脱氧核糖核酸（DNA）作为一种高密度、长时间保存的存储介质，可以满足档案数字量迅速增长的存储需求。DNA存储的读写过程是容易出错的。社交媒体中广泛使用的图像具有容错特性，非常适合DNA存储。然而，先前的工作仅仅调查了DNA存储器存储不同类型的数据的可行性，并且仅仅将图像存储在DNA存储器中，其没有充分调查图像在DNA存储器中的容错潜力。在本文中，我们提出了一个新的基于图像的DNA系统称为IMG-DNA，它可以有效地存储图像的DNA存储与提高DNA存储鲁棒性。首先，提出了一种新的DNA结构，以适应基于JPEG的图像，并提高图像的DNA存储的鲁棒性。此外，插入DNA序列中的屏障有效地防止了DNA存储图像中的错误传播。实验结果表明，所提出的IMG-DNA实现了更高的容错性比以前的工作。
Deoxyribonucleic Acid (DNA) as a storage medium with high density and long-term preservation properties can satisfy the requirement of archival storage for rapidly increased digital volume. The read and write processes of DNA storage are error-prone. Images widely used in social media have the properties of fault tolerance which are well fitted to the DNA storage. However, prior work simply investigated the feasibility of DNA storage storing different types of data and simply store images in DNA storage, which did not fully investigate the fault-tolerant potential of images in the DNA storage. In this paper, we proposed a new image-based DNA system called IMG-DNA, which can efficiently store images in DNA storage with improved DNA storage robustness. First, a new DNA architecture is proposed to fit JPEG-based images and improve the image's robustness in DNA storage. Moreover, barriers inserted in DNA sequences efficiently prevent error propagation in images of DNA storage. The experimental results indicate that the proposed IMG-DNA achieves much higher fault-tolerant than prior work.
