A New Approach For Chaotic Encrypted Data Hiding In Color Image

Sending encrypted messages frequently will draw the attention of third parties, i.e. crackers and hackers, perhaps causing attempts and revealing the original messages. In digital world, Steganography is introduced to hide the existence of the communication by concealing encryption message inside color image. This paper proposed a steganography algorithm that hides encrypted text in color image by using chaotic hybrid approach. First, the text will be encrypted by one of substitution encrypted methods then, the result will be hidden in a color image by using the chaotic equation (which is also used to create cipher text). Then, measurements PSNR, MSE and NC are used to calculate the effectiveness of the proposed method is described pictorially and also has been shown that a multilevel of security of data can be achieved.
