Abstract : Privacy is one of the most important issues in today's communication systems. In applications where the importance of your privacy is indispensable, the main aim is to send the information to desired target without being captured by the third persons or by bringing them in such a way that they cannot understand. Today, researchers have developed data hiding methods using a wide variety of digital media. At this point, it is important not only to hide data, but also to develop mechanisms to prevent third parties from identifying hidden data. In this study, a new method that combine chaos-based logistic map encryption with improved Least Significant Bit (LSB) insertion method of image steganography was proposed. The message to hidden is encrypted by one dimensional logistic map and then improved LSB method was used to form stego-image. Proposed method has been tested on 3 different images. Likewise, the classical LSB methods have also been tested on the same images. It has been seen that proposed method increased the resistance of stego-images against attacks due to encryption. Additionally, Peak Signal to Noise Ratio (PSNR) in the stego-images were increased up to 6.6% that means to decrease sense by the human observation. Thus, proposed method increased the resistance and visibility of the stego-images. Keywords - Encryption, Image Steganography, LSB, Logistic Map, PSNR.
