A Novel Approach towards Development of Hybrid Image Steganography using DNA Sequences


Objective: For the purpose of Data Communication Steganography is a technique which is combination of both the science and art by which we may hide information inside other covered media. Method: Here we use 3-layers steganographic data encryption, in the first stage data are encoded based upon DNA-Sequence and then the stego-key is added with individual byte then the byte streams are encoded within the image. First encrypt the data is more secure than encoding the raw data and authentication values which provide access only to authorized persons. Finding: Only Steganography is not enough secure for the present scenario. Simple Steganography is very much vulnerable in front of attack, but if we apply some encryption on the data itself and then use Steganography then that will be more secure than the use raw data in Steganography. Application: It will cover all the fields where we need Data Security and it covers a zone of data security where we need to hide the existence of data.
