Claim One:
1. A process to assess integrity in a digital image comprising: estimating a camera response function (CRF) associated with the digital image; comparing the estimated CRF to a set of rules; comparing the estimated CRF to a known CRF, the known CRF associated with a make and a model of an image sensing device; receiving metadata stored in a header of the digital image, the metadata stored in the header of the digital image identifying a make and a model of an image sensing device that created the digital image; receiving metadata stored in a database, the metadata stored in the database associated with the make and model of the image sensing device that created the digital image; comparing the metadata stored in the header of the digital image to the metadata stored in the database that is associated with the make and model of the image sensing device that created the digital image; applying a fusion analysis to results obtained from comparing the estimated CRF to a set of rules, from comparing the estimated CRF to the known CRF, and from comparing the metadata stored in the header of the digital image to the metadata stored in the database that is associated with the make and model of the image sensing device that created the digital image; and assessing the integrity of the image as a function of the fusion analysis.
