  • Method for estimating an improved camera fingerprint by identifying low-mass pixel positions and correcting corresponding fingerprint values
    Patent number: 10868984
    Abstract: An improved method of determining a camera fingerprint and matching fingerprints is provided. A pixel-wise mass is defined and pixel positions having a low pixel-wise mass are identified. Once identified, the fingerprint values associated with those pixel positions are exchanged with statistically distributed random fingerprint values. Because the replacement values are statistically distributed, an improved fingerprint is provide resulting in improved accuracy of fingerprint matching.
