Abstract

Techniques for performing two-factor authentication in a process plant include receiving, at a user interface device, a first type of identification information for a user from an identification device or a physical trait of the user. The user interface device also receives a second type of identification information for the user from knowledge-based information provided by the user. The user interface device then determines that each type of identification information corresponds to the same authorized user within the process plant. When both types of identification information are for the same authorized user, the user is granted access to the user interface device. Accordingly, the user may execute functions on the user interface device to perform operations on a plant asset which is connected to the user interface device.

Claims20

Dependent claims

A method for providing two-factor authentication in a user interface device within a process plant, the method comprising:

receiving, at one or more processors in a user interface device, a first type of identification information for a user, wherein the user interface device includes integral input/output capabilities for connecting to a plant asset within a process plant;
receiving, at the one or more processors, a second type of identification information for the user;
comparing, by the one or more processors, each of the first and second types of identification information for the user to a plurality of types of identification information for a plurality of users who are authorized to access the user interface device;
and
providing, by the one or more processors, authorized access to the user when each of the first and seconds types of identification information correspond to a same authorized user;
wherein when the user has authorized access to the user interface device and the user interface device is connected to the plant asset, the user interface device is configured to communicate with the connected plant asset within the process plant.

3 more elements

A user interface device for providing two-factor authentication within a process plant, the user interface device comprising:

one or more processors;
an integral input/output component for connecting to a plant asset within a process plant;
and
a non-transitory computer-readable medium coupled to the one or more processors and the integral input/output component and storing instructions thereon, that when executed by the one or more processors, cause the user interface device to:
receive a first type of identification information for a user;
receive a second type of identification information for the user;
compare each of the first and second types of identification information for the user to a plurality of types of identification information for a plurality of users who are authorized to access the user interface device;
and
provide authorized access to the user when each of the first and seconds types of identification information correspond to a same authorized user;
wherein when the user has authorized access to the user interface device and the user interface device is connected to the plant asset, the user interface device is configured to communicate with the connected plant asset within the process plant via the integral input/output component.
