Abstract

Steganalysis aims to identify those changes performed in a
specific media with the intention to hide information. In this
paper we assess the efficiency, in finding hidden information,
of several local feature detectors. In the proposed 3D ste-
ganalysis approach we first smooth the cover object and its
corresponding stego-object obtained after embedding a given
message. We use various operators in order to extract lo-
cal features from both the cover and stego-objects, and their
smoothed versions. Machine learning algorithms are then
used for learning to discriminate between those 3D objects
which are used as carriers of hidden information and those
are not used. The proposed 3D steganalysis methodology is
shown to provide superior performance to other approaches
in a well known database of 3D objects.
