Abstract
A method for the identification of a user, especially in the case of devices of process automation technology, where at least one person-specific feature of the user is registered with a sensor and compared with stored features. In the case of a match of the registered, person-specific feature with at least one of the stored features, device access is granted.

A method for identification of a user, especially in the case of devices of process automation technology, comprising the steps of:
- requesting at least one person-specific feature of the user;
- registering the person-specific feature with a sensor;
- comparing the registered, person-specific feature with stored features;
- and
- granting access to the user upon matching of the registered, person-specific feature with one of the stored features.
An apparatus for the identification of a user, especially in the case of devices of process automation technology wherein at least one person-specific feature of the user is requested and compared with stored features, with access being granted when a match results from the comparison, comprising:
- at least one sensor:
- a programmable logic controller;
- and
- a data bus for connecting said at least one sensor to said programmable logic controller, wherein:
- said at least one sensor includes means for registering a person-specific feature of the user.
In combination with a device for the identification of a user for process automation technology, an apparatus comprising:
- a portable unit containing user-specific data;
- and
- a registration unit at the device, which reads user-specific data from said portable unit.
