Flexible Visual Display Units as Security Enforcing Component for Contactless Smart Card Systems
Today, one existing class of RFID systems are based on ISO 14443 (Proximity Coupling). This is the standard for RF-interfaces of contactless smart card systems. Contactless RF interfaces of smart cards are very often regarded as less secure than contact based smart cards. This tenor may be changed based on our new approach. Therefore we suggest to establish secure password authenticated wireles...
متن کاملOptical Contactless Testing
2 0740-7475/06/$20.00 © 2006 IEEE Copublished by the IEEE CS and the IEEE CASS IEEE Design & Test of Computers WITH DECREASING FEATURE SIZE and increasing chip densities, the classical mechanical probe approach for internal fault detection and functional testing faces increasing challenges. Mechanical probes have limitations because of their relatively large size and inherent parasitic effects....
متن کاملContactless hand recognition
Traditional hand geometry-based systems use low-resolution cameras or scanners to capture users’ hand images with the help of peggies or by forcing them to touch a screen. Those systems measure a hand shape to extract its features, like lengths and widths of fingers, and hand contour, for recognition. Unfortunately, traditional techniques face unsolved problems: low discriminability due to low-...
متن کاملContactless inductive flow tomography.
The three-dimensional velocity field of a propeller-driven liquid metal flow is reconstructed by a contactless inductive flow tomography. The underlying theory is presented within the framework of an integral equation system that governs the magnetic field distribution in a moving electrically conducting fluid. For small magnetic Reynolds numbers this integral equation system can be cast into a...
متن کاملTowards contactless palmprint authentication
This study examines the issues related to two of the most palmprint promising approaches applied to the contactless biometric authentication and presents a performance evaluation on three different scenarios. The presence of significant scale, rotation, occlusion and translation variations in the contactless palmprint images requires the feature extraction approaches that can accommodate such w...
