Data transmission, security and authenticity, nowadays is considered the major source of problems. To face these problems a suitable solution have to be forwarded . Steganography is forwarded  one of the solutions as a technique among many. This paper includes proposal for using a new technique called (Quick Respond Codes) QR Codes .
QR Codes technique is mainly used to convert and store messages since it has higher and large storage capacity, in addition to that we used, in this paper , the STR (Short Tandem Repeats) DNA sequence. STR DNA is very important because each person has its own DNA which means that security and authentication ) reliable ( are very high. The proposed  method   is to convert the hidden data (STR DNA sequence) to QR code that mean the security is at maximum. Then, by using the MD5 (Message Digest 5) Algorithm,  the result data is converted to QR code and the data within the data areas are stored in an unusually large format to make retrieval difficult.
Finally, STR DNA sequences were applied in different lengths and converted to QR code. By this method , the QR code is applied in different applications and it was very fast (3-4 second). To apply this technique and to reduce the cost, we use a webcam to get back the private (confidential) data from the QR code. The data were retrieved completely without any error because QR code is reliable and authentic. From the above result we suggest to use QR Code for indentification of  the of the individual (ID).

Researchers begin to explore new methods to manage the huge amount of data shared over the Internet, in order to use them more efficiently and safely, One of the ways that is raised nowadays is Steganography, The art of information hiding within electronic media. Steganography ways vary in their approaches for hiding information.
During this research designed algorithm that using restriction enzymes to cutting sequence of DNA, the fragments  resulted was used to building symbols table (character , number , special character,…),by using symbols table the plain message (text ,sound ,image ,video) coding to DNA and sent it to recipient, the recipient build symbols table same way in the sender site and use function to known restriction enzymes, using restriction enzymes to cutting  secret sequence DNA , by using the fragments of DNA and symbols table can  retrieve the plain message  (text ,sound ,image ,video).

Modern studies focused on Deoxyribonucleic acid (DNA)  because that DNA have several important features including the random nature of the sequence of nitrogenous bases consisting the acid and large storage capability of the information that led to it’s usage in the field of encryption where the appearance of a new branch which is encryption of DNA . This research provided a new method to encrypt text files using DNA were building a set of coding tables and using them to obtain the cipher text in DNA  form , also used a set of transposition cipher methods for the purpose of increasing the security of the resulted cipher text .

An Analytical Study of DNA Sequence

This paper contains a general introduction to Bioinformatics, theirs goals, objectives and their applied fields. Is then shed light on the real views of DNA of humans, some processors use mathematical and statistical analysis of the traditional purpose of these observations and to identify some features and characteristics. Graphical analysis of DNA is carried out in two and three dimensions. The inter-connectedness among the sites of DNA is also analyzed as well as a spectral analysis. The attempt is also made to identify the order of such observations. Through this analytical study it is shown that DNA has a complex structure with interdependent with each other for  long-term.
