Abstract
Systems and methods for authentication are provided. One system includes a device configured to sense electrical characteristics of an item coupled with a person and a memory storing a plurality of electrical signatures corresponding to measured electrical characteristics for a plurality of items. The system also includes a controller operable on a processor to determine if an electrical signature determined from sensed electrical characteristics of the item coupled with the person match one of the plurality of electrical signatures stored in the memory to authenticate the person having the item coupled thereto.
Claims24
A method for providing access control for users, the method comprising:
- creating a unique electrical signature for a user based on one or more electrical characteristics of a combination of the user and an item coupled to the user, including electrical characteristics of the item coupled to the user and electrical biometric characteristics of the user, wherein the one or more electrical characteristics are based on an interaction of an antenna with the combination of the user and the item coupled to the user;
- storing the unique electrical signature in a memory configured to store a plurality of electrical signatures;
- determining, with a processor, whether an acquired electrical signal matches the unique electrical signature;
- identifying a user if there is a match;
- and
- allowing access to a restricted area in response to determining whether the user is allowed to access to the restricted area.
A system comprising:
- a sensor pad having a device including an antenna embedded in a metal plate, the device configured to sense electrical characteristics of an item coupled to a user and positioned in proximity to the sensor pad;
- a dielectric cover on top of the antenna to define a sensing distance from the antenna to the item;
- and
- a controller operable on a processor to authenticate a person wearing the item using the sensed electrical characteristics of the item based on a determined self-inductance between the item and the antenna, the sensed electrical characteristics including electrical characteristics of the item coupled to the person and electrical biometric characteristics of the person.
A system comprising:
- a device comprising an antenna configured to sense electrical characteristics of a combination of a user and an item coupled with the user;
- a processor configured to create a unique electrical signature for the user based on the electrical characteristics;
- and
- a memory configured to store for a plurality of sensed electrical characteristics for a plurality of user, a plurality of such unique electrical signatures corresponding to measured electrical characteristics for a plurality of items, the unique electrical signatures based on electrical characteristics of the item coupled to the user and electrical biometric characteristics of the user.
