Chaotic Map Based Random Image Steganography Using LSB Technique

Steganography play an important role to transfer secret data over insecure network. Moreover digital images are taken as a cover to communicate the sensitive data. One of the simplest approach of embedding the secret data into cover image is Least Significant Bit (LSB) method. This paper aims to propose a new symmetric key based image hiding technique. Pseudo random keys are generated by using 1D logistic map and those keys are used for choosing the pixel position of cover image randomly for hiding the secret image. The main security part of the projected method is the selection of pixel position in the cover image. Peak Signal Noise Ratio (PSNR) and Mean Square Error (MSE) measures are used for comparison and the result analysis shows that the proposed scheme provide efficient level of security.
