Improving Encryption Digital Watermark by Using Blue Monkey Algorithm

Abstract

Watermarking enables the users to share the digital contents in public domain without any issue. In the present day, the tremendous development in the digital technologies and networks caused an increase in the threats of unauthorized copying, tampering of digital media and image theft. To face these threats, digital watermark technology can be applied. However, the current paper uses new technique with two main algorithms that are the following ones: improved honey algorithm that is used to encrypt the digital watermark and blue monkey meta-heuristic algorithm which is used to find the best location in the host image to hide the digital watermark. Furthermore, in order to check the security and the robustness of the proposed method against various common image processing attacks such as Gaussian noise, Rotation, Salt and pepper noise, Sharpen, Median filter, Average filter, compression and Cropping is computed, certain performance metrics such as Peak to Signal Noise Ratio (PSNR)and Mean Square Error (MSE) also are computed. Likewise, Normalized Correlation (NC) is used to check similarity between the original and extracted digital watermark. The results demonstrate that the proposed method is efficient, provides high security and robustness against most attacks compared to the pervious methods.

Compression Run Length Encoding On Watermarking Using a Combination of DCT, DWT and SVD

“…Identification of medical images will be easier to find out the true owner of medical image data efficiently. One solution approach for identifying medical image data is watermarking, the definition of watermarking is a technique of hiding data into multimedia content such as images, video or audio where watermarked images can be extracted [4], [5]. In other studies digital watermarking is used to improve medical image security, confidentiality and integrity.…”
