Statistical DNA Forensics: Theory, Methods and Computation

Statistical and Geometric Methods for Passive-blind Image Forensics

Statistical and Geometric Methods for Passive-blind Image Forensics Tian Tsong Ng Passive-blind image forensics (PBIF) refers to passive ways for evaluating image authenticity and detecting fake images. This dissertation proposes a physics-based approach for PBIF, with our definition of image authenticity derived from the image generative process comprising the 3D scene and the image acquisitio...

DNA Computation: Theory, Practice, and Prospects

L. M. Adleman launched the field of DNA computing with a demonstration in 1994 that strands of DNA could be used to solve the Hamiltonian path problem for a simple graph. He also identified three broad categories of open questions for the field. First, is DNA capable of universal computation? Second, what kinds of algorithms can DNA implement? Third, can the error rates in the manipulations of ...

Statistical Tools for Digital Forensics

A digitally altered photograph, often leaving no visual clues of having been tampered with, can be indistinguishable from an authentic photograph. As a result, photographs no longer hold the unique stature as a definitive recording of events. We describe several statistical techniques for detecting traces of digital tampering in the absence of any digital watermark or signature. In particular, ...
