Technical Field

Background technique

As the demand for data storage continues to increase, modern data storage systems are overwhelmed by high infrastructure costs and operating power consumption, and a durable, scalable and economical alternative storage medium is urgently needed. As a carrier of genetic information, DNA itself is a natural and excellent storage medium that not only stores the genetic information of billions of lives from microorganisms to humans, but also ensures the stable inheritance of life phenomena. DNA storage technology is a new field that integrates DNA synthesis and sequencing technology with computer storage. It converts the 0 and 1 binary data in the computer into a DNA sequence composed of four bases, A, T, C, and G, through a coding algorithm, and then realizes the storage of data information by synthesizing DNA containing a specified base sequence.

However, the existing DNA data storage technology is single-minded, only converting files into binary strings for encoding. Once part of the sequence is lost during decoding, it will lead to catastrophic error propagation, and it cannot be adapted to special storage application scenarios. In addition, there are few mechanisms for block reading in the existing technology, and only the entire sequence can be decoded when decoding data, which is time-consuming and has low storage efficiency.

Detailed ways

The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be interpreted as limiting the present application.

It will be understood by those skilled in the art that, unless expressly stated, the singular forms "a", "an", "said" and "the" used herein may also include plural forms. It should be further understood that the term "comprising" used in the specification of the present application refers to the presence of the features, integers, steps, operations, elements and/or components, but does not exclude the presence or addition of one or more other features, integers, steps, operations, elements, components and/or groups thereof.

In addition, the "connection" or "coupling" used herein may include wireless connection or wireless coupling. The term "and/or" used herein includes all or any unit and all combinations of one or more associated listed items.

As mentioned above, due to the increasing demand for data storage, there is an urgent need for a durable, scalable and economical alternative storage medium. As a carrier of genetic information, DNA itself is a natural and excellent storage medium. The method of storing data through DNA has the advantages of high storage density, long shelf life, low maintenance cost and easy data backup.

There are two main methods for the most common image DNA encoding and decoding: 1. Direct file encoding and decoding. This method does not need to consider the format of the image file. It directly converts the file into a binary string, segments it, and encodes it into a base sequence. Decoding is the inverse process. 2. Frequency coefficient encoding and decoding. This method is limited to image files in JPEG format. According to the error sensitivity of the frequency coefficients in JPEG, the DC/AC frequency coefficients are encoded into different DNA sequences for storage, and appropriate internal indexes are designed to associate these coefficients with their corresponding images, which has better fault tolerance during decoding.

However, the above-mentioned image DNA encoding and decoding method also has shortcomings, including: 1. The encoding method is relatively simple, and the file is only converted into a binary string for encoding. Once part of the sequence is lost during decoding, it will lead to catastrophic error propagation, and it cannot be adapted to special storage application scenarios. For example, if you only need to look at a certain position of the image, the existing technology can only decode the entire sequence, which is time-consuming; 2. The image format that can be encoded is limited, and in order to pursue high-quality sequences, most of them introduce complex sequence screening mechanisms, which takes a long time to encode and has low encoding efficiency.

It can be seen that the related technology still has the problem of single storage method and low efficiency.

To this end, the image data DNA storage method provided by the present application realizes the block reading of image data, pursues low-cost reading while efficiently encoding, shortens the encoding and decoding time, and improves the encoding and decoding efficiency.

In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

FIG1 is a method for storing image data in DNA, which may include the following steps:

Step 310: obtain an image to be encoded, and split the obtained image into several image blocks.

The image to be encoded is an image that needs to be stored through DNA data storage technology.

In a possible implementation, after obtaining the image to be encoded, in order to divide the image as equally as possible, the width and height pixel values of the image are obtained, and the two pixel values are divided by the number of blocks to be equally divided, and the two pixel values are rounded down to obtain a number of equally divided first image blocks. The number of blocks to be equally divided can be customized according to the actual application scenario and is not specifically described here.

Step 320: performing binary conversion on the obtained image blocks to obtain corresponding binary data strings.

For all the obtained image blocks, according to the pixel values corresponding to the respective pixel points in the image, the pixel values in the decimal representation are converted into binary data strings through binary.

Step 330, using a quaternary bit-base mapping rule to perform base conversion on the binary data string to obtain a corresponding first base sequence; the quaternary bit-base mapping rule includes a plurality of quaternary bit-base mapping tables.

In a possible implementation, the present application provides a new bit-base conversion rule, a quaternary bit-base mapping rule, which converts a binary data string into a DNA sequence containing four bases, A, T, C, and G, according to a specific mapping rule.

Step 340: Number the first base sequence using the numbers converted according to the specific base conversion rule to obtain a second base sequence including a block number; the block number is located at the head of the second base sequence.

A numbering sequence for numbering is obtained, where the block number is obtained by converting the original decimal number into binary and performing base conversion according to the rules of 00-A, 01-T, 10-C, and 11-G, thereby adding the block number after base conversion to the head of the second base sequence for numbering.

Step 350, adding a new primer to the second base sequence and performing DNA synthesis to obtain DNA storage data.

In a possible implementation, as shown in FIG2 , the above step 330 includes the following steps:

Step 331, use the quaternary bit-base mapping table A* to perform base conversion on the first 4 bits of the binary data string to obtain two initial bases.

Step 332: If the two initial bases are in overlapping form, the subsequent 1 or 2 bits are first converted into bases using the quaternary bit-base mapping table A to obtain the third base.

Step 333, based on the two initial bases being in overlapping form, if an overlapping form is encountered next time, the quaternary bit-base mapping table B is used to perform base conversion; otherwise, the quaternary bit-base mapping table B* is used to perform base conversion.

Step 334, if the last overlapping form uses the quaternary bit-base mapping table B for base conversion, the next overlapping form uses the quaternary bit-base mapping table A for base conversion; the non-overlapping form uses the quaternary bit-base mapping table A* for base conversion.

Step 335: If the two initial bases are in a non-overlapping form, the subsequent 1 or 2 bits continue to use the quaternary bit-base mapping table A* to perform base conversion to obtain the third base.

In an exemplary embodiment, as shown in Table 1, the present application provides a new bit-base mapping rule - a quaternary bit-base mapping rule.

Specifically, for example, a string of binary data 0010 1101, the first 4 bits 0010 of the binary data string are base converted using the quaternary bit-base mapping table A*, and the two initial bases are AC. For the two non-overlapping initial bases, the subsequent two bits 11 are base converted to G using the quaternary bit-base mapping table A*. At the same time, for the subsequent bits that need to be base converted, the new two bases are CG. Based on the fact that the new two bases are in a non-overlapping form, the last bit 01 is base converted to T using the quaternary bit-base mapping table A*, that is, for the binary data string 0010 1101, the base conversion is ACGT.

For another example, a binary data string 0000 1101, first use the quaternary bit-base mapping table A* to perform base conversion on the first 4 bits 0000 of the binary data string, and obtain two initial bases of AA. For the two initial bases in overlapping form, the subsequent two bits 11 use the quaternary bit-base mapping table A to perform base conversion to G. At the same time, for the bits that need to be converted later, the new two bases are AG. At the same time, the quaternary bit-base mapping table B is used for base conversion when the overlapping form is encountered next time, and the quaternary bit-base mapping table B* is used for base conversion in non-overlapping form. Based on the new two bases being in non-overlapping form, the last bit 01 is converted to C using the quaternary bit-base mapping table B*, that is, for the binary data string 0000 1101, the base conversion is AAGC.

In an exemplary embodiment, as shown in Table 2, the quaternary bit-base mapping rule further includes a terminal bit processing table.

When the last 1 or 2 bits of the binary data string are left for base conversion, the end bit processing table is used to perform base conversion.

Specifically, in the case of a fixed binary string length, there may be a problem that there are 1 or 2 bits left at the end and no mapping rules can be found. In this case, base conversion is performed on them according to the end bit processing table. For the last 1 or 2 bits, different bases are selected for correspondence based on the form of the two closest bases. For example, when the first two bases are AA, if the last bit is 0, the corresponding base is TC; if the last bit is 1, the corresponding base is TG, thereby achieving base conversion for the last 1 or 2 bits.

Table 1 Quaternary bit-base mapping table

Table 2 Terminal bit mapping table

In a possible implementation, as shown in FIG3 , the image data DNA storage method provided by the present application further includes the following steps:

Step 410, transform the quaternary bit-base mapping table A and table B to obtain several new mapping rules.

Step 430: Encode the obtained several new mapping rules using the above encoding process, and record the GC content and encoding density in the result sequence after base conversion.

Step 450 , selecting the mapping rule corresponding to the result sequence with a GC content of 40%-60% and the highest coding density as output.

Specifically, the two columns TT in the quaternary bit-base mapping table A and table B are changed, and there are four different transformation forms for each of the two tables, thereby obtaining sixteen new mapping rules. The sixteen new mapping rules are encoded using the encoding process provided by the present application, and the GC content and encoding density in the result sequence are recorded at the same time. The corresponding mapping rule with a GC content of 40%-60% and the highest encoding density in the final result sequence is used as the most preferred bit-base mapping rule to implement data encoding.

In a possible implementation, as shown in FIG4 , after step 350 of the present application, the following steps are further included:

Step 360, sequencing the obtained DNA storage data to obtain base sequence data, and filtering the data required for block decoding according to the head base sequence in the obtained base sequence data.

In an exemplary embodiment, for a string of base sequences, the corresponding block number is determined according to its head base sequence, and the base sequence to be decoded is selected according to the block number. Then, the inverse process of the above encoding process is used to decode the base sequence to obtain the corresponding image data, thereby realizing a complete encoding and decoding process.
