Use of Digimarc
Each image is imbedded with a unique digital watermark from Digimarc. Imperceptible to the eye, Digimarc covert watermarks allow the image to be tracked across the web. The digital watermark persists through file copying, format changes, encryption and decryption, and image manipulations such as editing, cropping, compression and decompression.
The use of Digimarc allows us to manage unauthorized use of images and to know that images are used at the right time and in the right context

We are also starting to use a new product that uses image identification technology rather than keywords, metadata or watermarks. This product finds exact and altered copies of the images that you submit, including those that have been cropped, colour adjusted, resized, heavily edited or slightly rotated.
