Specifically, we show how to use the multiplicative nature of this component to derive a method enabling its estimation. Since this noise component is unique per sensor, consequently, the derived method is applied on digital image ballistics tasks in order to pinpoint the exact device that created a specific digital photo. Moreover, we enhance the method to be resistent to optical zoom and JPEG compression. cav_un_auth*0313206 IEEE International Symposium on Multimedia (ISM), 2013 Anaheim 09.12.2013-11.12.2013 CA 2015 IN RVO:67985556 http://hdl.handle.net/11104/0243061 S 2013 cav_un_epca*0439884 Proceedings of the IEEE International Symposium on Multimedia (ISM), 2013 978-0-7695-5140-1 241 247 Piscataway IEEE Computer Society 2013
