The embodiments of the data uplink apparatus of the present invention are substantially the same as the embodiments of the data uplink method described below, and are not repeated herein.
The invention provides a data uplink method.
Referring to fig. 2, fig. 2 is a flowchart illustrating a data uplink method according to a first embodiment of the present invention.
Step S101, regularly acquiring the certificate storage file character strings of a preset number and the certificate storage file numbers of the certificate storage file character strings from a certificate storage file database;
in this embodiment, the data uplink method is applied to data uplink equipment, the data uplink equipment is connected with a certificate storage database, and a certificate storage file character string and a certificate storage file number of the certificate storage file character string are stored in the certificate storage database, wherein the certificate storage file is subjected to hash processing to obtain the certificate storage file character string, and the certificate storage file includes, but is not limited to, a contract file, a house property certificate file, and a credit report file. The data uplink equipment acquires the certificate storage file character strings and the certificate storage file numbers of the certificate storage file character strings in preset quantity from the certificate storage file database at regular time, namely acquires the certificate storage file character strings and the certificate storage file numbers of the certificate storage file character strings in preset quantity from the certificate storage file database at preset time intervals. It should be noted that the preset time and the preset number may be set by those skilled in the art based on actual situations, and this embodiment is not limited in this respect.
Further, when the certificate storing request is monitored, the data uplink equipment acquires the certificate storing file from the certificate storing request, performs hash processing on the certificate storing file to obtain a certificate storing file character string, distributes a certificate storing file number to the certificate storing file character string, and stores the certificate storing file character string and the certificate storing file number in a certificate storing file database in an associated manner. After a client initiates a certificate storage request to the data uplink equipment through the terminal equipment, the data uplink equipment can reduce the size of the certificate storage file after performing hash processing on the certificate storage file in the certificate storage request, is convenient to store, and meanwhile allocates a corresponding certificate storage file number to the certificate storage file character string, so that subsequent acquisition is facilitated.
Step S102, merging a preset number of the certificate-storing file character strings to obtain merged character strings, carrying out Hash processing on the merged character strings to obtain target character strings, and signing the target character strings to obtain signature character strings;
in this embodiment, after obtaining the certificate-storing file character strings of the preset number and the certificate-storing file numbers of the certificate-storing file character strings, the data chaining device merges the certificate-storing file character strings of the preset number to obtain merged character strings, that is, merges the certificate-storing file character strings of the preset number into one character string through the preset connectors to obtain the merged character strings; and then carrying out Hash processing on the combined character string to obtain a target character string, and signing the target character string to obtain a signature character string, namely signing the target character string through a preset signature algorithm and a preset public and private key to obtain the signature character string. It should be noted that the preset connector, the preset signature algorithm, and the preset public and private keys may be set by those skilled in the art based on actual situations, and this embodiment is not limited in this respect. Optionally, the preset connector is a comma.
The merging mode of the certificate-storing file character strings comprises sequential merging, reverse-order merging and random merging, the sequential merging is to sort the certificate-storing file character strings according to the certificate-storing file numbers of the certificate-storing file character strings to obtain a certificate-storing file character string queue, and then the certificate-storing file character strings in the certificate-storing file character string queue are sequentially connected with the certificate-storing file character strings through preset connectors according to the sequence of the certificate-storing file character strings in the certificate-storing file character string queue to obtain a merged character string; the reverse order combination is that the certificate storage file character strings are sequenced according to the certificate storage file numbers of the certificate storage file character strings to obtain a certificate storage file character string queue, then the sequence of the certificate storage file character strings in the certificate storage file character string queue is reversed, and the certificate storage file character strings in the certificate storage file character string queue are sequentially connected through a preset connector to obtain a combined character string; the random combination is that firstly two certificate storage file character strings are randomly selected from a preset number of certificate storage file character strings, the two certificate storage file character strings are connected through a preset connector to obtain a combined character string, then one certificate storage file character string is randomly selected from the rest certificate storage file character strings each time, and the selected certificate storage file character string is randomly inserted into the last combined character string through the preset connector until the certificate storage file character strings are combined.
For example, assuming that the document file strings in the document file string queue are hashS1, hashS2, hashS3, hashS4, hashS5, hashS6, hashS7, and hashS8, and the arrangement order is hashS3, hashS2, hashS1, hashS5, hashS4, hashS7, hashS6, and hashS8, and the preset connector is comma ",", through which the 8 document strings are combined in the "sequential combination manner", and the resulting combined string is hashD "(" hashS3, hashS2, hashS1, hashS5, and the combined hashS5, and 5, and 5, and the combined in a combined hash of a hash, a hash, a hash, a, another resulting merged string is hashD ═ hashS4, hashS6, hashS5, hashS1, hashS2, hashS8, hashS3, hashS 7.
Step S103, taking the certificate storing file number, the merging character string, the target character string and the signature character string as data to be uplinked and uploading the data to a block chain.
In this embodiment, after the merged string, the target string, and the signature string are obtained, the data chaining device uploads the certificate storing file number, the merged string, the target string, and the signature string as data to be chained to the block chain. When a corresponding block chain link point in a block chain receives to-be-uplink data uploaded by data uplink equipment, the block chain link point writes the to-be-uplink data into the block chain, receives a contract address returned by the block chain, broadcasts the contract address to other block chain nodes in the block chain, obtains a corresponding target character string from the block chain by the other block chain link points according to the contract address, signs the target character string to obtain a signature character string corresponding to each other block chain link point, and writes the signature character string corresponding to each other block chain node into the block chain.
In this embodiment, the present invention periodically obtains a preset number of certificate-storing file character strings and certificate-storing file numbers thereof from a certificate-storing file database, merges the preset number of certificate-storing file character strings into one character string to obtain a merged character string, performs hash processing on the merged character string to obtain a target character string, performs signature on the target character string to obtain a signature character string, and finally uploads the certificate-storing file number, the merged character string, the target character string, and the signature character string as data to be uplink-linked to a block chain.
Further, based on the first embodiment, a second embodiment of the data uplink method of the present invention is provided, which is different from the foregoing embodiments in that after the data to be uplink is uploaded to the block chain, each block chain node of the block chain signs the data to be uplink, and returns a corresponding contract address to the data uplink device, and the data uplink device receives the contract address returned by the block chain and stores the certification file number, the merge character string, the target character string, and the contract address as a uplink record in the certification file database; then regularly scanning the uplink records in the certificate storage file database, obtaining target uplink records which do not carry signature completion marks, obtaining contract addresses from the target uplink records, then obtaining corresponding target character strings and signature character strings of each block chain node from the block chain according to the contract addresses, judging whether unsigned block chain link points exist in each block chain node or not according to the target character strings and the signature character strings of each block chain node, if unsigned block chain link points do not exist in each block chain node, carrying out signature completion marks on the target uplink records, if unsigned block chain link points exist in each block chain node, sending name requests to the unsigned block chain link points, obtaining the corresponding target character strings from the block chain by the unsigned block chain link points according to the contract addresses in the signature requests, and signing the target character string to obtain a signature character string corresponding to each block chain link point, and writing the signature character string corresponding to the block chain link point into the block chain to complete signature.
Specifically, the signature character string of each block chain node is verified according to the target character string to obtain a verification result of the signature character string of each block chain node, and then whether an unsigned block chain link point exists in each block chain node is judged according to the verification result of the signature character string of each block chain node. The specific verification method of the signature character string of each block chain node is to calculate a public key corresponding to each block chain link point according to the target character string, a preset signature algorithm and the signature character string, acquire a preset public key corresponding to each block chain link point, judge whether the public key corresponding to each block chain link point is the same as the preset public key corresponding to each block chain link point, if the public key of one block chain node is the same as the preset public key corresponding to the block chain link point, the verification result of the signature character string of the block chain link point is verification pass, and if the public key of one block chain node is different from the preset public key corresponding to the block chain link point, the verification result of the signature character string of the block chain link point is verification fail. The verification result of the signature character string is that the block chain link point which fails to be verified is an unsigned block chain link point, and the verification result of the signature character string is that the block chain link point which passes to be verified is a signed block chain link point.
In specific implementation, whether a signature character string of each block chain node is stored in a block chain is judged according to the contract address, if the signature character string of each block chain node is stored in the block chain, a corresponding target character string and the signature character string of each block chain node are obtained from the block chain according to the contract address, whether an unsigned block chain node exists in each block chain node is judged according to the target character string and the signature character string of each block chain node, if the unsigned block chain node does not exist in each block chain node, a signature completion mark is carried out on a target uplink record, and if the unsigned block chain node exists in each block chain node, a signature point name request is sent to the unsigned block chain node; and if the signature character strings stored in the block chain do not comprise the signature character strings of all the block chain nodes, determining that unsigned block chain nodes exist in each block chain node, and sending a signature request to the unsigned block chain nodes.
In this embodiment, the present invention scans an uplink record in a certificate storage file database at regular time, and obtains a target character string and a signature character string of each block chain node from a block chain through a contract address in the uplink record, and then determines whether an unsigned block link point exists in each block chain node through the target character string and the signature character string of each block chain node, if so, sends a signature request to the corresponding block link point, and if not, marks the signature completion on the uplink record, so as to verify whether each block link point is signed completely.
Further, based on the first or second embodiment, a third embodiment of the data uplink method of the present invention is provided, which is different from the foregoing embodiment in that when a forensics request is detected, the data uplink apparatus acquires a forensics file character string from the forensics request, acquires a corresponding contract address from a forensics file database according to the forensics file character string, then sends the forensics file character string and the contract address to a corresponding block chain node in a block chain, executes a signature verification operation by the corresponding block chain node in the block chain according to the contract address and the forensics file character string, obtains a signature verification result, and executes the signature verification operation when the signature verification result is a pass.
Specifically, corresponding block chain link points in the block chain acquire corresponding merged character strings, target character strings and signature character strings from the block chain according to the contract address, judge whether the merged character strings contain the certificate-storing file character strings, and return corresponding reminding information to the data uplink equipment if the merged character strings do not contain the certificate-storing file character strings; if the merged character string contains the certificate storing file character string, judging whether the signature character string is correct or not according to the target character string, namely calculating a public key of the block chain node according to the target character string, a preset signature algorithm and the signature character string, acquiring a preset public key corresponding to the block chain node, judging whether the public key is the same as the preset public key or not, judging that the signature character string is correct if the public key is the same as the preset public key, and judging that the signature character string is incorrect if the public key is different from the preset public key; if the signature character string is correct, the certification operation is executed, and if the signature character string is incorrect, the corresponding reminding information is returned to the data uplink equipment.
