  With rapid development of computer techniques, the human computer interaction
scenarios are becoming more and more frequent. The development history of the
human-computer interaction is from a person to adapt to the computer to the
computer and continually adapt to the rapid development. Facing the process of
human-computer interaction, information system daily operation to produce huge
amounts of data, how to ensure human-computer interaction interface clear,
generated data safe and reliable, has become a problem to be solved in the
world of information. To deal with the challenging, we propose the information
security enhancement approaches and the core applications on HCI systems.
Through reviewing the other state-of-the-art methods, we propose the data
encryption system to deal with the issues that uses mixed encryption system to
make full use of the symmetric cipher algorithm encryption speed and encryption
intensity is high while the encryption of large amounts of data efficiently.
Our method could enhance the general safety of the HCI system, the experimental
result verities the feasibility and general robustness of our approach.
