Café Scientifique with Dr Andrew Ker
Steganography - the art of concealing messages so they are only visible to sender and recipient - sounds like something out of a spy film, but is it realistic outside of fiction? Dr Andrew Ker researches the theory of hidden information, and will answer your questions about how messages can be hidden without arising suspicion, and why it is useful to be able to do so.
Dr Andrew Ker is a computer scientist based at University of Oxford. His research focusses on hiding information within digital media and detecting when there is hidden material.
