Detailed Description
Various exemplary embodiments of the present disclosure will now be described in detail with reference to the accompanying drawings. It should be noted that: the relative arrangement of the components and steps, the numerical expressions, and numerical values set forth in these embodiments do not limit the scope of the present disclosure unless specifically stated otherwise.
Meanwhile, it should be understood that the sizes of the respective portions shown in the drawings are not drawn in an actual proportional relationship for the convenience of description.
The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the disclosure, its application, or uses.
Techniques, methods, and apparatus known to those of ordinary skill in the relevant art may not be discussed in detail but are intended to be part of the specification where appropriate.
In all examples shown and discussed herein, any particular value should be construed as merely illustrative, and not limiting. Thus, other examples of the exemplary embodiments may have different values.
It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, further discussion thereof is not required in subsequent figures.
As described above, the inventors of the present disclosure found that the main reason why the authentication of information provided by the related art lacks public trust is that information is stored and provided only personally for the user. Therefore, the method and the device aim to verify the same information by adopting a plurality of nodes in the block chain, and convert single-node storage into full-network node storage, thereby improving the public credibility of the information. For example, the following embodiments may be employed to implement.
Fig. 1 illustrates a flow diagram of some embodiments of an information verification method of the present disclosure.
As shown in fig. 1, the method includes: step 110, receiving transaction information; step 120, acquiring a second picture; step 130, calculating a hash value; step 140, sending transaction information; step 150, generating a first block; and step 160, sending the first block.
In step 110, transaction information sent from the first node is received. The transaction information may include a node number of the first node, transaction time, a URL to be verified, and a hash value of the first picture, where the first picture is obtained by converting a web page to be verified for the first node.
In some embodiments, the user may enter the URL of the web page to be verified at the client node, i.e., the first node. Firstly, the client node obtains corresponding webpage information according to the URL, converts the webpage information into a first picture (for example, a picture file in png format), and performs hash operation on the first picture to generate a corresponding hash value. For example, the screenshot may be directly performed on the web page to be verified, or the entire html of the web page to be verified may be downloaded and then converted into the first picture.
The client node may then generate a transaction ID based on the node number and the transaction time. For example, the transaction ID may consist of a node number of 32 bits, a random number of 64 bits, and a time stamp of 32 bits. The random number may ensure uniqueness of the transaction ID.
Next, the client node may assemble the transaction ID, the hash value of the first picture, and the URL information, and then sign it using the client node's private key to generate the transaction information. The transaction information may include private key signature and public key information of the client node.
In some embodiments, an information verification device may be disposed on the network side to receive the transaction information sent by each node (for example, sent by Http). The information verification apparatus may be, for example, a verification platform formed of a server cluster, and the node may be, for example, a client node provided on the user side.
For example, the verification platform and each client node are both nodes in a blockchain that have equal rights. Each client node has a local ledger that stores all the data in the blockchain. Each client node can also be provided with a data table used for maintaining the corresponding relation of the transaction information generated by the client node which proposes webpage tracing in the transaction process. In this way, the tamper-resistant property of the blockchain can be utilized in combination with a few ideas to improve the credibility of the information.
In some embodiments, a connection between the information verification device and each client node may be established prior to step 110 in the manner of FIG. 2.
Figure 2 illustrates a signaling diagram of some embodiments of establishing a connection between an information authentication device and various client sections.
As shown in fig. 2, in event 201, the client node 21 sends a registration request to the information authentication apparatus 22. For example, the client node 21 may send a registration request including current user information such as a user ID after startup.
At event 202, the information verification device 22 returns the node number of the client node 21 to the client node 21. For example, the information authentication device 22 checks whether the user exists from a local database after receiving the registration request. If the node number exists, the node number of the client node 21 is returned, and if the node number does not exist, a node number is generated for the client node 21 and returned. The node number is maintained by the information verification device 22, and may be 32 bits, for example, and ensure uniqueness.
At event 203, the client node 21, upon receiving the node number, may deposit it to local disk.
At event 204, the client node 21 sends a get node information request to the information verification device 22 to establish a connection with other nodes, such as the client node 23. A plurality of client nodes 23 may be included in the blockchain.
At event 205, the information validation mechanism 22 loads the client node 21's IP address into its maintained list of node information.
And sends the IP addresses of other nodes, such as client node 23, to client node 21 in event 206.
At event 207, the client node 21 obtains the IP address of the other node and may establish a connection with the other node (e.g., client node 23). For example, 100 other nodes may be selected to be connected as surrounding nodes for subsequent information verification and information tracing. If the number of other nodes is not enough to be 100, an attempt can be made to connect all the other nodes.
The connection between the information verification device and each client node in the blockchain can be established through time 201 and 207 in fig. 2, and then the transaction information sent by each client node can be continuously verified through step 120 and 160 in fig. 1.
In step 120, the webpage corresponding to the URL is converted into a second picture. For example, after receiving the transaction message, the information verification device verifies the transaction message according to the public key information of the client node, and then checks whether the node number exists. If the signature is verified and the node number exists, the web page corresponding to the URL may be converted to a second picture in the same manner as the client node.
In step 130, a hash value of the second picture is calculated. Whether the hash value of the first picture is consistent with the hash value of the second picture can be compared, so that whether the webpage information is tampered or not can be judged.
In step 140, the transaction information is sent to one or more other nodes only if the hash value of the first picture matches the hash value of the second picture, so that the one or more other nodes verify the transaction information. In the case where the hash value of the first picture is not consistent with the hash value of the second picture, a verification failure notification may be returned to the first node.
In some embodiments, the information verification device determines whether the transaction information sent by the first node is verified by comparing the hash value of the first picture with the hash value of the second picture. After the verification is passed, the private key of the information verification device is used for signing the transaction information, and then the encrypted transaction information is broadcasted to other nodes in the whole network. The encrypted transaction information includes public key information and private key signature of the information verification device.
In some embodiments, one or more other nodes decrypt the received encrypted transaction information to obtain the URL in the transaction information. One or more other nodes acquire corresponding webpage information according to the URL, convert the webpage information into a third picture, and perform hash operation on the third picture to generate a corresponding hash value. And only under the condition that the hash value of the first picture is consistent with the hash value of the third picture, returning an information verification success response to the information verification device by one or more other nodes to indicate that the webpage information in the webpage to be verified passes the verification of the node. In the case that the hash value of the first picture is inconsistent with the hash value of the third picture, one or more other nodes may return an information verification failure response to the information verification apparatus, so as to indicate that the web page information in the web page to be verified fails to be verified by the node.
For example, one or more other nodes may encrypt the received transaction information using the node's private key to form an information verification success response. The information verification success response may include public key information and a private key signature corresponding to the node.
In some embodiments, the information verification success response may include an identification bit, where a flag bit of 1 indicates that the node passes the transaction information verification, and a flag bit of 0 indicates that the node fails the transaction information verification.
In step 150, in the case that the number of successful responses to information verification returned by one or more other nodes exceeds a first threshold, the transaction information is subjected to blocking processing to generate a first block, and the first block comprises a first picture or a second picture.
In some embodiments, if the number of successful responses to the received information verification exceeds half of the number of all nodes, the transaction information is considered to pass the verification of each node, and the blocking processing is performed. Whether the verification is passed can also be determined by counting whether the sum of the values of the identification bits is greater than half of the number of all nodes. If the transaction is determined not to be verified, transaction invalidation information may be sent to the first node, and the first node may re-enter the URL for verification in response to receiving the transaction invalidation information.
In some embodiments, the first tile in step 150 may be generated in the manner of fig. 3.
FIG. 3 illustrates a flow diagram for some embodiments of step 150 in FIG. 1.
As shown in fig. 3, step 150 includes: step 1501, obtaining the maximum block height; step 1502, determining a target height; and step 1503, generating a first block.
In step 1501, a current maximum block height of the first node and one or more other nodes is obtained. For example, the information verification apparatus may send a broadcast for acquiring the latest block information of the whole network, and each client node queries the local account book after receiving the broadcast message, acquires its maximum block height, and then replies this information to the information verification apparatus. The block height identifies the storage location of the block in the block chain. The maximum block height is the number of blocks connected on the block chain.
In step 1502, the maximum block height with the largest number of receptions is taken as the target height. For example, the information verification apparatus counts the ratio of the received maximum block heights of the client nodes, and sets the block height having the largest ratio as the target height.
In step 1503, the transaction information is subjected to blocking processing according to the target height to generate a first block. For example, the information verifying device packs the transaction information into the first block according to the block rule and the target height. The information verification device may also write the first block to a local ledger and then sign the first block.
In some embodiments, the first tile may include a tile header, transaction information, and metadata. The first block further comprises one of the first image, the second image or the third image. The chunk header may include the chunk height, the hash value of the chunk, and the pre-hash value of the chunk. The pre-hash value of a block is a hash value of a block that is one step shorter than the block height of the current block. The metadata includes the transaction amount of the current tile. The first block may further include a private key signature and public key information of the information verification apparatus.
Through the steps 1501-1503 in fig. 3, it is prevented that some nodes in the block chain maliciously create a block with a block height that is not yet allocated, thereby preventing information from being tampered and improving the information confidence. The first tile may then continue to be broadcast to the network-wide nodes via step 160 of fig. 1.
In step 160, the first block is sent to the first node and one or more other nodes. For example, the broadcast may be broadcast to the network-wide nodes via UDP (User Datagram Protocol).
In some embodiments, in the event that the number of block verification success responses returned by the first node and the one or more other nodes exceeds the second threshold, an agglomeration success message is sent to the first node and the one or more other nodes so that the first node and the one or more other nodes store the first block in response to the agglomeration success message. A block verification success response is that the first node and one or more other nodes return if the leading hash value of the first block is consistent with the hash value of a second block, the second block being a block one level lower in block height than the first block. The above process may be implemented, for example, by the method of fig. 4.
Fig. 4 shows a signaling diagram of further embodiments of the information verification method of the present disclosure.
As shown in fig. 4, at event 401, client nodes of the full network (e.g., client node 21 and client node 23) obtain a second tile that is one level shorter than the tile height of the first tile.
In some embodiments, the client nodes of the whole network use the public key of the information verification device 22 to check the first block, thereby obtaining the first block, and record the block height of the first block.
In some embodiments, if a block in the client node that is one level lower than the block height of the first block does not exist, the block is obtained by surrounding client nodes. The received blocks may then be classified, with the largest number of blocks recorded as second blocks in the local ledger. That is, the first block and the second block are two consecutive blocks in the block chain in the formation order.
At event 402, it is checked whether the pre-hash value in the first chunk and the hash value in the second chunk are consistent. For example, if there is a match, the first block is written to the local ledger, and if there is no match, the first block is discarded.
In event 403, if the judgment result of the client nodes of the whole network in event 402 is identical, a block verification success response is returned to the information verification device 22; if not, a block verification failure response is returned to the information verification device 22.
At event 404, the information authentication device 22 classifies the received responses and determines whether the number of block authentication successful responses is greater than half the number of response messages.
In event 405, if the determination result of the information verifying apparatus 22 in event 404 is yes, an agglomeration success message is sent to the client nodes of the entire network; otherwise, sending a blocking failure message to the client nodes of the whole network.
At event 406, the client nodes of the entire network store the first chunk in response to the blocking success message sent by the information verification device 22, i.e., store the correspondence between the URL to be verified and the transaction ID for later tracing and forensics of the web page information.
Through the events 401 and 406 in fig. 4, it can be ensured that two consecutive block data in the block chain are not tampered, thereby improving the information confidence.
In some embodiments, after the transaction information is stored in the blockchain, the transaction information may also be verified and traced using the method of FIG. 5.
FIG. 5 illustrates a flow diagram of further embodiments of the information verification method of the present disclosure.
As shown in fig. 5, the method may further include: step 510, forwarding a transaction information acquisition request; step 520, receiving transaction information; step 530, determining a target block; and step 540, returning the target block.
In step 510, the transaction information obtaining request sent by the first node is forwarded to one or more other nodes, and the transaction information obtaining request includes a node number and a transaction time.
In some embodiments, when a user wants to trace back information about a completed transaction, a URL to be traced back may be entered at the client node. The client node queries the local storage based on the URL, obtains the transaction ID corresponding to the URL, and sends the transaction ID to the information verification device (e.g., in Http format).
The information verification device can query the local account book according to the transaction ID to obtain a block corresponding to the transaction ID, and broadcasts the transaction ID through the whole network to obtain the block corresponding to the transaction ID in the nodes of the whole network. For example, after all online nodes in the block chain receive the transaction information acquisition request, respective local accounts are queried, and respective stored corresponding blocks are returned to the information verification device.
In step 520, a first block corresponding to the node number and the transaction time returned by one or more other nodes is received.
In step 530, the first block with the largest number of times of reception is used as the target block. For example, the information verification apparatus classifies the received first block, and takes the first block with the largest acquired data amount as the target block corresponding to the transaction ID. In some embodiments, the first block may be encrypted using the public key of the first node and signed using the information verification device private key after encryption is complete.
In step 540, the target block is returned to the first node, so that the first node acquires the first picture, the second picture or the third picture from the target block. In some embodiments, the first node may check the received information and then decrypt the information using its own private key to obtain the target block. The first node can obtain a picture corresponding to the transaction to be traced from the target block and return the picture to the user. Therefore, the user can acquire the picture information verified by each node from the blockchain as an evidence for transaction tracing, and the information credibility is improved.
In the above embodiment, the web page to be verified is converted into the picture as the transaction information and stored in the blockchain, and the transaction information is authenticated by using each node in the blockchain. Therefore, the data tampering preventing performance of the block chain is fully utilized, the authenticity of the transaction information is ensured, and the public confidence of the information is improved.

The first picture is obtained by converting the webpage to be verified for the first node. The receiver 61 is also used for receiving information verification success responses returned by one or more other nodes
In some embodiments, the information verification success response is returned by one or more other nodes when the hash value of the first picture is consistent with the hash value of the third picture, the third picture is obtained by converting the webpage corresponding to the URL by one or more other nodes, and the information verification success response includes the third picture.
The processor 62 is configured to perform the following steps: converting the webpage corresponding to the URL into a second picture; calculating a hash value of the second picture; determining that the transaction information passes the verification of the information verification device 6 under the condition that the hash value of the first picture is consistent with the hash value of the second picture; and under the condition that the number of successful responses of information verification returned by one or more other nodes exceeds a first threshold value, performing blocking processing on the transaction information to generate a first block, wherein the first block comprises a first picture or the second picture.
In some embodiments, the transaction information is obtained by the processor 62 decrypting the transaction information with the corresponding public key by encrypting the URL and the hash value of the first picture with the private key of the first node.
In some embodiments, processor 62 obtains the current maximum block height of the first node and one or more other nodes, and takes the maximum block height that is received the most times as the target height. The processor 62 performs blocking processing on the transaction information according to the target height to generate a first block.
In some embodiments, the processor sends an agglomeration success message to the first node and the one or more other nodes in the event that the number of block verification success replies returned by the first node and the one or more other nodes exceeds a second threshold, such that the first node and the one or more other nodes store the first block in response to the agglomeration success message. The block verification success response is that the first node and one or more other nodes return in the case that the pre-hash value of the first block is consistent with the hash value of a second block, the second block being a block whose block height is one step lower than the first block.
The sender 63 sends the transaction information to one or more other nodes in case the transaction information is de-verified by the information verification device 6, so that the one or more other nodes verify the transaction information. The transmitter 63 is also arranged to transmit the first block to the first node and one or more further nodes.
In some embodiments, the sender 63 forwards the transaction information acquisition request from the subject node to one or more other nodes. The transaction information acquisition request comprises a node number and transaction time. The receiver 61 receives the first block corresponding to the node number and the transaction time returned by one or more other nodes. The processor 62 uses the first block with the largest number of times of reception as a target block, and returns the target block to the first node through the transmitter, so that the first node acquires the first picture or the second picture or the third picture from the target block.
In some embodiments, the processor encrypts the target block using the public key of the first node, and digitally signs the encrypted target block to form a signature block. The sender returns the signature block to the first node.
In the above embodiment, the web page to be verified is converted into the picture as the transaction information and stored in the blockchain, and the transaction information is authenticated by using each node in the blockchain. Therefore, the data tampering preventing performance of the block chain is fully utilized, the authenticity of the transaction information is ensured, and the public confidence of the information is improved.
