Hiding color images in DNA sequences

With recent advances in genetic engineering it has become possible to embed artificial DNA strands into the living cells of organ-isms. With DNA having a great capability for data storage, many methods have been developed to insert artificial information into a DNA sequence. However, most of these methods focus on the encoding of text data and little research has been done regarding the encoding of other media. Few methods have been researched to encode images and most of those are only for black-and-white images. We are proposing an algorithm to insert and extract color images in the form of bitmap files into a DNA sequence in the form of a FASTA file. Results from our experiments show that the proposed method is significantly more efficient than previous approaches.
