Technical Field

[0001] This application belongs to the field of data processing technology, and in particular relates to a data storage method, apparatus, device and computer-readable storage medium. Background Technology

[0002] With the ever-increasing volume of data, storage is required in various scenarios. Improving data storage security has become one of the key issues to be addressed in data storage.

[0003] In existing technologies, after acquiring data, the device typically stores the data in a database in the form of a structured table, and then retrieves and queries the data using SQL queries when needed.

[0004] While database services offer the advantage of high efficiency for users, they are also vulnerable to attacks such as SQL injection, which can lead to data leaks and compromise data storage security. Summary of the Invention

[0005] This application provides a data storage method, apparatus, device, and computer-readable storage medium that can improve the security of data storage.

[0006] In a first aspect, embodiments of this application provide a data storage method, the method comprising:

[0007] Acquire target data, which includes multiple pages of data;

[0008] Each page of data in the multi-page data is encrypted separately to obtain multiple encrypted information corresponding to the multi-page data;

[0009] The multiple encrypted information are concatenated to obtain the target encrypted information corresponding to the target data;

[0010] Store the target encrypted information.

[0011] Secondly, embodiments of this application provide a data storage device, the device comprising:

[0020] The data storage method, apparatus, device, and computer-readable storage medium in this application improve data security by encrypting each page of data in a multi-page dataset separately.

[0027] The features and exemplary embodiments of various aspects of this application will be described in detail below. To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain this application and not to limit it. For those skilled in the art, this application can be implemented without some of these specific details. The following description of the embodiments is merely to provide a better understanding of this application by illustrating examples.

[0028] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising..." does not exclude the presence of additional identical elements in the process, method, article, or apparatus that includes said element.

[0029] In existing technologies, after acquiring data, devices typically store it in a database in the form of structured tables, and then use SQL statements to retrieve the data. However, the process of using SQL statements to query data is vulnerable to attacks such as SQL injection, leading to data leakage and thus resulting in low data storage security.

[0030] To address the problems of the prior art, embodiments of this application provide a data storage method, apparatus, device, and computer-readable storage medium. The data storage method provided in this application embodiment is described first below.

[0031] Figure 1 This is a schematic flowchart of a data storage method provided in one embodiment of this application. Figure 1 As shown, this data storage method may specifically include the following steps:

[0032] S110. Obtain the target data, which includes multiple pages of data;

[0033] S120. Encrypt each page of data in the multi-page data separately to obtain multiple encrypted messages corresponding to the multi-page data;

[0034] S130. Concatenate multiple encrypted messages to obtain target encrypted information corresponding to the target data;

[0035] S140, Store target encrypted information.

[0036] Therefore, by encrypting each page of data in a multi-page dataset separately, data security can be improved. By concatenating the encrypted information, the target encrypted information is obtained, making it easier to store. Based on this, storing the target encrypted information in an unstructured manner can avoid the impact of attacks such as SQL injection, thereby improving data storage security.

[0037] The specific implementation methods for each of the above steps are described below.

[0038] In some implementations, in S110, the target data can be any data acquired by the device, and all or part of the data in the target data may need to be encrypted. Furthermore, the target data can be multi-page data, i.e., data from multiple data pages, with each data page containing multiple data entries. Here, the target data may, for example, include transaction log data.

[0039] Taking the target data as data retrieved from a server or other device as an example, in some specific cases, if the amount of data queried by the user exceeds the amount of data that can be included in each data page, the target data can include multiple pages of data. For example, if the user queries 50 records of data, and each page can include 20 records, then the target data can include 3 pages of data.

[0040] Therefore, in order to obtain the target data, in some embodiments, the above-mentioned S110 may specifically include:

[0041] Send a data query request to the target server. The data query request includes data query conditions. The data query request is used to instruct the target server to retrieve the target data according to the data query conditions.

[0042] Receive the target data returned by the target server.

[0043] Here, taking a batch query scenario of bank transaction records as an example, the data query conditions can be, for example, company name, transaction time, transaction method, identity identifier, bank card number, etc. The target server can be the bank's server.

[0044] As an example, after the target server receives a data query request from the user's electronic device, it can query the target data that meets the requirements based on the data query conditions in the request. After retrieving the target data, the target server can determine whether pagination is needed based on pre-set pagination rules. If pagination is needed, it can perform pagination according to the preset rules, obtaining multiple pages of data, and returning these multiple pages to the user. Conversely, if pagination is not needed, a single page of data can be returned to the user.

[0045] In this way, the target data can be obtained by sending a data query request to the target server.

[0046] To enable the target server to paginate the target data according to pagination rules and obtain multiple pages of data, in some embodiments, the data query request may also include pagination rule information. Based on this, before sending the data query request to the target server, the following may also be included:

[0047] Receives a second input from the user to specify pagination rules;

[0048] In response to the second input, pagination rule information is generated. The pagination rule information is used to instruct the target server to process the target data into multiple pages according to the pagination rules.

[0049] Here, pagination rules can be based on factors such as data volume, time, location, and company name. If the pagination rule is based on data volume, it could be set to include n records per page, or n rows per page, where n can be a positive integer. If the pagination rule is based on time, it could be set to have one page corresponding to one month's data, or one page corresponding to one day's data, etc.

[0050] As an example, if the data query request includes pagination rule information, the target server can process the target data into multiple pages according to the pagination rule information in the data query request.

[0051] As another example, if the data query request does not include pagination rule information, the target server can paginate the target data according to the preset pagination rules to obtain multiple pages of data.

[0052] In this way, by responding to the second input used by the user to formulate pagination rules, pagination rule information is generated, enabling the target server to paginate the target data according to the pagination rules and obtain multiple pages of data.

[0053] In some implementations, in S120, a page of data can be encrypted to obtain encrypted information. The encrypted information can be a string of numbers, a string of letters, or a string composed of a mixture of numbers and letters. For example, the encrypted information can be represented as "ed64".

[0054] In some implementations, in S130, the target encrypted information can be formed by concatenating multiple encrypted information obtained from encrypting multiple pages of data.

[0055] In some specific examples, if the target data includes three pages of data, and the three encrypted messages corresponding to the three pages are "ed64", "ee35", and "674f" respectively, then the target encrypted message can be "ed64ee35674f". The encrypted message can be concatenated according to the page order or other rules.

[0056] In some embodiments, in S140, the target encrypted information can be stored after it is obtained.

[0057] Therefore, in order to facilitate the storage of encrypted data and further improve the security of stored data, in some embodiments, the above-mentioned S140 may specifically include:

[0058] Write the target encrypted information into the target file;

[0059] Store the target file.

[0060] Here, by writing the target encrypted information into a file and storing the target data in file form, compared to storing it in a database, it can avoid the impact of attack methods such as SQL injection, making it less susceptible to attack and thus further improving the security of the stored data.

[0061] Therefore, in order to accurately locate each page of data in a multi-page dataset while the data is encrypted, some implementations may include the following steps before storing the target file:

[0062] Write the page number information of the data page corresponding to each of the multiple encrypted messages, as well as the index position information of each of the multiple encrypted messages in the target encrypted message, into the target file.

[0063] Here, each encrypted message can correspond to a page number. Additionally, each encrypted message in the target encrypted information can correspond to an index position. This index position can include the start and end positions of the encrypted message. Thus, by using the index position information corresponding to each encrypted message, the position of each encrypted message within the target encrypted information can be quickly and accurately located, enabling rapid indexing and decryption when viewing the original data corresponding to each encrypted message later.

[0064] Therefore, when both the page number information and the index position information are written into the target file, the concatenation order of multiple encrypted information in the target encrypted information is not restricted.

[0065] In this way, by writing the page number information and index position information into the target file, it is possible to accurately locate each page of data in a multi-page dataset even with data encryption.

[0066] Therefore, in order to enable users to view the encrypted target data, in some embodiments, after storing the target file, the following may also be included:

[0067] Receive the user's first input for viewing the target data;

[0068] In response to the first input, read the target encryption information, page number information, and index position information from the target file;

[0069] Based on the index position information, the target encrypted information is split into multiple encrypted information;

[0070] Multiple encrypted messages are decrypted to obtain multiple pages of data;

[0071] Arrange and display data from multiple pages according to page number information.

[0072] Here, since the target data has been encrypted, in response to the user's first input to view the target data, the encrypted information can be split and decrypted to restore the target data.

[0073] In this way, by decrypting the target encrypted information based on page number information and index position information, and arranging and displaying multi-page data, users can view the encrypted target data.

[0074] To further improve the security of stored data, as another implementation of this application, this application also provides another implementation of the data storage method, as detailed in the following embodiments.

[0075] Please see Figure 2Another implementation of the data storage method provided in this application includes steps S210-S250, the specific steps of which are shown below.

[0076] S210. Obtain the target data, which includes multiple pages of data.

[0077] S220. According to the preset desensitization rules, each page of data in the multi-page data is desensitized separately to hide the sensitive data in the target data, and the desensitized multi-page data is obtained.

[0078] Here, sensitive data can be users' private data, such as names, ID card numbers, bank card numbers, etc. An anonymized ID card number could be displayed as, for example, "310*********0515**".

[0079] Based on this, sensitive data in the target data can be de-identified according to preset de-identification rules. These preset de-identification rules can be pre-defined fields belonging to sensitive data, along with specific de-identification methods, including but not limited to replacing sensitive data with preset characters.

[0080] For example, information recognition technology can be used on the target data to obtain the data corresponding to the fields that belong to sensitive data in the target data, and then each character in these data can be replaced with an asterisk (*) to complete the desensitization process.

[0081] S230. Encrypt each page of data in the multi-page data separately to obtain multiple encrypted messages corresponding to the multi-page data.

[0082] S240. Concatenate multiple encrypted messages to obtain target encrypted information corresponding to the target data.

[0083] S250, Store target encrypted information.

[0084] It should be noted that S210 is the same as S110 in the above embodiment, and S230 to S250 are the same as S120 to S140 in the above embodiment. For the sake of brevity, they will not be described in detail here.

[0085] Therefore, by desensitizing each page of data in a multi-page dataset, sensitive data within the target data can be hidden, further enhancing data storage security.

[0086] To better describe the overall solution, some specific examples are given based on the above embodiments.

[0087] For example, such as Figure 3 The flowchart illustrates a data storage method. This data storage method may include steps S310-S350, which will be explained in detail below.

[0088] S310. Obtain the target data, which includes multiple pages of data;

[0089] S320. Perform sensitive data desensitization on each page of data;

[0090] S330, Data encryption, obtaining encrypted information;

[0091] S340. Determine if there is an unencrypted data page. If yes, proceed to S320; otherwise, proceed to S350.

[0092] S350. Multiple encrypted information are concatenated to obtain target encrypted information corresponding to the target data.

[0093] In some specific examples, when the target data consists of multiple pages, each page can be processed separately. The processing order can be to first de-identify and encrypt one page, then perform the same de-identification and encryption on the next page, and so on, until all pages have been processed. Finally, the encrypted information can be concatenated to obtain the target encrypted information corresponding to the target data. The processing order for multiple pages is not limited.

[0094] In other specific examples, multiple pages of data can be anonymized and encrypted in parallel.

[0095] Therefore, by performing anonymization and encryption on each page of multi-page data separately, data security can be improved. By concatenating the encrypted information, the target encrypted information is obtained, making it easier to store. Based on this, storing the target encrypted information in an unstructured manner can avoid the impact of attacks such as SQL injection, thereby improving data storage security.

[0096] In addition, let's take the scenario of batch querying bank transaction records as an example to give some more examples.

[0097] In some examples, the electronic device can send a transaction history query request to a transaction history query interface provided by the bank. This request can include query conditions and other information, allowing the bank's server to retrieve the corresponding transaction history data based on these conditions. After retrieving the transaction history data, the bank's server can paginate the data according to preset or user-defined pagination rules, resulting in multiple pages of transaction history data. The bank's server can then perform de-identification and encryption processing on each page of transaction history data, obtaining encrypted information corresponding to each page. This encrypted information is then returned to the electronic device through the transaction history query interface. Upon receiving the encrypted information returned by the transaction history query interface, the electronic device can concatenate the multiple encrypted information retrieved and write it to a file for data storage.

[0098] In other examples, the bank's server can also directly return the multi-page transaction data to the electronic device through the transaction query interface. The electronic device will then de-identify and encrypt the multi-page transaction data, and concatenate the multiple encrypted messages before writing them into a file for data storage.

[0099] It should be noted that the application scenarios described in the above embodiments of this application are for the purpose of more clearly illustrating the technical solutions of the embodiments of this application, and do not constitute a limitation on the technical solutions provided by the embodiments of this application. As those skilled in the art will know, with the emergence of new application scenarios, the technical solutions provided by the embodiments of this application are also applicable to similar technical problems.

[0100] Based on the same inventive concept, this application also provides a data storage device. (Specifically combined with...) Figure 4 Please provide a detailed explanation.

[0124] In some embodiments, the data query request may further include pagination rule information. Based on this, the acquisition module 410 may further include:
