What are you asking, how to watermark an image in Aperture, what the watermark should say, something else?
A watermark is a watermark. Once it is on an image it is pert of the image. There are no more secure ways to place a watermark on an image.

Depending on what specifically you are trying to accomplish with the watermark, you may want to check out Digimarc, a subscription service that embeds code in your photography in a way that communicates copyright information and allows you to track your images across the web.
Downside: it's a subscription service
