Abstract: We are proposing a simple watermarking method
based on visual cryptography. The method is based on selection of
specific pixels from the original image instead of random selection of
pixels as per Hwang [1] paper. Verification information is generated
which will be used to verify the ownership of the image without the
need to embed the watermark pattern into the original digital data.
Experimental results show the proposed method can recover the
watermark pattern from the marked data even if some changes are
made to the original digital data.
