AN EFFECTIVE SWARM INTELLIGENCE BASED PASSIVE BIOMETRIC CONTINUOUS AUTHENTICATION SYSTEM

Abstract

Swarm intelligence (SI) is the collective behavior of decentralized, self- organized systems, natural or artificial. Systems consist typically of a population of simple agents or boids interacting locally with one another and with their environment. The inspiration often comes from nature, especially biological systems. The agents follow very simple rules, and although there is no centralized control structure dictating how individual agents should behave, local, and to a certain degree random, interactions between such agents lead to the emergence of "intelligent" global behavior, unknown to the individual agents. Examples in natural systems of SI include ant colonies, bird flocking, animal herding, bacterial growth, fish schooling and microbial intelligence.
