Although the exact details of what the supposed russian agents embedded in the pictures , and how they did it , remains classified , the basic technique involves changing the numeric code that computers assign to colors , explained tal malkin , an assistant professor in columbia university 's cryptography laboratory .
They stole information from a research version of a system made by id quantique , a swiss firm that is trying to commercialise quantum cryptography , by taking advantage of synchronisation signals that pass between alice and bob .
Now , six years later , " the lost symbol " is out -- and so too is our book , which I wrote with co-author arne de keijzer , with assistance from more than three dozen expert contributors in fields from theology to cryptography .
The three , wojciech mazurczyk , maciej karas and krzysztof szczypiorski , who all work at the warsaw university of technology , made use of a technique called steganography , cryptography 's lesser-known , less glamorous cousin .
