  Abstract: Steganography has advanced tremendously in the last few years and simple concepts have even been presented on mainstream TV. However, more sophisticated techniques are less well-known and may be overlooked by forensic analysts and even Steganalysis software. This presentation will showcase several more advanced (and some unpublished) steganographic techniques, some with a very high data hiding capacities. One technique successfully hides 15% to 20% of data in a jpeg and YOU can't tell! That means your 8 MB jpeg image may contain 1.6 MB of covert data! An audio CD contains about 700 MB of data – even a modest 1% capacity allows for 7 MB of data. The presentation embeds working demonstrations of several steganographic software programs so YOU can decide the effectiveness for yourself. Can you see or hear it? Will it be flagged by Steganalysis programs? We shall see … or not!
