Researchers say this combo of old-school invisible ink and AI is ‘uncrackable’
A team of researchers from the Harbin Institute of Technology in China have developed a system by which invisible ink and a basic cipher can be combined with relatively simple AI to create an ‘uncrackable’ offline encryption method. Up front:Remember when you learned that you could use lemon juice and water to write invisible messages on paper? Well, this is a lot like that. The researchers then take the invisible ink and use it to write a code that only an AI can break....
