  The recent progress in DNA sequencing will probably revolutionize the world
of electronic. Hence, we went from DNA sequencing that only research centers
could realize, to portable, tiny and inexpensive tools. So, it is likely that
in a few years these DNA sequencers will be included in our smartphones.
  The purpose of this paper is to support this revolution, by using the DNA
cryptography, hash functions and social networks. The first application will
introduce a mutual entity authentication protocol in order to help waifs,
refugees, and victims of human trafficking to find their biological parents
online.
  The second application will also use the DNA cryptography and the social
networks to protect whistleblowers' actions. For example, this method will
allow whistleblowers to securely broadcast on social networks, their
information with one grape.
