This paper focuses on the digital image authentication and forgery localization using
demosaicing artifacts. The aim is to build an algorithm allowing a bridge between the color …

Existence of mobile devices with high performance cameras and powerful image processing
applications eases the alteration of digital images for malicious purposes. This work …

Almost all image sensors measure only one color per pixel through the color filter array.
Missing pixels are estimated using a demosaicing process. For this reason, a demosaiced …

Multimedia information typically requires large storage capacity and transmission rate. Thus,
multimedia data, which exist in various forms, such as images, audios, videos, and graphics …

The color filter array of the camera is an effective fingerprint for digital forensics. Most
