Exhibition "Public secrets"

Exhibiton “Public secrets” The protection of personal data is an increasingly hot theme and while a few steps have been taken in legislative matters, there are still many open problems. Innovative technologies based on mathematical algorithms are in our help: in particular cryptography, thanks to which a text is transformed into a set of signs and absolutely meaningless symbols (for those who do not know the right key to decrypt them). In this exhibition you will discover the history and mechanisms of cryptography, of steganography (the art of hiding messages) and of cryptocurrencies, virtual currencies (like Bitcoin) based on cryptographic techniques. In short: protection of personal data, project Privacy Flag, spartan scytale, Caesar, Vigenere and Vernam ciphers, Alberti's disk, Enigma machine, visual cryptography, Tor, Bitcoin, invisible ink and finally thematic games!
