Robust Watermarking of Color Images under Noise and Cropping Attacks in Spatial Domain

Alankrita Aggarwal, Monika Singla
In this paper a novel spatial domain multiple watermarking scheme for color Images is proposed. The proposed scheme is of type blind and invisible watermarking. A binary watermark image is permutated using a secret key. The host image is divided into five blocks .Blocks size equals on the size of watermark image. The watermark is a binary image, embedded into five blocks of the host image by altering LSB values of the selected region.After performing OR operation on extracted watermarks, Only
