Estimating the term…
Apparatus and method to verify the integrity of a digital image (i.e., deciding whether or not the entire image or just a portion has been tampered with, and/or finding the doctored area in the image). One first determines the imaging sensor's reference pattern noise, which serves as a unique fingerprint that identifies the imaging sensor that captured the image. To verify the integrity of the content in a region of the image, a correlation detector determines the presence or absence of the imaging sensor's reference pattern noise in that region, thereby verifying whether or not the image has integrity. The correlation detector can also find automatically one or more regions in the image that were tampered with. In another embodiment, one determines the pattern noise of only the image in question and tests that noise to determine whether or not the image has integrity.
A method for determining whether or not at least one digital image, obtained by a particular digital imaging sensor, has been tampered with, said method comprising the steps of:
An apparatus for determining whether or not at least one digital image, obtained by a particular digital imaging sensor, has been tampered with, comprising:
