Description

[0001] This application is a divisional application of application number 2024106066720, application date May 15, 2024, entitled "Method for Securely Downloading Private Massive Data from Big Data Blockchain Cloud Platform". Technical Field

[0002] This invention relates to the field of critical data security technology, and in particular to a method for securely downloading massive amounts of private data through a big data blockchain cloud platform. Background Technology

[0003] With the rapid development and popularization of cloud storage technology, more and more mobile platform users like to quickly upload photos, videos, or personal logs taken with their mobile phones or tablets to cloud storage. This allows for very quick retrieval of photos and logs remotely or even instantly via a web or PC client. However, each user's photo or other file may be stolen during the upload process. Patent application number 2014100071721, entitled "A Method for Uploading and Access Control of Cloud Data," discloses a method that includes a server receiving and storing cloud data with security levels. Upon receiving a cloud data access request, the server performs key authentication on the accessing user. If the key authentication is successful, the server allows the accessing user to read and write the cloud data. Otherwise, the server performs password authentication on the accessing user. If the password authentication is successful, the server obtains the security level corresponding to the cloud data. If the security level is ordinary, the server allows the accessing user to read and write the cloud data. If the security level is important, the server allows the accessing user to read-only access the cloud data. If the security level is confidential, the server rejects the access request. Because the cloud data in this invention has corresponding security levels, users can only operate on cloud data of different security levels within their own permission scope, thereby enhancing the security and privacy of cloud data access. Summary of the Invention

[0004] This invention aims to at least solve the technical problems existing in the prior art, and in particular, innovatively proposes a method for securely downloading private massive amounts of data through a big data blockchain cloud platform.

[0399] 0a1eb5a1*8fe8dff*ec**5f471412718a74f376f7a4 and SMS receiving code dxm9.

[0400] Step 20: Place the received mobile phone number 0a1eb5a1*8fe8dff*ec**5f471412718a74f376f7a4 into the squares in order from left to right, as follows: Figure 4 As shown.

[0401] Step 21: Extract the characters from the blue squares in order from left to right to obtain the platform's mobile number 151****1234; extract the characters from the red squares in order from left to right to obtain the platform's string.

[0402] 0aeba8fe8dffec5f4714718a74f76f7a; Clear the characters in the squares of this step for later use.

[0403] Step 22: Using the platform's mobile number processing method, process the platform's mobile number 151****1234 to obtain the platform's processed string:

[0404] platformstring=platformnumbermethod(platformID)

[0405] =platformnumbermethod(151****1234)

[0406] =0aeba8fe8dffec5f4714718a74f76f7a;

[0407] The string 0aeba8fe8dffec5f4714718a74f76f7a is the character platform processing string.

[0408] Step 23: Since the character platform processing string 0aeba8fe8dffec5f4714718a74f76f7a in step 22 is the same as the platform string 0aeba8fe8dffec5f4714718a74f76f7a in step 23, proceed to the next step.

[0409] Step 24: Use the SMS receiving code dxm9 to retrieve the stored mobile phone number, and determine whether the mobile phone number retrieved using the SMS receiving code dxm9 matches the platform mobile phone number 151****1234 in Step 21:

[0410] Since the mobile phone number obtained by querying using the SMS receiving code dxm9 matches the platform mobile phone number 151****1234 in step 21, the login to the big data platform is successful.

[0411] If the mobile phone number obtained by querying using the SMS receiving code dxm9 does not match the platform mobile phone number 151****1234 in step 21, then logging into the big data platform will fail.

[0412] Alternatively, the first step is for the user to enter their mobile number 151****1234 into the mobile number input box. After entering the mobile number 151****1234, the user clicks "Get SMS code".

[0413] The second step involves the smart mobile handheld terminal receiving a "Get SMS code" trigger signal. After receiving the "Get SMS code" trigger signal, the smart mobile handheld terminal obtains the mobile phone number 151****1234 entered by the user in the mobile phone number input box.

[0414] The third step is to use the phone number processing method on the phone number 151****1234 to obtain the character string:

[0415] Characterstring=Phonenumbermethod(151****1234)

[0416] =Phonenumbermethod(PhoneID)

[0417] =0aeba8fe8dffec5f4714718a74f76f7a,

[0418] The string 0aeba8fe8dffec5f4714718a74f76f7a is the character processing string.

[0419] The fourth step is to place the string "0aeba8fe8dffec5f4714718a74f76f7a" into the red squares in order from left to right, as shown below. Figure 3 As shown.

[0420] Step 5: Place the phone number 151****1234 into the blue squares in order from left to right; for example... Figure 4 As shown.

[0421] Step 6: Take out the characters from the squares in order from left to right; this gives the phone processing number 0a1eb5a1*8fe8dff*ec**5f471412718a74f376f7a4. For ease of calculation, **** is 8888, so the phone processing number is 0a1eb5a188fe8dff8ec885f471412718a74f376f7a4. Clear the characters in the squares from this step for later use.

[0422] Step 7: Convert the phone processing number 0a1eb5a188fe8dff8ec885f471412718a74f376f7a4 (considered hexadecimal) to a decimal phone processing number. The decimal phone processing number is 0236645385648151624533010091840487131698465477162916; then convert the decimal phone processing number 023664... 5385648151624533010091840487131698465477162916 is converted into a sixty-binary mobile phone processing number, which is 01xorGEKuROe0Hf6z7c1DFRtA2jRNG; the sixty-binary mobile phone processing number 01xorGEKuROe0Hf6z7c1DFRtA2jRNG is then sent to the big data platform.

[0423] Step 8: After receiving the mobile processing number 01xorGEKuROe0Hf6z7c1DFRtA2jRNG sent by the smart mobile handheld terminal, the big data platform obtains the mobile receiving number 01xorGEKuROe0Hf6z7c1DFRtA2jRNG.

[0424] Step 9: Convert the mobile phone receiving number 01xorGEKuROe0Hf6z7c1DFRtA2jRNG into a decimal mobile phone processing number, which is 0236645385648151624533010091840487131698465477162916. Then convert the decimal mobile phone processing number into a hexadecimal mobile phone processing number, which is 0a1eb5a188fe8dff8ec885f471412718a74f376f7a4.

[0425] Step 10: Place the phone processing number 0a1eb5a188fe8dff8ec885f471412718a74f376f7a4 into the squares in order from left to right, as follows: Figure 4 As shown.

[0426] Step 11: Take out the characters from the blue squares in order from left to right. To be consistent with step 6, 8888 is replaced with ****, which gives us the platform's mobile number 151****1234. Clear the characters in the squares in this step for later use.

[0427] Step 12: The big data platform generates an SMS code (e.g., dxm9), and stores the SMS code dxm9 and the platform's mobile number 151****1234 as a query pair in the big data platform for subsequent queries; then, the SMS code dxm9 is sent to the platform's mobile number 151****1234.

[0428] Step 13: After receiving the SMS code dxm9 via a smart mobile handheld terminal, the user enters the SMS code dxm9 into the SMS code input box and then clicks "Login".

[0429] Step 14: At this time, the smart mobile handheld terminal receives the "login" trigger signal. After receiving the "login" trigger signal, the smart mobile handheld terminal obtains the mobile phone number 151****1234 entered by the user in the mobile phone number input box and the SMS code dxm9 entered in the SMS code input box.

[0430] Step 15: Using the phone number processing method, process the phone number 151****1234 to obtain the character string:

[0431] Characterstring=Phonenumbermethod(151****1234)

[0432] =Phonenumbermethod(PhoneID)

[0433] =0aeba8fe8dffec5f4714718a74f76f7a,

[0434] The string 0aeba8fe8dffec5f4714718a74f76f7a is the character processing string.

[0435] Step sixteen: Place the string 0aeba8fe8dffec5f4714718a74f76f7a into the red squares in order from left to right, as follows: Figure 3 As shown.

[0436] Step 17: Place the phone number 151****1234 into the blue squares in order from left to right; for example... Figure 4As shown; for ease of calculation, **** is 8888, which is the mobile phone processing number 0a1eb5a188fe8dff8ec885f471412718a74f376f7a4 (considered as hexadecimal).

[0437] Step 18: Extract the characters from the squares sequentially from left to right; this yields the phone processing number 0a1eb5a188fe8dff8ec885f471412718a74f376f7a4. Clear the characters from the squares in this step for later use. Convert the phone processing number 0a1eb5a188fe8dff8ec885f471412718a74f376f7a4 into a decimal phone processing number. The decimal phone processing number is... 0236645385648151624533010091840487131698465477162916; then convert the decimal mobile phone processing number 0236645385648151624533010091840487131698465477162916 into a hexadecimal mobile phone processing number, which is 01xorGEKuROe0Hf6z7c1DFRtA2jRNG.

[0438] Step 19: Send the mobile phone processing number 01xorGEKuROe0Hf6z7c1DFRtA2jRNG and the SMS code dxm9 to the big data platform.

[0439] Step 20: After receiving the mobile processing number 01xorGEKuROe0Hf6z7c1DFRtA2jRNG and SMS code dxm9 from the smart mobile handheld terminal, the big data platform obtains the mobile receiving number 01xorGEKuROe0Hf6z7c1DFRtA2jRNG and SMS receiving code dxm9.

[0440] Step 21: Convert the mobile phone receiving number 01xorGEKuROe0Hf6z7c1DFRtA2jRNG into a decimal mobile phone processing number, which is 0236645385648151624533010091840487131698465477162916. Then convert the decimal mobile phone processing number into a hexadecimal mobile phone processing number, which is 0a1eb5a188fe8dff8ec885f471412718a74f376f7a4.

[0441] Step 22: Place the received mobile phone number 0a1eb5a188fe8dff8ec885f471412718a74f376f7a4 into the squares in order from left to right, as follows: Figure 4 As shown. Leading zeros should be retained before number system conversion and / or in the result obtained using the MD5 digest algorithm.

[0442] Step 23: Take out the characters from the blue squares in order from left to right. To be consistent with step 17, 8888 is replaced with ****, which gives us the platform's mobile number 151****1234. Clear the characters in the squares in this step for later use.

[0443] Step 24: Use the SMS receiving code dxm9 to retrieve the stored mobile phone number, and determine whether the mobile phone number retrieved using the SMS receiving code dxm9 matches the platform mobile phone number 151****1234 in Step 23:

[0444] Since the mobile phone number obtained by querying using the SMS receiving code dxm9 matches the platform mobile phone number 151****1234 in step 23, the login to the big data platform is successful.

[0445] If the mobile phone number obtained by querying using the SMS receiving code dxm9 does not match the platform mobile phone number 151****1234 in step 23, then logging into the big data platform will fail.

[0505] S911, the intelligent mobile handheld terminal requests the asymmetric public key Asymmetricpublickey from the big data platform. The big data platform stores U pairs of asymmetric key pairs, where U is a positive integer greater than or equal to 1, namely the 1st asymmetric key pair, the 2nd asymmetric key pair, the 3rd asymmetric key pair, ..., the Uth asymmetric key pair. The uth asymmetric key pair includes the asymmetric public key Asymmetricpublickeyu and the asymmetric private key Asymmetricprivatekeyu, where u is a positive integer less than or equal to U. That is, the 1st asymmetric key pair includes the asymmetric public key Asymmetricpublickey1 and the asymmetric private key Asymmetricprivatekey1, the 2nd asymmetric key pair includes the asymmetric public key Asymmetricpublickey2 and the asymmetric private key Asymmetricprivatekey2, the 3rd asymmetric key pair includes the asymmetric public key Asymmetricpublickey3 and the asymmetric private key Asymmetricprivatekey3, and the Uth asymmetric key pair includes the asymmetric public key AsymmetricpublickeyU and the asymmetric private key AsymmetricprivatekeyU.

[0506] S912, after receiving the asymmetric public key request from the smart mobile handheld terminal, the big data platform randomly selects a pair of asymmetric key pairs (e.g., the first asymmetric key pair) and sends the asymmetric public key Asymmetricpublickey1 to the smart mobile handheld terminal.

[0507] S913, after the smart mobile handheld terminal receives the asymmetric public key Asymmetricpublickey1 sent by the big data platform, the smart mobile handheld terminal generates a symmetric key symmetrickey; the symmetric key symmetrickey is stored in the smart mobile handheld terminal for subsequent encryption;

[0508] S914, after the intelligent mobile handheld terminal generates a symmetric key symmetrickey, it uses the asymmetric public key Asymmetricpublickey1 to perform asymmetric encryption on the symmetric key symmetrickey to obtain the encrypted symmetric key symmetrickey. After obtaining the encrypted symmetric key symmetrickey, the intelligent mobile handheld terminal sends the encrypted symmetric key symmetrickey to the big data platform.

[0509] S915 After receiving the encrypted symmetric key symmetrickey sent by the smart mobile handheld terminal, the big data platform uses the asymmetric private key Asymmetricprivatekey1 to decrypt the received encrypted symmetric key symmetrickey. After decryption, the symmetric key symmetrickey is obtained. At this time, the big data platform generates a query identifier QueryID.

[0510] S916 After the big data platform generates a query ID, it stores the query ID and the symmetric key to form a query pair for subsequent queries to obtain the symmetric key using the query ID; the query ID is symmetrically encrypted using the symmetric key to obtain the encrypted query ID, and the big data platform sends the encrypted query ID to the smart mobile handheld terminal.

[0511] S917: After receiving the encrypted query flag QueryID sent by the big data platform, the intelligent mobile handheld terminal uses the symmetric key to symmetrically decrypt the received encrypted query flag QueryID to obtain the query flag QueryID.

[0512] In a preferred embodiment of the present invention, the symmetric key in step S92 is generated in step S913.

[0513] In a preferred embodiment of the present invention, the symmetric key obtained in step S93 is the same as the symmetric key in the query pair in step S916.

[0514] In this embodiment, the method for downloading private chat data stored on a big data platform to a smart mobile handheld terminal includes the following steps:

[0515] S81, the big data platform uses a symmetric key (symmetrickey) to symmetrically encrypt the private chat data to be downloaded on the smart mobile handheld terminal, thus obtaining encrypted chat data; the big data platform then sends the encrypted chat data to the smart mobile handheld terminal.

[0516] After receiving encrypted chat data from a big data platform, the S82 smart mobile handheld terminal uses a symmetric key (symmetrickey) to decrypt the encrypted chat data, obtaining the private chat data. This private chat data can then be viewed. The symmetric key (symmetrickey) and asymmetric key are updated periodically, typically once a day or once an hour.

[0517] In a preferred embodiment of the present invention, step S81, the method for obtaining the symmetric key stored in the big data platform includes the following steps:

[0518] S81, the intelligent mobile handheld terminal requests the asymmetric public key Asymmetricpublickey from the big data platform. The big data platform stores U pairs of asymmetric keys, where U is a positive integer greater than or equal to 1, namely the 1st asymmetric key pair, the 2nd asymmetric key pair, the 3rd asymmetric key pair, ..., the Uth asymmetric key pair. The uth asymmetric key pair includes the asymmetric public key Asymmetricpublickeyu and the asymmetric private key Asymmetricprivatekeyu, where u is a positive integer less than or equal to U. That is, the 1st asymmetric key pair includes the asymmetric public key Asymmetricpublickey1 and the asymmetric private key Asymmetricprivatekey1, the 2nd asymmetric key pair includes the asymmetric public key Asymmetricpublickey2 and the asymmetric private key Asymmetricprivatekey2, the 3rd asymmetric key pair includes the asymmetric public key Asymmetricpublickey3 and the asymmetric private key Asymmetricprivatekey3, and the Uth asymmetric key pair includes the asymmetric public key AsymmetricpublickeyU and the asymmetric private key AsymmetricprivatekeyU.

[0519] S912, after receiving the asymmetric public key request from the smart mobile handheld terminal, the big data platform randomly selects a pair of asymmetric key pairs (e.g., the first asymmetric key pair) and sends the asymmetric public key Asymmetricpublickey1 to the smart mobile handheld terminal.

[0520] S913, after the smart mobile handheld terminal receives the asymmetric public key Asymmetricpublickey1 sent by the big data platform, the smart mobile handheld terminal generates a symmetric key symmetrickey and stores it in the smart mobile handheld terminal for subsequent decryption;

[0521] S914, after the intelligent mobile handheld terminal generates a symmetric key symmetrickey, it uses the asymmetric public key Asymmetricpublickey1 to perform asymmetric encryption on the symmetric key symmetrickey to obtain the encrypted symmetric key symmetrickey. After obtaining the encrypted symmetric key symmetrickey, the intelligent mobile handheld terminal sends the encrypted symmetric key symmetrickey to the big data platform.

[0522] In S915, after receiving the encrypted symmetric key (symmetrickey) sent by the smart mobile handheld terminal, the big data platform decrypts the received encrypted symmetric key (symmetrickey) using the asymmetric private key (Asymmetricprivatekey1), obtaining the symmetric key (symmetrickey). The symmetric key (symmetrickey) is stored in the big data platform and used to encrypt the private chat data to be downloaded, preventing leakage of the private chat data if intercepted during the download process.

[0523] In this embodiment, after logging into the big data platform, the method further includes using blockchain to realize decentralized buying and selling of goods through the big data platform. The method for realizing decentralized buying and selling of goods through blockchain via the big data platform includes the following steps:

[0524] S61, the big data platform obtains information on the goods purchased by the buyer, which includes one or any combination of the product name, order serial number, and order payment serial number; the big data platform sends the information on the goods purchased by the buyer to the blockchain;

[0525] S62, the big data platform obtains information on goods shipped by the seller, including the product name, buyer order serial number, buyer order payment serial number, and express tracking number, or any combination thereof; the big data platform sends the obtained information on goods shipped by the seller to the blockchain.
