This article discusses how DNA might be used to store data. It is argued that, at present, DNA would be best employed as a long-term repository (thousands or millions of years). How data-containing DNA might be packaged and how the data might be encrypted, with particular attention to the encryption of written information, is also discussed. Various encryption issues are touched on, such as how data-containing DNA might be differentiated from genetic material, error detection, data compression and reading frame location. Finally, this article broaches the difficulty of constructing very large pieces of DNA in the laboratory and highlights some complications that might arise when attempting to transmit DNA-encrypted data to recipients who are a long period of time in the future.
本文讨论了DNA如何可用于存储数据。有人认为，目前DNA最适合用作长期储存库（数千或数百万年）。还讨论了含数据的DNA如何进行打包以及数据如何加密，尤其关注书面信息的加密。文中还涉及了各种加密问题，例如如何将含数据的DNA与遗传物质区分开来、错误检测、数据压缩和阅读框定位。最后，本文提到了在实验室构建非常大的DNA片段的困难，并强调了在试图将DNA加密数据传输给未来很长一段时间后的接收者时可能出现的一些复杂情况。
