1. A system comprising:
- circuitry that in response to receiving user information generates a passcode from a passcode generator;
wherein the passcode generator is a value derived from earlier acquired user information associated with a user from which the user information is expected to have been received, and the passcode generator is a value from which deriving the earlier received user information is expected to be intractable.

Abstract
Protecting the security of an entity by using passcodes is disclosed. A passcode device generates a passcode. In an embodiment, the passcode is generated in response to receipt of user information. The passcode is received by another system, which authenticates the passcode by at least generating a passcode from a passcode generator, and comparing the generated passcode with the received passcode. The passcode is temporary. At a later use a different passcode is generated from a different passcode generator.

18. A system comprising:
-
an acquisition mechanism for acquiring biometric data;
an output unit;
passcode circuitry including at least an onboard memory; and
the passcode circuitry running embedded software, which configures the passcode circuitry for extracting information characterizing the biometric data, generating a registration code from the information, outputting the registration code via the output unit, generating a current passcode generator from the registration code, and storing the current passcode generator in the onboard memory. - View Dependent Claims (19)

20. A system comprising:
-
an acquisition mechanism for acquiring biometric data;
an output unit;
passcode circuitry including at least an onboard memory; and
the passcode circuitry running embedded software configures the passcode circuitry for implementing a method including at least in response to acquiring a new set of biometric data, authenticating the new set of biometric data, if the new set of biometric data matches information extracted from previously acquired biometric data, generating a passcode from a current passcode generator, generating a new passcode generator from the current passcode generator, replacing a value of the current passcode generator with a value of the new passcode generator, and storing the current passcode generator in the onboard memory wherein the current passcode generator includes at least the value of the new passcode generator.
