Test Images for Invisible Watermarking. Various attacks performed on three Test Images. Stirmark Benchmark is used for testing the robustness of the Watermark.


Visible Watermark Embeding

1. Open the Image to be Watermarked in the tool Window.

2. Open the Visible Dialog Box.

3. Select the Watermark Image..

4. Select the position where the Watermark should be inserted. For this we have provided with 9 positions.

a. Top Left.

b . Top Center.

c . Top Right.

d . Middle Left.

e . Middle Center.

f . Middle Left.

g . Bottom Left.

h . Bottom Center.

i . Bottom Left.

5. Select the Intensity with which the watermark should be inserted.

Invisible Watermarking -- Embeding


1. Select the Host Image which is to be Watermarked.

Image_open_iem.JPG

2. Open the Invisible Embed Dialog Box.

3. Select the Watermark Image. The Watermark Image should be binary. It can be of any size (even larger than the original image).

4. Enter the Watermark Key. The key should be from 6 to 56 characters.

2. Select the Original Image.

3. Select the Watermark Image. (The same binary image used during embeding)

4. Enter the same Watermark Key which was used during embeding.

5.Click the Extract button.

a) If the Suspect Image received by the receiver and the the Watermarked Image send by the sender match, then the Owner is Authenticated.
