Whose image is this?

A Lunara Mark is an invisible mark written into an image by its owner, pointing at a public record: who registered it, when, and the fingerprint of the original. Choose an image to check it, or enter a mark id. The image is read on your device and never uploaded.

A mark survives re-saving and cropping, but not resizing, rotation or heavy filters. A missing mark does not mean an image is not someone’s. The mark proves nothing by itself; the record does. About Lunara Lens
