The Photo Response Non-Uniformity pattern (PRNU-pattern) can be used to identify the source of images or to indicate whether images have been made with the same camera. This pattern is also recognized as the “fingerprint” of a camera since it is a highly characteristic feature. However, this pattern, identically to a real fingerprint, is sensitive to many different influences, e.g., the influence of camera settings. The Photo Response Noise Uniformity is a unique pattern which can be used for identification of source device from captured data like images or videos. As identification of video acquisition devices is one of the considerable problems faced in multimedia forensics, so this paper presents work related to source device identification using PRNU fingerprint .The proposed method aims to classify videos to the respective source devices using simple statistic based algorithm. Extraction of PRNU is performed using denoising filters.
