Hiding a Secret Information in Image Using Gravitational Search Algorithm

Abstract

Information is so important thing to us. Therefore, protecting the data by using information concealing techniques have become interest in the most applications. This paper proposed new algorithm is gravitational search algorithm in order to determine best locations in a carrier image (color image) that will be used to conceal secret information by effective and efficient method, this paper propose an effective and efficient method for determining best hiding locations in a carrier (colored image) by using gravitational search algorithm. The gravitational search algorithm is depended on gravity rules that concerns the fact that an object with mass attracts one another. The PSNR of the stego image1 and stego image2 are 72.55 and 71.21 respectively.
