PKI Key Generation Based on Iris Features

In this paper, an iris feature-based PKI key generation is proposed. Contributions include a general approach for distinguishable iris feature generation and a PKI key generation mechanism. The proposed method differs from prior work of using pseudo random number to generate cryptographic keys. Thereby, a longer and more distinguishable bitstream can be generated for PKI key generation. Experiments are performed on one iris database to verify the feasibility of the proposed method.
