Radio frequency identification (RFID) is gaining in popularity, especially as we find ourselves in this communications age and headed towards a ubiquitous computing world. Automatic identification systems become an important aspect not just in today’s technology but also as part of our daily life. We need RFID in our cars,...

Role-based access control (RBAC) is a technology that is attracting a great deal of attention, particularly for commercial applications, because of its potential for reducing the complexity and cost of security administration in large networked applications. Under RBAC, security administration is greatly simplified by using roles,...

With its expanding array of applications in everything from biodiversity modeling to wireless communications, it's no wonder digital terrain modeling (DTM) - the electronic process of representing topography in three dimensions -- is a hot subject among engineers and geoscientists. This concise resource is the first truly complete guide...

The continuous developments of software-defined radio technology resulted in the appearance of the first real-time GPS software radios at the beginning of this century. For the first time, it was possible to realize a complete GNSS receiver without going into the depths of cumbersome hardware development that requires development or...

Many important GPS applications such as the positioning of wireless devices, tracking during ionospheric scintillation, and orbit determination of geostationary and high Earth orbit satellites require a GNSS (global navigation satellite system) receiver with the ability to work with weak signals. This first-of-its-kind book addresses this...

Digital identity can be defined as the digital representation of the information known about a specific individual or organization. Digital identity management technology is an essential function in customizing and enhancing the network user experience, protecting privacy, underpinning accountability in transactions and interactions, and...
