Iris Protection with Verisimilar Feature Structure

Summary

With the huge advantages of iris in authentication and identification, research on protecting iris information in real-world applications has gradually become an important research topic. In this paper, a method to hide the real feature information of the iris is proposed. Such an algorithm aims to prevent iris information from being maliciously utilized otherwise there will be serious consequences. In particular, we focus on accurately manipulating the iris features and ensuring that this method can also prevent iris distortion, thus people could hardly pick out the difference between before and after modification with the naked eye. Furthermore, we verify and evaluate our method and its effect through similarity detection and feature matching. The results show that it has a good performance.
