This work is on biometric data indexing for large-scale identification systems with a focus on different biometrics data indexing methods. It provides state-of-the-art coverage including different biometric traits, together with the pros and cons for each. Discussion of different multimodal fusion strategies are also included.

The Java programming language has been one of the most powerful tools available to computer programmers since its inception in 1995. It has also consistently changed since then, making it a vast and powerful resource for object-oriented programming today. This lucid textbook introduces the student not only to the nuances of object-oriented programming, but also to the many syntaxes and semantics of the modern Java language. Each concept of programming is explained, and then illustrated with small but effective ready-to-run programs. Important points to be noted have been emphasized and hints have been given at the end of each discussion so that programmers are careful to avoid common pitfalls. Finally, a number of practice problems taken from real world scenarios encourage the student to think in terms of problem solving, consolidating the knowledge gained.
