Smart kids: The winners of the
Intel Science Talent Search:
Viviana studied steganography, a data encryption technique that embeds secret
messages within large amounts of seemingly innocent information. She
encrypted the message, "JUNE6_INVASION: NORMANDY," inserted it in the
gene sequence of a DNA-strand, and flanked it by two secret "primer" DNA
sequences. Then she combined the molecule with many other similar
molecules. The hidden message could be retrieved only by someone knowing
the two secret primer sequences - the keys to the code. Because the pair
of primers provides a trillion trillion options, she concludes that the
code is essentially unbreakable.
