Abstract

User identification is becoming more and more important for Apps on mobile devices. However, the identity recognition based on eyes, e.g., iris recognition, is rarely used on mobile devices comparing with those based on face and fingerprint due to its extra cost in hardware and complicated operations during recognition. In this article, an eye-based recognition method is designed for identity recognition on mobile devices, which can be implemented just like face recognition. In the proposed method, the eye feature is composed of the static and dynamic features, where the periocular feature extracted by deep neural network from the eye image is used as the static feature, and the motion feature of saccadic velocity is selected as the dynamic feature. The eye images can be captured by the normal camera on mobile devices just like faces, and dynamic features can provide living information to increase the difficulty of forgery. The GazeCapture dataset is used to test the proposed method, because the eye images in this dataset are captured by mobile devices during daily use. The recognition accuracy of the proposed method on the GazeCapture dataset can reach 96.87% only based on the periocular feature and can be enhanced to 97.99% when it is fused with the saccadic feature. The experiment results show that the performance of the proposed method can be comparative to that of iris recognition methods. It demonstrates that the proposed method is a practical reference for the eye-based identity recognition, and the proposed method provides one more biometric choice for mobile devices.
