Abstract: DNA, as a highly dense and durable information storage medium, holds significant potential for the long-term preservation of cultural heritage data. This paper explores the process of converting data from the Dunhuang murals into DNA sequences using DNA storage technology, highlighting the application of dual-layer error correction codes and de Bruijn graph algorithms to ensure data stability and recoverability. Furthermore, the use of “cell disk” as a storage medium is expected to enable high-density and long-term DNA data storage. The goal is to inspire readers to engage with and explore cutting-edge technologies.

Key words: DNA storage, Mural protection, Prospects and challenges
