a.k.a. Biostorage or Biocryptography
It is the science of systematically storing data
into an organism with the capability toretrieve it in the future
It has been around for about a decade

In 2007, Japanese students from
Keio University, led by Dr. Nozomu
Yachie, has successfully wrote
the infamous e=mc2 formula in a
bacterium
They were able to store data but
failed in retrieving it.
