Cryptography for Human Senses

Kimmo Halunen and Outi-Marja Latvala


Cryptography is a key element in establishing trust and enabling services in the digital world. Currently, cryptography is realized with mathematical operations and represented in ways that are not accessible to human users. Thus, humans are left out of the loop when establishing trust and security in the digital world. In many areas the interaction between users and machines is being made more and more seamless and user-friendly, but cryptography has not really enjoyed such development. In this paper, we present ideas that could make cryptography more accessible to humans. We review previous research on this topic and some results that have been achieved. We propose several topics and problems that need to be solved in order to build cryptography for human senses. These measures range from practical implementations of existing methods and utilising a wider range of human senses all the way to building the theoretical foundations of this new form of cryptography.
