Savvy criminals can use the same tricks as the police: if they can discover where and when a photo was taken, it can leave you vulnerable to crimes such as burglary or stalking.

In the digital image forensics community, this sensor fingerprint is known as "Photo response non-uniformity".

It's inherent to the sensor, as opposed to measures, such as photo metadata, that are "Intentionally implemented", she explains.

In principle, photos constitute a rich reference to the physical world, and can therefore be used for their evidential value, since they portray what is.

Fridrich has patented the photo fingerprinting technique, and it ==>has been officially approved for use as forensic evidence in court cases in the United States.

In light of what we now know about forensic photo tracking, such self-determination may only be an illusion of control.
