In this paper, a method of protecting a device from being identified through image capture is proposed. This method involves suppressing the device-related fingerprint, PRNU, in an image by modifying it in the domain of integer wavelet transform. The suppressed PRNU is then embedded into the image using reversible data hiding for perfect recovery of the original image. Extensive experiments on MICHE-I and VISION datasets demonstrate that this method addresses the shortcomings of existing techniques and exhibits strong scalability.
In this paper, we propose a method of protecting a device from being identified with the images captured by it. This method can suppress the device-related fingerprint, i.e., PRNU, in an image via modifying it in the domain of integer wavelet transform. In addition, we embed the suppressed PRNU into the image using reversible data hiding to achieve a perfect recovery of the original image. This is beneficial to solve the problems of device privacy leakage and terminal server identity authentication. Extensive experiments on MICHE-I and VISION datasets show that the proposed method makes up for the shortcomings of existing techniques and has strong scalability.
