Authentication and authorization are the cornerstones of any well-implemented security policy. Simple passwords are rarely sufficient, and as organizations grow, control is quickly lost and administration and maintenance become a nightmare. Developing a comprehensive strategy that includes biometric, token, and public key infrastructure (PKI) technologies is imperative for assuring authentication and data integrity.

The four principal forms of Authentication are:

• "What you know" - password and passphrases
• "What you have" - tokens including physical keys and smart cards
• "What you are" - static biometrics such as fingerprint, iris, and face recognition
• "What you do" - dynamic biometrics such as voice and signature recognition

Whether it is through authentication technologies involving hardware such as tokens or software-based certificates and biometric identification, I/O Software provides clients with the appropriate authentication mechanism and technologies to meet their needs.

This section provides a reference point for a wide range of authentication and security related technologies. I/O Software products offer tight and modular integration for all of the technologies discussed in this section, although we do not directly develop these technologies. However, I/O Software has partnered with the industry's leading companies to integrate their technologies and bring them to market.
