  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.
