GRAND seminar Minimizing Distortion in Information Hiding Abstract Information hiding refers to embedding data in a cover object (e.g. audio, images or video signal) by modifying the cover object. Information hiding techniques include watermarking, fingerprinting, fragile watermarking, steganalysis and steganography. These techniques have been used in a variety of applications, including copyright protection for digital media, content authentication, media forensics, and covert communications. The embedding procedure inevitably distorts the cover object and the distortion can be used to detect that the object contains hidden data in it. The goal of information hiding techniques is to minimize the embedding distortion. In this talk, I will present a brief overview of information hiding techniques. I will then present my own research on minimizing distortion in steganography and fragile watermarking. Biography Younhee Kim is a Ph.D candidate in Information Technology at George Mason University. Her areas of interest include steganography, steganalysis, watermarking, image processing and human computer interaction. Note This talk is based on "Towards Lower Bounds on Embedding Distortion in Information Hiding", Younhee Kim, Zoran Duric, Dana Richards. IWDW 2006: 362-376
