(Rotate, salt and pepper, scale).

Measurements are shown in the Table III below.
Following the attacks, the image was rotated and checked
whether the original bits could be recovered once they
returned to their original shape. It was able to overcome this
assault. On the contrary, in scale attacks, there was no way
to extract the watermark because it was too fragile, and the
pixel values changed when zoomed in or out, affecting the
extraction process. In regards to the Salt and Pepper assault,
the watermark was successful, and the majority of the bits
were recovered.

Another attack involved the deletion of an image,
and a component from another image was copied and pasted
into the image where the watermark was embedded. As
indicated in the table, the suggested work successfully
detected this manipulation process. The effects were visible
in the logo through apparent distortion, which helped
determine the location of the alteration.
