Hiding A Secret Watermark In Image Using Intelligent Water Drops Algorithm

Abstract

Information hiding is one of the great significance in our lives today. Especially when it is sent from one place to another place (from sender to receiver) so it is necessary to find an excellent way to hide this secret information. In this paper we will use the Intelligent Water Drops Algorithm (IWDA) to find the best locations in the cover image (color image) that will be used to hide secret watermarkimage, this algorithm is used to find the best solutions in the search space by depending on their behavior to reach the goal quickly and efficiently, the (IWD) is nature-inspired swarm-based optimization algorithm, it is depend on the processes that occur within natural river system to find the best paths among many paths and can get-away from local optima more readily than evolutionary algorithms. The PSNR value for new objective (stegoimage ) it has been measured, and it was very good, where the PSNR value for the image (1) and the image (2) were 82.74 and 81.71 respectively.
