To guarantee the safety and privacy of citizens, institutions and enterprises are interested in using solutions based on biometric techniques to develop innovative service. An attempt was made to study, experiment, and evaluate the technologies and design methodologies suited to realize an intelligent distributed system for personal identification, recognition, and monitoring. They are based on multimodal, multiparadigmatic, multiagents, and adaptive-evolutionary technologies that take advantage of the synergy offered by every technology. The resultant approach is open to possible enhancement of the individual components that are used in the security system. These components include sensors, portable devices for collecting the biometric fea...
