Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be illustrative of the present invention and should not be construed as limiting the present invention, and all other embodiments that can be obtained by one skilled in the art based on the embodiments of the present invention without inventive efforts shall fall within the scope of protection of the present invention.
To solve the above technical problem, the present invention provides a data uplink method for a block chain node, and referring to fig. 1, the data uplink method for the block chain node includes:
step S10, receiving target data sent by the block chain node;
it is understood that the block link point refers to an operation terminal, such as a mobile phone, an iPad, a computer, and the like, which has a certain storage space and can be connected to a network, and the operation terminal runs a corresponding program of the block chain in the storage space of the connected network.
Step S20, judging whether the target data contains preset safety words or not so as to carry out safety verification on the target data;
after the block chain system receives the target data sent by the block chain nodes, the target data and the safety words in the safety word list are compared one by one to judge whether the target data contain the safety words or not, and therefore data safety of the target data is verified.
Step S30, if the security word is included, the target data is linked up;
after the target data is compared with the preset safety words one by one, if one or more safety words are found in the target data, the target data can be judged to be safety data, and the target data is uploaded to the block chain.
Referring to fig. 4, in a preferred embodiment of the present invention, the step S30 includes:
step S31, screening safety words from the target data according to a preset safety word list, and generating target data which do not contain the safety words;
in this embodiment, the target data is compared with a preset security word list to screen out security words from the target data, so as to obtain target data that does not include security words.
Step S32 is to encode target data that does not include the security word, and to broadcast the encoded target data to each tile link point.
After the safety words are screened out from the target data, the target data are coded to form coded characters which can be processed and analyzed by a computer, and then the coded target data are sent to each block chain node in a broadcasting mode.
Step S40, if the security word is not included, the target data is prohibited from being uplink and a prompt message of uplink failure is sent after a first preset time interval.
After the target data is compared with preset safety words one by one, if the target data does not contain the safety words, the target data is marked as unsafe data, the target data is forbidden to be subjected to chain loading, and prompt information of chain loading failure is sent after a first preset time interval.
It should be noted that target data that does not include the security word can be sent out and received by each blockchain node, but since the target data does not include the security word, it is prohibited from uplink transmission. Further, the blockchain system sends a warning message of uplink failure to the user after a certain time interval, for example, after 4 hours interval, the blockchain system sends a warning message of uplink failure to the blockchain node of the user to remind the user to upload the target data correctly, and meanwhile, information uplink of the user in an involuntary state is avoided.
In the embodiment of the present invention, when each blockchain node accesses the blockchain system, a list containing a preset number of security words is stored, and all users are required to add one or more security words when inputting data through the blockchain nodes, and target data to which no security word is added will be marked as unsafe data and uplink is prohibited.
The above-mentioned safety words refer to a segment of digital codes preset and confirmed by a blockchain system, and may be words with semantic meanings, such as english words, chinese idioms, and the like, or specific digital combinations without semantic meanings, such as plantar pressure data values, geographic coordinate values, and the like.
For example, the target information entered by the user, libo, is: "5/13/14: 00 in 2019, 2% interest in famous painting 023, transferred from user 258963469 to user 896325974". If libo only inputs the above information and sends it to the blockchain system, the blockchain system will mark the target information as "unsafe" and prohibit the target information from being uplinked after receiving the above information.
After a first predetermined time, for example, 4 hours, the blockchain system sends a notification message of uplink failure to the blockchain node of rood. After reading the prompt message, the rooster plum can add one or more preset safety words on the basis of the original message, such as: the information is modified to be ' 14:00 in 5.13.5.2019. the interest of 2% famous painting of 023 ' and the user is transferred from 258963469 to 896325974 '. The libo sends the relevant information to the blockchain system again, passes the security verification of the blockchain system, and then is coded and linked up.
In a preferred embodiment, referring to fig. 2, the method for data uplink of a blockchain node further includes:
step S50, sending a security word list updating request to at least one of the block link nodes at intervals of second preset time according to the sequence of the registration time of the block link nodes;
it is understood that the earlier the user registers the blockchain node, the more familiar it is with the security word rules, and therefore the user can maintain the stability of the blockchain system to the maximum extent by uploading the security word list from the blockchain node.
In this embodiment, the block chain system sends, to at least one block chain node, a security word list update request every second preset time according to the sequence of the registration times of the block chain nodes, where the security word list update request may be sent only to a block chain link with the earliest registration time, or may be sent to multiple block chain links in sequence according to the sequence of the registration times.
Step S60, receiving the safety word list uploaded by at least one block chain node in a third preset time, and sorting and confirming the updated safety word list;
it can be understood that, in the block chain link point, there is a case that the security word list cannot be uploaded in time due to human factors, and in order to ensure stable operation of the block chain system, the block chain system cannot stop operating to wait for uploading of the security word list, and therefore, a "deadline" needs to be set so that the block chain system can start a next process.
Further, if no user uploads a list of security words within a specified "deadline," the blockchain system will default to the last list of security words to continue to be active.
In this embodiment, after receiving and agreeing to the security word update request sent by the blockchain system, the blockchain link point uploads the updated security word list to the blockchain system within a third preset time, and the blockchain system sorts and confirms the updated security word list.
Referring to fig. 3, if the list of security words received by the blockchain system is multiple, the step S60 includes:
step S61, sequentially taking the safe word list of the block chain node with the earlier registration time as a reference to screen the safe words in the safe word list of the block chain node with the later registration time;
assume that the security word list uploaded at a block chain node a is 123456abcd, the security word list uploaded at a block chain node B is 123789defg, and the security word list uploaded at a block chain node C is 789abdehij, where the registration time of the block chain node a is prior to the block chain node B, and the registration time of the block chain node B is prior to the block chain node C.
Firstly, taking a safety word list 123456abcd uploaded by a block chain node A as a reference, respectively carrying out first weight screening processing on a safety word list of a block chain link point B and a safety word list of a block chain node C, wherein after the first weight screening, the safety word list of the block chain node B is 789defg, and the safety word list of the block chain link point C is 789 ehij; and then, taking the safe word list of the block chain node B subjected to the first weight screening as a reference, carrying out secondary weight screening processing on the safe word list of the block chain node C subjected to the first weight screening, wherein the safe word list of the block chain node C subjected to the secondary weight screening is hij.
Step S62, distributing corresponding weight factors to each safety word list after the filtering and re-screening processing according to the registration time of the block chain nodes of the uploaded safety word list;
in step S61, according to the length of the registration time of the block chain node a, the block link point B, and the block link point C, a corresponding weighting factor is assigned to each filtered list of security words, for example, the weighting factors of the block chain node a, the block link point B, and the block link point C are 0.5, 0.3, and 0.2, respectively.
And step S63, selecting a corresponding number of security words from each security word list after the screening and the rearrangement processing according to the preset total amount of the security words and each weight factor.
Assuming that the total amount of the preset security words is 10, according to the security word list after the filtering in step S61 and the weighting factor determined in step S62, 5, 3, and 2 security words are randomly selected from the block link point a, the block link point B, and the block link point C after the filtering, for example, 12345 is selected from the block link node a, 789 is selected from the block link point B, and hj is selected from the block link point C, so that the updated security word list 12345789hj is obtained.
Step S70, the updated list of security words is broadcast to each tile link point.
In the embodiment of the invention, after the safety word list is sorted and confirmed, an updated safety word list is obtained, and then the updated safety word list is sent to each block chain link point for storage in a broadcasting mode.
