Invisible Image Watermarking

In recent years, as an enormous number of digital photographs and images becomes publicly available, the necessity for an effective protection of the intellectual property rights of the content owners emerges. Image watermarking, which is the process of hiding digital information in images, is a concerted approach to address this need. The main challenge in image watermarking is the robustness of the watermarking techniques against several types of attacks that do not substantially degrade the image’s visual quality. The image watermarking scheme, developed by ITI, is a blind (no need for the original content during the watermarking detection) and almost imperceptible scheme, robust to the following attacks:

  • Noise addition
  • Cropping
  • Scaling
  • Rotation
  • Transcoding
  • JPEG compression
  • Smoothing and sharpeningons
