Authentication device including template validation and related methods

摘要

An authentication device may include a housing and a finger sensor carried by the housing and including first processing circuitry and a finger sensing area coupled thereto. The first processing circuitry may be configured to generate finger image data based upon a finger positioned adjacent the finger sensing area, and generate and store a first template based upon the finger image data. The authentication device may include second processing circuitry carried by the housing and configured to obtain the finger image data from the first processing circuitry. The second processing circuitry may be configured to generate a second template based upon the finger image data. The first processing circuitry may further be configured to obtain the second template from second processing circuitry, and validate the second template against the first template.

1. An authentication device comprising:
a housing; a finger sensor carried by said housing and comprising first processing circuitry and a finger sensing area coupled thereto and configured to
generate finger image data based upon a finger positioned adjacent said finger sensing area,encrypt the finger image data, andgenerate and store a first template based upon the finger image data, the first template including no finger image data; and second processing circuitry carried by said housing and configured to
obtain the encrypted finger image data from said first processing circuitry, andgenerate a second template based upon the encrypted finger image data, the second template including no finger image data, said first processing circuitry further configured to
obtain the second template from said second processing circuitry, andvalidate the second template against the first template.
