Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, exemplary embodiments according to the present invention will be described in detail below with reference to the accompanying drawings. It is to be understood that the described embodiments are merely a subset of embodiments of the invention and not all embodiments of the invention, with the understanding that the invention is not limited to the example embodiments described herein. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the invention described herein without inventive step, shall fall within the scope of protection of the invention.
Currently, a complete infectious disease monitoring, early warning and decision-making assisting system is established, and management of disease control data is mainly divided into the following four stages:
the first stage is as follows: when reporting collected data, a general practice of medical institutions and the like is to report all data of all patients, which usually includes personal attribute data, health condition data, medical application data and the like.
And a second stage: and performing multi-source heterogeneous cooperative scheduling on the reported data to realize centralized collection, and performing data standardization processing. Because the field formats, description modes and the like of data reported by different channels are inconsistent, invalid information needs to be removed first, and then the valid information is subjected to standardized processing according to a standard format. The data includes personal privacy information, and it is a common practice for the personal privacy information to be encrypted, for example, to display a "name: wang, identification number: * Or encrypted in a database and decrypted when needed.
And a third stage: and (3) performing infectious disease analysis and generating early warning signals based on the data structuring and semantic understanding analysis capability and the three-interval distribution.
A fourth stage: and carrying out response processing on the generated early warning signal.
The above method for managing the disease control data has the following disadvantages:
(1) The large amount of private data involved in this process may lead to concerns about data security or low willingness of the medical institution to share data.
(2) In the existing scheme, even if the private data is encrypted for display or encrypted for storage, the risk of private data disclosure still exists, for example, the private data is acquired by brute force search or thorough key search brute force cracking, or a centralized server is attacked to acquire a key.
Accordingly, to solve the above-mentioned problems of the existing disease control data management, the present invention provides a method for managing disease control data, the method comprising: classifying the collected disease control data of the individual into privacy data and business data; acquiring identification data for uniquely identifying an individual, and sending the identification data and service data of the individual to a centralized server for storage; and providing the private data to the requestor in response to a request for access to the private data by the requestor.
According to the method for managing the disease control data, the personal privacy data are stored in a distributed mode, less personal privacy data can participate in centralized storage and data circulation, and therefore safety of the personal privacy data can be effectively guaranteed.
The method and apparatus for managing disease control data according to the present invention will be described in detail below with reference to specific embodiments.
Referring initially to FIG. 1, FIG. 1 illustrates a flowchart of exemplary steps for a method 100 for managing disease control data, according to one embodiment of the present invention. As shown in FIG. 1, a method 100 for managing disease control data may include the steps of:
in step S110, the collected disease control data of the individual is classified into privacy data (referred to as B) and business data (referred to as C); and
in step S120, identification data for uniquely identifying an individual is acquired, and the identification data and business data of the individual are transmitted to a centralized server for storage.
In step S130, the private data is provided to the requester in response to an access request for the private data by the requester.
In one embodiment, the method 100 for managing disease control data of the present invention can be implemented using a smart contract-based blockchain platform. The invention utilizes the block chain platform to manage the disease control data, and does not completely report all data at the beginning of reporting, thereby realizing distributed storage of the personal health medical data, only calling the related personal privacy data when needed, and effectively ensuring the safety of the personal privacy data.
In one embodiment, to implement a hierarchical process of personal health medical data, collected disease control data of an individual may be classified into private data and business data. The private data refers to data that can be used to identify an individual, and may include data such as an individual's name, identification card number, medical insurance card number, birth date, contact phone number, work unit, and detailed address. The business data refers to basic data required by disease control early warning, and can include data such as age, country, disease date, chief complaint/present disease history/past history, examination report, doctor diagnosis, medicine purchase, reporting unit, reporting date and the like. After the personal health medical data are classified, the data belonging to the business data can be determined to be reported at the beginning of reporting according to the category of the data, and the data belonging to the privacy data are not reported at the beginning of reporting but are locally stored.
The necessary conditions for generating the disease control early warning signal are time, space and crowd, and for crowd data, the identity of a patient is not necessarily completely clear at the beginning of data reporting, and only one unique identifier needs to be provided to identify data attribution and analyze and summarize the data reported by each channel.
In one embodiment, obtaining the identification data may include: and acquiring data from the privacy data as identification data, for example, selecting an identification number as identification data. In one embodiment, the identification data may not be selected from the privacy data, but may be additionally provided (for example, individually or in combination with numbers, characters, etc.) as long as it uniquely identifies the individual, which is not limited by the present invention.
In one embodiment, obtaining the identification data may include: the method includes acquiring and encrypting data from the privacy data to be used as identification data, for example, selecting and encrypting data (e.g., an identification number, a medical insurance card number, etc.) from the privacy data to be used as identification data.
In one embodiment, the selected data may be encrypted using encryption techniques in the blockchain, such as using SHA256, SM3, or SM4 encryption that is not easily hacked. We call the original data A (plaintext) and the encrypted data f (A) (ciphertext). And f (A) is adopted to realize the identification of the main body to which the data belongs and the subsequent data stream transfer, thereby avoiding the disclosure of personal identity and privacy information to the maximum extent. When the main body consistency judgment is needed to be carried out on the data reported by different channels, the consistency judgment of the main body to which the data belongs can be realized only by carrying out the consistency comparison of f (A), thereby achieving the purpose of integrating the data. For example, a patient A is treated in a first hospital and a second hospital respectively, both hospitals report data, and the data reported by the two hospitals are judged to be consistent by comparing f (A), so that the repeatability of source data is ensured.
At the beginning of reporting data, only the identification data and the business data of the individual are sent to a centralized server (for example, located at a disease control center) for storage, and the private data of the individual are not sent to the centralized server for storage, but are locally stored, namely stored at a medical institution collecting the private data, so that the data can not be discharged.
In one embodiment, when storing private data of a person locally, the method 100 may further include: and encrypting the private data by using the local key and storing the private data locally. Where the local key is maintained by the medical institution itself. In one embodiment, the private data is encrypted using symmetric encryption, such as encryption using AES (advanced encryption Standard) or the like.
In one embodiment, the method 100 may further include: before the identification data and the service data are sent to the centralized server, the identification data and the service data are encrypted and signed, and then the identification data and the service data are sent to the centralized server so as to participate in the subsequent service flow and data circulation process. In one embodiment, the identification data and the service data can be cryptographically signed by using a digital signature technology, so that the data is authentic and trustable at the data source.
Referring to FIG. 2, FIG. 2 illustrates a schematic diagram of distributed storage of disease control data, according to one embodiment of the invention. As shown in fig. 2, data a and privacy data B that can identify an individual identity are encrypted and stored in a distributed manner by each medical institution node, and a centralized server node stores only identification data f (a) and service data C required for a disease control early warning.
The encryption and distributed storage of the private data are mainly controlled and executed by a Disease Control data privacy protection Protocol DCAP (Disease Control assertion Protocol) based on a block chain. However, since the personal identity information is stored in each medical institution, when the disease control early warning occurs, the corresponding disease control measures must be implemented to the person, and thus the personal identity information needs to be accurately acquired in the prevention and treatment stage. The method for realizing the requirements comprises the steps of realizing hierarchical authorization, local decryption, encrypted transmission and independent signature verification through an intelligent contract.
In one embodiment, the process of obtaining private data of an individual is as follows: a requester requiring access to private data of a patient sends an access request to a medical institution, and in response to the requester requesting access to the private data, the medical institution provides the requested private data to the requester.
In one embodiment, the requestor may be any organization, institution, department, etc. that needs to obtain personal private data of a patient, which sends an access request through its own computing device to the medical institution that maintains the private data.
In one embodiment, the access request may include identification information of the requester, a public key of the public-private key pair, and a directory of data to be obtained, and may also include other information, which is not limited by the invention. The identification information of the requester may be any information for proving the identity of the requester, such as a CA certificate, and the like, which is not limited by the present invention.
In one embodiment, the public-private key pair is used to encrypt data during data transmission, which is randomly generated with each access request, so that each public-private key pair is only used for this access request. This helps to avoid leakage of private data during data transmission, thereby ensuring data security.
In one embodiment, the step S130 of providing the private data to the requester in response to the access request of the requester to the private data may include the steps of:
in step S1320, in response to an access request for the private data by the requester, data to be acquired is extracted;
in step S1340, the extracted data is encrypted with the public key, and the encrypted data is provided to the requester.
In one embodiment, the step S1320 of extracting the data to be acquired in response to the access request of the requester for the private data may include the following steps:
in step S1322, in response to an access request for private data by a requester, the identity of the requester is verified using the identification information, and it is determined whether data to be acquired is within a data authority preset for the requester;
in step S1324, the data to be acquired is extracted in response to the identity of the requester being verified and the data to be acquired being within the preset data authority.
After receiving an access request for private data, the identity of a requester is verified by using identification information contained in the access request, and whether data to be acquired is within a data authority preset for the requester is determined. The method further includes denying access to the private data by the requestor if the authentication of the requestor's identity fails, and denying access to the private data by the requestor if the data to be obtained is not within a data right preset for the requestor. The access request is accepted and the data to be retrieved is extracted only if the identity of the requestor is verified and the data to be retrieved is within the data permissions pre-set for the requestor.
Since the private data stored by the medical institution is encrypted, after the data to be acquired is extracted, the extracted data is first decrypted by using the local key stored by the medical institution, and then the decrypted data is encrypted by using the public key in the access request, and the encrypted data is transmitted to the requester. After receiving the encrypted data, the requester decrypts the encrypted data by using the private key stored by the requester, so as to obtain the requested private data.
Since the public key and the private key are randomly generated for the access request, even if the private data is maliciously obtained in the transmission process, a malicious attacker cannot obtain the private data because the malicious attacker does not have the private key for decryption.
According to the method for managing the disease control data, the individual privacy data are stored in a distributed mode through the block chain technology, less individual privacy data can participate in centralized storage and data circulation, and the privacy data are stored in an encrypted mode through the block chain technology, so that the safety of the individual privacy data can be effectively guaranteed.
The invention also provides a device for managing the disease control data. Referring to FIG. 3, FIG. 3 illustrates a schematic block diagram of an apparatus 300 for managing disease control data, according to an embodiment of the present invention. As shown in FIG. 3, the apparatus 300 for managing disease control data can include a memory 310 and a processor 320, the memory 310 storing a computer program for execution by the processor 320, the computer program, when executed by the processor 320, causing the processor 320 to perform the method 100 for managing disease control data in accordance with embodiments of the present invention as previously described. The detailed operation of the apparatus 300 for managing disease control data according to the embodiments of the present invention can be understood by those skilled in the art in conjunction with the foregoing description, and therefore, for the sake of brevity, will not be described in detail herein.
