Every camera sensor has a unique fixed pattern noise, called Photo Response Non Uniformity (PRNU). Our new application Photoclean estimates PRNU and removes it from photos. This unique noise not only degrades the photo, but can also be used as a fingerprint to associate a photo with a camera. Once you remove it, you obtain a cleaner photo and eliminate the possibility of camera and photo association. Any feedback will be appreciated.

Interesting, seems like something every digital camera should have the ability to do by default.

Although, the privacy issues could be a larger concern in some instances. Such as a source to news paper ect... if not applied it could be used to identity photos taken by the same individual, which could then de-anonymize them.
