摘　　要：The biometric person authentication technique based on the pattern of the human iris is well suited to be applied to any access control system requiring a high level of security. With the wide spread utilization of biometric identification systems, establishing the authenticity of biometric data itself has emerged as an important research issue. In this paper, we propose an efficient iris feature watermarking technique that can embed face image as the watermark information into host iris images. This scheme has the advantage that in addition to iris pattern matching, the recovered face during the extraction can be used to establish the authenticity of the iris and the user. The scheme is strong enough to resist malicious manipulations of an iris image including diverse attacks. Experiments are conducted to show the robustness of this technique. Moreover, cryptography tools, such as digital signature and timestamp, are introduced to make security proving publicly verifiable. Finally, our scheme does not introduce any significant degradation in the iris pattern matching performance.
