| Achoimre: | Today’s digital data storage systems typically offer advanced data recovery solutions to address the problem of
catastrophic data loss, such as software-based disk sector analysis or physical-level data retrieval methods for
conventional hard disk drives. However, DNA-based data storage currently relies solely on the inherent error
correction properties of the methods used to encode digital data into strands of DNA. Any error that cannot be
corrected utilizing the redundancy added by DNA encoding methods results in permanent data loss. To provide
data recovery for DNA storage systems, we present a method to automatically reconstruct corrupted or missing
data stored in DNA using fountain codes. Our method exploits the relationships between packets encoded with
fountain codes to identify and rectify corrupted or lost data. Furthermore, we present file type-specific and
content-based data recovery methods for three file types, illustrating how a fusion of fountain encoding-specific
redundancy and knowledge about the data can effectively recover information in a corrupted DNA storage
system, both in an automatic and in a guided manual manner. To demonstrate our approach, we introduce
DR4DNA, a software toolkit that contains all methods presented. We evaluate DR4DNA using both in-silico and
in-vitro experiments. |
