  As long as human beings exist on this earth, there will be confidential
images intended for limited audience. These images have to be transmitted in
such a way that no unauthorized person gets knowledge of them. DNA sequences
play a vital role in modern cryptography and DNA sequence based cryptography
renders a helping hand for transmission of such confidential images over a
public insecure channel as the intended recipient alone can decipher them. This
paper outlines an integrated encryption scheme based on DNA sequences and
scrambling according to magic square of doubly even order pattern. Since there
is negligible correlation between the original and encrypted image this method
is robust against any type of crypt attack.
