A file storage method, device, equipment and computer-readable storage medium

Abstract

The application discloses a file storage method, including: obtaining the file to be stored, and converting the file to be stored into a corresponding binary code string; dividing the binary code string according to the first digit, and dividing the divided code Strings are grouped according to the second digit to obtain the corresponding segmented code group; in the same segmented code string, use the preset balance sequence to replace the first segmented code group in the segmented code group, and use the second segmented code group Supplement the number of digits of the third segmentation code group to be equal to the number of digits of the balanced sequence; wherein, the contents of 0 and 1 in each balanced sequence are equal; determine the DNA information according to the corresponding relationship of each segmentation code group and the base mapping relationship Fragments, and store DNA information fragments. The method can increase the logical storage density of the DNA information fragments and improve the actual storage efficiency of the nucleotide storage space. The present application also discloses a file storage device, equipment and storage medium, all of which have the above beneficial effects.

Description

technical field [0001] The present invention relates to the field of information storage, in particular to a file storage method, device, equipment and computer-readable storage medium. Background technique [0002] In recent years, the rapid development of information technologies such as artificial intelligence, cloud computing, and the Internet of Things has triggered a rapid growth of data files. Although with the advancement of technology, storage hard drives are constantly being optimized and improved, but they are far from meeting the storage needs of explosively growing data information. The prior art proposes an information storage method based on a DNA storage medium, which reduces the storage space required for storing a file to be stored by performing DNA encoding on the file to be stored. However, in the prior art, it is necessary to introduce an error correction code into the DNA encoding process to control the content of guanine and cytosine in the DNA inform...

AI Technical Summary

Problems solved by technology

For example, originally 100 nucleotides can store 100 bits of information in the file to be stored, but setting the error correction code takes up 10 bits, that is, 10 nucleotides are needed to set the error correction code, so the actual storage of the file to be stored is only Can utilize 90 nucleotides

In this way, the logical storage density of DNA information fragments will be low, the nucleotide storage space that can be actually occupied by the file to be stored is small, and the actual storage efficiency of the nucleotide storage space is low
