Detailed Description
As shown in fig. 1 and 2, the blockchain of the blockchain big data security processing system according to the present invention includes 7 nodes 100, where each node 100 stores each word of the second data and the position of the word in the second data in the blockchain backup database of each node 100 through a data splitting module, compares the third data synthesized by the blockchain backup database of each node 100 with the second data, and deletes the second data in the blockchain big database of each node 100 if the third data is different from the second data.
According to the invention, the data is split and respectively stored to each node 100, so that the whole second data cannot be completely operated, the influence of virus data or redundant data generated in the transmission process on the safety of the whole block chain large database is avoided, and the unsafe data which are stored and cannot be the same as the original data are deleted, so that the data safety of the block chain large database can be ensured.
That is, after the second data such as the virus program is split, the second data cannot be completely run, or after the data transmission occurs, the generated redundant data is split, more redundant data may be generated or corrected, and after the comparison, if the data is different, the second data is regarded as unsafe data, and is deleted in the large block chain database.
Preferably, referring to fig. 2, each of said nodes 100 comprises
An acquisition module for inputting first data;
the block chain safety database is used for storing illegal data;
the primary matching module is used for comparing the first data with the illegal data, and converting the first data into second data for output if the first data is matched with the illegal data;
a blockchain backup database for storing each word of the split second data corresponding to the node 100 where the word is located and the position of the word in the second data;
a data splitting module, configured to split the second data into a plurality of words and positions of the words in the second data, and allocate the words with initial letters or numbers to the blockchain backup databases of the corresponding nodes 100;
a sending module, configured to compare the second data with the illegal data in the block chain security database, and if the second data is different from the illegal data in the block chain security database, send the second data to other nodes 100 in the block chain, and if the second data is the same as the illegal data in the block chain security database, not send the second data;
a receiving module, configured to receive second data sent by other nodes 100 in the block chain;
a blockchain big database for storing second data;
and the control module is configured to synthesize third data according to each word of the second data in the blockchain backup database in each node 100 and the position of the word in the second data, compare the third data with the second data, and if the third data is different from the second data, store the second data in the blockchain security database and delete the second data in the blockchain large database.
According to the invention, each second data can be split into a plurality of words, and then the backed up regenerated third data is compared with the original second data before splitting, if the second data is consistent, the data is stored in the big block chain database safely, and if the second data is inconsistent, the node 100 sending the second data sends out wrong second data, possibly the node 100 sends out virus or redundant data, on one hand, the node 100 can indicate that the client of the node 100 is not safe or the node 100 sends out dangerous virus data for breaking the block chain, so as to tamper the data in the big block chain database. By the method, the data sent by each node 100 can be compared, so that targeted interception is deleted, the data safety in a large database of a block chain is ensured, and the data safety of each node 100 is ensured.
Preferably, the control module compares the third data with the second data, if the third data is the same as the second data, the score of the node 100 that sends the second data is increased, and if the third data is not the same as the second data, the score of the node 100 that sends the second data is decreased, wherein if the score of the node 100 is lower than a preset threshold, the sending module of the node 100 cannot send data.
According to the invention, each node 100 which is sent and is considered as illegal data is deducted by the scoring means, certain tolerance is carried out on the node 100, and the permission of the node 100 for sending data is stopped if the illegal data is sent for a plurality of times, so that a safe block chain large database is constructed.
Preferably, the control module obtains the sending quantity a of the node 100 sending the second data in the first time to all the nodes in the block chainObtaining a percentage c of a total amount b sent by the node 100 in a first time, obtaining a quantity d of second data, different from third data, sent by the node 100 sending the second data in the first time, and increasing or decreasing a score e of the node 100 sending the second data each time when the third data is compared with the second data to judge whether the third data is the same as or different from the second data, according to the following formula:
the preset threshold of the control module is 60 minutes, each node 100 returns to an initial score of 65 minutes after the completion of the first time each time, when the comparison and judgment of the third data and the second data are the same each time, the real-time score of each node 100 is increased by e, when the comparison and judgment of the third data and the second data are different each time, the real-time score of each node 100 is decreased by e, and when the real-time score of the node 100 is lower than the preset threshold, the sending module of the node 100 cannot send data.
According to the invention, a more targeted unit score e can be obtained based on the sending amount a, the sending total amount b, the percentage c and the number d, and e is increased every time the unit score e is the same, and e is not reduced every time the unit score e is different, so that the real-time score of each node 100 can relatively fluctuate in the first time every time, and when the real-time score is lower than a preset threshold value, the node 100 is judged to carry out a large amount of illegal operations, and the data sending of the node is limited.
It should be noted that, at the end of each first time or at the beginning of each first time, the score of the node 100 is 65 points, and when the score of the node 100 is lower than 60 points, the node 100 is considered to transmit the illegal data in a large amount for a short time, and stops transmitting the data again. Wherein the above formula is represented by
As a constant for comparison, the constant is increased by increasing the transmission amount a of the node 100, thereby affecting the node 100 to be increased or decreased each timeAnd (6) grading in real time. In the case that the total transmission amount b is relatively stable with the increase of the transmission amount a, the increase of the transmission amount a and the increase of the percentage c will increase the fluctuation of the real-time score of the node 100 in each increase or decrease to influence the real-time score thereof. When the number d is small, the system may understand that the node 100 sends a transmission error due to data redundancy or transmission packet loss, and has a part of tolerance to the transmission error, so as to ensure smooth operation of the node 100, and when the number d is large, the system tends to influence the size of the whole e, i.e. the fluctuation amount of the real-time score, so that when the node 100 sends a large amount of illegal data in a short time, the illegal number is quickly identified, the real-time score is changed, and the node cannot send data, so as to ensure the security of the large database of the block chain.
The length of the first time can be obtained by a person skilled in the art through a plurality of tests according to the computing power and the processing power of the control module, and the smaller the first time is, the safer the first time is, but the more computing power is occupied. For example, when the first time is an hour, the first time is divided into 24 times per day, the transmission amount a, the transmission total amount b, the percentage c, and the amount d are counted in each first time, and the score of each node 100 is classified as an initial state in each first time.
Preferably, there are at least 37 nodes 100, and the words beginning with letters, numbers and punctuation marks by the data splitting module are respectively stored in the blockchain backup database of the corresponding node 100;
wherein the blockchain backup database of 26 nodes 100 is used for storing the split words of the second data beginning with 26 letters and the positions of the words in the second data,
wherein, the blockchain backup database of 10 nodes 100 is used for storing the split words of the 10 digital beginning second data of 0-9 and the positions of the words in the second data,
the blockchain backup database of 1 node 100 is used to store the split words of the second data beginning with the punctuation mark and the positions of the words in the second data.
According to the invention, each word can be split in the form of letters, numbers and punctuation marks and then synthesized, so that the data stored in each block chain backup database are different, and the words can be synthesized into second data according to the splitting mode and converted into third data, so that the second data is compared with the original second data to ensure that the second data is not changed after being stored in the block chain big database, so that the safety of the data is ensured, the Trojan horse data is prevented from changing in the block chain big database, and the data in the block chain big database is stolen and modified.
The Chinese characters are words of Chinese language and can be distributed to the block chain backup database of the node 100 of the corresponding letter according to the first letter of the Chinese pinyin.
The splits and combinations are shown in the following table:
| second data | "I love you 1314 a" |
| 37 th node | (", first position) |
| 23 rd node | (I, second position) |
| 1 st node | (love, third position) |
