Detailed Description
As shown in fig. 1, the block chain of the block chain big data security processing system of the present invention includes at least five nodes connected to each other, and is characterized in that: the node comprises
An input module for acquiring first data;
a control module for generating a hash value of the first data by the SHA256 algorithm;
the virus database is used for storing virus data, and the virus data are used for changing the arrangement mode of the first data, wherein the virus data correspond to a first pre-preset digit of the hash value of the first data;
the antivirus module is connected with the semi-private key library, and the semi-private key library stores antivirus data and is used for scanning virus data from the data packet and restoring the arrangement mode of the first data according to the file name of the virus data;
the sending module is connected with a virus database and used for packaging the virus data and the first data into a data packet and sending the data packet to other nodes of the block chain, wherein the arrangement mode of the first data is changed by the virus data;
the receiving module is used for being connected with the antivirus module, identifying the virus data in the data packet, restoring first data according to the file name of the virus data and sending a receipt;
the block chain big database is used for storing the restored first data and the first data arranged by the virus data;
a blockchain server which judges that the first data transmission is successful when more than half of the nodes receive the receipt.
The block chain server configured in the above way can add a half private key program which is constructed by controllable virus data and a virus killing module between the traditional public key and the traditional private key, thereby increasing the security and the credibility of each node for sending data.
The system comprises an input module, a control module, a virus database, a virus killing module, a sending module, a receiving module, a large block chain database and a block chain server, wherein the modules of each node are connected with each other or are connected on a main board together.
Since the conventional node is in a relatively closed block chain, the public key is required for transmitting a first data to decrypt the first data encrypted by the public key in each node, thereby obtaining the first data. After the transmission of the first data is completed, the two parties need to unlock the first data through the private key, and the private key is likely to be leaked due to the fact that the server is not trusted or the storage device is not trusted in the transmission process of the private key.
When the method is used, if the A wants to complete a transaction for the B by a block chain private key, the A can send the private key to the B through a non-network medium such as a U disk and the like so as to realize the safe data sending and avoid the occurrence of network theft. In the invention, the private key can be directly sent to the B by the A through the network, the antivirus data is transmitted to the B through the network, and the first data, the private key and the antivirus data which are sequentially modified by the virus are configured on the client of the node by the B, so that the restored initial first data is obtained, and the safer transmission of the data is realized.
Wherein each first data has an address corresponding thereto, and the private key is used to generate the address, thereby obtaining the first data by the address.
When the sending module packs the virus data and the first data into a data packet, the arrangement sequence of the first data is changed by the virus data in the same data packet.
The first data may be changed by the virus data in an arrangement manner, where the first data is a 256-bit 16-ary number, and the first data may be changed by the virus data in an arrangement manner as follows: the former part of the 256 bits is letters, and the latter part is hexadecimal digits of the numbers, so that the data content of the first data cannot be recognized by an external node.
The first preset number of bits may be the first 1, 2, 3, 4, 5, 6, 7, 8 bits of the hash value.
The virus data corresponds to a first pre-preset bit number of the hash value of the first data; it is understood that the hash value of the first data may be many, but the number of virus data is limited, and the corresponding case may be that one virus data corresponds to a plurality of hash values of the first data. Specifically, when the first pre-set number of bits is the first 5 bits, for example, the hash value of the first data is: 12345 sdjkfospifu 234oiu23oi4h23iuhr34h43 uihauosdfyh 9823rh72 hfjufkjfhf, the first five bits of the hash value of the first data are "12345", and such first data correspond to the same virus data in the virus database, thereby creating a one-to-many relationship so as not to store too much virus data. Since many first data may be the virus data whose first 5 bits of the hash value are "12345" and which affects the first data, the virus data only changes the arrangement order of the first data without deleting or adding the first data. The virus data may be arranged in a sequence of one letter or one number, or in a form of adding a "bottom row" to every 15 rows. And the antivirus module will recognize it and repair the first data according to its changed arrangement order. The invention limits the effect of the virus, namely the virus can only modify the arrangement sequence of the first data, thereby avoiding the system from being paralyzed due to miscalculation on other viruses, wherein the other viruses can increase or decrease the content of the first data or change the first data in other forms.
The virus killing module is connected with the virus database and used for scanning virus data from the data packet and restoring the arrangement mode of the first data according to the file name of the virus data; it can be understood that the antivirus module is also connected with the semi-private key library, that is, the antivirus module also has a database belonging to itself, the semi-private key library stores the transformation arrangement mode corresponding to the name of each virus data, and the original data of the first data before transformation can be reversely deduced according to the transformation mode. Or the antivirus module is provided with a recovery mode corresponding to the file name of each virus data and can recover the first data.
The hash value of the first data may be: when the first data is a long data, the hash value of the first data can be directly output, when the first data is a combination of a plurality of pieces of data, the hash value of the first data is the hash value of the first piece of data, and when the first data is a program, the hash value of the first data is the hash value of the name of the first data.
Preferably, referring to fig. 2, each node is provided with a geographic location sensing module, which is configured to detect location information of each node, when a change in a distance of more than half of the nodes in the block chain on the same day exceeds a preset threshold, the antivirus module recovers, within a preset time, first data, the sequence of which is changed by a virus, through antivirus data if a second pre-set bit number of a hash value of the distance difference between each node is completely the same as a second pre-set bit number of a hash value of current time data T, and if the first data is not completely the same as the second pre-set bit number of the hash value of the time data T, the block chain server isolates a data packet in which the first data is located and reconfigures all nodes to transmit the first data.
In the transmission process, as a lot of viruses are not uncontrollable, viruses and data time often generate more viruses due to data redundancy or the sequence of the first data is changed by the viruses invaded from the outside, then, in order to further increase the data security, a random time period can be adopted for restoring the first data, if the first data is not restored within a specified time, the data transmission is considered to have the situations of packet loss, data redundancy and virus invasion, a data packet of the data transmission needs to be isolated in time and retransmission needs to be attempted, and if the transmission is unsuccessful for a plurality of times, an alarm signal needs to be sent.
In the above process, at least more than half of the nodes are required to be constantly mobile, and the nodes can be a user's mobile phone, a notebook computer, a watch and an ipad.
Wherein the preset time may be (1s, 100s), preferably 3 seconds;
the random time can be comparable to the digging action of the bitcoin, and when the digging is successful, the first data is recovered, so that the foreign viruses capable of converting the first data are eliminated. For example, the total D is 4357389034559843 cm, the hash value is 123 jdffkgkls 2394jio, the time data T is 20190530200645899 ms, the hash value is 123sdfg54609054dfsjkgdfj, both of the first 3 bits of the two hash values are "123", it can be determined that the first data is restored from the beginning or from the beginning to the end of 3 seconds at that time, and if the first data is restored from the beginning or from the beginning to the end of the time period, it can be determined that packet loss, data redundancy, or virus intrusion has occurred in the data transmission.
Preferably, the preset threshold is preferably 3 kilometers.
There may be (1 km, + ∞), and optionally 3 km, that is, when the sum of the differences of the changes in the distances between 3 nodes on the day is greater than 3 km, among the at least five nodes, the decision may be continued downward.
Preferably, the second first preset number of bits is preferably the first 3 bits.
The second preset number of bits may be (1, 10), preferably 3 bits, that is, the distance hash value is the same as the first 3 bits of the time hash value, the first data whose sequence is changed by the virus is recovered within 3 seconds, and if the recovery of the first data is started or started to be completed outside the time period, it may be determined that packet loss, data redundancy, or virus intrusion has occurred in the data transmission.
The greater the number of bits, the slower, but more secure the data transfer. The smaller the number of bits, the faster, but less secure the data transfer. The particular number of bits may be determined by one skilled in the art based on the total amount of data transferred and the overall speed.
The processing method of the block chain big data safety processing system comprises the following steps:
step 1, acquiring first data;
step 2, generating a hash value of the first data through an SHA256 algorithm;
step 3, packaging the virus data and the first data into a data packet and sending the data packet to other nodes of the block chain, wherein the arrangement mode of the first data is changed by the virus data;
step 4, receiving and identifying the virus data in the data packet, restoring first data according to the file name of the virus data and sending a receipt;
and 5, judging that the first data is successfully transmitted when more than half of the nodes receive the receipt.
The above-mentioned embodiments are merely illustrative of the preferred embodiments of the present invention, and do not limit the scope of the present invention, and various modifications and improvements of the technical solution of the present invention by those skilled in the art should fall within the protection scope defined by the claims of the present invention without departing from the spirit of the present invention.
