Royal Society Café Scientifique events aim to provide a forum for the debate of scientific ideas. Free and open for all to attend, participants join scientists and other specialists to explore current issues in science over a drink. Audience participation is strongly encouraged.

This particular Royal Society Cafe Scientifique even is entitled 'Hiding in plain site' and will be lead by 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.

This event is part of a series of Café Scientifique events throughout the year.
