Description

Technical Field

[0001] The present invention relates to the technical field of security protection, and particularly to a secure blockchain big data cloud platform through an intelligent mobile terminal. Background Art

[0002] When a user needs to log in to a web version of an application system on a web page, the user can first enter the website address of the web version of the application system in a browser. The browser displays a login box on the web page. If the user logs in to the account in the browser for the first time, the user needs to enter the account password information in the login box on the web page to complete the login; if the user is not logging in to the account in the browser for the first time, the browser can obtain the account password information recorded during the user's last login and automatically fill it into the login box on the web page to complete the login. Patent Application No. 2022103143891, titled "Account Login Method and System Based on Blockchain", discloses the following: The terminal stores the account password information and the website address information corresponding to each other in the blockchain. The website address information is the address of the target web page that requires the account password information to log in; when the user accesses the target web page in the browser, the browser plugin negotiates a key with the terminal through the server; the terminal obtains the account password information corresponding to the target web page from the blockchain, encrypts the account password information with the key to obtain the first ciphertext, and sends the first ciphertext to the browser plugin through the server; the browser plugin decrypts the first ciphertext with the key to obtain the account password information and logs in to the target web page according to the account password information. This application not only avoids the user from memorizing the account password information but also ensures that the account password information is not leaked, thus ensuring the storage security of the account password information. It can also ensure the transmission security of the account password information through the key. And the present invention provides another secure login method. Summary of the Invention

[0185] In a preferred embodiment of the present invention, the method for performing secure communication processing on the input login account in step S14 to obtain a secure communication account is:

[0188] Secure communication processing() represents the secure communication processing method, preferably using the MD5 algorithm; its value is a 32-bit hexadecimal character; all letters are uppercase letters.

[0189] Login account represents the login account;

[0190] The method for performing secure communication processing on the input login password to obtain a secure communication password is:

[0205] In a preferred embodiment of the present invention, in step S17, the method for obtaining the platform account by performing platform verification processing on the obtained communication extraction account is as follows:

[0206] Platform secure account = Platform validationprocessing(Receive secureaccount)

[0207] Among them, Platform secure account represents the platform account;

[0208] Platform validation processing() represents platform verification processing; preferably, the MD5 algorithm is used;

[0209] Receive secure account represents the retrieved communication account;

[0210] Perform platform verification processing on the retrieved communication password to obtain the platform password. The method is as follows:

[0211] Platform secure password = Platform validation processing(Receive secure password)

[0212] Among them, Platform secure password represents the platform password;

[0213] Platform validation processing() represents platform verification processing;

[0214] Receive secure password represents the retrieved communication password.

[0215] In the big data blockchain platform, there is an account password verification pair (7A2A317C0784AA0998248138F78AFB8B, F6CA65FC2009C511EF103EE705F2AF62) for login verification. Among them, 7A2A317C0784AA0998248138F78AFB8B is the account stored in the big data blockchain platform, and F6CA65FC2009C511EF103EE705F2AF62 is the password stored in the big data blockchain platform.

[0216] First step, enter the login account dlzh and login password dlmm on the intelligent mobile terminal.

[0217] Second step, after entering the login account dlzh and login password dlmm on the intelligent mobile terminal, assuming the preset account digit number is five digits and the preset password digit number is six digits, the equivalent account and equivalent password can be / dlzh and / / dlmm respectively.

[0218] Third step, perform secure communication processing on the entered login account dlzh and login password dlmm respectively:

[0219] Communications secure account = Secure communication processing(dlzh) = AA5365A0473FF3DC764E0C7BFD41525E,

[0220] Communications secure password=Secure communication processing (dlmm)=6D74F188D458E9606B62996CA78F954D,

[0221] After secure communication processing, the secure communication account AA5365A0473FF3DC764E0C7BFD41525E and the secure communication password 6D74F188D458E9606B62996CA78F954D are obtained respectively;

[0222] Since AA5365A0473FF3DC764E0C7BFD41525E and 6D74F188D458E9606B62996CA78F954D have too many characters and are not conducive to display, the first six characters of each are taken. At this time, the secure communication account and the secure communication password are AA5365 and 6D74F1 respectively. The number of corresponding sequence grids will also change. This embodiment uses the sequence grid as Figure 5 shown: yellow yellow purple orange orange orange purple purple green purple yellow yellow yellow orange yellow orange green green purple green green orange, where the numbers of consecutive non - spaced yellow sequence grids are 2, 3, 1 respectively; the numbers of consecutive non - spaced purple sequence grids are 1, 2, 1, 1 respectively; the numbers of consecutive non - spaced orange sequence grids are 3, 1, 1, 1 respectively; the numbers of consecutive non - spaced yellow sequence grids are 2, 2, 2 respectively.

[0223] Fourth step, put the allele account / dlzh into the purple sequence grid in order from left to right. After putting the allele account / dlzh into the purple sequence grid in order from left to right, it is as Figure 6 shown.

[0224] Fifth step, put the allele password / / dlmm into the green sequence grid in order from left to right. After putting the allele password / / dlmm into the green sequence grid in order from left to right, it is as Figure 7 shown.

[0225] Sixth step, put the secure communication account AA5365 into the yellow sequence grid in order from left to right. After putting the secure communication account AA5365 into the yellow sequence grid in order from left to right, it is as Figure 8 shown.

[0226] Seventh step, put the secure communication password 6D74F1 into the orange sequence grid in order from left to right. After putting the secure communication password 6D74F1 into the orange sequence grid in order from left to right, it is as Figure 9 shown.

[0227] Step 8: Take out all the characters placed in the sequence grid in order from left to right, and the sequence string AA / 6D7dl / / z53645Fdlhmm1 is obtained; transfer the sequence string AA / 6D7dl / / z53645Fdlhmm1 to the big data blockchain platform.

[0228] Step 9: After the big data blockchain platform receives the sequence string AA / 6D7dl / / z53645Fdlhmm1 sent by the intelligent mobile terminal, place the received sequence string AA / 6D7dl / / z53645Fdlhmm1 in the sequence grid as shown in Figure 5 in order from left to right; after placing the received sequence string AA / 6D7dl / / z53645Fdlhmm1 in the sequence grid as shown in Figure 5 it is as shown in Figure 9 .

[0229] Step 10: Take out all the characters placed in the purple sequence grid in order from left to right, and the withdrawn account / dlzh can be obtained; remove the special character / in the withdrawn account / dlzh, and the account to be confirmed dlzh can be obtained;

[0230] Step 11: Take out all the characters placed in the green sequence grid in order from left to right, and the withdrawn password / / dlmm can be obtained; remove the special character / / in the withdrawn password / / dlmm, and the password to be confirmed dlmm can be obtained;

[0231] Step 12: Take out all the characters placed in the yellow sequence grid in order from left to right, and the communication withdrawn account AA5365 can be obtained; in this step, since the first six digits of AA5365A0473FF3DC764E0C7BFD41525E were taken in Step 3, the communication withdrawn account should be regarded as AA5365A0473FF3DC764E0C7BFD41525E.

[0232] Step 13: Take out all the characters placed in the orange sequence grid in order from left to right, and the communication withdrawn password 6D74F1 can be obtained; in this step, since the first six digits of 6D74F188D458E9606B62996CA78F954D were taken in Step 3, the communication withdrawn account should be regarded as 6D74F188D458E9606B62996CA78F954D.

[0233] Step 14: Perform secure communication processing on the account to be confirmed dlzh:

[0234] Judge secure account = Secure communication processing(dlzh) = AA5365A0473FF3DC764E0C7BFD41525E,

[0235] The comparison account AA5365A0473FF3DC764E0C7BFD41525E is obtained after secure communication processing.

[0236] Step 15: Since the comparison account AA5365A0473FF3DC764E0C7BFD41525E is the same as the communication retrieved account AA5365A0473FF3DC764E0C7BFD41525E in Step 12, the account to be confirmed dlzh is the confirmed account dlzh, and the next step is executed;

[0237] Step 16: Perform secure communication processing on the password to be confirmed dlmm:

[0238] Judge secure password = Secure communication processing(dlmm) = 6D74F188D458E9606B62996CA78F954D,

[0239] The comparison password 6D74F188D458E9606B62996CA78F954D is obtained after secure communication processing.

[0240] Step 17: Since the comparison password 6D74F188D458E9606B62996CA78F954D is the same as the communication retrieved password 6D74F188D458E9606B62996CA78F954D in Step 13, the password to be confirmed dlmm is the confirmed password dlmm, and the next step is executed;

[0241] Step 18: Perform platform verification processing on the obtained communication retrieved account AA5365A0473FF3DC764E0C7BFD41525E and communication retrieved password 6D74F188D458E9606B62996CA78F954D respectively:

[0242] Platform secure account = Platform validation processing(AA5365A0473FF3DC764E0C7BFD41525E) = 7A2A317C0784AA0998248138F78AFB8B,

[0243] Platform secure password = Platform validation processing(6D74F188D458E9606B62996CA78F954D) = F6CA65FC2009C511EF103EE705F2AF62,

[0244] After the platform validation processing, the platform account 7A2A317C0784AA0998248138F78AFB8B and the platform password F6CA65FC2009C511EF103EE705F2AF62 are obtained respectively.

[0245] Step 19: Since the platform account 7A2A317C0784AA0998248138F78AFB8B exists in the big data blockchain platform, the password corresponding to the platform account 7A2A317C0784AA0998248138F78AFB8B is extracted as F6CA65FC2009C511EF103EE705F2AF62.

[0246] Step 20: Since the platform password F6CA65FC2009C511EF103EE705F2AF62 is the same as the password F6CA65FC2009C511EF103EE705F2AF62 corresponding to the extracted platform account 7A2A317C0784AA0998248138F78AFB8B, the intelligent mobile terminal logs in to the big data blockchain platform.

[0247] Another implementation step: Step 1, enter the login account dlzh and the login password dlmm on the intelligent mobile terminal.

[0248] Step 2, after entering the login account dlzh and the login password dlmm on the intelligent mobile terminal, assuming that the preset account digit number is five digits and the preset password digit number is six digits, the equivalent account and the equivalent password can be / dlzh and / / dlmm respectively.

[0249] Step 3, perform secure communication processing on the entered login account dlzh and the login password dlmm respectively:

[0250] Communications secure account = Secure communication processing(dlzh) = AA5365A0473FF3DC764E0C7BFD41525E,

[0251] Communications secure password=Secure communication processing(dlmm)=6D74F188D458E9606B62996CA78F954D,

[0252] After secure communication processing, the secure communication account AA5365A0473FF3DC764E0C7BFD41525E and the secure communication password 6D74F188D458E9606B62996CA78F954D are obtained respectively;

[0253] Since AA5365A0473FF3DC764E0C7BFD41525E and 6D74F188D458E9606B62996CA78F954D have too many characters and are not conducive to display, the first six digits of each are taken. At this time, the secure communication account and the secure communication password are AA5365 and 6D74F1 respectively. The number of corresponding sequence grids will also change. This embodiment uses the sequence grids as Figure 10 shown: yellow purple purple orange orange orange yellow purple green green purple yellow purple orange orange yellow orange green green yellow green yellow, where the numbers of consecutive non - spaced yellow sequence grids are 1, 1, 1, 1, 1, 1 respectively; the numbers of consecutive non - spaced purple sequence grids are 2, 1, 1, 1 respectively; the numbers of consecutive non - spaced orange sequence grids are 3, 2, 1 respectively; the numbers of consecutive non - spaced yellow sequence grids are 2, 2, 2 respectively.

If two equal random numbers are smaller than the other two random numbers, then the two equal random numbers are not the smallest random numbers. For example, if Random11 = Random21 < Random31 < Random11, then Random11 or Random21 is not the smallest random number; if three equal random numbers are smaller than another random number, then the three equal random numbers are not the smallest random numbers. For example, if Random11 = Random21 = Random31 < Random41, then Random11 or Random21 or Random31 is not the smallest random number; if four random numbers are equal, then these four random numbers are not the smallest random numbers.

[0329] Step 11. Take out all the characters in the green sequence grid from left to right to get the password / / dlmm. Remove the special characters / / in the password / / dlmm to get the password to be confirmed dlmm.

[0330] In the twelfth step, take out all the characters put into the yellow sequence grid in order from left to right to get the communication withdrawal account number AA5365. In this step, since the first six digits of AA5365A0473FF3DC764E0C7BFD41525E were taken in the third step, the communication withdrawal account number should be regarded as AA5365A0473FF3DC764E0C7BFD41525E.

[0331] Step 13. Take out all the characters in the orange sequence grid in order from left to right to get the communication withdrawal password 6D74F1. In this step, since the first six digits of 6D74F188D458E9606B62996CA78F954D were taken in the third step, the communication withdrawal account number should be regarded as 6D74F188D458E9606B62996CA78F954D.

[0337] Judge secure password = Secure communication processing(dlmm) = 6D74F188D458E9606B62996CA78F954D,

[0338] After secure communication processing, the comparison password 6D74F188D458E9606B62996CA78F954D is obtained.

[0339] Step 17: Since the comparison password 6D74F188D458E9606B62996CA78F954D is the same as the communication retrieval password 6D74F188D458E9606B62996CA78F954D in Step 13, the password to be confirmed dlmm is the confirmed password dlmm, and proceed to the next step;

[0356] S17. Take the rotation angle corresponding to the shortest perimeter as the determined K-sided polygon; at this time, the K intersection points corresponding to the K-sided polygon are the preset position information, that is, in clockwise order, they are the first intersection point, the second intersection point, the third intersection point,..., the Kth intersection point corresponding to the preset positions P1, preset position P2, preset position P3,..., preset position P K .
