Canon has developed a surefire method of countering photo thieves, it's managed to put in an iris scanner in its camera to generate Meta data and integrate it into the photos the user takes. Many photographers go to great lengths to protect their images. Past attempted solutions include watermarks on the front of images. More recently, in the digital age of photography, watermarking in Photoshop or other image editing software is a popular solution. While visible watermarks are common among a variety of photographers, invisible watermarks ("electronic or digital watermarks"), which are embedded in the image file, are somewhat less prevalent - but gaining ground and acceptance among photographers. Companies like Digimarc are pressing the digital watermark cause to protect photographer's and other author's data. After a recent story of photographer who discovered her own photos along with some that were her property on sale at iStockphoto.com, the need for such a secure form of digital protection is vital.

Additional embedded info can be added later. All metadata will be added to images after you're finished shooting in a collective manner and not for each image. The purpose of the collective tagging, if you will, is to refrain from hampering the camera's speed (frames per second) while shooting.
