The technique involved placing data (in this case, The Declaration of Independence) in the DNA of bacterial cells, and can even harness site specific genetic recombination to encrypt the data. That said, the technology is still in its infancy: retrieving the info is "tedious and expensive," according to Cambridge University's Tim Middleton, and there is still the possibility that as organisms mutate, so will the data.
