[0050] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0051] like Figure 1 As shown, the data sharing system based on the whole life cycle of power transmission and transformation project includes data sharing terminal, data verification module, access module and sensitive analysis module;

[0052] The data sharing terminal is used to manage shared data and obtain shared data uploaded by each shared user. Shared users refer to the group that is allowed to upload data or share data during the entire life cycle of the power transmission and transformation project. The corresponding management personnel will perform authorization settings to enable them to have sharing, access and other permissions, and the management personnel will set the sharing requirement definition of each shared user. The sharing requirement definition is used to indicate which range of data the shared user can upload and which range of data the shared user can access; the shared data uploaded by each shared user is verified and processed to obtain the corresponding power transmission and transformation data; the power transmission and transformation data is classified according to the preset storage classification method to obtain each shared classification data; each shared classification data is stored independently, that is, one shared classification data is stored in one storage node;

[0053] An encryption library is established, which is used to store various data encryption algorithms. The encryption library is established using existing technologies. Each shared classified data is encrypted based on the encryption library. Each shared classified data is randomly encrypted according to each data encryption algorithm.

[0054] The method for verifying the shared data uploaded by the shared user includes:

[0055] Establish a permission verification model. The permission verification model is used to perform permission verification on the required data according to the sharing requirement definition of the shared user, to determine whether the required data meets its data range requirements, that is, whether it meets the required permission requirements, and to verify according to the data range corresponding to the uploaded or accessed data, and the uploaded or accessed data is the required data; the expression of the permission verification model is ; Where: s is the requirement data and shared requirement definition; the output data is the permission check value 1 or 0;

[0056] Mark the shared data uploaded by the shared user as demand data, and obtain the shared demand definition corresponding to the shared user; analyze the demand data and shared demand definition through the permission verification model to obtain the corresponding permission verification value;

[0057] For demand data with a permission check value of 1, it indicates that it is not within the upload range of the shared user and cannot be uploaded. If the shared user insists on uploading, the administrator needs to authorize it;

[0058] For the demand data whose permission check value is 0, it indicates that it can be uploaded, and the data that can be uploaded is marked as initial upload data;

[0059] That is, the required data is screened according to the authority verification value to obtain the initial uploaded data; the initial uploaded data is formatted according to a preset format, and the format-converted initial uploaded data is marked as power transmission and transformation data.

[0060] The storage classification method setting method includes:

[0061] Obtain various types of data that may exist in the entire life cycle of the power transmission and transformation project, mark them as unit classes, and determine the data types according to the smallest classification, such as drawings of different objects at each node, related calculation data, etc.;

[0062] Obtain sharing requirement definitions corresponding to each sharing user, classify each unit class according to each sharing requirement definition, and obtain an initial classification corresponding to each sharing user. The initial classification is the unit class corresponding to various data that the sharing user may upload and access;

[0063] Determine the intersection between the initial classifications according to the unit classes corresponding to the initial classifications, that is, the commonly included unit classes, and mark the corresponding intersection as the intersection range; separate the unit classes corresponding to the intersection range from the corresponding initial classification, and mark the separated intersection range as a new initial classification;

[0064] And so on, until there is no intersection between the initial classifications; mark each initial classification as a benchmark classification, and form a classification benchmark method based on each benchmark classification; the management personnel adjust the classification benchmark method according to the storage management needs to obtain the storage classification method; that is, classification can be carried out after the classification benchmark method is obtained, but according to management needs, the management personnel can further subdivide each benchmark classification, but cannot expand the scope of the benchmark classification, that is, the benchmark classification can be divided again, but the scope of the benchmark classification cannot be increased, and the subdivided classification needs to be marked with the corresponding benchmark classification.

[0065] The data verification module is used to perform data consistency verification after the shared user accesses the data, and determine the data verification scope of the shared user. The data verification scope is generally the data accessed by the shared user. However, if the shared user's reputation value is low, all data is used as the data verification scope;

[0066] The backup data corresponding to the data verification range is obtained, and the power transmission and transformation data within the data verification range is verified according to the obtained backup data; the corresponding verification result is obtained; specifically, a corresponding consistency verification model can be established based on the above verification method to determine whether the backup data is consistent with the corresponding power transmission and transformation data; the expression of the consistency verification model is: ; In the formula: q is the input data, i.e. the backup data and the power transmission and transformation data corresponding to the data verification range; the output data is the consistent verification value 1 or 0;

[0067] Calibrate through the consistent calibration model to obtain the corresponding calibration results; perform corresponding processing based on the obtained calibration results.

[0068] Methods for determining the data verification scope of shared users include:

[0069] Get the initial reputation value of the shared user. The value range of the initial reputation value is [60, 100] and is set by the administrator when setting up the shared user.

[0070] Obtain the data security protection record corresponding to the shared user, which is the record data of data protection of the existing configured security protection system during the data access process; analyze the data security protection record to determine the abnormal protection record, that is, compare the data security protection record with the previous and subsequent data security protection records to determine which attacks are caused by the shared user's access, such as the shared user's computer has a virus, and then mark the protection record for protecting its attack as an abnormal protection record; determine the corresponding risk value according to the abnormal protection record, the risk value is set according to the risk type and the protection situation, specifically, first determine the various possible risk types, and set the corresponding initial risk value by professionals according to the risk size of the risk type and whether it is an active operation by the shared user; integrate them into a matching table; match according to the identified risk type to obtain the corresponding initial risk value; then determine whether the protection is successful according to the abnormal protection record, if the protection is successful, the risk value is the initial risk value, if not, the risk value is 100; the risk value range is [0, 100]; the risk value corresponding to each abnormal protection record can also be evaluated based on existing technologies.

[0071] The obtained risk value is marked as FAi, where i represents the corresponding abnormal protection record, i=1, 2, ..., n, and n is a positive integer; the initial credit value is marked as CA;

[0072] According to the formula Calculate the corresponding reputation value;

[0073] Where: XR is the reputation value; CA is the initial reputation value;

[0074] The data verification range is determined based on the obtained reputation value; that is, it is judged based on whether the reputation value is greater than a preset value. If it is greater than the preset value, the data verification range is the shared user access range; otherwise, it is the entire range.

[0075] The access module is used for sharing users to access data, identify the sharing requirement definition corresponding to the sharing user, determine the access scope corresponding to the sharing user according to the sharing requirement definition, and the access scope is composed of corresponding data categories, that is, the sharing category corresponding to each shared classification data; identify the storage node corresponding to each sharing category within the access scope, and mark it as the target node;

[0076] Generate a decryption combination method corresponding to the shared user, that is, generate a corresponding decryption method for decrypting the shared classified data in the target node according to the data encryption algorithm corresponding to each target node, and integrate each decryption method into a decryption combination method;

[0077] The corresponding data access channel is set according to each target node and the decryption combination method, that is, the shared user can only access the data in the corresponding target node according to the data access channel, and decrypt the encrypted shared classified data based on the decryption method corresponding to the data access channel;

[0078] The shared users access the decrypted shared classification data corresponding to each target node according to the data access channel.

[0079] The sensitive analysis module is used to perform sensitivity analysis on the stored power transmission and transformation data, identify the unit class corresponding to each power transmission and transformation data, collect the impact data generated after the corresponding data of each unit class is leaked according to historical data, and mark it as sensitive analysis data, and the sensitive analysis data is composed of each single impact data; analyze each single impact data in the sensitive analysis data to determine the corresponding loss value, and the loss value is converted based on economic loss, such as the loss of reputation and reputation into economic loss, and specifically evaluate it using the existing loss assessment method; identify the stage time corresponding to each single impact data, that is, which stage in the whole life cycle it is in;

[0080] Mark the current time as the benchmark time, and screen each single impact data in the sensitive analysis data according to the benchmark time to obtain each benchmark analysis data; that is, the data corresponding to the benchmark time that cannot be evaluated at the corresponding stage time will be eliminated. For example, some data will have no impact if leaked at this time, but will have an impact if leaked at the previous time. As the stage changes, the degree of impact will also change, such as bidding prices, labor prices, design drawings, etc.; it needs to be determined according to its nature; specifically, professionals will set the impact coefficients of different unit types of data corresponding to different stage times, with no impact, the impact coefficient is 0, and the maximum impact coefficient is 1; an impact coefficient of 1 means that the leakage occurs in the most important period, and the others are gradually reduced according to the changes in the stage time, and are adjusted according to user needs to form an impact coefficient matching table, which is matched according to the stage time and benchmark time of the single impact data; single impact data with an impact coefficient of 0 will be eliminated; it can also be analyzed in combination with neural networks.

[0081] The benchmark analysis data is marked as j, j = 1, 2, ..., m, m is a positive integer; the loss value is marked as SWj; the impact coefficient is marked as δj;

[0082] According to the formula Calculate the corresponding sensitivity value;

[0083] Where: PH is the sensitive value;

[0084] The unit class with a sensitivity value greater than a threshold value X1 is marked as a sensitive class. The threshold value X1 is set by technical personnel in this field according to actual conditions or obtained by simulating a large amount of data, and can also be adjusted according to screening requirements; management personnel perform corresponding protection processing on sensitive classes according to needs, that is, increase their confidentiality operations to avoid data leakage.

[0085] The data sharing method based on the whole life cycle of power transmission and transformation project includes:

[0086] Acquire the shared data uploaded by each shared user, perform verification processing on the shared data, and obtain the corresponding power transmission and transformation data; classify the power transmission and transformation data according to a preset storage classification method to obtain each shared classification data; independently store each shared classification data; and encrypt each shared classification data;
