Abstract
A touch sensor is configured to sense a contact event occurring between a body part of a user and the touch sensor. The touch sensor is configured to produce contact data in response to the sensed contact event. A processor is coupled to the touch sensor and memory. The processor is configured to store in the memory a sequence of data frames each comprising contact data associated with a different portion of the user's body part. The processor is further configured to generate biometric signature data using the sequence of data frames.
Claims23
A processor-implemented method, comprising:
- sensing a contact event occurring between a body part of a user and a touch sensor;
- storing in a memory, for the contact event, a sequence of data frames, each of the data frames comprising a three-dimensional data set comprising two-dimensional contact data and a time-dependent reference associated with a contact pattern that evolves over time during contact between different portions of the user's body part and the touch sensor;
- measuring pressure exerted at different locations of the touch sensor by the user's body part during the contact event;
- and
- generating, by a processor, biometric signature data using the three-dimensional data sets of the sequence of data frames and the measured pressure.
An apparatus, comprising:
- a touch sensor configured to sense a contact event occurring between a body part of a user and the touch sensor, the touch sensor configured to produce contact data and sense pressure in response to the sensed contact event;
- and
- a processor coupled to the touch sensor and memory, the processor configured to store in the memory a sequence of data frames, each of the data frames comprising a three-dimensional data set comprising two-dimensional contact data and a time-dependent reference associated with a contact pattern that evolves over time during contact between different portions of the user's body part and the touch sensor, the processor also configured to measure pressure exerted at different locations of the touch sensor by the user's body part during the contact event, and the processor further configured to generate biometric signature data using the three-dimensional data sets of the sequence of data frames and the measured pressure.
A processor-implemented method, comprising:
- sensing a contact event occurring between a body part of a user and a touch sensor;
- capturing two-dimensional contact data in response to sensing the contact event;
- triggering acquisition of individual data frames of a sequence of data frames in response to triggering events, the triggering events based on the captured contact data;
- measuring pressure exerted at different locations of the touch sensor by the user's body part during the contact event;
- storing in a memory, for each data frame, a three-dimensional data set comprising two-dimensional contact data and a time-dependent reference;
- and
- generating, by a processor, biometric signature data using the three-dimensional data sets of the sequence of data frames and the measured pressure.
