METHOD FOR IDENTIFICATION OF DIGITAL VIDEO RECORDING EQUIPMENT
AND DIGITAL CAMERAS
Abstract. A method for constructing expert tools for forensic identification of digital video recording equipment and digital cameras is considered. The necessity of creating such tools is substantiated. It is proposed to carry out the identification of this equipment by the statistical characteristics of its own noise, extracted from digital images recorded by such equipment. The features and main sources of such noise in digital images are shown. For its selection and processing, wavelet analysis based on the Haar wavelet is used. The final result of the examination is obtained by applying deep learning neural networks. The obtained results of the created identification system for such equipment showed its high efficiency.
Keywords: digital video recording equipment, digital photography equipment, wavelet analysis, Haar wavelet, forensic identification, deep learning neural networks, intrinsic noise, digital images, forensics.
