S102: encrypting the first data, acquiring encrypted target data, judging whether data matched with the target data exist in data stored in a blockchain deployed by the electronic equipment, if not, storing the target data in the blockchain, and sending the target data to other nodes of the blockchain.
In order to ensure the security of the first data, the electronic device may encrypt the first data after acquiring the first data, and store the target data by referring to the encrypted first data as the target data, thereby improving the security of the data.
In addition, in order to avoid the waste of resources caused by repeated storage of the same data, in the embodiment of the present invention, the electronic device further determines whether there is data matching the target data in the data stored in the blockchain deployed thereon, where the data matching the target data is specifically data consistent with the target data. If the data matched with the target data does not exist in the data stored in the block chain deployed on the electronic equipment, the target data is stored in the block chain deployed on the electronic equipment, and the target data is sent to other nodes of the block chain, so that each node of the block chain stores the target data.
When the target data is sent to other nodes of the blockchain, a data transmission path can be established on the basis of the blockchain, and the target data is sent to the other nodes of the blockchain through the established data transmission path. Specifically, how to establish a data transmission path based on a blockchain and how to transmit data through the established data transmission path is the prior art and is not described herein.
In the embodiment of the invention, after the electronic equipment acquires the uploading instruction carrying the first data, the first data is encrypted, so that the safety of the first data is ensured, and when the data matched with the target data does not exist in the data stored in the blockchain deployed by the electronic equipment, the target data is stored in the blockchain, thereby avoiding the storage of repeated data in the blockchain and avoiding the resource waste. In addition, the electronic device stores the target data in the blockchain and also sends the target data to other nodes of the blockchain, that is, in the embodiment of the invention, the target data is stored in each node of the blockchain, so that when a single node is tampered with the attack data, the data stored in the other nodes are not tampered, and the situation that the single server is attacked and the data is tampered is avoided.
Example 2:
in order to improve the security of the data, in the embodiment of the present invention, encrypting the first data, and obtaining the encrypted target data includes:
performing hash operation on the first data;
and encrypting the first data after hash operation by adopting a preset encryption algorithm to obtain encrypted target data.
In order to improve the security of the data to be uploaded, in the embodiment of the present invention, after the electronic device acquires the first data, the electronic device may perform a hash operation on the first data. In order to further prevent the data from being leaked during uploading and still being easy to crack, after the electronic equipment performs hash operation on the first data, a preset encryption algorithm is adopted to encrypt the first data after the hash operation, and an encryption result is used as target data. In the embodiment of the invention, the identification heads in the data encrypted by different data by adopting a preset encryption algorithm are different.

Example 3:
in order to further improve the security of the data to be uploaded, in the above embodiments, after encrypting the first data and obtaining the encrypted target data, before determining whether there is data matching the target data in the data stored in the blockchain deployed by the electronic device, the method further includes:
dividing the target data into each target sub-data with the number of the included characters as the preset number according to the number of the characters in the target data and the preset number of the sub-data;
the sending the target data to other nodes of the blockchain includes:
and sending each target sub-data to other nodes of the blockchain.
Because the target data may be subjected to the situation that the data is leaked due to malicious packet capturing when the target data is sent to other nodes of the blockchain, in the embodiment of the invention, the electronic device can segment the target data into a plurality of target sub-data, the electronic device stores each target sub-data in the blockchain of the electronic device and sends each target sub-data to other nodes of the blockchain.
Specifically, after the electronic device obtains the encrypted target data, the electronic device may first obtain the number of characters included in the target data, and segment the target data into a plurality of target sub-data according to the number of characters included in the target data and the preset number of preset sub-data. The number of characters included in the target sub-data is a preset number, where the preset number may be any number greater than the number of characters included in the identification header of the first data, for example, the number of characters included in the identification header is 100, and the preset number may be 256.
The number of characters contained in the target data may not be a positive integer multiple of the preset number, that is, the target data may not be split equally, so in the embodiment of the present invention, when the data is split, the first character of the target data may start to split, the target data may be split into a plurality of target sub-data containing characters with the preset number, until the number of the last remaining characters is less than the preset number, and the last remaining characters are split into the last target sub-data.
In addition, after the electronic device acquires each target sub-data corresponding to the target data, the electronic device scrambles the target sub-data and sends the target sub-data to other nodes of the blockchain.
In the embodiment of the invention, when the target data is sent to other nodes of the blockchain, each target sub-data corresponding to the target data is sent, so that only one target sub-data is grabbed when a packet is grabbed, and the target sub-data is not complete, and the complete target data cannot be acquired according to one target sub-data, thereby avoiding the leakage of the target data and improving the safety of the data.
In addition, in the embodiment of the invention, when the target sub-data is sent to other nodes of the blockchain, other target sub-data except the target sub-data where the identification head is located can be compressed, so that the occupation ratio of the target sub-data is reduced, the target sub-data can be quickly sent to other nodes of the blockchain, and the transmission efficiency is improved.
And after receiving the data, other nodes in the blockchain automatically refresh, and record relevant information of the received data in an account book corresponding to the node. Specifically, how the blockchain automatically refreshes and how the related information of the received data is recorded in the corresponding account book is the prior art, and is not described herein again.
Example 4:
in order to avoid resource waste, based on the above embodiments, in the embodiment of the present invention, the determining whether the data matching the target data exists in the data stored in the blockchain deployed by the electronic device includes:
acquiring target sub-data carrying an identification head in the target sub-data, and acquiring the target identification head carried by the target sub-data; and acquiring each identification head carrying sub-data of the identification head stored in the blockchain deployed by the electronic equipment, and determining whether each acquired identification head has the identification head matched with the target identification head.
Because the same data may be repeatedly stored, which causes resource waste, in the embodiment of the present invention, the electronic device may determine whether there is data matching the target data in the data stored in the blockchain deployed thereon, thereby determining whether to store the target data.
Specifically, when the first data is encrypted, only the identification heads corresponding to the same data are consistent, so in the embodiment of the invention, if the blockchain deployed by the electronic device has the same data as the target data, the identification heads of the data stored in the blockchain have the same identification heads as the identification heads of the target data, and in the embodiment of the invention, not all the target sub-data corresponding to the target data do not contain the identification heads, but only one of the target sub-data contains the identification heads. Therefore, in the embodiment of the invention, when judging whether the data identical to the target data exists in the blockchain, the target identification head contained in the target sub-data containing the identification head can be acquired, each identification head in the data stored in the blockchain is acquired, and whether the identification head consistent with the target identification head exists in each identification head is determined.
In the embodiment of the invention, the number of the characters contained in the target sub-data is greater than that of the characters contained in the identification header of the first data, and the identification header is generally positioned at the head of the data, so that after the first data is divided to obtain a plurality of target sub-data, the first target sub-data is the target sub-data containing the identification header, and the target identification header carried by the target sub-data is obtained. And checking whether an identification head consistent with the target identification head is stored in a block chain deployed by the electronic equipment. Specifically, in order to improve the processing efficiency of the electronic device, the blockchain deployed by the electronic device may store each identifier header carrying sub-data of the identifier header, so after the electronic device obtains the target identifier header, the electronic device may obtain each identifier header carrying sub-data of the identifier header stored in the blockchain deployed by the electronic device, and determine whether there is an identifier header consistent with the target identifier header in each identifier header. If the identification head consistent with the target identification head exists, the fact that data matched with the target data exists in the data stored in the blockchain deployed by the electronic equipment is explained; if the identification head consistent with the target identification head does not exist, the fact that the data matched with the target data does not exist in the data stored in the blockchain deployed by the electronic equipment is indicated.
In addition, since the identifier header is generally recorded at the initial position of the target data, and the number of characters contained in the target sub-data is greater than the number of data contained in the identifier header, in the embodiment of the present invention, when the identifier header of the target data is acquired, the identifier header of the first target sub-data that is segmented may be acquired, specifically, for each target sub-data, the sorting identifier corresponding to the target sub-data may be determined according to the position of the target sub-data in the target data. And acquiring target sub-data with the sequence identification being a preset identification, and determining the identification head of the acquired target sub-data as a target identification head, wherein the preset identification is usually 1.

in order to avoid resource waste, in the embodiments of the present invention, if the target data exists in the data stored in the blockchain deployed by the electronic device, the method further includes:
deleting each target sub-data corresponding to the target data; or (b)
Acquiring sub-data corresponding to the identification head matched with the target identification head, deleting second data belonging to the sub-data stored in the blockchain, sending a notification of deleting the second data to other nodes of the blockchain, and storing each target sub-data corresponding to the target data.
In the embodiment of the invention, if the target data exists in the data stored in the blockchain deployed by the electronic equipment, in order to avoid resource waste, the electronic equipment can delete each target sub-data corresponding to the target data, so that each target sub-data corresponding to the target data is not stored in the blockchain, and the resource waste is avoided.
In addition, the electronic device can delete the data which is stored in the blockchain and is the same as the target data, and inform other nodes of the blockchain to delete the data which is the same as the target data. Specifically, the electronic device may acquire an identifier header stored in a blockchain deployed by the electronic device and matched with the target identifier header, acquire sub-data corresponding to the identifier header, delete second data to which the sub-data stored in the blockchain belongs, and send a notification of deleting the second data to other nodes of the blockchain, where after receiving the notification of deleting the second data, the other nodes of the blockchain delete the stored second data. In addition, the electronic device stores each target sub-data corresponding to the target data, and sends each target sub-data corresponding to the target data to other nodes of the blockchain, and the other nodes of the blockchain store each target sub-data corresponding to the target data after receiving the target sub-data.
In the embodiment of the invention, when the user selects the first data to be uploaded, the user can correspondingly select the category of the first data, and when the blockchain stores the target sub-data corresponding to the first data, the target sub-data corresponding to the first data is stored in the storage position corresponding to the category, that is, when the data is stored, the data is stored in a classified mode.
