File storage method, device and equipment and computer readable storage medium

Abstract

The invention discloses a file storage method, which comprises the steps of obtaining a to-be-stored file, and converting the to-be-stored file into a corresponding binary code string; segmenting thebinary code string according to a first digit, and grouping segmented code strings obtained by segmentation according to a second digit to obtain a corresponding segmented code group; in the same segmentation code string, correspondingly replacing the first segmentation code group in the segmentation code group by using a preset balance sequence, and supplementing the digit of the third segmentation code group to be equal to the digit of the balance sequence by using the second segmentation code group; wherein the contents of 0 and 1 in each balance sequence are equal; and determining a DNA information fragment according to the corresponding relationship of each segmentation code group and the base mapping relationship, and storing the DNA information fragment. According to the method, thelogic storage density of DNA information fragments can be improved, and the actual storage efficiency of nucleotide storage space is improved. The invention further discloses a file storage device and equipment and a storage medium which all 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
