Abstract
Information hiding is very important during the transmission, so that it cannot be disclosed to unauthenticated persons. Steganography is one of the famous methods to hide the potential information. Many methods have been proposed by researchers to make a secure stegoimage. However, most existing methods suffer from low payload, distorted cover image, and poor security. To overcome these issues, in this chapter, we propose a steganography method based on differential evolution and the least significant substitution (LSB) method. Differential evolution is utilized to optimize the mask assignment list of LSB method. The mask assignment list is considered as the solution of a differential evolution. Thereafter differential evolution updates the solutions and provides the optimized assignment list for embedding a secret image into a cover image. The experimental results show that the proposed method provides better stegoimage quality and robustness against noise attacks as compared to other steganography methods.
