SPS-IFS TC Webinar: Progressive JPEGs in the Wild: Implications for Information Hiding and Forensics

Date: 9 November 2023
Time: 10:00 AM ET (New York Time)
Presenter(s): Ms. Nora Hofer

SPS-IFS (Information Forensics and Security Technical Committee) Webinar

Abstract

JPEG images in progressive mode have become more prevalent in recent years. Presumably, this surge is caused by the adoption of MozJPEG, an open-source library designed for web publishers. So far, the optimizations used by MozJPEG have not been considered by the multimedia security community although, they are highly relevant.  In this talk, we will delve into these optimizations and discuss their implications for steganography, steganalysis, and image forensics.

Biography

Nora Hofer is a Ph. D. student in the Security & Privacy Lab at the University of Innsbruck in Austria. She is a scientific member of the EU Horizon 2020 UNCOVER project on the development of a steganalysis framework. She received the award for the "Best Student Paper" for her latest publication "Progressive JPEGs in the Wild" at the IH&MMSec '23 conference, where she looked under the hood of the MozJPEG codec and investigated the implications for information hiding and forensics. Her research interests are digital image forensics and compression algorithms.
