Safeguard your ownership by stamping a watermark on pictures.
Stamp Shhere handles solid marks or semi-transparent watermarks.

An absolute security in protecting ownership in photos and images does not exist.
Some primitive digital signatures can be defeated by removing all additional data from a photo, like Exif or IPTC data.
More complex protections hide their signature inside the pixel data, but they can also be defeated by applying filters, changing the format or making screenshots. There are also some hacker tools out to defeat those protections
Solid marks are often placed in one corner of a photo and can easily be cut out or retouched by cloning a similar zone.
Watermarks (semi-transparent mark) can be placed over the most important part of a photo and are nearly impossible to be retouched without traces. Another important advantage of watermarks are that other people immediately see your logo in stolen pictures. This protection is the most public visible one.
