METHODS FOR STORING AND READING DIGITAL DATA ON A SET OF DNA STRANDS

摘要

In one embodiment, it is proposed a method for storing input data on a set of DNA strands, said input data being represented in a numeral system. This method is remarkable in that it comprises: formatting said input data into a set of blocks of data, each block of data having a size inferior to a size of one DNA strand; applying a first encoding with an erasure code on said set of blocks of data, defining a first set of modified blocks of data, each modified block of data having a size inferior to a size of one DNA strand; applying a second encoding using an error correcting code on each modified block of data of said first set, defining a second set of modified blocks of data, each modified block having a size inferior to a size of one DNA strand; encoding each modified block of data of said second set into a nucleotides block sequence; generating a set of DNA strands, each DNA strand comprising a nucleotides block sequence obtained through said encoding.
