[0094] In order to make the technical problems, technical solutions and advantages to be solved by the present invention more clear, a detailed description will be given below with reference to the accompanying drawings and specific embodiments.

[0095] It should be understood that the references to "one embodiment" or "an embodiment" throughout the specification mean that the specific features, structures, or characteristics associated with the embodiment are included in at least one embodiment of the present invention. Therefore, the references to "in one embodiment" or "in an embodiment" appearing throughout the specification do not necessarily refer to the same embodiment. In addition, these specific features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0096] In various embodiments of the present invention, it should be understood that the size of the serial numbers of the following processes does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present invention.

[0097] Additionally, the terms "system" and "network" are often used interchangeably herein.

[0098] In the embodiments provided in the present application, it should be understood that "B corresponding to A" means that B is associated with A, and B can be determined according to A. However, it should also be understood that determining B according to A does not mean determining B only according to A, and B can also be determined according to A and / or other information.

[0099] like Figure 1As shown, a data processing method according to an embodiment of the present invention is applied to a data detection device, comprising:

[0100] Step 101: After obtaining data detection authorization, perform contamination detection on the medical data stored in the cloud database.

[0101] Before the data detection device performs contamination detection on the medical data in the cloud database, it needs to obtain data detection authorization, which is obtained by the data detection device from the data acquisition device. The data acquisition device is the data owner. For example, for medical data, the data acquisition device can be a detection device in a hospital that can directly obtain the patient's medical data, or an application that can view medical results.

[0102] The medical data stored in the cloud database is sent by the data acquisition device. The data acquisition device initializes the data, processes the medical data into a vector model, and encrypts the data vector using symmetric encryption, with the key K; the data acquisition device transmits the encrypted data vector to the cloud database for storage. In this embodiment, due to the sensitivity of medical data, it cannot be uploaded directly to the blockchain and needs to be encrypted before uploading. The encrypted data will be very large, and publishing all the encrypted data information to the blockchain will result in low storage efficiency. The present application stores the medical data in the cloud database and performs pollution detection on the cloud database end, which has higher data storage efficiency. The present application adopts a distributed storage method, and the data information itself is encrypted and stored in the cloud database, while information such as URL can be stored on the blockchain platform, which improves data storage efficiency.

[0103] Step 102: According to the result of the pollution detection, the polluted data is processed and corresponding pollution processing opinion information is generated.

[0104] After obtaining the detection authorization from the data acquisition device, the data detection device accesses the cloud database, performs contamination detection on the medical data stored in the cloud database, finds and processes the contaminated data, and generates corresponding contamination processing opinions based on the processing process of the contaminated data.

[0105] Step 103: Send the pollution treatment opinion information to the blockchain platform so that the blockchain platform shares the pollution treatment opinion.

[0106] For medical data, after the data detection device processes the contaminated data and generates contamination treatment opinion information, the contamination treatment opinion information is sent to the blockchain platform. Multiple medical data sharing parties can view the contamination treatment opinion in the blockchain platform, so that they can refer to the contamination treatment opinion for data processing. In the blockchain platform, through the sharing of contamination treatment opinions, for example, multi-party consultation can be achieved. The blockchain platform records the contamination treatment opinion information in the smart contract, and uses the code in the smart contract to optimize the multiple contamination treatment opinions uploaded by multiple data detection devices to obtain the optimal processing result. In the blockchain platform, the data sharing party can view the optimal processing solution for such contaminated data, so that the contaminated data can be processed according to the optimal processing solution; in addition, the contamination treatment opinion is uploaded to the blockchain platform, and the content in the blockchain platform cannot be tampered with or denied, so the embodiment of the present application can further ensure the reliability and practicality of the data.

[0107] In an embodiment of the present invention, after the data detection device obtains the detection authorization, it performs pollution detection on the medical data stored in the cloud database, processes the polluted data and generates corresponding pollution treatment opinions, and uploads the pollution treatment opinions to the blockchain platform, thereby further realizing multi-party sharing of medical data pollution treatment and obtaining more reliable data processing opinions; storing the medical data in the cloud database and implementing pollution treatment in the database can avoid the situation where the contaminated data cannot be modified due to direct encryption of the data on the chain, thereby optimizing data pollution management and ensuring data reliability.

[0108] It should be noted that the medical data in the cloud database is sent by the data acquisition device, which is the owner of the data. Before the data acquisition device transmits the medical data to the cloud database, the cloud database needs to be registered with the data acquisition device. Taking the cloud database S and the data acquisition device H as an example, the cloud database S generates a digital signature Sig(S||TS) with its identity information S and timestamp TS, and the cloud database sends its own identity information, timestamp and signature "S||TS||Sig(S||TS)" to the data acquisition device; after receiving the message from the cloud database, the data acquisition device H first verifies the validity of the timestamp and signature. If the signature is valid, the data acquisition device H generates a signature "Sig(H||TS1||C)" based on its own identity information H, timestamp TS1 and encrypted data vector C, and then transmits the encrypted data vector C, identity information H, timestamp TS1 and signature formed information "C||H||TS1||Sig(H||TS1||C)" to the cloud database, so that the data acquisition device can transmit the data to the cloud database.

[0109] Optionally, before performing contamination detection on the medical data stored in the cloud database, the method further includes:

[0110] Sending first verification information to a data acquisition device; receiving second verification information generated by the data acquisition device when the first verification information is successfully verified, wherein the second verification information includes a data detection authorization file; and determining that data detection authorization is obtained when the data authorization file is received.

[0111] Optionally, the second verification information also includes: identity information of the data acquisition device, a timestamp, and signature information generated based on the identity information and the timestamp; before performing contamination detection on the medical data stored in the cloud database, the method also includes: verifying the validity of the timestamp and the signature information; the performing contamination detection on the medical data stored in the cloud database includes: performing contamination detection on the medical data stored in the cloud database when the timestamp and the signature information are valid.

[0112] This embodiment is a process for a data detection device to obtain data detection authorization. Before performing contamination detection on medical data in a database, it is necessary to first obtain data detection authorization from a data acquisition device. Taking data detection device A and data acquisition device H as an example, data detection device A generates a digital signature Sig(A||TS3) using its own identity information A and timestamp TS3, and sends the identity information A, timestamp TS3 and signature "A||TS3||Sig(A||TS3)" to data acquisition device H; "A||TS3||Sig(A||TS3)" here is the first verification information. After receiving the information sent by the data detection device, the data acquisition device H first verifies the validity of the timestamp and the signature. If the signature is valid, the data acquisition device H generates an authorization certificate (cert), that is, the data detection authorization file, and uses cert with its identity information H, timestamp TS4, and symmetric encryption key K to generate a digital signature Sig (cert||H||TS4||K). The data acquisition device H sends the information "cert||H||TS4||K||Sig(cert||H||TS4||K)" formed by the data detection authorization file, identity information H, timestamp TS4, key K and signature to the data detection device A. Here, "cert||H||TS4||K||Sig(cert||H||TS4||K)" is the second verification information. After receiving the information sent by the data acquisition device H, the data detection device A first verifies the validity of the timestamp and the signature. If the signature is valid, it is considered that the authorization for data detection is obtained, and the data detection device will hold the data detection authorization file cert to perform pollution detection on the data in the cloud database.

[0113] Optionally, the contamination detection of medical data stored in the cloud database includes: using a symmetric key to decrypt the medical data vector stored in the cloud database to obtain a data vector; establishing a Gaussian distribution model based on the data vector; using the Gaussian distribution model to obtain a probability density function value; and determining whether the medical data stored in the cloud database is contaminated based on the probability density function value and a first target value corresponding to the probability density function value.

[0114] In this embodiment, considering that some data information (such as medical data) is sensitive and the data volume is large, it is inappropriate to upload the data to the blockchain, so it still needs to be stored in the cloud database. Since the cloud database is "semi-honest", there will be some data pollution problems caused by human or its own mistakes, so it is necessary to detect the data pollution, find the polluted data and modify or delete it. Data pollution detection can be achieved through the Gaussian model. The following describes the process of the data detection device performing data pollution detection on medical data through the multivariate Gaussian model.

[0115] (1) The data detection device A decrypts the encrypted data vector C using the symmetric key K to obtain the complete data vector model;

[0116] (2) A multivariate Gaussian distribution model is established based on the data vector model, and its density function is:

[0117]

[0118] Where p is the density function, M is an n*n dimensional matrix, x is a data vector, and μ is a random vector;

[0119] (3) According to the data vector, the data detection device first calculates the random vector:

[0120]

[0121] m is the number of data vectors x, i=1, 2…m.

[0122] (4) The data detection device calculates the matrix:

[0123]

[0124] (5) For the detected data vector x′, calculate according to μ and M:

[0125]

[0126] A first target value is determined according to the relevant numerical value. The first target value may be an empirical value ε. The ε that maximizes the evaluation index (such as F-measure) on the validation set may be selected. When p(x′)<ε, the detected data is considered to be contaminated.

[0127] Optionally, the processing of the contaminated data according to the result of the contamination detection includes: correcting or deleting the contaminated data according to a second target value corresponding to the contaminated data.

[0128] After each data detection device A obtains the contaminated medical data, it corrects the contaminated data according to a predetermined second target value (such as an authoritatively recognized expert database) (for example, fasting blood sugar greater than 7.0 is diabetes, and a contamination value of 5.0 is recorded as diabetes, which is obviously wrong, and can be directly corrected to no diabetes) or deletes the data, such as deleting data with uncertain standards.

[0129] After each data detection device processes the pollution data, it needs to upload the generated pollution treatment opinion information to the blockchain platform. The blockchain platform can share the pollution treatment opinion with all data sharing parties, so that each data sharing party can learn from and obtain a more reliable data processing solution; the blockchain platform records the uploaded pollution treatment opinions on the smart contract, classifies all treatment opinions, triggers the code in the smart contract to vote, and can obtain the optimal pollution control result. The transaction is recorded in the blockchain platform, and the data sharing party can obtain the optimal treatment solution for data pollution, thereby ensuring the reliability of the data; the pollution treatment opinions are published on the blockchain platform, and the information content in the blockchain platform cannot be modified, which can prevent denial or malicious tampering.

[0130] The data detection device, data acquisition device, blockchain platform and cloud database of the present invention form a data detection process such as Figure 2 As shown:

[0131] Among them, the data acquisition device 21 is the data owner, responsible for acquiring medical data, initializing the medical data, and encrypting the data and sending it to the cloud database 22;

[0132] The cloud database 22 is used to store the medical data sent by the data acquisition device. The cloud database 22 needs to obtain authorization from the data acquisition device 21 to acquire the medical data and is responsible for storing the medical data.

[0133] The data detection device 23 is used to perform pollution detection on the medical data stored in the cloud database 22, find the polluted data according to the pollution detection result, process the polluted data and generate pollution processing opinion information, and send the pollution processing opinion information to the blockchain platform 24 so that the blockchain platform 24 shares the pollution processing opinion;

[0134] The blockchain platform 24 can be integrated in the data acquisition device or can be a separate blockchain carrier, which is used to receive the pollution treatment opinion information sent by the data detection device 23, and share the pollution treatment opinion information with the medical data sharing party; publish the pollution treatment opinion to the smart contract of the blockchain, share the data pollution treatment opinion, and trigger the code in the smart contract at the same time, obtain the optimal data processing result according to the pollution treatment opinion information, and publish the optimal data processing result to the blockchain.

[0135] In the embodiment of the present invention, after the data detection device obtains the detection authorization, by performing pollution detection on the data stored in the cloud database, processing the polluted data and generating corresponding pollution treatment opinions, and uploading the pollution treatment opinions to the blockchain platform, it is possible to further realize the multi-party sharing of medical data pollution treatment and obtain more reliable data treatment opinions; storing the medical data in the cloud database and implementing pollution treatment in the database can avoid the data being directly encrypted and uploaded to the chain, resulting in the polluted data being unable to be modified, and achieve the optimization of data pollution management, thereby ensuring the reliability of the data. After the data detection device processes the polluted data and generates pollution treatment opinion information, the pollution treatment opinion information is sent to the blockchain platform, so that the blockchain platform records the pollution treatment opinion information in the smart contract, shares the data pollution treatment opinions, and uses the code in the smart contract to optimize the multiple pollution treatment opinions uploaded by multiple data detection devices, so as to obtain the optimal processing result, thereby providing the sharing of pollution data treatment opinions, and cannot be tampered with or denied, and can further ensure the reliability and practicality of the data.

[0136] like Figure 3 As shown, a data processing method according to an embodiment of the present invention is applied to a blockchain platform, comprising:

[0137] Step 301: Receive pollution treatment advice information sent by a data detection device.

[0138] After obtaining the detection authorization from the data acquisition device, the data detection device performs contamination detection on the medical data stored in the cloud database, processes the contaminated data according to the results of the pollution detection and generates corresponding pollution processing opinion information; the data detection device sends the pollution processing opinion information to the blockchain platform to realize the sharing of data pollution processing opinions.

[0139] Step 302: Share the pollution treatment opinion information with the medical data sharing party.

[0140] After receiving the pollution treatment opinion information, the blockchain platform can open access rights to all data sharing parties. Multiple medical data sharing parties can view the pollution treatment opinion in the blockchain platform, so that they can refer to the pollution treatment opinion for data processing. In the blockchain platform, by sharing pollution treatment opinions, for example, multi-party consultation can be achieved.

[0141] Step 303: Obtain an optimal data processing result based on the pollution treatment opinion information.

[0142] The blockchain platform optimizes the multiple pollution treatment opinions uploaded by multiple data detection devices to obtain the optimal data processing results. In the blockchain platform, the data sharing party can view the optimal treatment plan for such pollution data, so that the pollution data can be processed according to the optimal treatment plan, which provides the sharing of pollution data processing opinions; the pollution treatment opinions are uploaded to the blockchain platform, and the content in the blockchain platform cannot be tampered with or denied, so the reliability and practicality of the data can be further guaranteed. It should be noted that the execution order of step 302 and step 303 is not limited here, and the blockchain platform can realize the sharing of pollution treatment opinions and the calculation of the optimal treatment results simultaneously or separately.

[0143] Specifically, obtaining the optimal data processing result based on the pollution treatment opinion information may include: recording the pollution treatment opinion information in a smart contract on a blockchain platform; and voting on all the pollution treatment opinion information on the smart contract to obtain the optimal data processing result.

[0144] The blockchain platform receives the pollution treatment opinion information, records the pollution treatment opinion information in the smart contract, shares the data pollution treatment opinion, and triggers the code on the smart contract to vote on all data pollution treatment opinions on the smart contract to obtain the optimal treatment result.

[0145] This application provides for sharing opinions on the processing of polluted data. Due to the diversity and uncertainty of opinions on data pollution management, this application uses blockchain technology to trigger the code in the smart contract to obtain the optimal pollution treatment result, and upload the optimal solution to the chain, thereby optimizing data pollution management.

[0146] It should be noted that the data processing method applied to the blockchain platform provided in the embodiment of the present application can implement all the steps implemented by the blockchain platform in the data processing method applied to the data detection device mentioned above, which will not be repeated here.
