A Hybrid of Steganography and Cryptography for Decreasing Mean Square Error and Bit Error Rate
Journal Title: International Journal of engineering Research and Applications - Year 2017, Vol 7, Issue 11
Abstract
Internet, being the common platform for information sharing among people has increased its importance in digital world. To keep this online sharing unrevealed or to save it from being stolen, some security measures are developed such as Watermarking, Cryptography and Steganography. Watermarking is the visible marking for copyright protection; Cryptography is to encrypt the data to make it difficult to understand whereas Steganography is covert writing for obscuring the information. Various features such as invisibility, payload capacity, robustness and imperceptibility make steganographic mechanism different and useful in comparison to watermarking and cryptography. There are some legitimate as well as illegitimate applications of steganography. When keeping security in point of view in order to protect the data, steganography is often more advantageous and its illegitimate uses can be overcome by legitimate ones. This paper gives an overview of steganography domains and their suitable field of application. In this paper, steganography and cryptography are combined to form a hybrid so as to attain low MSE as well as low BER by the use of space domain. The entropy achieved is 7.69.
