The research in my lab for the past 15 years has focused on developing techniques for detecting photo tampering. I am co-founder of Fourandsix Technologies and the new website izitru.com. Ask me anything related to image forensics, our work on photoDNA, our photo authentication site izitru.com, or anything else that you’d like.
