Survey on Source Camera Identification Using SPN with PRNU

Retrieving photos from massive collections consistent with a particular criterion is an increasingly relevant task. A vital, however so far overlooked, such criterion is that the retrieval of images acquired by a selected camera.   Content primarily based image retrieval may be an ancient approach for retrieving pictures. The most vital   task is that the retrieval of images matching specific criterion. An important however to this purpose unmarked, such criterion is that the retrieval of pictures captured by a selected camera device. Photo Response Non-Uniformity (PRNU) of the camera sensor is utilized to retrieve image taken by specific camera. device  imperfections  in the shape of photo response  non-uniformity (PRNU)  patterns area unit  a  well-established process  technique  to  link footage to  the  camera  sensors  that nonheritable  them.   As PRNU pattern have constant size as imaging sensing component, huge scale image retrieval could be a terribly tough task.
