  • System and/or method for image tamper detection
    Patent number: 8184850
    Abstract: The subject matter disclosed herein relates to techniques for detecting tampering of digital image data.
    Type: Grant
    Filed: August 6, 2010
    Date of Patent: May 22, 2012
    Assignee: New Jersey Institute of Technology
    Inventors: Yun-Qing Shi, Dongdong Fu
  • Apparatus and method for a generalized benford's law analysis of DCT and JPEG coefficients
    Patent number: 7940989
    Abstract: A method and apparatus for a novel statistical model based on Benford's law for the probability distributions of the first digits of the block-DCT and quantized JPEG coefficients. A parametric logarithmic law, the generalized Benford's law, is formulated. Furthermore, some potential applications of this model in image forensics, which include the detection of JPEG compression for images in bitmap format, the estimation of JPEG compression Q-factor for JPEG compressed bitmap image, and the detection of double compressed JPEG image. Experimental results demonstrate the effectiveness of the statistical model used in embodiments of the invention.
