[0038] To facilitate understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant accompanying drawings. Several embodiments of the present invention are given in the accompanying drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0039] Please refer to Figure 1, which shows a flowchart of a data storage method provided by an embodiment of the present invention.

[0040] As Figure 1 shown, the data storage method includes steps S01 to S06.

[0041] Step S01, obtain a data set, where the data set contains at least one data information string.

[0042] Step S02, determine whether the length of the at least one data information string exceeds a preset length.

[0043] In specific implementation, by determining whether the length of the at least one data information string exceeds the preset length, it is possible to pre-determine whether the length of the at least one data information string to be processed is suitable for subsequent operations. When the length of the at least one data information string to be processed is less than the preset length, it means that the length of the at least one data information string to be processed is too short, so that the subsequent sliding of the preset first character window cannot selectively frame the at least one data information string to be processed. For example: the length of a certain data information string to be processed is 5 bytes, and the set preset length is 10 bytes. If a first character window with a length of 6 bytes is directly used to frame the 5-byte data information string, then the data information string will be completely framed by the first character window at the first time, and the unframed data information character segment cannot be obtained.

[0044] It should be noted that the length of the first character window is randomly set and its length is less than the preset length. However, when the length of the first character window is too short, it will increase the amount of data to be processed subsequently. Therefore, in order to improve the efficiency of data processing, the length of the first character window should not be set too short.

[0045] Specifically, for the case where the length of the data information string does not exceed the preset length, the method adopted in this embodiment is: if the length of the at least one data information string does not exceed the preset length, then insert a preset interval character at any position of the at least one data information string until the length of the at least one data information string exceeds the preset length.

[0046] Step S03, if the length of the at least one data information string exceeds the preset length, then slide the preset first character window to frame the data information characters in the at least one data information string, and obtain at least one framed data information character segment and at least one unframed data information character segment.

[0047] In specific implementation, the sliding rule of the first character window is that the sliding distance of the first character window is random and the sliding distance is greater than the length of the first character window.

[0048] Specifically, by adopting the method of randomly sliding the first character window, when the first character window frames the data information string, unframed data information character segments with inconsistent lengths and framed data information character segments with consistent lengths can be obtained, achieving the purpose of irregular segmentation of the data information string.

[0049] In a specific embodiment, as Figure 2 shown, a first character window with a length of 4 bytes slides on a certain data information string to be processed. The sliding distance for the first time is 7 bytes, the sliding distance for the second time is 8 bytes, and the sliding distance for the third time is 9 bytes, so as to obtain unframed data information character segments with different lengths.

[0050] Step S04: Associate at least one unframed data information character segment with a preset interval character segment, and splice the preset interval character segment with at least one framed data information character segment based on the positional relationship between at least one framed data information character segment and at least one unframed data information character segment to form at least one target data information string.

[0051] In specific implementation, obtain a preset interval character segment, where the length of the preset interval character segment is equal to the length of at least one unframed data information character segment, and associate at least one unframed data information character segment with the preset interval character segment based on a preset association relationship.

[0052] It should be noted that obtaining the preset interval character segment includes: obtaining a first random number, setting the number of bytes of the first preset interval character segment according to the first random number; obtaining a second random number, setting the number of bytes of the second preset interval character segment according to the second random number; obtaining a current timestamp character segment, and calculating the current bit value of each byte of the preset interval character segment according to the current timestamp character segment; where the current bit value of each byte of the preset interval character segment is the current bit value of each byte of the first preset interval character segment or the current bit value of each byte of the second preset interval character segment; generating a first preset interval character segment according to the number of bytes of the first preset interval character segment and the current bit value of each byte thereof; generating a second preset interval character segment according to the number of bytes of the second preset interval character segment and the current bit value of each byte thereof; and obtaining the preset interval character segment according to the first preset interval character segment and the second preset interval character segment.

[0053] Specifically, perform a unique relationship mapping between the generated preset interval field and at least one unframed data information character segment, so as to associate at least one unframed data information character segment with the preset interval character segment.

[0054] Step S05: Based on a preset second character window, perform box selection on the obtained at least one target data information string to obtain at least one target data information character segment selected by the box.

[0055] In specific implementation, the sliding rule of the second character window is that the sliding distance of the second character window is less than the length of the second character window.

[0056] It should be noted that by sliding the second character window with the sliding rule that the sliding distance of the second character window is less than the length of the second character window, the characters in a certain target data information character segment are partially repeated with the characters in the previous target data information character segment, so that the user can conveniently reorganize the split target data information character segments only according to the repeated characters in the subsequent process.

[0057] In a specific embodiment, as Figure 3 shown, a second character window with a length of 4 bytes is slid on a certain target data string to be processed, and the sliding distance each time is 3 bytes, so that the first character of the current target data string is repeated with the last character of the previous target data string.

[0058] Step S06: Store the at least one target data information character segment in a target memory.

[0059] In specific implementation, obtain the identifier of the at least one target data information character segment, and based on the identifier of the at least one target data information character segment, store the at least one target data information character segment in the target memory.

[0060] In summary, the method of the present application uses a first character window to perform box selection on a data information string exceeding a preset length to obtain a data information character segment selected by the box and a data information character segment not selected by the box, and replaces the data information character segment not selected by the box with a preset interval character segment, and splices the preset interval character segment and the data information character segment selected by the box to form a target data information string, realizing that even if an intruder performs forced decryption on each data information character segment, the required data information character segments cannot be spliced according to the semantics of each data information character segment, effectively improving the confidentiality effect of the data information string, and by using a second character window to perform box selection on the target data information string, the purpose of segmented storage of the target data information string is realized, and the problem of insecure data storage caused by segmented encryption of data information characters and then storage is solved.

[0066] A splicing module 14, configured to associate at least one unselected data information character segment with a preset interval character segment, and splice the preset interval character segment with the at least one selected data information character segment based on the positional relationship between the at least one selected data information character segment and the at least one unselected data information character segment, forming at least one target data information string;
