Abstract: Intellectual property protection of digital images and multimedia is a prickly and largely unsolved problem. A highly robust biometric, dual watermarking technique using hand vein feature is proposed in this paper for securing digital images. In visible watermarking, the hand vein feature of an individual is embedded to the host image using Discrete Cosine Transform (DCT) in spatial domain. The invisible watermark is then EX-ORed with the bit planes of visible watermarked image. The hand vein biometric characteristic has been used to measure the identity of the recipient. This dual watermarking technique establishes owner|s right to the image.

Keywords: biometric watermarking; visible watermarks; invisible watermarks; hand vein biometrics; digital images; image security; dual watermarking; hand veins; vein patterns; intellectual property rights; IPR; IP protection; multimedia.
