On the basis of analysis

investigation

and modification of existing imaging device identification algorithm

a robust method for source camera identification is proposed based on imaging sensor features.Based on the principle of pattern recognition

the characteristics of imaging process of the camera is analyzed

and a robust classifier is constructed to determine the brand/model of the camera by extracting noise’s statistical features of sensor.The proposed features include image denoising subtraction and wavelet analysis.Experimental results demonstrate that the design of classifier can effectively identify the correct camera brand/model with good robustness.
