The pressures on today's system administrators to have secure systems are ever increasing. One area where security can be improved is in authentication. Face, retina, iris and sclera recognition, biometrics, provide one of the most secure methods of authentication and identification. These technologies are very useful in areas such as information security, physical access security, ATMs and airport security. These technologies are more or less accurate, easy to use, non-intrusive, and difficult

However, they do require the co-operation of the subject: need specific hardware and software to operate. These recognition technologies do provide a good method of authentication to replace the current methods of passwords, token cards or PINs and if used in conjunction with something the user knows in a two-factor authentication system then the authentication becomes even stronger.
