriptor parameter, it determines the minimum distance among the distances. The first description parameter and the second description parameter corresponding to the minimum distance are the most matched. The device can then use the data reporting mode associated with the second descriptor parameter corresponding to the minimum distance as the current data reporting mode of the server.

[0129] The client stores the data reporting mode sent by the server, the data sending link and the association relationship between the target terminal. After determining the current data reporting mode of the server, the device obtains the association relationship corresponding to the current data reporting mode. Based on the association relationship, the data sending link and the target terminal corresponding to the current data reporting mode can be determined. The data reporting link is defined as the target data reporting link.

[0130] After the client obtains the encrypted data, it decrypts the encrypted data. Exemplarily, the server stores an encryption key and a decryption key, and the server sends the decryption key to the client. The client decrypts the encrypted data based on the decryption key to obtain the decrypted data.

[0131] After the client determines the target data transmission link and the target terminal, it sends the decrypted data to the target terminal according to the target data transmission link.

[0132] In this embodiment, the server encrypts the data to be sent to obtain encrypted data, generates a first descriptor parameter based on the characteristic parameters of the current data reporting mode, and sends the first descriptor parameter and the encrypted data to the server, so that the client determines the current data reporting mode of the server based on the first descriptor parameter and the stored second descriptor parameter, thereby enabling the client to adapt the data sending link without the need for the server to identify and adapt the data sending link, thereby reducing the workload of the server and improving the operating stability of the server.

[0133] In one embodiment, the step of determining the first descriptor parameter corresponding to the feature parameter comprises:

[0134] Construct various characteristic points of the current data reporting mode at different scales according to the characteristic parameters;

[0135] According to the preset matrix, key points are determined among the characteristic points of the current data reporting mode;

[0136] At least one main direction is configured for the key point, and a first descriptor parameter of the current data reporting mode is determined according to the at least one main direction.

[0137] In this embodiment, the server determines the first description parameter of the current data reporting mode based on the characteristic parameters of the current data reporting mode, which is consistent with the generation process of the second descriptor parameter in the above-mentioned second embodiment. Please refer to the second embodiment for details and will not be repeated here.

[0143] The step of encrypting the data to be sent according to the first encryption key to obtain encrypted data comprises:

[0144] The data to be sent are encrypted in sequence according to the encryption order of each first encryption key to obtain encrypted data.

[0145] In this embodiment, the server obtains the encryption key based on the current data reporting mode and encrypts the data. Please refer to the relevant instructions in the third embodiment in which the client decrypts the data based on the decryption key of the current data reporting mode, which will not be repeated here.

[0146] In one embodiment, the step of encrypting the data to be sent to obtain encrypted data includes:

[0147] Obtain the second identifier of the client, and determine the number of the group to which the second identifier belongs;

[0148] An encryption key associated with the serial number is obtained as a second encryption key, and the data to be sent is encrypted according to the second encryption key to obtain encrypted data.

[0149] In this embodiment, the server groups the clients, and the group number determines the encryption password to encrypt the data to be sent. Please refer to the relevant instructions in the fourth embodiment that the client obtains the decryption key based on the group number to decrypt the data, which will not be repeated here.
