id-ear: biometric recognition based on response to acoustic stimulation

点击翻译按钮获取中文摘要

We propose to investigate and develop biometric systems that utilize biosignals generated from the human body as response to an acoustic stimulus applied to the human ear. In particular the signals considered as biometric modality will be the inner ear transient evoked otoacoustic emissions (TEOAE), recorded from the ear(s) via earphone(s). The proposed research will examine, analyze, and develop a cost-effective and privacy-oriented security solution to biometrically authenticate users in secure access control and remote monitoring application environments. The proposed framework constitutes an effective solution that utilizes a novel biometric cryptosystem to provide a realistic and feasible way to access and secure sensitive and/or personal information.TEOAE return signals have been shown to be distinctive and unique for different individuals and therefore are promising as biometric modalities. The revolutionary aspect of the proposed project is to realize that the use of stimuli provide additional security to the biometric application, revocability and active control of biometric by changing stimuli. Furthermore being a medical biometric, the TEOAE are less vulnerable to theft, attacks, cloning and other forms of circumvention, thus making the system more robust against unauthorized access. One of the key challenges is to demonstrate that these biometrics can perform accurately for large populations by establishing their uniqueness and permanence over time.The deliverables of this proposal will be cloud based and portable device solutions that will expand the frontiers in the areas of secure and revocable biometrics for personal, sensitive and private applications.
