In this paper, we analyze and analytically describe the multiplicative deterministic noise component of imaging sensors in a novel way. 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.
