ABSTRACT
 
 
 
The ever-increasing number of gadgets being used to create
digital content, as well as the easiness in sharing, editing,
and republishing this content, brings the problem of dealing
with a large amount of digital objects (e.g., images or
videos) whose content is very similar. Some issues faced by
investigators of digital crimes when analysing this type of
data include finding the original source of a suspect image,
for instance, and the responsible for first publishing it. It
is also challenging to determine how a set of similar objects
are related to each other. In this talk, I will briefly
introduce the research field of multimedia phylogeny, which
aims at automatically finding the underlying relationship
among groups of digital objects with similar content. This
relationship is represented by a tree structure, inspired by
the phylogenetic trees in Biology. I will present the
state-of-art approaches to reconstruct phylogenetic trees for
different media types, and also discuss some challenges faced
by this research field.
 
Short bio:
 
Marina A. Oikawa received the B.Sc. degree in computer science
from Federal University of Pará, Brazil, in 2006, and the
Master and PhD degrees in Engineering from Nara Institute of
Science and Technology, Japan, in 2010 and 2013,
respectively. Currently, she is a Postdoc at Institute of
Computing, University of Campinas, RECOD Lab. Her main
research interests include digital forensics, computer vision,
augmented reality, and computer graphics.
