Referring to fig. 1, the invention provides a method for modifying text to be checked based on a blockchain, which comprises the following steps:
s1: acquiring a text to be checked from a user node or a service node through a first blockchain node; wherein the first blockchain node and the user node and the service node are nodes in the blockchain;
s2: establishing a visual platform based on the first blockchain node, the user node and the service node; the visual platform stores the text to be checked, and is used for displaying the text to be checked to the first blockchain node, the user node and the service node in real time;
s3: judging whether a modification instruction for modifying the text to be checked is received or not;
s4: if the modification instruction is received, modifying the text to be checked according to the modification instruction;
s5: the change stream based on the mongoDB monitors the text to be checked and records the change position of the text to be checked;
s6: marking the change position of the text to be checked, and recording the mark into the text to be checked;
s7: and sending the modified text to be checked and the mark to each node constructing the visual platform in real time.
The text to be collated is obtained from the user node or service node by the first blockchain node as described in step S1 above. The blockchain is used for setting all users, operators and manuscript checking staff as blockchain nodes to build a blockchain network, and the first blockchain node is the blockchain node where the manuscript checking staff is located, namely, when the manuscript checking staff checks manuscripts, the text to be checked needs to be acquired through the blockchain network, and the text to be checked can be uploaded by the users or the operators. It should be noted that, under the condition that no special processing is performed by other nodes of the blockchain, the text to be checked is not obtained, only the transmission condition of the text to be checked is known, in addition, the first blockchain node is a blockchain node of any manuscript checking person, and after the text to be checked is obtained, the blockchain nodes of other manuscript checking persons cannot obtain the text to be checked.
And as described in the step S2, a visual platform is established based on the first blockchain node, the user node and the service node. Each node constructing the visual platform can modify the text to be checked in real time for each node in the visual platform. The location of the visual platform may be any one of a user node, a first blockchain node and a service node, or may be a temporary virtual blockchain node formed in a blockchain.
As described in the above step S3, it is determined whether a modification instruction for modifying the text to be checked is received. When confirming the text to be checked, whether a modification instruction of the text to be checked is received is needed to be judged, if the modification instruction is not received, the text to be checked can be considered to be qualified (or the text to be checked can be considered to be qualified after the confirmation information of each node is received), and after the text to be checked is qualified, a final text can be formed and uploaded to the system.
As described in step S4, if a modification instruction for modifying the text to be checked is received, modification may be performed according to the corresponding modification instruction. Specifically, each blockchain node constructing the visual platform can be directly modified in the visual platform, namely, a modification instruction is sent out at the corresponding blockchain node, and then the visual platform receives the modification instruction and carries out corresponding modification. Further, in order to prevent two blockchain nodes from modifying the text to be checked at the same time, the modification method can be set in the visual platform, and in a period of time, only one blockchain node has modification authority, and other blockchain nodes can modify the text to be checked after the modification is pushed out by the current blockchain node.
As described in the above steps S5-S6, labeling of the changing position of the text to be checked is achieved, so that each blockchain node constructing the visual platform is convenient for checking the modified text to be checked. The mongoDB is a high-performance, open-source and modeless document type NosQL database, has the advantages of high query speed, high concurrence and high capacity, can be used as a transmission architecture for transmitting the text to be checked, and the change stream is a characteristic of the mongoDB, can be used for supervising the text data change of the text to be checked, and of course can also be used for supervising the text to be checked by other application programs, and has a data pulling mode and an active data pushing mode, so that in a visual platform, each blockchain node can push and pull the text to be checked in the visual platform, thereby realizing real-time change and real-time push of the data, and the change stream also has the characteristic of recording the data change, so that the change position of the text to be checked can be recorded based on the characteristic, namely, the corresponding marking mode is not limited, such as thickening, changing, adjusting a font size, setting a font or a font color, and the like. Therefore, the variable position is marked, and each blockchain node in the visual platform can be visually checked.
And as shown in the step S7, the modified text to be checked and the mark are sent to each node of the visual platform in real time. In order to maintain consistency of texts to be checked of each blockchain node in the visual platform, the modified texts to be checked need to be sent in real time. Specifically, after a modification instruction is seen, the text to be checked is monitored through the change Stream of the mongoDB, once the text data of the text to be checked changes, the changed text to be checked is immediately sent to each node of the visual platform in real time, so that the real-time modification of the text to be checked is realized, and the consistency of the text to be checked of a user, a service person and a manuscript three party is ensured.
In one embodiment, after the step S7 of sending the modified text to be checked and the mark to each node constructing the visual platform in real time, the method further includes:
s801: judging whether acknowledgement information of the user node, the service node and the first block link point is received or not;
s802: and if the confirmation information is received, generating an electronic contract based on the modified text to be checked, and issuing the electronic contract to the visual platform.
As described in the above steps S801 to S802, automatic uploading of the text to be checked is achieved. When each block chain node in the visual platform confirms that the modified text to be checked is correct, namely, the confirmation information of the user node, the service node and the first block chain node is received, an electronic contract can be automatically generated, on one hand, the text to be checked is recorded, and on the other hand, a contract which can be uploaded to a system can be formed according to the text to be checked, so that the service contract can be signed quickly. It should be noted that, since the previous text to be checked is generally written based on the template, the formation mode of forming the corresponding electronic contract according to the text to be checked is the same, and only the corresponding service data is required to be acquired at the corresponding position of the text to be checked, and then the corresponding electronic contract is formed according to the corresponding service data.
In one embodiment, the step S1 of obtaining the text to be checked from the user node or the service node through the first blockchain node includes:
s101: constructing a sub-blockchain according to the user node, the service node and the first blockchain link point based on a sub-blockchain request sent by the user node or the service node to the first blockchain node;
s102: and acquiring the text to be checked from the user node or the service node based on the sub-block chain.
As described in the above steps S101-S102, the selection of the manuscript checking personnel by the user and the business personnel is realized, and the confidentiality of the text to be checked is ensured. The user and business personnel can select a manuscript checking personnel to check, namely, the user node or the business node sends a sub-blockchain request to a first blockchain link point to construct the sub-blockchain request, the transmission of the text to be checked can be carried out only in the sub-blockchain, but the transmission of the text to be checked can not be carried out if the text to be checked is not in the sub-blockchain, and then the text to be checked is acquired based on the sub-blockchain, so that other blockchain link points in the blockchain do not acquire the authority of the text to be checked, the confidentiality of the text to be checked is ensured, and in addition, when the user node and the business node send the sub-blockchain, the corresponding manuscript checking personnel can be selected to check, namely, the sending object of the sub-blockchain request is selected.
In one embodiment, after the step S2 of establishing a visual platform based on the first blockchain node, the user node, and the service node, the method further includes:
s301: judging whether the visual platform sends out data acquisition information or not;
s302: if the data acquisition information is sent out, analyzing the data information to obtain target data to be acquired;
s303: judging whether the target data is in a platform authority range of the visual platform for acquiring data;
s304: if the target data is within the platform authority range, sending the target data to the first blockchain node;
s305: and uploading the target data to the visual platform through the first blockchain node for display.
The acquisition of the target data is achieved as described in the above steps S301-S304. Specifically, in some embodiments, in order to explain the modification reason, or other reasons, to the client and/or the service end, the data in the database needs to be displayed in the visual platform, so that the service end and the client can agree to the modification at the first blockchain node, and therefore, the data acquisition information can be sent out to the blockchain through the visual platform, in some embodiments, the data acquisition information can also be sent out by the user node or the service node, and when the blockchain obtains the data acquisition information, the permission of the visual platform needs to be judged, and in particular, the platform permission should be jointly formed by the permissions of each node in the visual platform, and also can be obtained based on the text to be checked. In order to avoid the leakage of important data, only the data conforming to the platform authority can be uploaded to the visual platform, and related data description can be displayed in the visual platform while the data security in the database is ensured. It should be noted that, the first blockchain node may acquire any data, but may not upload the data at will.
In one embodiment, after the step S305 of uploading the target data to the visual platform for display by the first blockchain node, the method further includes:
s3061: monitoring the time length of sending the target data to the visual platform;
s3062: judging whether the duration exceeds a time preset value or not;
s3063: if yes, deleting the target data from the visual platform.
As described in the above steps S3061-S3063, the data management in the visual platform is implemented, the storage space in the visual platform is released, so that the whole blockchain can be optimized, that is, after the target data is acquired, the data is mainly for explanation, after the explanation, the meaning of the target data in the visual platform is not very great, and the storage space of the blockchain is occupied, so after the time preset value is elapsed, the target data can be considered to be redundant, and when the sent duration exceeds the time preset value, the target data can be deleted from the visual platform, and the storage space of the blockchain is released, so as to reduce the maintenance cost.
In one embodiment, before the step S102 of obtaining the text to be checked from the user node or the service node based on the sub-block chain, the method further includes:
s1101: acquiring a permission sub-requirement in the sub-block chain request;
s1102: establishing a data acquisition contract based on the rights sub-requirement and the rights of the first blockchain node;
s1103: the first blockchain node grants permission to acquire data from the blockchain corresponding database to the first blockchain node based on the data acquisition result.
As described in the above steps S1101-S1103, the authority setting for the data acquisition of the first blockchain is implemented, so that the first blockchain node does not acquire the data of other authorities in the database, thereby ensuring the security of the database. In this embodiment, only the auditor is allowed to obtain the data related to the permission sub-requirement, for example, the text to be audited is related to the pension insurance, and then the auditor is specified to obtain only the content related to the pension insurance in the database, specifically, a data obtaining contract is established, which is established with the permission sub-requirement and the permission of the auditor, and includes the data permission which can be obtained through the first blockchain node, that is, the data content in the database can be obtained, and only the data information related to the data permission can be obtained later, thereby ensuring the confidentiality of other data of the database.
In one embodiment, the modified text to be checked and the mark are sent in real time to each node S5 constructing the visual platform, including:
s511: and sending the modified text to be checked to each node constructing the visual platform based on websocket protocol.
As described in the above step S511, since the websocket protocol can maintain the connection between the client and the server, that is, the connection between the first blockchain node, the user node, and the service node, the text to be checked can be sent to each node constructing the visual platform in real time through the websocket protocol.
In one embodiment, before the step S1 of obtaining the text to be checked from the user node or the service node through the first blockchain node, the method further includes:
s001: acquiring user information U= (U) uploaded by the service node 1 ，u 2 ，…，u i ，…，u n ) The method comprises the steps of carrying out a first treatment on the surface of the Wherein u is i ∈{0,1}；
S002: extracting a p-dimensional vector U from the user information U p ；
S003: selecting a parameter s from the service nodes according to a preset mode, and according to a formula h=u p 2 (U p ∏ i∈[1，n] u i ) s Setting a hash value of a user node; wherein H is the hash value;
s004: and setting the user node for the user according to the hash value, and sending login information corresponding to the user node to the service node.
Establishing user nodes in the blockchain is accomplished as described in steps S001-S004 above. In order to avoid the system breakdown of the blockchain caused by excessive nodes of the blockchain, the preset blockchain only has a first blockchain node and service nodes, when a new user registers, the new user needs to register in the blockchain, and in order to avoid malicious registration of other people, the corresponding service nodes need to apply for the new user, so that the system of the blockchain is maintained.
In step S001, the user information may include other information of the user, such as age, sex, location area, etc., and in order to simplify the user information to facilitate registration, the user information is uploaded by the user information, where the user information only includes two representations of 0 and 1, for example, a boy label is 1, and a girl label is 0.
In step S002, p-dimensional vector U is extracted p The method of (a) may be to randomly select the user information, or extract the important information first to facilitate the subsequent labeling, and the important part of the user information may be marked as 1, while other non-important information is marked as 0, for example, whether the user is an important client, if yes, it is marked as 1, if not, it is marked as 0. Therefore, a part of the important information can be screened, that is, the dimension with the value of 1 is screened, and then the p-dimensional vector is selected from the selected dimension.
In step S003, for the hash value of the user node, a corresponding parameter S is also required to be selected from the service nodes, where the parameter S may be the hash value of the service node, or may be other parameters of other service nodes, so as to mark the user as a client corresponding to the service node, and of course, if migration of the service needs to occur later, only a label needs to be set for the user node, where the service node and the user node are not bound.
In step S004, a user node may be set in the blockchain for the user, after setting, the login information needs to be transferred to the service node so that the service node can acquire and transfer the login information to the user, and the user can log in the blockchain after receiving the login information, wherein the user can change the login information, and the changed login information can be sent to the service node or does not need to be sent to the service node.
