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.

Fig. 1 illustrates a flow diagram of a data transmission method according to some embodiments of the present disclosure.

As shown in fig. 1, the data transmission method includes steps S110 to S140. In some embodiments, the data transmission method is performed by a terminal. For example, a data sender or a terminal of a data provider may perform a data transmission operation through Dapp (Decentralized Application).

In step S110, data is acquired. For example, the data is a packet. In some embodiments, the data sender uploads the data packet to the terminal.

In step S120, a data code is generated from the data. The data code is generated, for example, as follows.

The step of generating the data encoding S120 will be described in detail below in conjunction with fig. 2.

Fig. 2 illustrates a schematic diagram of generating a data encoding, according to some embodiments of the present disclosure.

First, data is decomposed to obtain a plurality of data blocks. As shown in fig. 2, the data is, for example, 500 packets (e.g., 100M in size). The 500 packets are broken up into 100 data blocks, each of 1M size. In some embodiments, each of the plurality of data blocks has a sequence number. The sequence number is used to identify the order of the individual data blocks. As shown in fig. 2, for example, 100 data blocks are sorted to obtain

sequence numbers

1, 2, 3, and 4 … of the respective data blocks.

Sequence numbers

1, 2, 3, 4 … identify the order of the individual data blocks. It should be noted that the size of each data block may be set according to actual circumstances.

Each data block is then assigned a label. In some embodiments, each data block is assigned a base tag comprising adenine a, guanine G, cytosine C, or thymine T. Adenine A, guanine G, cytosine C, and thymine T are four different bases in genetics. As shown in FIG. 2, for example, one base tag is randomly assigned to each of 100 data blocks to obtain a base code of-A-T-C-G-A-T-C-G- ….

And finally, generating a data code according to the labels of the plurality of data blocks. In some embodiments, the data encoding is generated based on base labeling using base pairing rules. The base pairing rule is that A corresponds to T, C and G corresponds to G. As shown in FIG. 2, for mut mutexample, the data encoding-T-A-G-C-T-A-G-C- … corresponding to the base code is obtained by using the base pairing rule.

In step S130, the data is transmitted to the data container. For example, the order of a plurality of data blocks is first scrambled to obtain processed data, and then the processed data is sent to a data container. As shown in fig. 2, for example, the order of the scrambled data blocks is 4, 3, 2, 100, 56 ….

In some embodiments, the data container is a public cloud or data intermediate storage device, providing data storage functionality.

In some embodiments, the plurality of data blocks and the data encoding have the same time stamp. The time stamp is, for example, a data generation time. For example, the data container includes a plurality of data partitions. Each data partition corresponds to a time period.

The data may be sent to the data container, for example, as follows. And sending each data block of the data to the corresponding data partition according to the corresponding relation between the time stamp of each data block corresponding to the data and the time period of each data partition.

In some embodiments, the data container breaks up the data blocks corresponding to the data packets, and uniformly mixes the data blocks corresponding to all the data packets of the data container, thereby further improving the security. The data container has a large number of data blocks, which increases the difficulty of maliciously acquiring data through the permutation and combination scheme.

In step S140, the data encoding is sent to the block chain. For example, a data sender uploads data to a block chain through a terminal.

In some embodiments, the data transmission method further comprises the following steps.

First, a broadcast message is generated according to data encoding. In some embodiments, the data sender writes the data codes into the blocks through the terminal, and generates the triple < data codes, the account of the data sender, and the account of the data receiver >.

The broadcast message is then private key signed. In some embodiments, the data sender also pays for the blockchain system usage fee fuel GAS through the terminal.

And finally, broadcasting the broadcast message signed by the private key to the block chain. In some embodiments, the broadcast message includes a data encoding and message digest plaintext. The message digest plaintext is, for example, a description of the data source, the data amount, and the data type. In some embodiments, the summary plaintext of a broadcast message is a description of the name of the sender of data, 500 data, and the full amount of data.

Fig. 3 illustrates a flow diagram of a method of data transmission according to further embodiments of the present disclosure.

As shown in fig. 3, the data transmission method includes steps S310 to S320. For example, the data receiving side performs the data transmission method through the terminal.

In step S310, data codes are acquired from the blockchain. In some embodiments, obtaining data encoding from a blockchain is accomplished as follows.

First, a broadcast message signed by a private key of a block chain is received and browsed. For example, browse the summary plaintext of the broadcast message, generate the browsing record quadruplet < data code, browsing record, account of the data sender, account of the data receiver >.

Then, the data code is obtained from the broadcast message signed by the private key. For example, the data receiver signs the browsing record through a terminal by a private key, pays the TOKEN and the blockchain system usage charge GAS to the data sender, and broadcasts to the blockchain whole network.

In some embodiments, after receiving the browsing record of the data receiving party, the miners browse and extract the transaction hash values, pair the transaction hash values, obtain the merkel roots by adopting the prior art, assemble the blocks, and link the blocks to the main block chain. So far, the data receiver can browse and acquire the data codes in the broadcast message. It should be understood that the present disclosure is built based on public chains, and therefore POW or POS can be adopted as the prior art of consensus algorithm, etc., which is not described herein in detail.

In step S320, corresponding data is acquired from the data container according to the data encoding. In some embodiments, the corresponding data is obtained from the data container as follows.

First, a plurality of data blocks corresponding to data are acquired from a data container according to data encoding. For example, a plurality of data chunks of corresponding data are retrieved from the data container according to the data encoding and the timestamp corresponding to the data encoding. In some embodiments, the data encoding includes a base tag corresponding to each data block. And acquiring a plurality of data blocks of corresponding data from the data container by using a base pairing principle according to the base label corresponding to each data block and the time stamp. For example, T, G, A, C, G data chunks comprising base labels of corresponding data are obtained from the data container according to the data code A-C-T-G-C and timestamp 1.

In some embodiments, the data container includes a plurality of data partitions, each corresponding to a respective time period. And acquiring a plurality of data blocks from the corresponding data partitions according to the corresponding relation between the time stamps corresponding to the data and the time periods corresponding to the data partitions of the data container. For example, with a timestamp of 1, multiple data blocks should be retrieved from a data partition with a time period of 0-3.

And then, restoring to obtain corresponding data according to the plurality of data blocks. In some embodiments, each data block includes a sequence number. And sequencing each data block according to the sequence number of each data block, and restoring to obtain corresponding data. For example, T, G, A, C, G data blocks having base labels include

sequence numbers

1, 4, 3, and 2. And sequencing the data blocks according to the sequence numbers to obtain corresponding data 1(T) -2(G) -3(C) -4 (G). It should be noted that due to the randomness in generating the data blocks, the probability of the existence of data blocks with consistent time stamps and consistent base labels is low, and this disclosure will not be discussed in detail at this time.

The data codes generated by the data transmission method have uniqueness and are not influenced by a data sender and a data receiver. The two data transmission parties do not need to verify whether the hash values corresponding to the data packets are consistent, the link that whether the hash values of the data packets acquired by the data receiving party and the hash values of the data packets directly acquired from the data transmitting party are consistent is reduced, operation is reduced, and therefore the efficiency of the block chain is improved.
