  Description     : resilient invisible digital watermarking tool for images
Imagewmark embeds and extracts encrypted, invisible digital watermarks
in image files.
.
Using a key-based cryptographic scheme, the embedded watermark can be
reconstructed from cropped, scaled, or compressed variants of the
watermarked
image without requiring access to the original source image (blind
decoding).
.
The watermark embedding and detection algorithms are resilient against local
geometric distortions and lossy compression formats.

- why is this package useful/relevant? is it a dependency for
   another package? do you use it? if there are other packages
   providing similar functionality, how does it compare?

I use it to embed some watermark into the image. Especially with my
own signature or an ID copy.

- how do you plan to maintain it? inside a packaging team
   (check list at https://wiki.debian.org/Teams)? are you
   looking for co-maintainers? do you need a sponsor?

I don't need a sponsor.
