DNA information storage method based on Raptor codes and quaternary RS codes

Abstract

The invention discloses a DNA information storage method based on Raptor codes and quaternion RS codes. The method comprises a DNA information storage process based on Raptor codes. The DNA information storage process comprises the following steps: 1, converting an information file needing to be stored into a binary code stream; 2, encoding the binary code stream into a base sequence containing A,T, C and G by using Raptor codes; and 3, adding a quaternary RS error correction mechanism to the base sequences to ensure the correctness of information storage, then adding primer segments requiredfor synthesizing DNA to the two ends of the base sequences, and synthesizing the base sequences into DNA chains by using a biotechnology to complete information storage; compared with the prior art,the DNA storage technology realized by the invention has the beneficial effects of good ductility, high encoding and decoding efficiency, low complexity and the like.

Description

technical field [0001] The invention relates to the technical field of DNA information storage. Background technique [0002] In today's era of information explosion, the world has produced more information in the past two years than in the past five years. Digital information is growing and accumulating at an astonishing rate. It is estimated that by 2020, as many as 4.4×10 13 GB of information data. At this stage, the storage devices used by people, such as magnetic disks and semiconductors, are gradually exposed to inherent deficiencies, and it is urgent to find a new generation of alternative storage technologies. [0003] As early as the 1970s, foreign scholars proposed the idea of ​​using various states of DNA to represent information. But domestic research in this field is still in its infancy. [0004] Deoxyribose nucleic acid (Deoxyribonucleic Acid, DNA) is a kind of natural information carrier, which has inherent advantages such as large capacity, intensive stor...

AI Technical Summary

Problems solved by technology

Although DNA storage technology is still in the academic research stage due to factors such as high cost, time-consuming, and many technical difficulties, it has not yet been put into commercial application, but from the perspective of long-term investment, many manufacturers believe that it is very valuable, which is very important. May become a breakthrough in the future storage media market

[0005] At present, the coding and decoding technology used in the field of DNA information storage has disadvantages such as easy loss of information, poor scalability, low coding and decoding efficiency, and high complexity. In addition, most of the error correction mechanisms introduced are binary error correction, while DNA bases are quaternary sequence
