..."The ego is that part of the id which has been modified by the direct influence of the external world ... The ego represents what may be called reason and common sense, in contrast to the id, which contains the passions ... in its relation to the id it is like a man on horseback, who has to hold in check the superior strength of the horse; with this difference, that the rider tries to do so with his own strength, while the ego uses borrowed forces". [Freud, The Ego and the Id (1923)]

EGO - the Latin means "I, myself" and in our nomenclature this means the subject, the owner and the identity of an individual within a larger group. In the EGO system the identity of an individual is linked to that person's rights and property via a biometric mechanism so private and so discerning that ownership is absolute and inviolable.

The EGO system is extensible for reasons of pragmatism to lower levels of authentication and is capable of application to the world of Things as well as persons.

The EGO model is structured to meet the needs of security conscious individuals in a domestic environment and to extend easily to satisfy the requirements of large corporate and industrial arenas.

EGO has modular interfaces to legacy systems but sets a new standard in simplicity of installation and intuitive system management it is a growing family of interchangeable modules based on Internet Protocols and single cable connectivity.
