[0067] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0068] Figure 1 The flowchart of the encrypted transmission method of confidential geological data is as follows. In an embodiment of the present invention, an encrypted transmission method of confidential geological data includes:

[0069] Step S100: obtaining boundary information of the surveying and mapping area, constructing a map of the surveying and mapping area according to the boundary information, and obtaining and storing geological data based on the map of the surveying and mapping area;

[0070] Step S200: Slice the survey area map containing geological data to obtain sub-survey units, identify the sub-survey units, and determine risk characteristics and confidence levels;

[0071] Step S300: selecting a sub-surveying and mapping unit as the area to be encrypted according to the confidence level, and encrypting data in the area to be encrypted; wherein the data encryption process is a hierarchical encryption process, and different authorization levels correspond to different encryption ranges;

[0072] Step S400: When receiving a query request input by a user, obtain the user's authority, query the encrypted data according to the user's authority, and feedback to the user.

[0073] The purpose of the technical solution of the present invention is to encrypt the surveyed geological data. The data structure of geological data is a map plus some annotation data. The solution for encrypting geological data in this application adopts a data extraction solution. Data is extracted on the basis of the original data, and the extracted content is used as decrypted data. After the content is extracted, the remaining data is used as encrypted data and fed back to the user. While retaining a certain degree of readability, the decryption process is also very easy. When a decryption request is received, the extracted data is fed back to the user. The above steps are specifically described as follows:

[0074] Before encryption, you first need to determine a surveying and mapping area. The user inputs boundary information to determine a range, and creates a map based on the range, called a surveying and mapping area map, as a surveying and mapping template. When geological data is obtained, the geological data is entered into the surveying and mapping template to obtain a map, called a surveying and mapping area map.

[0075] The surveying and mapping area map is segmented, and the segmentation process requires the use of a grid of preset size. After the surveying and mapping area map is segmented, the sub-maps obtained are called sub-surveying and mapping units. Each sub-surveying and mapping unit is identified to determine whether there is a risk feature in the sub-surveying and mapping unit; the risk feature is an image feature of preset important information; based on the risk feature in the sub-surveying and mapping unit, a parameter can be determined to characterize the risk level of the corresponding sub-surveying and mapping unit, which is called confidence; generally, the confidence of a sub-surveying and mapping unit needs to be comprehensively judged in combination with the risk features of other sub-surveying and mapping units around it.

[0076] Finally, a sub-surveying and mapping unit with a higher confidence level is selected as the area to be encrypted, and data in the area to be encrypted is encrypted. The encryption process adopts a gradient encryption process, and different encryption methods are applied to different authority levels. When a query request input by a user is received, the user authority is obtained, and the encrypted data is queried according to the user authority, and feedback is given to the user. In the technical solution of the present invention, the lower the user authority level, the greater the encryption range, and the less information the user receives from the encrypted data.

[0077] Figure 2 The first sub-process flowchart of the encrypted transmission method of confidential geological data is as follows: the steps of obtaining boundary information of the surveying and mapping area, constructing a surveying and mapping area map according to the boundary information, and obtaining and storing geological data based on the surveying and mapping area map include:

[0078] Step S101: Displaying a map based on a map service, receiving boundary coordinates input by a surveyor, and fitting boundary contours in the map;

[0079] Step S102: opening an adjustment port, receiving adjustment information input by a surveyor, and adjusting the boundary contour; wherein the boundary coordinates and adjustment information may be input by keyboard and mouse or by touch screen;

[0080] Step S103: determining a map template based on the adjusted boundary contour, and acquiring and storing geological mapping data at each moment based on the map template;

[0081] Among them, a region selection port is provided in the map template. When the region selection port receives data, a storage repository corresponding to the region is created to store the region annotation information.

[0082] The above content specifically describes the construction process and application process of the surveying and mapping area map. The map is displayed based on the map service, the boundary coordinates input by the surveyor are received, and the boundary contour is fitted in the map. At the same time, the execution body of this method will also open an adjustment port to receive the adjustment information input by the surveyor and adjust the boundary contour; after the adjustment is completed, the adjusted boundary contour is used as a map template to obtain and store geological surveying and mapping data at various times.

[0083] It should be noted that when acquiring and storing geological data, the uploader often needs to enter some annotation information. Therefore, this application also provides a region selection port. When the region selection port receives data, a storage repository corresponding to the region is created to store the region annotation information. From a usage perspective, this annotation function allows users to delimit a small area and then enter annotations.

[0084] Figure 3 The second sub-flow chart of the encrypted transmission method of confidential geological data is as follows: the steps of dividing the surveying and mapping area map containing geological data to obtain sub-surveying and mapping units, identifying the sub-surveying and mapping units, and determining risk characteristics and their confidence levels include:

[0085] Step S201: receiving risk characteristics selected by the management party, and obtaining mapping images of the risk characteristics under different environmental conditions;

[0086] Step S202: Use the mapping images as samples and the risk features as labels to construct a training set, a test set, and a validation set;

[0087] Step S203: training a neural network model based on the training set, the test set and the validation set;

[0088] Step S204: reading a surveying and mapping area map containing geological data, and dividing the surveying and mapping area map according to a preset grid to obtain sub-surveying and mapping units;

[0089] Step S205: Identify the sub-surveying and mapping units based on the trained neural network model to determine risk characteristics and their confidence levels.

[0090] In an example of the technical solution of the present invention, the risk feature identification process is specifically limited. The principle is that with the help of a neural network model, feature identification is performed on sub-surveying and mapping units with extremely high identification speed and efficiency.

[0091] Steps S201 to S203 in the above content are the model training stage. The risk features are selected by the management party, and the mapping images of the risk features under different environmental conditions are obtained. The mapping images are used as samples (input) and the risk features are used as labels (output) to construct training sets, test sets and validation sets, and then the neural network model is trained.

[0092] In actual application, the surveying and mapping area map containing geological data is read, and the surveying and mapping area map is divided according to the preset grid to obtain sub-surveying and mapping units. The sub-surveying and mapping units are identified based on the trained neural network model to determine the risk characteristics and their confidence levels.

[0093] Specifically, for step S205 in the above content, the step of identifying the sub-surveying and mapping units based on the trained neural network model and determining the risk characteristics and their confidence levels includes:

[0094] The sub-mapping units are input into the trained neural network model to output risk characteristics;

[0095] Obtain risk characteristics of other sub-mapping units around the sub-mapping unit;

[0096] Compare the risk characteristics of the current sub-surveying and mapping unit with the risk characteristics of other sub-surveying and mapping units, and calculate the proportion of similar risk characteristics;

[0097] The proportion is taken as the confidence level;

[0098] The meaning of surrounding is that the distance between two sub-surveying and mapping units is less than a preset threshold.

[0099] The sub-mapping unit is input into the trained neural network model and the risk characteristics are output. On this basis, for a certain sub-mapping unit, the risk characteristics of other sub-mapping units around the sub-mapping unit are obtained, and the risk characteristics of the current sub-mapping unit are compared with the risk characteristics of other sub-mapping units. The number of times the risk characteristics of the current sub-mapping unit appear in its surrounding area is calculated, and the ratio is divided by the total number of surrounding sub-mapping units. The obtained ratio is called confidence. The higher the confidence, the more accurate the risk characteristic. This is because when a certain feature appears in geological data, it appears in a large area. If a certain feature appears in only a small area, it is very likely to be a misjudgment.

[0100] Figure 4 The third sub-flow chart of the encrypted transmission method of confidential geological data is as follows: the sub-surveying and mapping unit is selected according to the confidence level as the area to be encrypted, and the step of encrypting data in the area to be encrypted includes:

[0101] Step S301: when the confidence reaches a preset confidence threshold, the sub-surveying and mapping unit is used as an area to be encrypted;

[0102] Step S302: Determine the data extraction ratio according to the confidence level, take the data extraction ratio as the last term, take zero as the first term, and take the number of types of the preset permission level as the number of terms to construct an arithmetic progression, which is called a ratio progression;

[0103] Step S303: uniformly extracting data from the sub-surveying and mapping units and their corresponding storage repositories based on the proportional series to obtain extracted data corresponding to different authority levels;

[0104] Step S304: using the label of the sub-mapping unit as an index, encrypt and compress the extracted data corresponding to different authority levels into a decryption library.

[0105] All sub-mapping units are traversed, and when the confidence reaches a preset confidence threshold, the sub-mapping unit is regarded as an area to be encrypted, that is, an encryption process needs to be performed on it.

[0106] The technical solution of the present application provides a gradient encryption process. First, a data extraction ratio (maximum value) is determined by the confidence level. Then, an arithmetic progression is constructed based on the data extraction ratio to obtain encryption results of different degrees. The smaller the data extraction ratio, the smaller the encryption effect, which corresponds to a higher authority level. If the authority is high enough, the data extraction ratio is zero.

[0107] Finally, based on the proportional series, data is evenly extracted from the sub-surveying and mapping units and their corresponding storage repositories to obtain the extracted data corresponding to different permission levels. The extracted data are then counted and compressed using the sub-surveying and mapping unit labels as indexes.

[0108] The comprehensive explanation of the above content is: a data extraction ratio is determined by the confidence level, and multiple gradient encryption results are determined by the data extraction ratio, and each encryption result corresponds to an authority level.

[0109] Figure 5 The fourth sub-flow diagram of the encrypted transmission method of confidential geological data is shown in the figure. When receiving a query request input by a user, the steps of obtaining user authority, querying encrypted data according to the user authority, and feeding back to the user include:

[0110] Step S401: receiving a query target input by a user, and obtaining a sub-surveying and mapping unit corresponding to the query target and its label;

[0111] Step S402: Identify the user and obtain user permissions;

[0112] Step S403: Locate the encrypted and compressed data in the decryption library based on the tag, match the data with the corresponding permission level according to the user's permission, and feed back to the user.

[0113] When a query request input by the user is received, the query target input by the user is received, the sub-mapping unit and its label corresponding to the query target are obtained, the user's identity is authenticated, such as face recognition, and his authority is queried; all encryption results in the decryption library are queried according to the label of the sub-mapping unit, and the corresponding encryption results are matched according to the user's authority.
