How does ImageTracker differ from the other ways to track images?
There are many ways to track images on the Internet. Some methods embed digital watermarks into the photo image by adding extra data to the image. Images can then be found by searching for the unique signature of the digital watermark. However, these watermarks can be altered or eliminated from the photo as the image is converted from one file type to another. A more reliable method is image recognition. This method examines raw image data to identify image “fingerprints” – unique patterns that are part of the image itself. This is the technique PicScout uses. Because this method does not rely on embedded watermarks surviving many forms of digital alterations, image recognition can match even highly manipulated or altered images with their original sources. PicScout proprietary image fingerprinting technology allows PicScout to identify images wherever they appear on the Internet, even if the image has been altered, colorized, edited, cropped, rotated or embedded into another image.
