Computer security tokens

Security tokens are widely used today for computer and network access. The most pervasive is the SecurID token from RSA, which is a keychain-attachable device that generates a time-synchronous unique sequence of numbers known as a one-time password (OTP).

The OTP works in conjunction with the employee's network username and password or PIN. A database tracks which token has been issued to each user, so that the organization knows who is accessing the protected system by determining which SecurID token was used. The OTP is significantly more secure than a traditional password, though it is still susceptible to security breaches if the device were stolen. It can be used without detection by anyone with access to the user's username and password.

The plusID security device from Privaris supports one-time password delivery and provides an additional security factor to computer security tokens, i.e. biometrics, to eliminate this risk. The plusID device is a personal, mobile, biometric device that incorporates OTP functionality.

The plusID device releases a one-time-password only after the user has successfully verified their identity with their fingerprint. The OTP is displayed on the LCD on the back of the plusID device and can be transmitted wirelessly, via a USB connection, or manually typed.

The plusID device adds an additional authentication factor to computer security tokens and offers enterprises an affordable and convenient three-factor authentication solution.
