Digital watermarking is a digital data that can be embedded in digital documents, images, audio and video. This watermark technique uses the unique biometric data of individuals. The individuals biometric of eye, vein and fingerprint is embedded in the digital image. These unique data are fused and encrypted. The fusion of three biometric data is output as a digital image. The host image is processed for embedding the fusion image in it. The process of embedding image in another image is watermarking. It is also the domain of image processing. Generally it means hiding an image in the host image. It is a technique to secure the unique data of owner in an image to prove the ownership of the owner. Watermarking the unique features in a digital image establish that the digital image is belongs to the user whose biometric data watermarked. The watermarking process is robust and perceptual transparency. The unique biometric data will logically prove the ownership of digital media.
