Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of and not restrictive on the broad application.
The data verification method based on the block chain provided by the embodiment of the application can be applied to the application environment shown in fig. 1. Wherein the terminal 102 communicates with the server 104 via a network. The data storage system may store data that the server 104 needs to process. The data storage system may be integrated on the server 104 or may be placed on the cloud or other network server. The server responds to a starting request initiated by a third-party object, generates a login interface, acquires user information input by a user on the login interface, and verifies the user information according to a preset user database to obtain a verification result; and under the condition that the verification result is that the verification is passed, receiving the backup file uploaded by the terminal, carrying out fragmentation processing on the backup file to obtain a plurality of backup file blocks, and verifying the configuration information on the block chain according to the plurality of backup file blocks to obtain a verification result, wherein the configuration information is obtained by configuring the configuration file blocks stored on the block chain, and the plurality of configuration file blocks form the configuration file. The terminal 102 may be, but not limited to, various personal computers, notebook computers, smart phones, tablet computers, internet of things devices, and portable wearable devices, and the internet of things devices may be smart speakers, smart televisions, smart air conditioners, smart car-mounted devices, and the like. The portable wearable device can be a smart watch, a smart bracelet, a head-mounted device, and the like. The server 104 may be implemented as a stand-alone server or as a server cluster comprised of multiple servers.
In one embodiment, as shown in fig. 2, a block chain-based data verification method is provided, which is described by taking the method as an example applied to the server 104 in fig. 1, and includes the following steps:
The third-party object may refer to an object that does not belong to the terminal or the server, but may be an object obtained when the terminal or the server executes the program. Such as the third party object may be a script, an auxiliary APP, etc.
For example, a start button on a script stored in the terminal may be clicked, the script initiates a start request to the server according to the click of the user, and the server generates a login interface after receiving the start request.
Bat, in order to start the initial check of the backup file under D disk, and initiate the start request to the server, after the server receives the start request, produce the login interface, the user can input the user information related to oneself on the login interface.
And step 204, acquiring the user information input in the login interface, and verifying the user information according to a preset user database to obtain a verification result.
The user information may refer to information for characterizing the identity of the user, and the user information has uniqueness and legality. The user information may include account information and a login password, and the account information may be an identification card number, a job number, a mobile phone number, and the like of the user.
The user database may refer to a database that is stored in advance for validity verification of user information. The user database may be pre-stored in the server, or may be stored in other service clusters, and the user database may store a plurality of pre-set user information.
Illustratively, after a user fills user information in a login interface, the server acquires the user information filled by the user, and verifies the legality and authenticity of the user information according to a user database to obtain a verification result.
For example, when the user information includes account information and a login password, the account information and the login password stored in the server user database verify the account information and the login password filled by the user to obtain a verification result. If and only if the account information and the login password filled by the user are consistent with the account information and the login password stored in the user database, the verification is passed, and the main interface is skipped; and when the account information and the login password filled by the user are inconsistent with the account information and the login password stored in the user database, the user is refused to login.
And step 206, receiving the backup file uploaded by the terminal under the condition that the verification result is that the terminal passes the verification.
Among them, the backup file may refer to a file for preventing falsification, which is stored in advance in a legitimate terminal. The backup file may be a file of a certain version of the information management system, or may be a file including multiple versions of the information management system.
Illustratively, when the verification result is that the verification is passed, the user is a legal user, and at this time, the backup file uploaded by the user is received.
For example, after the user successfully logs in, the user may go to the blockchain management interface, and select the backup file to upload in the blockchain management interface. The terminal can upload the backup file selected by the user to the server through the TCP protocol and the IP protocol.
And step 208, carrying out fragmentation processing on the backup file to obtain a plurality of backup file blocks.
The backup file block may refer to a fragment file of the backup file.
For example, when the backup file is a program file of a certain version of the information management system, the program file may be divided into smaller segments, resulting in a plurality of backup file blocks.
The backup files are segmented to obtain a plurality of backup file blocks, so that all the persons except the content owner can not view or access the backup file blocks, and the safety of the files is improved.
In some embodiments, the fragmentation may be based on the data type of the program in the backed-up file and the application of the backed-up file.
Wherein a configuration file may refer to a file stored on a blockchain. Such as the configuration file may be a file of versions of the information management system previously stored on the blockchain. The configuration file is also stored in the form of configuration file blocks on the blockchain, and the configuration file blocks are distributed on a plurality of nodes of the blockchain to prevent the configuration file blocks from being maliciously tampered.
The configuration information may refer to information obtained by configuring on the blockchain according to a configuration file.
Exemplarily, the configuration information on the blockchain is checked according to a plurality of backup files to obtain a check result, so as to check whether the configuration file is tampered, thereby improving the security of the file.
According to the data verification method based on the block chain, the backup file blocks are obtained by carrying out fragmentation processing on the backup files, the configuration information on the block chain is verified according to the plurality of backup file blocks, and the verification result is obtained, so that the judgment of whether the configuration files on the block chain are tampered is realized, and the safety of the configuration files on the block chain is improved.
Referring to fig. 3, in some embodiments, the configuration information includes a plurality of configuration hash values, and step 210 includes, but is not limited to, the following steps:
The configuration hash value may be a hash value obtained by hashing the configuration file. Each configuration hash value may be obtained by hashing a configuration file block, and the configuration hash value has uniqueness.
The backup hash value may refer to a hash value obtained by hashing the backup file block. The backup hash value is also unique.
Illustratively, the backup file blocks are subjected to hash processing, so as to obtain backup hash values corresponding to the backup file blocks.
And 304, comparing the configured hash values on the block chain according to the backup hash value to obtain a verification result.
For example, the backup hash value and the configuration hash value may be compared, and whether the backup hash value and the configuration hash value are the same or not may be determined to obtain the check result.
According to the technical scheme, the configuration hash value and the backup hash value are compared to judge whether the configuration hash value and the backup hash value are consistent, so that verification of the configuration file is achieved, and the safety of the file is improved.
In some embodiments, step 304 includes, but is not limited to, the following steps: judging whether the backup hash values corresponding to the backup file blocks are equal to the configured hash values at the same positions on the block chain; if yes, obtaining a first verification result representing that the verification is passed; if not, a second checking result which represents that the checking fails is obtained.
Specifically, in this embodiment, since the backup file and the configuration file are both fragmented into a plurality of file chunks, the configuration file is verified by comparing whether the hash values corresponding to each file chunk are equal to each other.
According to the technical scheme of the real-time exchange rate, the backup hash values corresponding to the backup file blocks are compared with the configuration hash values corresponding to the configuration file blocks one by one, so that whether the configuration file blocks are tampered or not is conveniently determined, the tampered configuration file blocks are conveniently positioned, and the tampered files are conveniently recovered subsequently.
In some embodiments, the blockchain-based data verification method further includes, but is not limited to, the steps of: when the verification result is a second verification result representing that the verification is not passed, acquiring a configuration file block corresponding to the backup hash value and the configuration hash value which are not equal; and marking the configuration file block as a tampering file, and acquiring address information corresponding to the tampering file based on the blockchain.
The address information may refer to IP address information, and after the user logs in successfully, the server records the IP address of each user.
Specifically, when the verification fails, it is indicated that the configuration file and the backup file are different, in this case, the configuration file may be maliciously tampered, or the backup file may be selected by mistake, and since the backup file is preliminarily checked, it can be considered that the configuration file is maliciously tampered at this time. At this time, the configuration file block corresponding to the backup hash value and the configuration hash value is not equal is obtained, and the configuration file block is marked as a tampered file. And then, acquiring address information corresponding to the tampered file through the record of the server based on the block chain, so as to trace the malicious tampered user and recover the configuration file.
Referring to fig. 4, in some embodiments, the method for checking data based on block chains further includes, but is not limited to, the following steps:
The access request may refer to a request initiated by a user on a terminal for accessing a server. The access request carries information needed by the user.
Illustratively, the user triggers a preset button on the terminal, and the terminal sends an access request to the terminal in response to the triggering request.
And step 404, extracting target information from the verification result according to the access request.
The target information may refer to information that a user needs to obtain. For example, the information may be a detailed description of hash processing or a detailed description of a configuration file.
Illustratively, the server may extract the target information from the verification result according to the access request.
In some embodiments, when the configuration file is an information management system, the operation description of the information management system, such as an operated video tutorial, an operated picture tutorial, and the like, may also be obtained according to the access request, and the tutorials are issued to the terminal.
And step 406, sending the target information to the terminal.
After the target information is obtained, the server can send the target information to the terminal through communication modes such as a network and the like.
In some embodiments, the blockchain-based data verification method further includes, but is not limited to, the steps of: and copying each backup file block, and distributing the copied backup file blocks to each node of the block chain to update the configuration file.
Specifically, the backup file blocks may be copied, and the copied backup file blocks may be distributed to each node of the block chain, so as to update the configuration file and recover the tampered configuration file blocks, thereby facilitating improvement of file security.
It should be noted that, during copying, a threshold may be set to ensure that there are enough redundant copies to ensure the availability and performance of the backup file, prevent the loss of the backup file, and improve the security of the file.
In some embodiments, a reliable environment may also be established by the dispersal of the blockchain and hashing the scrambled biosystems. The blockchain actively ensures that fraud is prevented safely and any user of an organization cannot violate compliance, thereby facilitating the improvement of the security of the file and preventing the configuration file from being tampered maliciously.
It should be understood that, although the steps in the flowcharts related to the embodiments are shown in sequence as indicated by the arrows, the steps are not necessarily executed in sequence as indicated by the arrows. The steps are not performed in the exact order shown and described, and may be performed in other orders, unless explicitly stated otherwise.
