Abstract:

 Image authentication is a tedious process researchers have been established for new technical solutions for image authentication, in recent times started expansion of new methods aiming at blind passive detection of image splicing. Conversely, many other research societiesdealing with data processing need tocollect an open data set with various content and realistic splicing conditions in order to expedite the progresses and facilitate collaborative studies. A skilledimage editor can be done an image splicing process by verification of image authentication has become important. In this paper, we suggest a detection method for splicing boundaries that uses consistency on camera response function (CRF) in an image. The uniformity of CRF is detected as differential features. In some images, the non-uniformity of CRF typically appears on the edges of a splicing region. The physical appearance of CRF taken out from edges in an image differsamong a transformed region and an authentic region. The QR map is used to analyze the topographies that represent the relation between this features and image intensity. In common the CRF has an authentic boundary within an image, but a splicing boundary is not available.

Keywords:

Image authentication, CRF, image splicing boundary, QR map.
