Dr. Si Chen is looking forward to studying practical solutions for securing biometric-based mobile authentication. A lot of interesting yet challenging problems remain to be fully explored, including designing a secure mechanism to defend against biometric-based impersonation attacks (e.g. voice impersonation attacks) on smartphones. View Dr. Chen's 1-minute video detailing the issue.
Given the fact that there is a natural demand for users to control their mobile device in a convenient and non-intrusive way, many biometric-based mobile authentication applications have been developed. However, the human biometrics, e.g. human voice and human face, are often exposed to the public in many different scenarios.
Traditional security mechanisms for these biometric authentication systems focus on data encryption and other post-processing techniques, but the biometric themselves often remain vulnerable to attacks in the physical/analog domain. If an adversary captures and manipulates a physical/analog signal prior to digitization, no amount of digital security mechanisms after the fact can help. Fortunately, nature imposes fundamental constraints on how these analog signals can behave.
Dr. Chen's research is currently focused on studying the sensor-assisted mobile physical challenge-response authentication scheme to protect mobile authentication systems against impersonation attacks occurring in the physical/analog domain.
The West Chester University Computer Science Department, within the College of Sciences & Mathematics, provides access, through education and state-of-the-art technology, to the ever-growing professional opportunities available in the fields of Computer Science. The Computer Science Bachelor of Science Program is accredited by the ABETComputing Accreditation Commission.
The Computer Science Department is home of the Information Security Center whose efforts have established West Chester University as a National Center for Academic Excellence in Cyber Defense Education. The Department is a member of Pennsylvania Association of Computer & Information Science Educators (PACISE).
We are excited to announce the creation of an accelerated Bachelor/Master of Science program. Undergraduates with 90+ credits and a 3.0+ GPA can apply and receive both degrees in 5 years. See more details.
