the 7 GB hard drive to a one base per square nanometer‚ it is 100‚000 times smaller.Clelland (1999) have demonstrated an steganography approach by hiding secret messages encoded as DNA strands among a multitude of random DNA. He used substitution cipher for encoding a plaintext where a unique base triplet is assigned to each letter t‚ each numeral and some special characters. One time cryptography with DNA strands is the practical implementation of DNA cryptography .It is quiet hectic because of
