Description
I was puzzled when a friend sent me a Buffy the Vampire Slayer picture out of the blue but, knowing that friend is an oddball, thought nothing of it. Days later, again without warning, a Babylon 5 picture. A few days after that a picture from Firefly. Then he repeated the pictures. A cryptic comment led me to understand that there was more to them than met the eye. Come learn the history, applications, and math behind crypto steganography how unravelling the mystery of the pictures culminated in the resolution of a 15 year rivalry when the US Olympic men’s curling team won the gold in 2018.

In Sean Marcia's talk at RailsConf 2022 titled 'Pictures Of You, Pictures Of Me, Crypto Steganography', he explores the intriguing blend of storytelling and crypto steganography, sharing a personal anecdote that highlights this technique. The presentation begins with an introduction to two identical Swedish hockey players, the Sedin brothers, which serves as a metaphor for the uniqueness of individuals despite the shared traits. Marcia then transitions to the main topic of steganography, explaining how it has evolved over centuries from ancient methods of hiding messages to modern digital techniques. Key points discussed throughout the presentation include: - **Definition of Steganography**: Marcia defines crypto steganography as concealing information within other data, emphasizing that it is rooted in the Greek words for 'hiding' and 'writing'. - **Historical Context**: The talk covers various historical examples, such as the use of wax tablets in ancient Greece and invisible ink during wartime. - **Modern Applications**: Modern steganography often involves digital images, where information can be embedded within the least significant bits of pixel data without noticeable changes to the image quality. - **Personal Anecdote**: Marcia shares a fun story about receiving cryptic images from a friend, which initially seemed like an odd joke but turned out to involve hidden messages that related to a competitive curling rivalry between the U.S. and Canadian teams leading up to the 2018 Olympics. - **Culmination of Rivalry**: The resolution of this comedic rivalry is tied to the U.S. curling team winning gold at the 2018 Olympics, a significant point for Marcia given his competitive history in curling. Throughout the presentation, Marcia offers humor and insight, using his experiences with curling as a lens through which to understand competition, friendship, and the clever use of cryptography in playful challenges. He concludes by reflecting on how humor and creativity can turn even competitive rivalries into enjoyable experiences, while also inviting the audience to explore the fascinating world of steganography. ### Key Takeaways: - Crypto steganography is a fascinating field that combines the art of hiding information with mathematical principles. - The evolution of steganography reflects human creativity and the desire for secure communication. - Personal stories can effectively engage audiences and illustrate complex ideas in relatable ways.
