With the advent of the Internet, you can compose digital media by distributing their works by making them available on web pages or public discussion forums. A person who has the authority to access pages or forums can copy and modify these media and obtain a copy that is completely identical to the original. The use of digital media for multiple problems including how authors can guarantee the property rights of their works. The multimedia was included with additional information to protect the media before it was distributed.
In this paper, a new method has been proposed to include the watermark in images of any kind. An improved algorithm has been proposed which breaks the data of the watermark (Datas) into blocks (Blokes) with the technique of cutting the map. Then the LSB (Least Bit Bit) algorithm was applied for masking. For better results, the whale algorithm was used to determine the optimal placement of concealment.
The effectiveness of the algorithm comes from obtaining the optimum value of peak signal-to-noise (PSNR) (peak-to-noise ratio), thereby determining the best location for concealment, as well as the value of the mean square error MSE (mean square error). And compare the results between the LSB algorithm by standard methods and our stated algorithm.
The results obtained are indicative of the efficiency and robustness of the algorithm, as it is characterized by its durability due to its resistance to many attacks carried out on the image.
It was adopted on the Visual Studio 2016 environment because it contains highly efficient functions dealing with the proposed algorithm
