1. A steganographic method for creation of a secret code comprising:
- (a) producing a DNA molecule comprising a secret message DNA sequence that can be decoded with the use of an encryption key, flanked on each side by a primer sequence; and
(b) concealing the DNA molecule in a mixture of concealing DNA.

Abstract
The present invention relates to a stenographic method for concealing coded messages in DNA. The method of the invention comprises concealing a DNA encoded message within a genomic DNA sample followed by further concealment of the DNA sample to a microdot. The present invention further provides a method for the use of genomic steganography to mark and authenticate objects of interest.

7. A method of authenticating an object of interest comprising:
-
(a) adding at least one secret DNA molecule comprising a secret message DNA sequence flanked on each side by primer sequences to a mixture of concealing DNA;
(b) attaching the mixture of secret DNA and concealing DNA to the object to be authenticated or a tag affixed thereto; and
(c) detecting of the secret DNA;
wherein detecting of the secret DNA authenticates the object of interest. - View Dependent Claims (8, 9, 10)

11. A method of authenticating an object of interest comprising:
-
(a) constructing a two dimensional array of DNA dots containing concealing DNA;
(b) adding at least one secret DNA molecule to a subset of the DNA dots to form a pattern; and
(c) detecting of the pattern of dots that contain secret DNA sequence as a means for authenticating the object of interest. - View Dependent Claims (12, 13, 14)
