Abstract: Based on the principle of pattern recognition, a robust method for source camera identification is proposed by using imaging sensor. The characteristics of imaging process of the camera are analysed, and a robust classifier is constructed to determine the brand/model of the camera by extracting noise statistical features of imaging sensor. The proposed features include image denoising difference，statistical moment of wavelet sub-bands and color feature. Experimental results demonstrate that the design of classifier can effectively identify the correct camera brand/model with good robustness.
