It’s a lot more chemistry than I understand: Invisible inks based on “smart” fluorescent materials have been shining brightly (if only you could see them) in the data-encryption/decryption arena lately…. But some of the materials are costly or difficult to prepare, and many of these inks remain somewhat visible when illuminated with ambient or ultraviolet … Read More “New Research in Invisible Inks” »
Interesting: “We used silver and carbon ink to print an image consisting of small rods that are about a millimeter long and a couple of hundred microns wide,” said Ajay Nahata from the University of Utah, leader of the research team. “We found that changing the fraction of silver and carbon in each rod changes … Read More “Hiding Information in Silver and Carbon Ink” »
There’s new malware toolkit that uses steganography to hide in images: For the past two months, a new exploit kit has been serving malicious code hidden in the pixels of banner ads via a malvertising campaign that has been active on several high profile websites. Discovered by security researchers from ESET, this new exploit kit … Read More “WWW Malware Hides in Images” »
Research on color-changing materials: What do squid and jellyfish skin have in common with human skin? All three have inspired a team of chemists to create materials that change color or texture in response to variations in their surroundings. These materials could be used for encrypting secret messages, creating anti-glare surfaces, or detecting moisture or … Read More “Friday Squid Blogging: More Research Inspired by Squid Skin” »
In Colombia: The team began experimenting with Morse code using various percussion instruments and a keyboard. They learned that operators skilled in Morse code can often read the signals at a rate of 40 words per minute but played that fast, the beat would sound like a European Dance track. “We discovered the magic … Read More “Hiding a Morse Code Message in a Pop Song” »
