I am a fourth year Computer Science and Physics dual major at Lake Forest College. I'm from Salt Lake originally but for some reason wound up in Chicago for college.Working in Logan provided a nice balance for me as I could enjoy the small town atmosphere and living in Logan, while still being able to visit my family.
While small Logan had more than enough activites to keep me busy. I was even able to find a martial arts dojo close to campus where I could practice.
Project
This summer I worked with steganography or the practice of hiding messages in Images. My project centered around determining new ways to detect these embedded messages. I worked primarily with the research done by Jessica Fridrich in Feature-Based Steganalysis for JPEG Images and its Implications for Future Design of Steganographic Schemes where the detection of embedded data is driven by 23 featrures extracted from the image. I created 66 new features and test their effectiveness in detecting embedded messages.Results
I developed two new types of features. Features based off the patterns of noise in the image, and features based on approximating the quantiezed DCT histogram of the image. When I combined the noise features with the original 23 features i was able to improve the detection of embedded messages by ~9%More in depth results can be found in my final presentation or final project.
