Abstract
A device can include a fingerprint reader that generates fingerprint data representative of a fingerprint of a finger; circuitry that authenticates the fingerprint via an authentication process and that identifies a change of the fingerprint based at least in part on the generated fingerprint data and historical fingerprint data; and circuitry that, responsive to the identification of the change of the fingerprint, revises the authentication process based at least in part on at least a portion of the received fingerprint data.
Claims17
A device comprising:
- a fingerprint reader that generates fingerprint data representative of a fingerprint of a finger;
- circuitry that authenticates the fingerprint via an authentication process that fails generated fingerprint data of a first read by a comparison to a recognition dataset and passes generated fingerprint data of a subsequent read by a comparison to the recognition dataset, and that identifies a change of the fingerprint that is less than a threshold based at least in part on the generated fingerprint data of the first read;
- and
- circuitry that, responsive to the authentication of the fingerprint and the identification of the change of the fingerprint that is less than the threshold, revises the authentication process by adding at least a portion of the generated fingerprint data of the first read to the recognition dataset.
A method comprising:
- performing an authentication process that comprises
- receiving first fingerprint data representative of a fingerprint of a finger,
- failing to authenticate the fingerprint using the first fingerprint data and a recognition dataset,
- receiving subsequent fingerprint data representative of the fingerprint of the finger, and
- authenticating the fingerprint using the subsequent fingerprint data and the recognition dataset and identifying a change of the fingerprint that is less than a threshold based at least in part on the received first fingerprint data;
- and
- responsive to the authenticating the fingerprint and the identifying the change of the fingerprint that is less than the threshold, revising the authentication process by adding at least a portion of the first fingerprint data to the recognition dataset.
One or more processor-readable storage media comprising processor-executable instructions that instruct a device to:
- perform an authentication process that comprises
- reception of first fingerprint data representative of a fingerprint of a finger,
- failure to authenticate the fingerprint using the first fingerprint data and a recognition dataset,
- reception of subsequent fingerprint data representative of the fingerprint of the finger, and
- authentication of the fingerprint using the subsequent fingerprint data and the recognition dataset and identification of a change of the fingerprint based at least in part on the received first fingerprint data;
- and
- responsive to the authentication of the fingerprint and the identification of the change of the fingerprint, revise the authentication process by adding at least a portion of the first fingerprint data to the recognition dataset.
