Which of the following tools is used to attack the Digital Watermarking?

  • Steg-Only Attack
  • Active Attacks
  • 2Mosaic
  • Gifshuffle

Explanation: 
2Mosaic is a tool used for watermark breaking. It is an attack against a digital watermarking system. In this type of attack, an image is chopped into small pieces and then placed together. When this image is embedded into a web page, the web browser renders the small pieces into one image. This image looks like a real image with no watermark in it. This attack is successful, as it is impossible to read watermark in very small pieces. Answer: D is incorrect. Gifshuffle is used to hide message or information inside GIF images. It is done by shuffling the colormap. This tool also provides compression and encryption. Answer: B and A are incorrect. Active Attacks and Steg-Only Attacks are used to attack Steganography.
