Raid technology Privacy of personal data is an illusion in today’s complex society. With only passwords, or Social Security Numbers as identity or security measures every one is vulnerable to invasion of privacy or break of security.  Traditional means of identification are easily compromise and enyone can use this information to assume another’s identity.  Sensitive personal and corporate information can be assessed and even criminal activities can be performed using another name.        Eye pattern recognition system provides a barrier to and virtually eliminates fraudulent authentication and identity privacy and safety controls privileged access or authorised entry to sensitive sites, data or material.  In addition to privacy protection there are myriad of applications were iris recognition technology can provide protection and security.  This technology offers the potential to unlock major business opportunities  by providing high confidence customer validation.     Unlike other measurable human features in the face, hand, voice or finger print, the patterns in the iris do not change overtime and research show the matching accuracy of iris recognition systems is greater than that of DNA testing.  Positive identifications can be made through glasses, contact lenses and most sunglasses.  Automated recognition of people by the pattern of their eyes offers major advantages over conventional identification techniques.  Iris recognition system also require very little co-operation from the subject, operate at a comfortable distance and are virtually impossible to deceive.  Iris recognition combines research in  computer vision, pattern recognition and the man-machine interface.  The purpose is real-time, high confidence recognition of a persons identity by mathematical analysis of the random patterns that are visible with in the iris.  Since the iris is a protected internal organ whose random texture is stable throughout life, it can serve as a ‘living password’ that one need not remember but one always carries
