Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention.
The invention provides a laboratory management system based on a block chain, which comprises: data transmission, data storage, data sharing and identity authentication.
The data transmission is used for collecting the experimental data, and users with authority can link the experimental data and transmit the experimental data to multiple persons.
Specifically, the data transmission user includes: the system comprises experimenters, analysts and examiners, wherein the experimenters, the analysts and the examiners can be an organization and have independent CA nodes, anchor nodes and main nodes, and the logical topological diagram of the block chain network is shown in the figure 1.
Specifically, referring to fig. 2, the main cooperation process of each organization in data transmission is as follows: the experimental personnel, as an operator of the experiment, collects, summarizes and arranges the experimental data and carries out data chaining; an analyst reads data through the block chain, analyzes experimental data, and synchronously links the new data; the examiner reads data through the block chain, performs examination by combining the data and report analysis, and synchronously links the examination result.
Specifically, the detailed process of data transmission is as follows: an experimenter collects experimental data by operating experimental instrument equipment, logs in a client by using a PKI key of the experimenter, and collects the experimental data, including data and images; the experimental data is stored as a large-capacity file by an edge storage technology, and relevant information including a storage address, file attributes, a hash value and the like is obtained; the analyst analyzes the experimental data, generates an experimental analysis report, packs the analysis data and the large-capacity file, and submits the analysis data and the large-capacity file to the endorsement node; the examiner examines the relevant experimental data and the analysis report to obtain an examination result, and the examination result is packed together with the large-capacity file to submit a proposal of data chaining to the endorsement node; the endorsement node carries out an endorsement task and verifies the validity, and feeds back a result to the client; the client receives the result and submits the result to the sequencing node; the sequencing node carries out a global sequencing task, generates a new block according to rules and submits the new block to the main nodes of experimenters, analysts and examiners; after passing the verification, each node synchronizes and stores the data.
By adopting the embodiment, the experimenter, the analyst and the examiner can share and store the related experimental data. Each user can read the shared data through the client to carry out related work, so that the working efficiency of each organization is improved, and the safety of experimental data is guaranteed.
The data storage is used for storing the experimental data in a decentralized mode, encrypting the experimental data and improving data security.
In an alternative embodiment, the data storage model is multidimensional hashing instead of conventional hashing, and a crossed dual-protection chain is adopted, so that data storage becomes an automatic and non-manual intervention process.
Specifically, referring to fig. 3, after data is collected from instrumentation in a laboratory, original data is automatically packaged and sent to a server for further processing, and a redundant server is backed up; the branched chain server performs hash operation on information such as data to obtain a hash set, the hash set is used for constructing a block chain as branched chains, and all head nodes of all branched chains form a main chain based on multidimensional hash.
In an alternative embodiment, a distributed ledger is designed for storing detailed information related to experiments, including experiment result data, historical experiment records, experiment examination reports and the like, and encrypting the data by asymmetric encryption technology.
By adopting the above embodiment, the double-chain data storage model improves the data security, and ensures that the data of different experiments are separated and do not interfere with each other; secondly, an attacker needs to break through the main chain and the branched chain to obtain data at the same time, and because the data of different experiments are all linked to the main chain, the attacker is more difficult to locate the target data; finally, if an attacker breaks through both chains, they still have to decrypt the data and can only operate on other data if they are still secure.
The data sharing is used for sharing data among users or organizations, and the users can upload data generated by the users to the block chain and can also access data uploaded to the block chain by other users.
Specifically, referring to fig. 4, a data sharing flow is as follows: the user saves the experimental data into a large-capacity file, and the file is encrypted and uploaded to obtain a file hash value and a file pointer; a user saves information such as a file hash value, a file pointer, a file storage address and the like, and writes a formulated access strategy and the information into a block chain account book; after the block chain achieves the consensus, a certificate authority generates a unique token identifier for the accounting node, wherein the token identifier has a system signature and a valid time limit, and all users can approve the token identifier; when a user wants to download data uploaded by the user, the user only needs to decrypt the file by using a private key to obtain a plaintext file; when a user needs to download data uploaded by other users, whether the user meets the access strategy is checked, and if the user meets the access strategy, the file can be decrypted by acquiring a key close to the accounting node or the file owner.
By adopting the embodiment, all users in the system can upload the experimental data, the legality and the safety of the data checked by other users are ensured, and the record and the modification of each time are stored in the block chain, so that the experimental data are real, public, shared and can not be falsified.
The identity authentication is used for identifying the identity information of the user, so that personnel entering a laboratory are ensured to pass the identity authentication, and research and development data are protected from being leaked.
In an optional embodiment, the identity authentication module comprises a data acquisition unit for acquiring face information, fingerprint information and certificate information of a user; the central control unit stores and calls the face information, the fingerprint information and the certificate information of the user; the data processing unit processes and analyzes various data information; and the abnormity alarm unit informs a laboratory manager when the identity information authentication is abnormal.
Specifically, referring to fig. 5, the identity authentication method provided in the embodiment of the present invention includes the following steps:
S1O 1: the user applies for a registration account to the laboratory management system.
S1O 2: the data acquisition unit acquires a plurality of identity characteristic information of the user, at least two different types of identity characteristic information, and at least biological characteristic information and text characteristic information.
S1O 3: integrating a plurality of collected identity characteristic information, integrating the collected identity characteristic information according to classification, and fusing text characteristic information, image characteristic information and biological characteristic information into a biological characteristic model to form the identity information of the user.
S1O 4: encrypting the identity information by using a cryptographic hash algorithm to obtain encrypted identity information, and sending the encrypted identity information to a block chain network; specifically, before the user identity information is encrypted, the biometric information needs to be converted into digital feature information.
S1O 5: when the block chain network receives the user identity information, the identity information is encrypted and stored in a storage database according to an algorithm set by the block chain network, and a unique identification code is generated and returned to the user.
S1O 6: when the identity authentication is carried out, the system acquires corresponding encrypted identity information from the storage database according to the identification code held by the user, decrypts the encrypted identity information to acquire the identity information, and compares and matches the decrypted identity information with the identity information provided by the user.
S1O 7: if the identity information in the storage database is matched with the identity information provided by the user, the authentication is successful; if the matching fails, the user is reminded to use the identity card to carry out identity authentication, and if the matching fails for multiple times, the system informs a laboratory manager.
In summary, the present invention relates to a laboratory management system based on a blockchain, which uses a multidimensional hash algorithm, a distributed storage, a cryptographic hash algorithm, an asymmetric encryption technology, etc. to chain-store, safely transmit and share experimental data, and simultaneously ensure that all personnel entering a laboratory are users authenticated by the system, thereby solving the problems of data safety and collective maintenance existing in the existing laboratory, and ensuring the accuracy, transparency, openness and high efficiency of experimental work.
