Abstract
Technology is described for authenticating a user based on a wrist vein pattern. A wrist contact sensor device detects a wrist vein pattern. The wrist contact sensor device may be wearable by being positioned by a wearable support structure like a wristband. One or more pattern recognition techniques may be used to identify whether a match exists between a wrist vein pattern being detected by the sensors and data representing a stored wrist vein pattern. A user may be authenticated based on whether a match is identified satisfying matching criteria.
Claims17
A wrist contact sensor device for capturing a wrist vein pattern comprising:
- at least one illuminator positioned in the device for contacting skin of a user on a palmar side of the wrist and directing infrared illumination into the palmar wrist skin;
- the at least one illuminator being controlled by illumination drive circuitry under control of one or more communicatively coupled processors;
- a plurality of sensors positioned in the device for contacting the skin of the user on the palmar side of the wrist, the plurality of infrared sensors detecting reflections and generating detection signals based on the detected reflections;
- sensor interface circuitry supported by the support structure and interfacing with the plurality of sensors for receiving the detection signals and generating digital data representing a wrist vein pattern for the user based on the detection signals;
- and
- the sensor interface circuitry sending the digital data representing the wrist vein pattern to the one or more communicatively coupled processors.
A method of authenticating a user based on data representing a wrist vein pattern comprising:
- illuminating skin on a palmar side of a wrist with infrared (IR) illumination from one or more (IR) illuminators of a wrist contact sensor device;
- generating detection signals representing infrared reflections detected by one or more (IR) sensitive sensors of the wrist contact sensor device, the sensors being in contact with the skin of the palmar side of the wrist;
- generating digital data representing a wrist vein pattern based on the detection signals;
- and
- sending the digital data to a communicatively coupled computer system having access to reference wrist vein pattern data.
A method of authenticating a user based on data representing a wrist vein pattern comprising:
- receiving by one or more computer systems the digital data representing the wrist vein pattern from a wrist contact sensing system;
- automatically comparing the digital data representing the wrist vein pattern with digital data representing one or more reference wrist vein patterns using one or more pattern recognition techniques for identifying a matching reference wrist vein pattern satisfying a matching criteria;
- responsive to finding a matching reference wrist vein pattern, automatically assigning an identity stored for the matching reference wrist vein pattern to a user associated with the received digital data representing the wrist vein pattern;
- and
- notifying one or more executing applications requesting user authentication of the assigned identity of the user.
