Abstract :
In this Paper, we present a new imperceptible digital watermarking system for images. This system is used for copyright protection, and is compared with base watermarking method (BWM) proposed by Koch et. al. The developed system is called ¿Digital Image Copyright Protector¿ (DIGICOP). It automatically generates the content owner´s unique Identification Mark from a supplied text string and a secret key. DCT is used as the embedding domain to achieve high resilience against image processing attacks, such as compression using JPEG, Gaussian Noise, Blurring, Color Inversion, Scaling and Cropping.
