Advances in Information Processing and Protection

The Computer Science is relatively new field which is developing very fast not only because due to the huge interest of scientists and the market request, but also because this science has created possibilities for people of investigation and solved many problems that some time ago seemed to be insolvable. Such problems had only been described in science fiction novels, like underwater journeys of captain Nemo described by Jules Verne in XIX century. At present, various human dreams are successively becoming reality exactly as the underwater journeys became possible in the XX century. The proposed book gives you a view of the progress in such domains of Computer Science as Artificial Intelligence, Biometrics, Security of Information Technology, Computer Information Systems and Industrial Management. The works contained in the book describe the newest investigation results of devoted scientists from Europe and Asia. The book is written in a hard scientific language. It is really valuable and I am sure it will deliver you many scientific benefits.

They are:

This book contains a selection of the best papers given at the international Advanced Computer Systems Conference in October 2006 in Miedzyzdroje, Poland.  Combining research areas from both Computer Science and Industrial Management, the book is partitioned into four topical areas:

Artificial Intelligence

Computer Security and Safety

Image Analysis, Graphics and Biometrics

Computer Simulation and Data Analysis

The Artificial Intelligence section considers results of the science and engineering of making intelligent algorithms and computer programs.  This section includes papers on Humatronics, Fuzzy Logic, Robotics, Cell, Genetic and Probabilistic Algorithms, Incomplete Data and Similarity Relations, and Fast Neural Networks.

The Computer Security and Safety section covers a wide range of issues, including Error Detection in Block Ciphers, Parallelization of Encryption Algorithms, Visual Cryptography Methods, Neural Network for Building Programmable Block Ciphers, Security and Safety in Distributed Computing Environments, and Chaotic Product Cipher.

The Image Analysis, Graphics and Biometrics section deals with difficult tasks studying the extraction of meaningful information from images as well as methods for uniquely recognizing humans based upon one or more intrinsic physical or behavioral traits.  Included are chapters dealing with Word Recognition, Signature Identification, Fingerprint Recognition, and Biometric Image Pre-classification.

The Computer Simulation and Data Analysis section concerns computer programs that attempt to simulate an abstract model of a particular system and transform data with the aim of extracting useful information and facilitating conclusions.  It includes papers devoted to Processor Utilization on Multi-Processor Systems, Computer-based Training Systems for Operators of Dynamic Objects, Linked Computer Servers, Loops Parallelization in the .NET Environment to be used for simulation purposes, and related topics.
