独立且不言自明的DNA存储系统
A self-contained and self-explanatory DNA storage system
摘要：
目前DNA存储的研究主要集中在通过开发有效的编码和解码方案来提高存储密度，而缺乏对超长期数据存储和保留的不确定性的考虑。因此，目前的DNA存储系统往往不是独立的，这意味着它们必须求助于外部工具来恢复所存储的DNA数据。这可能会导致数据丢失的高风险，因为由于未来的高度不确定性，所需的工具可能无法使用。为了解决这个问题，我们在本文中提出了一个自包含的DNA存储系统，它可以在不依赖任何外部工具的情况下对其存储的数据进行自我解释。为此，我们设计了一个特定的DNA文件格式，从而开发了一个单独的存储方案，以减少数据冗余，而一个有效的索引是专为随机读取操作存储的数据文件。我们通过实验数据验证，所提出的自包含和自解释的方法不仅可以摆脱对外部工具的数据恢复的依赖，而且还可以最小化当要存储的数据量达到一定规模时所带来的数据冗余。
英文摘要：
Current research on DNA storage usually focuses on the improvement of storage density by developing effective encoding and decoding schemes while lacking the consideration on the uncertainty in ultra-long-term data storage and retention. Consequently, the current DNA storage systems are often not self-contained, implying that they have to resort to external tools for the restoration of the stored DNA data. This may result in high risks in data loss since the required tools might not be available due to the high uncertainty in far future. To address this issue, we propose in this paper a self-contained DNA storage system that can bring self-explanatory to its stored data without relying on any external tool. To this end, we design a specific DNA file format whereby a separate storage scheme is developed to reduce the data redundancy while an effective indexing is designed for random read operations to the stored data file. We verified through experimental data that the proposed self-contained and self-explanatory method can not only get rid of the reliance on external tools for data restoration but also minimise the data redundancy brought about when the amount of data to be stored reaches a certain scale.
