In our electronically inter-connected society, reliable and user-friendly recognition and verification system is essential in many sectors of our life. The person’s physiological or behavioral characteristics, known as biometrics, are important and vital methods that can be used for identification and verification. Fingerprint recognition is one of the most popular biometric techniques used in ...

We discuss the co-design of integrated MEMS accelerometer array designed and fabricated onto the input of a CMOS charge amplifier. The focus of this paper is on two parts of the design flow: Firstly, advanced 3D process emulation and secondly, circuit simulation. We use a "voxel" (volumetric pixel) based process emulation tool that takes 2D masks and a description of the fabrication process, to...

− Accurate measurements of MEMS surfaces, geometries and motions are crucial to achieving the desired performance of the devices. The wide variety of MEMS devices in development and production requires very flexible metrology for single-platform characterization. In addition to having greatly varying geometries, devices must also be characterized statically and under actuation. White-light inte...

This research aims at enhancing the accuracy of land vehicular navigation systems by integrating GPS and Micro-Electro-Mechanical-System (MEMS) based inertial measurement units (IMU). This comprises improving the MEMS-based inertial output signals as well as investigating the limitations of a conventional Kalman Filtering (KF) solution for MEMS-IMU/GPS integration. These limitations are due to ...

Commercial CAD tools for MEMS have significantly contributed to the growth that the MEMS industry has experienced over the past two years by reducing development cycles and enabling the more rapid release of mature MEMS products. Unfortunately, the CAD for MEMS industry has focused primarily on device performance (for example, mechanical response due to electrostatic loading), with a concentrat...

Fingerprint recognition is widely used in security systems to recognize humans. In both industry and scientific literature, many fingerprint identification systems were developed using different techniques and approaches. Although the number of conducted research works in this field, developed systems suffer for some limitations partially those related the real time computation and fingerprint ...

According to the number of Internet in widely use and the development of the related application, the need of security system which can protect individual information has increased. Biometrics-based user authentication has several advantages over traditional password-based systems for standalone authentication applications. However, security of biometric data is particularly important as the co...

With the wide spread utilization of biometric identification systems, establishing the authenticity of biometric data itself has emerged as an important research issue. We present a fingerprint image watermarking method that can embed facial information into host fingerprint images. This scheme has the advantage that in addition to fingerprint matching, the recovered face during the decoding ca...
