[0071] Important data generated by the user after logging in to the server to handle business needs to be sent to the target terminal for storage.

[0072] In an example technology, the server determines a target terminal to which important data is to be sent. However, the server needs to send different important data to different target terminals, and the different target terminals are located in different areas. The server needs to adapt a corresponding data sending link for different important data, so that the data can be sent to the corresponding target terminal based on the adapted data sending link.

[0073] The inventors of the present application find that the server needs to provide different services for users, and the working pressure of the server is relatively large. The server adapts a data sending link for data, which increases the working load of the server and causes poor running stability of the server.

[0074] The inventors of the present application therefore think that the current data reporting mode of the server is automatically recognized by the client, so that the client automatically recognizes the data sending link to which the decrypted data to be sent is adapted based on the data reporting mode. The server does not need to adapt and recognize the data sending link, which reduces the working load of the server and improves the running stability of the server.

[0075] Reference is made to Figure 1 , Figure 1 which is a scene schematic diagram of the data transmission method of the present application. Reference is made to Figure 1 , the server 100 can be a virtual server corresponding to a cloud or a private cloud. The server 100 is provided with a virtual client 110 and a data distribution device 120. The virtual client 100 stores data of a user. The data distribution device 120 is used for distributed distribution of data, i.e., distribution of data of different users to corresponding local clients 300. The user logs in the server 100, and can generate data in the server 100. The data needs to be reported to a target terminal 200 corresponding to a location of the user. The server 100 connects a plurality of clients 200, and the client 200 is a local client. The client 200 corresponds to a user, which can be a personal user or a user in a group. The server 100 encrypts the data to be sent to obtain encrypted data, generates a first descriptor parameter describing a data reporting mode based on the data reporting mode of the server 100, and 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, decrypts the encrypted data to obtain decrypted data, determines a target data sending link and a target terminal based on the current data reporting mode, and sends the decrypted data to the target terminal 300 according to the target data sending link.

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

[0077] Reference is made to​Figure 2 , Figure 2 The flowchart shown is a first embodiment of the data transmission method of the present application, applied to a client. The data transmission method comprises:

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

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

[0080] After the user logs in the account and generates data on the server, the data needs to be sent to a target terminal for auditing or storage. The data can be different types of report data such as financial institution accounts, fund settlement data, replacement resource quotas, and repayment of replacement resources. The server configures corresponding clients for different users, and the data distribution device in the server distributes the data generated by different users to the corresponding clients of the users in a distributed manner, so that the clients send the data to the target terminal according to the adaptive data transmission link. The following describes in detail the embodiment by taking a client sending data to a target terminal.

[0081] After the user logs in the server for business processing, the server generates to-be-sent data, which includes account, balance, transaction details, etc. The server encrypts the to-be-sent data to obtain encrypted data. The server sets different data reporting modes, and the corresponding data transmission links are different for different data reporting modes. For example, if the data reporting mode is A mode, the client needs to send data to the target terminal based on a private line. If the data reporting mode is B mode, the client can send data to the target terminal based on the Internet. If the data reporting mode is C mode, the client needs to send data to the target terminal through a specified external network. The server obtains the current data reporting mode, generates a descriptor parameter based on the characteristic parameters of the current data reporting mode, and defines the descriptor parameter as the first descriptor parameter. For example, the current data reporting mode can be determined by the account of the user logged in the server, the attributes of the data table of the to-be-sent data, 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 the characteristic parameters of the current data reporting network, a feature vector is constructed based on each characteristic parameter, and the feature vector is 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 sending 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] In step S202, the distances between the first descriptor parameter and each of the stored second descriptor parameters are determined, and the data sending mode associated with the second descriptor parameter corresponding to the smallest distance is determined as the current data sending mode of the server.

[0084] The client stores the characteristic parameters of multiple data sending modes of the server, can determine the second descriptor parameter of each data sending mode based on the characteristic parameters, and stores each second descriptor parameter in association with the corresponding data sending mode. The generation process of the second descriptor parameter is consistent with that of the first descriptor parameter, and details are described above and will not be repeated here.

[0085] After the client obtains the first descriptor parameter, the distances between the first descriptor parameter and each of the second descriptor parameters are determined. For example, 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 distances between the first descriptor parameter and each of the second descriptor parameters, the smallest distance is determined among the distances, and the first descriptor parameter and the second descriptor parameter corresponding to the smallest distance are the most matched. The device can determine the data sending mode associated with the second descriptor parameter corresponding to the smallest distance as the current data sending mode of the server.

[0087] In step S203, the target data sending link and the target terminal corresponding to the current data sending mode are determined, and the encrypted data is decrypted to obtain decrypted data.

[0088] The client stores the association relationship between the data sending mode, the data sending link and the target terminal sent by the server. After the device determines the current data sending mode of the server, the association relationship corresponding to the current data sending mode is obtained, and the data sending link and the target terminal corresponding to the current data sending mode are determined based on the association relationship. The data sending link is defined as the target data sending link.

[0089] After the client obtains the encrypted data, the encrypted data is decrypted. For example, 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] In step S204, the decrypted data is sent to the target terminal according to the target data sending link.

[0091] The client determines the target data sending link and the target terminal, and sends the decrypted data to the target terminal according to the target data sending link.

[0092] In this embodiment, the client receives the encrypted data and the first descriptor parameter representing the feature parameter of the data sending mode of the server, determines the distance between the first descriptor parameter and each stored second descriptor parameter, determines the data sending mode associated with the second descriptor parameter corresponding to the minimum distance as the current data sending mode of the server, determines the target data sending link and the target terminal corresponding to the current data sending mode, and decrypts the encrypted data to obtain decrypted data, so as to send the decrypted data to the target terminal according to the target data sending link. In this embodiment, the client automatically identifies the current data sending mode of the server, so that the client automatically identifies the data sending link to which the decrypted data to be sent is adapted based on the data sending mode, without the server identifying and adapting the data sending link, thereby reducing the work load of the server and improving the operation stability of the server.

[0093] Referring to Figure 3 , Figure 3 This is a flowchart of a second embodiment of the data transmission method of the application. Based on the first embodiment, before step S201, the following steps are further included.

[0094] In step S301, the feature parameters corresponding to each data sending mode of the server are obtained, and each feature point of the data sending mode under different scales is constructed according to the feature parameters of the data sending mode.

[0095] In this embodiment, the client obtains the feature parameters of the data sending mode from the server, and constructs multiple feature points of the data sending mode under different scales in the size space. The scale control refers to a space formed by convolving a two-dimensional Gaussian function with a variable scale with an original image (Gaussian blur). For example, the client constructs a Gaussian difference pyramid, or uses a box filter and an integral image to achieve this. The box filter is used for the second-order partial derivative of Gaussian to accelerate the construction of the scale space. The image is smoothed by a Gaussian kernel of different scales to obtain an image of different scales, thereby constructing a pyramid of the scale space. For example, the integral image is constructed based on the feature parameters, the scale space is constructed by the integral image, and the feature points of the feature parameters under different scales are obtained by using the scale space.

[0096] In step S302, the key points are determined in each feature point of the data sending mode according to a preset matrix.

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

[0098] For example, the preset matrix is a Hessian matrix, and the determinant of the Hessian matrix is used to detect extreme values in the neighborhood of the feature point, and the feature point that is an extreme value is a key point.

[0099] In step S303, at least one main direction is configured for the key point, and a descriptor parameter of a corresponding data reporting mode is determined according to the at least one main direction as a second descriptor parameter associated with the data reporting mode.

[0100] After the key point is determined, the client configures at least one main direction for the key point. For example, the client calculates a wavelet response parameter in a surrounding area of a position of the key point in the integral image. The wavelet response parameter can reflect gradient information of the local area, and can help to determine the main direction of the key point. The client determines a reference direction of the key point in the neighborhood based on the wavelet response parameter, constructs a direction histogram of the key point through the reference direction, and a peak value of the direction histogram represents the main direction of the gradient in the neighborhood of the key point.

[0101] After the at least one main direction is determined, a descriptor parameter of a 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, and includes gradient information of a surrounding area of the key point, a wavelet response parameter, and the like. In addition, the integral image can be used to accelerate the calculation of the second descriptor parameter, that is, through normalization processing, the high-dimensional vector can be ensured to have a unit length, thereby enhancing the robustness of the descriptor parameter.

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

[0103] In step S304, the data reporting mode is stored in association with the corresponding second descriptor parameter.

[0104] After the second descriptor parameter associated with the data reporting mode is determined, the device stores each data reporting mode in association with the corresponding second descriptor parameter.

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

[0106] Reference Figure 4 , Figure 4For the flowchart of the third embodiment of the data transmission method of the present application, based on the first or second embodiment, step S203 comprises:

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

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

[0109] In the present embodiment, the data reporting mode of the server is different, and the encryption mode of the data to be sent is different, so as to enhance the security of the data.

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

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

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

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

[0114] In step S501, the second identification of the client is obtained, and the number of the group in which the second identification is located is determined.

[0115] In this embodiment, the server encrypts based on the grouping of the clients. For example, the device groups the clients, each group of clients is assigned an encryption key, and the data generated by the server for the user corresponding to the client is encrypted using the encryption key of the group to which the client belongs. The server groups the identifiers of the clients, and the server sends the number of the group and the identifier of the client 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] In step S502, the decryption key associated with the number is obtained as the second decryption key, and the encrypted data is decrypted according to the second decryption key to obtain decrypted data.

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

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

[0119] Referring to Figure 6 , Figure 6 FIG. 5 is a flowchart of a data transmission method according to a fifth embodiment of the present application, which is applied to a server. The data transmission method comprises the following steps.

[0120] In step S601, the client corresponding to the to-be-sent data is determined, and the characteristic parameter of the current data reporting mode of the server is obtained.

[0121] In step S602, the first descriptor parameter corresponding to the characteristic parameter is determined, and the to-be-sent data is encrypted to obtain encrypted data.

[0122] In this embodiment, the execution subject is the server. After a user logs in an account and the server generates data, the data needs to be sent to a target terminal for auditing or storage. The data can be different types of report data such as financial institution accounts, fund settlement data, replacement resource quotas, and repayment of replacement resources. The server configures corresponding clients for different users, and a data distribution device in the server distributes the data generated by different users to the corresponding clients of the users in a distributed manner, so that the clients send the data to the target terminal according to the adaptive data transmission link. The following describes this embodiment in detail by taking a client sending data to a target terminal.

[0123] After the user logs in the server, the server generates to-be-sent data including account, balance, transaction details and the like for business processing. The server encrypts the to-be-sent data to obtain encrypted data. The server sets 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, and if the data reporting mode is mode C, the client needs to send data to the target terminal based on a specified external network. The server obtains the current data reporting mode, generates a descriptor parameter based on the characteristic parameters of the current data reporting mode, and the descriptor parameter is defined as a first descriptor parameter. For example, the current data reporting mode can be determined by the account of the user logging in the server, the attributes of the data table of the to-be-sent data, 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 the characteristic parameters of the current data reporting network, a feature vector is constructed based on the characteristic parameters, and the feature vector is the first descriptor parameter. It can be understood that the first descriptor parameter is used for the data reporting mode of the server.

[0124] In step S603, the first descriptor parameter and the encrypted data are sent to the client, so that the client determines the data sending link of the to-be-sent data based on the stored second descriptor parameters and the first descriptor parameter.

[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 the characteristic parameters of multiple data reporting modes of the server, can determine the second descriptor parameter of each data reporting mode based on the characteristic parameters, and stores 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 specific reference is made to the generation process of the first descriptor parameter described above, which will not be described here.

[0127] After the client obtains the first descriptor parameter, the distance between the first descriptor parameter and each second descriptor parameter is determined. For example, 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] The client calculates the distance between the first descriptor parameter and each second descriptor parameter, determines the minimum distance among the distances, and the first descriptor parameter and the second descriptor parameter corresponding to the minimum distance are the most matched. The device can send 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, the data sending link, and the association relationship between the target terminal sent by the server. After determining the current data reporting mode of the server, the device obtains the association relationship corresponding to the current data reporting mode, and determines the data sending link and the target terminal corresponding to the current data reporting mode based on the association relationship. The data sending link is defined as a target data sending link.

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

[0131] After determining the target data sending link and the target terminal, the client sends the decrypted data to the target terminal according to the target data sending 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 parameter of the current data reporting mode, and sends the first descriptor parameter and the encrypted data to the server. The client determines the current data reporting mode of the server based on the first descriptor parameter and the stored second descriptor parameter, so that the client adapts to the data sending link, and the server does not need to identify and adapt the data sending link, thereby reducing the workload of the server and improving the running stability of the server.

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

[0134] According to the characteristic parameter, each feature point of the current data reporting mode under different scales is constructed;

[0135] According to the preset matrix, a key point is determined among the feature points of the current data reporting mode.

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

[0137] In the embodiment, the server determines the first description parameter of the current data reporting mode based on the characteristic parameter of the current data reporting mode, which is consistent with the generation process of the second description parameter in the second embodiment. For details, refer to the second embodiment, which will not be repeated here.

[0138] In an embodiment, the step of encrypting the to-be-sent data to obtain the encrypted data comprises:

[0139] obtaining the first encryption key corresponding to the current data reporting mode;

[0140] encrypting the to-be-sent data according to the first encryption key to obtain the encrypted data.

[0141] Further, the step of obtaining the first encryption key corresponding to the current data reporting mode comprises:

[0142] determining the first identifier corresponding to the current data reporting mode, and obtaining each different first encryption key associated with the first identifier;

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

[0144] According to the encryption order of each first encryption key, the to-be-sent data is sequentially encrypted to obtain the encrypted data.

[0145] In the embodiment, the server obtains the encryption key based on the current data reporting mode, and encrypts the data. For details, refer to the related description of the decryption of the client based on the decryption key of the current data reporting mode in the third embodiment, which will not be repeated here.

[0146] In an embodiment, the step of encrypting the to-be-sent data to obtain the encrypted data comprises:

[0147] obtaining the second identifier of the client, and determining the number of the group where the second identifier is located;

[0148] obtaining the encryption key associated with the number as a second encryption key, and encrypting the to-be-sent data according to the second encryption key to obtain the encrypted data.

[0149] In the embodiment, the server groups the client, and the number where the group is located determines the encryption password to encrypt the to-be-sent data. For details, refer to the related description of the decryption of the client based on the number of the group in the fourth embodiment, which will not be repeated here.
